Which type of wave has points called nodes that do not move ?

A standing wave, also known as a stationary wave, is a wave that has a point called a node and does not move. Stationary waves are formed when two opposing waves that have identical frequencies and are traveling in mediums that are moving in opposite directions combine. In a stationary wave, each point on the axis has a constant amplitude. The nodes of a standing wave are areas at which the amplitudes are at a minimum. The locations on a standing wave where the amplitude is at a maximum are called antinodes. Standing waves can be formed by transverse waves, such as those created along a string. However, standing waves can also be formed by longitudinal waves, such as those formed within an air column.

Which of these events resulted from the end of iconoclasm during the Macedonian Dynasty? A. New freedoms granted to painters led to a rebirth of...

During the 8th and early 9th centuries, Byzantium was under the control of emperors who believed in iconoclasm---the belief that all religious images are sacrilegious and must be destroyed. As a result, many sculptures and works of art were destroyed, and there was little incentive for artists to create new ones, because those too would likely be destroyed if they had even the remotest religious themes.

But starting in the mid 9th century and continuing until the 11th century, Byzantium's government changed, starting with Emperor Michael III and then continuing into what is called the Macedonian Dynasty, a series of emperors who were ethnically Macedonian. During this period, iconoclasm was repudiated and the government began funding and protecting works of art, including religious art, that previously would have been destroyed.

This makes the best answer A: New freedoms granted to artists resulted in a flourishing of new Byzantine art where it had previously been suppressed.

In Shakespeare's Othello, how does Othello blame Desdemona for doing bad things?

In Shakespeare's Othello, Othello blames Desdemona for supposedly being unfaithful to him by continually calling her a "strumpet," or in other words a whore.  When Othello tells Desdemona that she is on her deathbed, he asks her if she has prayed that evening, which suggests that Othello believes Desdemona to be a sinner--he wants her to make herself right with the Lord before he ends her life.  Othello believes the ruse that Iago has set up throughout the play, and Othello thus refers to the supposed affair with Michael Cassio.  At first, Desdemona is not aware of the reason why Othello has claimed her to be false, but later he tells her directly that she must be murdered for having had an affair with Cassio.  Although Desdemona tells Othello the claim is false, Othello does not believe her and continues blaming her for being unfaithful.

How would you describe the four main characters in the short story "The Veldt"?

Lydia Hadley, the mother, is concerned that the automated house (namely, the nursery) is having a detrimental effect on the children. She is the first to suggest, to George, that they should have the nursery checked out by a psychologist. George is logical and marvels at the science behind the nursery. Lydia supposes it is real and is afraid of it. She runs when the lions chase them. George follows but, being logical, insists that the lions are illusions. She insists that they lock the nursery for a few days. She is genuinely afraid of the lions but she's also worried that the automated house has replaced them as parents. Eventually, George agrees that the nursery should be turned off because too much of anything isn't healthy. George and Lydia want the best for their children, but they have let the house and nursery be parent and playmate of the children for too long. George concludes: 

They're insufferable—let's admit it. They come and go when they like; they treat us as if we were offspring. They're spoiled and we're spoiled. 

Peter and Wendy are spoiled children. Peter is very intelligent and defiant. He does not hesitate to threaten his parents when they decide to lock the nursery. They are both fully addicted to the nursery and they get hysterical when George finally locks it up. The children show how diabolical they have become in trying to keep their nursery when the lock their parents in. The children have no significant feelings for their parents. They only love the nursery. One could blame them, but George and Lydia have not given them any discipline and this has allowed them to develop into defiant, spoiled brats. 

Discuss how Macbeth and Lady Macbeth's feelings are portrayed in Act 2 of the play Macbeth.

The first scene deals with Macbeth's thoughts as he ponders the terrible act he is about to perform. He has spoken to Banquo who told him that he had dreamt about the witches and Macbeth had asked him that they speak about them at an opportune time. Macbeth also informed Banquo that he will bring him great honour should Banquo support him. Banquo tells him that he will maintain his love and allegiance to his king, if he should be involved in any discussion. This implies that he might suspect that Macbeth is up to no good.

Once Banquo has gone to bed, Macbeth, in at the beginning of a soliloquy, mentions that he is waiting for the signal from Lady Macbeth to proceed to Duncan's chamber and murder him. It is at this point that he imagines seeing a dagger float in front of him. Macbeth is clearly in a terribly anxious state and the hallucination he sees is, to him, 'a dagger of the mind, a false creation proceeding from the heat oppressed brain.' He realizes that it is an optical illusion, but it becomes more defined for he then sees gobs of blood on its blade. He realises that it is the horror of the moment - the silence and the terrible act he is about to commit - that creates this ocular fantasy. He asks for the cobblestones in the courtyard to hide the sound of his footsteps in the eerie silence. He then states that as long as he is only a threat, Duncan remains alive, meaning that he has to kill him soon.

When the bell rings, he responds and mentions that once he goes, the deed will be done. He asks that Duncan not hear its sound because it is the last thing he will hear - the sound that signals his departure to either heaven or hell.

Scene two opens with Lady Macbeth's thoughts in which she expresses that she had done her part and that she was inspired by the drink that she had given Duncan's guards to make them drunk. she mentions the owl's cry which is a portent of Duncan's death Lady Macbeth has left the doors to his chamber open and she realizes that her husband is committing the heinous deed. She has also drugged the guards drinks which could even kill them - death or nature will determine if they survive.

The tense atmosphere leads to Lady Macbeth getting a fright when she hears her husband. She fears that the guards have awoken and that they had not been successful. She hopes that Macbeth had found the guard's daggers which she put at the ready and declares that she would have killed Duncan herself if he did not resemble her father so much.  

When Macbeth arrives he tells her that he had killed the king and anxiously asks her if she did not hear a noise. She says that she only heard the owl shriek and the crickets cry. The two are very tense and nervous. When Macbeth looks at his bloody hands he comments on what a sorry sight they are and Lady Macbeth quickly corrects him, saying that it is a foolish thought. Macbeth shows how truly distraught he is by mentioning that he could not say 'Amen' and that he had heard voices after killing Duncan. His wife seems to be more in control and tells him that he is acting cowardly.

Lady Macbeth tells him to wash the blood off his hands and asks why he had brought the guards' daggers with him and that he should return them. Macbeth refuses to go back and she offers to return the daggers and smear them with Duncan's blood to implicate them. Macbeth is obviously unnerved and when he hears knocking, he wishes that it could wake Duncan. He is clearly disgusted with himself for what he had done.

When Lennox and Macduff enter, Macbeth tells them at some point that it had been 'a rough night' - clearly an ironic statement. when Macduff discovers Duncan's bloodied corpse and cries out to awake everyone, Lady Macbeth acts the innocent and enquires what is causing the uproar. Macduff kindly tells her that it is not for her gentle ears to hear. Macbeth makes quite a speech about how wonderful Duncan was and that all that was important to him had ceased to exist, the moment Duncan died.

Macbeth then confesses that he had killed both of the guards out of anger and when Macduff wants to know why, he makes a speech about how he could not help himself to see the guilty guards lying there with Duncan's blood all over them. He suggests that no man who was loyal to Duncan could have resisted from lashing. He had slain them as a matter of honor and duty. To distract attention away from her husband, lady Macbeth seemingly faints and is carried away.

In The Crucible, what has happened in the town of Andover?

Salem and Andover were neighboring towns in Massachusetts, during the period of the infamous witch trials that are portrayed in The Crucible. Although the setting of the play is in Salem, the significance of Andover is that the people there revolted against the court, because they were tired of seeing so many of their townspeople falsely accused and hung. This rebellion was troubling news for the Salem judges, especially for Danforth. He and others feared that the people of Salem might be persuaded to follow those in Andover and throw over the court, thereby putting an end to the witch trials. More and more, the people in Salem were beginning to mistrust the court and blamed the witch trials for many of the bad things that were happening in the town. In Act 4, Reverend Hale returns to Salem with news of the revolt in Andover and he warns the officials that they too are courting a rebellion in Salem, by continuing to hold the witch trials which were based on lies and falsehood.

In the book Johnny Got His Gun, why does Joe like America?

Through flashbacks and soliloquies, Joe Bonham reflects on his life before, during, and after his involvement in World War I. In these flashbacks, we learn that Joe was an average boy living a pretty average life before he decided to join the military. He has memories of fishing with his best friend, when he first made love to his then-girlfriend, and even some tender moments of his mother's home-cooking.
These moments, alongside others, help us understand Joe as a patriotic young man who wants to join the military in order to serve his country. Here is where we first recognize his love for America.

Book 2 of the novel sees Joe recalling his experience in the war and how he is hit by an exploding shell, which causes him to lose his limbs. Here is when we begin to see his love for America wane.

However, it is much later in the novel where we finally see his love for America dissipate completely and become replaced with rage. When Joe is finally able to communicate with the nurses caring for him, he requests that he display his body for others to see so that they can see the ramifications of war and the pain that it causes; he wants his reality to serve as the reality of war versus the myths often propagated. Unfortunately, his request is denied and he is left to his silent anger as faceless military officials pin a military medal to him.

Why did Maniac Magee keep Amanda's book in Maniac Magee? (Ch 6-12)

Maniac is fascinated with Amanda’s book and keeps it to reread.

Amanda keeps her whole library in a suitcase.  Maniac is very impressed when he sees all of the books.  He asks Amanda to borrow a book, only one, even the shortest one.  When he asks for her address and promises to return it, she finally relents and tosses him a book because she is late for school.

The book came flapping like a wounded duck and fell at Jeffrey's feet. It was a story of the Children's Crusade. Jeffrey picked it up, and Amanda Beale was late to school for the only time in her life. (Ch. 3)

Jeffrey (Maniac) has to do everything with one hand now that he has the book.  This barely slows him down.  He shows up all of the other kids playing sports one-handed.  He is enamored with the book.  Even though he is able to read it quickly, he can’t bear to give it up.

He started reading Amanda Beale's book his second day in town and finished it that afternoon. Ordinarily, he would have returned it immediately, but he was so fascinated by the story of the Children's Crusade that he kept it and read it the next day. And the next. (Ch. 8)

Maniac has clearly missed the elements of normal life.  For him there has been no school, and no books.  He loves the story and rereads it passionately.  Maniac brings the book with him everywhere, and is able to keep it in perfect condition until Mars Bar attacks him and takes the book from him.

Maniac is horrified by Mars Bars’ defiling of the book.  A page rips out while the boys tussle over it, and he doesn’t want to return the book to Amanda in that condition. Maniac tells Amanda that it was Mars Bar’s fault.  She kicks Mars Bar for hurting her book.

Maniac is able to find a small amount of normalcy with Amanda.  Even though she is black and he is white, that means nothing to him.  He cares about Amanda, and the friendship is formed by her lending him a book.

Which one of the three tenets of Transcendentalism is the most stressed Ralph Waldo Emerson's essays "Self-Reliance" and "Nature"?

*The basic tenets of Transcendentalism are these three:

1. A firm belief that God is present in all aspects of Nature, including every human being (this is the concept of the Over-Soul)


2. A conviction that through the use of intuition everyone is capable of learning of God's existence 


3. The belief that all of Nature symbolizes the spirit, and the world is good

—(1) In "Nature," Emerson writes of nature wearing the colors of the spirit, adding that when a person is in communion with nature, he feels the presence of God. He writes that he becomes "a transparent eyeball." Emerson declares that he is part of God (the Over-Soul)

(2) I see all. The currents of the Universal Being circulate through me: I am part and particle of God.

*(3) Emerson writes, "Nature always wear the colors of the spirit."

*The tenet that is most stressed in "Nature" is this third one. Throughout the essay, Emerson expands upon the universality of God's presence in landscapes, sunsets, the woods, the wilderness, and the sky.

—In "Self-Reliance," Emerson exhorts people to trust themselves and be nonconformists.

*(1) Early in this essay, Emerson expresses his belief that the individual has an importance that is divine: "Accept the place the divine Providence has found for you...." This quote, too, stresses that the individual is connected to the Divine.

*This first tenet of Transcendentalism is the only one that is stressed in "Self-Reliance." This essay includes no allusions to nature; instead, it is solely about the importance of the individual and nonconformity: "Nothing is at last sacred but the integrity of your own mind."

What are the two prominent theories of government?

There are many different ways of categorizing theories of government, but if I had to name a single dichotomy between two fundamental concepts of government it would be between Hobbes and Rousseau. Both of these theories are based on the idea of a "state of nature" that existed before governments, perhaps conceived as the state that human beings lived in 200,000 years ago.

Thomas Hobbes held that the state of nature was one of constant violence and competition; life was "nasty, brutish, and short" as he put it. On his view, government exists to restrain our base animal instincts and keep us from lapsing into our innate tendency toward violence. Hobbes favored a very strong government; indeed, in Leviathan he basically argues for a government with absolute, unquestioned power.

Jean-Jacques Rousseau, on the other hand, argued that human beings are naturally cooperative, compassionate, and kind. On his view, government was created by tyrants imposing their will on others, and far from protecting us, government was actually the source of most violence in the world. He suggested doing away with government entirely, or failing that, establishing a very weak government with very strong guarantees of freedom and accountability. He had a strong influence on the French Revolution and its ideals of liberty and democracy.

Which one is true? In my opinion, both extremes capture part of a more complex truth. In the study of human evolution we find both innate capacities for compassion and altruism, as well as for violence and hatred. Government does serve a vital function in protecting us from crime and invasion, but it must also be kept in check, limited in power and always held accountable to the people it is meant to serve. Democracy is the attempt to strike this delicate balance, and as Winston Churchill famously said: "Democracy is the worst form of government, except for all those others that have been tried."

What is the central idea of "Stopping by Woods on a Snowy Evening?"

At the center of Robert Frost's poem is the description of a moment of contemplation -- how our daily activities, in all their complexity of decision and actions, the moments obfuscate the larger "meanings" of our actual physical existence.   The narrator here (we always assume "I" means Frost himself here) is near the end of a day of mundane, everyday activities, when the tranquility of the scene temporarily causes him to pause.  Even his horse, a creature of simple consciousness that is freed of the burden of self-consciousness, "thinks it queer" that they should stop here for no apparent reason (Frost purposely uses the word "thinks"), just as we, in our daily routines, do not stop to contemplate the present.  The poem, then, becomes a snapshot of our own (the reader's) failure to live in the moment. 

What is the "mix" in the US economy relative to most other countries' economies?

Your question is asking about mixed economies. The US is indeed a mixed economy, meaning a blend between a capitalist society and government-controlled economics. The US economy is capitalist in ideal but is still regulated by laws in regard to trade sales, and the government owns roads, utilities, and many other sectors.

There are a variety of mixed economies throughout the world. It is most common to find mixed economies. China for example was a state owned and thus not really mixed economy, but since the 1990s has been becoming progressively more mixed and open to capitalist enterprise. North Korea would be an example of a non-mixed economy. North Korea is an extreme example of socialism. The US draws on socialist notions in such things as welfare and state regulations on business, yet primarily the US is capitalist.

What are three ways Atticus is understanding throughout the novel To Kill a Mockingbird? How does the text support this?

Atticus is a moral, understanding character in the novel To Kill a Mockingbird. There are several scenes throughout the novel that display Atticus' understanding of his family and the community members of Maycomb County. In Chapter 9, Scout begins cursing, and Uncle Jack attempts to correct her. Atticus says,

"Bad language is a stage all children go through, and it dies with time when they learn they're not attracting attention." (Lee 116)

Atticus handles the situation calmly because he understands that Scout is going through a phase that will end soon.

Atticus displays his understanding of Maycomb's community members in Chapter 11. After Jem destroys Mrs. Dubose's camellia bush, Atticus says,

"Jem, she's old and ill. You can't hold her responsible for what she says and does. Of course, I'd rather she'd have said it to me than to either of you, but we can't always have our 'druthers." (Lee 140)

Instead of letting Jem off-the-hook, or yelling at him, Atticus explains the reason Mrs. Dubose said those hurtful comments. He understands that she is old and sick, and shows sympathy for her when others feel contempt. He tells Jem, "Whatever she says to you, it's your job not to let her make you mad." (Lee 133)

Another scene which portrays Atticus' ability to understand his community members is in Chapter 23. Atticus reacts calmly after Bob Ewell spits in his face. When Atticus comes home, he tells Jem,

"Jem, if you can stand inside Bob Ewell's shoes a minute. I destroyed his last shred of credibility at that trial, if he had any to begin with. The man had to have some kind of comeback, his kind always does." (Lee 292)

Atticus understands how Bob Ewell feels, and doesn't blame him for his reaction. One of the major themes throughout To Kill a Mockingbird deals with perspective and Atticus tries to teach his children to understand how others feel in various situations.

In Fitzgerald's The Great Gatsby, why is Daisy a static character?

A static character is one who shows no change or growth over the course of a story.  And this is utterly true of Daisy, whom we find to be a wealthy, irresponsible, and careless girl at the beginning of the story.  She is a material girl who chooses a mate of her own kind, Tom Buchanan.  She has no interest in any important matters in the world, going through her life drinking, dancing, and partying. Her response to learning she has given birth to a girl is to say, "'And I hope she'll be a fool - that's the best thing a girl can be in this world, a beautiful little fool'" (Fitzgerald 21). We see no change in her from the moment we are introduced to her through the entire story, to its very end.  She remains careless and irresponsible, and chooses once again, over Gatsby, Tom Buchanan, who is really her male counterpart. Even her running down Myrtle Wilson, a tragedy, and allowing someone else to take the blame does not change her in any way at all.  We leave Daisy as we found her, a static character. 

In Harper Lee's To Kill a Mockingbird, what evidence shows that Tom Robinson is innocent?

Chapters 17 and 18 are the sections in Harper Lee's novel To Kill a Mockingbird in which the physical evidence of Tom Robinson's innocence is revealed. The revelation concerning Tom's physical condition -- in effect, that his crippled left arm made it impossible for him to have inflicted the bruises on Mayella Ewell's face and similarly made it extremely unlikely that this destitute African American could have raped this large, healthy young woman. It is during Atticus Finch's questioning of Mayella during the trial that Tom's disability is revealed. In the following passage, Scout, the novel's young but observant narrator describes the defendant's condition:

"Tom Robinson’s powerful shoulders rippled under his thin shirt. He rose to his feet and stood with his right hand on the back of his chair. He looked oddly off balance, but it was not from the way he was standing. His left arm was fully twelve inches shorter than his right, and hung dead at his side. It ended in a small shriveled hand, and from as far away as the balcony I could see that it was no use to him."

The above passage is from Chapter 18 of Lee's novel. The preceding chapter is the one in which Atticus questions Mayella's father, the bitter and virulently racist 'white trash' who we are led to believe in Atticus' cross-examination is the one who is guilty of beating his daughter. It is in Chapter 17 that Atticus attempts to inject the notion of reasonable doubt into the jury's mind (despite knowing that Tom was doomed the minute he was accused of raping a white woman). The clever attorney, and conscience of this story, knows what the reader does not yet know -- that Tom's left arm is crippled. During his interrogation of Bob Ewell, Atticus asks the witness to sign his name, thereby displaying for the jury the fact that this ignorant, violent racist is left-handed, and so was the likely individual who struck Mayella. Scout provides her observation of her father's tactics in Chapter 17:

". . .Atticus was trying to show, it seemed to me, that Mr. Ewell could have beaten up Mayella. That much I could follow. If her right eye was blacked and she was beaten mostly on the right side of the face, it would tend to show that a left-handed person did it. Sherlock Holmes and Jem Finch would agree. But Tom Robinson could easily be left-handed, too."

It is early in the following chapter, 18, that the earlier passage describing Tom Robinson's disability is provided. It is the revelation of Tom's disability, combined with the reputation of Bob Ewell, that provides the greatest evidence of the former's innocence. That Tom would be convicted anyway, however, is simply a sign of the times depicted in Lee's novel. In the American South of the 1930s (as well as the centuries preceding that period and the decades that followed) simply being accused of raping a white woman was sufficient to ensure the African American male's conviction.

What are secondary materials as a source of law?

In legal research, one can use primary and secondary sources of law. Primary sources are statements of law from a court, legislature, or executive like a president or governor. These sources can include court decisions, the U.S. Code or Code of Federal Regulations, the text of legislative bills, laws, or statutes already on the books, or other legal documents such as contracts.

In contrast, secondary sources are supplemental materials which explain, discuss, analyze, and interpret the law. Examples of secondary law sources include legal news articles, law reviews, legal reference books such as encyclopedias or dictionaries, legal articles, or legal books. These secondary sources can range from a restatement or an extensive analysis of a particular primary source. Of particular importance is the fact that where primary sources have binding authority, secondary sources do not, even though they may serve to influence a primary source.

There are a number of secondary legal sources, each of which has specific functions. First, legal dictionaries provide definitions of legal words and legal-related Latin words and phrases. Black’s Law Dictionary is a popular secondary legal dictionary. Legal encyclopedias such as American Jurisprudence and Corpus Juris Secundum are another type of secondary source that provides broad commentary on a number of federal and state laws and are highly recommended as a starting point for subsequent research, particularly concerning unfamiliar legal areas. Third are legal periodicals which provide articles that may explain new topics, comment on the current state of laws, and provide in-depth analysis on particular cases or issues. Legal periodicals are typically law school journals, bar association journals, and trade newsletters. Fourth are annotated law reports which focus upon specific legal issues rather than the general points of law common to other secondary sources and usually contain case citations and references to other primary and secondary sources. The American Law Reports (ALR) published by Thomson/West is the most comprehensive set of law reports at the present time.

Additional secondary sources include legal treatises which provide very detailed explanations of particular areas of law; legal directories which enable a researcher to locate other legal information such as particular regulatory agencies, attorneys, professors, or other legal experts; loose-leaf services which provide up-to-the-minute coverage on rapidly-evolving and changing laws and statutes; and legal restatements which, as their name would indicate, restate some aspect of a law which may serve to further understanding by a researcher or provide guidance to subsequent court decisions on particular areas of the law.

Do you personally believe that you contribute to global warming?

I know that even though I'm conscious of my carbon footprint and try to minimize it, I contribute to carbon emissions that cause global warming and climate change. I don't think I've met anyone who doesn't.

Transportation is one way in which people contribute to global warming, and probably the biggest. I ride a bicycle to work and for errands and drive a fuel-efficient car when I do drive, but I'm still burning some fossil fuel. I also contribute to carbon emissions by using other forms of transportation such as flying. Products that I buy must be transported to the retailer, using fossil fuel and creating emissions. Some of the employees of the businesses I frequent arrive at work via fossil fuel transportation. Motor vehicle exhaust is the biggest source of greenhouse gases worldwide.

Electricity is also a source of carbons emissions, as some electricity in the U.S. is produced from burning coal. I live in an area that produces hydroelectricity, but the nature of the electrical grid is such that we all contribute to climate change by using electricity from the grid. In addition, electricity is needed to produce products that we all use.

In Tangerine, what is the name of the Lake Windsor soccer team?

The Lake Windsor Middle School soccer team is known as the Lake Windsor Seagulls.

It’s obvious that Tangerine author Edward Bloor had some fun with the school team names. The Tangerine Middle School War Eagles are a sharp contrast to the Lake Windsor Seagulls. While the Seagulls play soccer for fun, the War Eagles are vicious players who fight for every win. The Seagulls are “toe stubbers” who rely on their two best players to eke out wins against lesser schools. As far as team names go, the peaceful and nonthreatening nature of seagulls perfectly describes the Lake Windsor soccer team. The predatory and dominating nature of eagles perfectly fits the Tangerine Middle School team.

When Paul switches from being a Seagull to a War Eagle, he finally finds a place for his competitive nature. Though usually a peaceful person, Paul quickly exemplifies the take-no-prisoners attitude of the War Eagles. He is proud of earning the right to wear the War Eagle jersey.

What domestic and foreign problems existed when George Washington became president?

Let's start with foreign problems....by separating from Britain, America had broken away from her largest trade partner.  America had to reconcile enough to sign a trade agreement with Britain that would not be too punitive, as colonial industrial output was still quite low.  Also, Britain still controlled forts in the Northwest Territory around the Great Lakes and often armed natives to attack American settlements there.  The French Revolution severely changed the government of America's first ally and America could not help France in its ensuing war with Britain.  Spain controlled the mouth of the Mississippi River, thus lowering the value of Western lands.  Domestically, there was the issue of paying the former Continental Army as the American dollar was nearly worthless.  There were still arguments of states' rights and certain areas of the country such as the Northeast even voiced opinions in favor of secession.  There was even dissent in Washington's own Cabinet, as Jefferson and Hamilton ultimately would not get along.  

How does segregation help increase genetic diversity?

The law of segregation is a principle of Mendelian genetics. The law of segregation occurs during meiosis when gametes are formed. At this time, the alleles for each gene segregate from one another. As a result, each gamete contains only one allele per gene. Thus, the gametes are haploid. The gametes need to be haploid so the specie’s diploid number is maintained when the egg and sperm unite. As a result of the law of segregation, each diploid parent passes a random allele for each trait to his/her offspring during fertilization. Thus, segregation increases variation within a species.

The law of independent assortment followed the law of segregation. The law of independent assortment states that the alleles form each gene segregate independently from one another when gametes are made. It was later found that linked genes don’t always follow this law. Needless to say, the law of independent assortment also contributes to variation within a species.

How many moles of hydrogen will weigh 1 kg?

The atomic mass of hydrogen is 1 g/mole. To make up 1 kilogram or 1000 g of hydrogen element, 1000 moles of hydrogen is required. Each mole has a Avogadro's number of atoms or `6.023 xx 10^(23)`  atoms. Thus, 1 kg hydrogen element or 1000 moles of hydrogen have `6.023 xx 10^(26)` atoms (or 1000 times the Avogadro's number). 

Hydrogen gas, unlike hydrogen atom, is made up of 2 atoms of hydrogen. Molecules of hydrogen gas are represented as `H_2` .  The molecular mass of hydrogen gas is 2 g/mole. To make up for 1 kg hydrogen or 1000 gm of hydrogen gas, we need 500 moles of hydrogen gas. These many moles of hydrogen gas will have `3.011 xx 10^26` atoms (500 times the Avogadro's number of atoms). 

Hope this helps. 

How does a reader find the figurative language in a poem?

Figurative language is the use of figures of speech to be more persuasive or interesting in writing or speaking. Figurative language includes, but is not limited to, simile, metaphor, personification, allusion, oxymoron, alliteration and punning.

Shakespeare, of course, is widely regarded as the master of figurative language. One of his most famous plays, Romeo and Juliet, is often read by high school students who are tasked with the analysis of his figurative language. So, how does the reader find the figurative language?

In Shakespeare, it is pretty easy. Rather than saying something in a literal fashion, Shakespeare goes further and attempts to paint a picture with his words. Instead of simply saying that Juliet is beautiful when he first sees her in Act I, Scene 5, Romeo says,

O, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
As a rich jewel in an Ethiop’s ear—
Beauty too rich for use, for Earth too dear.

The middle lines comparing Juliet to a jewel is a simile because Shakespeare is comparing two completely different things to highlight the attributes of the first thing. Similes always use the words like or as in the comparison. Metaphors are like similes without using like or as. In the famous balcony scene Shakespeare again extols the beauty of Juliet, this time with a metaphor:

It is the East, and Juliet is the sun.
Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief
That thou, her maid, art far more fair than she.

In this passage Romeo compares Juliet to another bright object, this time the sun. Notice that like or as is not employed in this comparison. Shakespeare extends the metaphor by saying that the moon is jealous of Juliet because the girl is far more beautiful. The scene is played out at night which makes it even more significant that Juliet is, figuratively, shining.

Personification is when the poet gives human qualities to something that is not human. In the preceding passage, Shakespeare not only uses a metaphor but also personifies the sun as a killer and the moon as feeling the very human emotion of grief. Another famous example of personification in Romeo and Juliet comes at the beginning of Act II, Scene 3 when Friar Lawrence gives human qualities to the morning and darkness:

The gray-eyed morn smiles on the frowning night,
Check’ring the eastern clouds with streaks of light,
And fleckled darkness like a drunkard reels
From forth day’s path and Titan’s fiery wheels.

Here, the morning is said to smile on the night. In other words, it is dawn and the sun is rising. Because Shakespeare used very few props, and modern theater lighting had not yet been created, he often describes the setting with his words. Darkness is receding and is compared to a drunkard staggering away.

Allusion, a reference to something from history or literature, abounds in the plays of Shakespeare, and Romeo and Juliet is no exception. Two of the most common sources for allusion in literary works are the Bible and Greek and Roman mythology. Of course, because Romeo and Juliet is a play about lovers, Cupid is invoked in several passages. In referring to Rosaline, the woman he is infatuated with at the beginning of the play and who spurns his advances, Romeo says, in Act I, Scene 1, "She’ll not be hit with Cupid’s arrow." Again, as Romeo's group is on their way to the Capulet's party in Act I, Scene 4, Mercutio invokes the Roman god of love when he tells Romeo, "You are a lover. Borrow Cupid’s wings and soar with them above a common bound." 

An oxymoron is a figure of speech which uses contradictory terms, or words that are literally opposed to each other. A famous oxymoron is the term "jumbo shrimp." In his tirade about how he loves Rosaline, but she could care less about him, Romeo uses several oxymorons in Act I, Scene 1:

Why then, O brawling love, O loving hate,
O anything of nothing first create!
O heavy lightness, serious vanity,
Misshapen chaos of well-seeming forms,
Feather of lead, bright smoke, cold fire, sick health,
Still-waking sleep that is not what it is!

Obviously, love doesn't match hate and, likewise, cold and fire are opposites.

Alliteration, often used by poets and songwriters alike, is the repetition of consonant sounds, as in the famous tongue twisters "Peter Piper...," and "She sells seashells..." Shakespeare uses alliteration in the very first lines of Romeo and Juliet. In the prologue, the chorus says, "From forth the fatal lines of these two foes." Notice the repeating "F" sound.

Punning is one of the most fun and creative uses of figurative language. A pun is a form of word play that highlights the different meanings of words that sound alike. An excellent example of a pun appears in Act I, Scene 4 of Romeo and Juliet when Romeo, explaining why he won't dance when he gets to Capulet's party, says,

Not I, believe me. You have dancing shoes
With nimble soles. I have a soul of lead
So stakes me to the ground I cannot move.

Romeo plays on the words sole and soul. His shoes have soles but they are quite different from his soul, which, at this point in the play, is heavy because he is in love with Rosaline, who does not share his affection.

 

 


  

What is urine infection and does it have a cure?

Urine infections are very common and are easily cured by taking oral antibiotics. Urine infections, which are also called urinary tract infections, are usually caused by bacteria. The bacteria enter the urinary tract and begin to multiply. This causes inflammation and sometimes pain when passing urine. Very rarely, urinary tract infections can be caused by viruses or fungi, although these are also easily treated.

A urinary tract infection usually begins in the lower urinary tract (the urethra and bladder). If untreated it can spread into the kidneys (the upper urinary tract). An upper urinary tract infection may cause pain in the lower back.  

A culture can be performed on a urine sample to identify the type of organisms present. This can be used to guide treatment decisions.

In Romeo and Juliet, is it true or false that Romeo gets courage to proclaim his love from overhearing Juliet's balcony speech?

It is true that Romeo gains the courage to speak to Juliet as a result of overhearing what she is saying.  As she steps out onto the balcony, she is unable to see him.  There, she thinks through their recent meeting, and thinks through the ramifications of loving a Montague.  It is in this scene that we get famous lines like, "O Romeo, Romeo, wherefore art thou Romeo?" (Act 2, Scene 2, line 33).

After Juliet discourses on the problem of loving a Montague, Romeo asks himself, "Shall I hear more, or shall I speak at this?"  (line 37).  He ultimately decides to listen longer.  When she ends the next part of her soliloquy by saying that she would take Romeo, should he choose to forgo his name, Romeo feels emboldened by her speech.  At this point, he comes out of the shadows and addresses Juliet directly.

What was Brian's plan if he ever heard a plane engine roar overhead in Hatchet?

Brian plans to have a fire ready so that he can wave a burning limb at a plane if he hears it.

When Brian’s plane crashes in the Canadian wilderness, he is alone because the pilot is dead.  Brian has to use all of his skills and intelligence to survive on his own.  He needs to find a way to get food and shelter, but his next concern is rescue.

Brian is worried that he will not have a way to contact planes that fly over him.  He decides to use fire.

Initially he had thought of making a signal fire every day but he couldn't….  So while he was working he decided to have the fire ready and if he heard an engine, or even thought he heard a plane engine, he would run up with a burning limb and set off the signal fire. (Ch. 11)

Brian tries to figure out how to make a spear out of a stick and use it to fish.  He does find berries to eat, but that does not work out well.  He is mostly concerned about not being rescued.

Brian doesn’t have to wait long to hear a plane.  Brian hears a plane one day and desperately tries to get to his fire fast enough to contact it.

He had to get fire up on the bluff and signal them, get fire and smoke up. He put all of his life into his legs, jumped logs and moved through brush like a light ghost, swiveling and running, his lungs filling and blowing and now the sound was louder, coming in his direction. (Ch. 12)

The plane keeps going, and Brian is not able to make contact.  Brian is sure that it is a search plane.  He is devastated, convinced that they won’t come back and he will never be rescued.  He feels changed because “the disappointment cut him down.”  He makes a new fire that is smokier.

Eventually a plane does come and find Brian, the pilot telling him that he heard his emergency transmission and saw the crashed plane.  Brian is finally saved. His persistence has paid off.

How long have Faith and Goodman Brown been married?

Faith and Goodman Brown have not been married long.  The text says three months.  

What, my sweet, pretty wife, dost thou doubt me already, and we but three months married?"

Even without that direct textual evidence, the reader could probably figure out that Faith and Goodman Brown have not been married for very long.  First, the title of the story specifically tells readers that Goodman Brown is young.  The text also says that Faith is "his young wife." I assume that somebody who is young and married could not have been married for more than a few years.  

The opening paragraphs and dialogue between Goodman Brown and Faith give even further evidence that they are quite recent newlyweds.  

"Dearest heart," whispered she, softly and rather sadly, when her lips were close to his ear, "prithee put off your journey until sunrise and sleep in your own bed to-night.

That's a "come hither" line and the body language speaks volumes about her desire to be physically near her husband.  It's not that older married couples can't or don't feel this way about each other; it's just that part screams newlywed to me.  There are usually jokes surrounding newlyweds, because they can't keep their hands off of each other.  The above line hints at that kind of relationship.  

In The Outsiders, on what page can you find the word "scrap"?

I can't find the word "scrap" on any page. I opened a pdf copy of The Outsiders and I searched for the word "scrap." I found "scraped" on page 51, and "scraping" on page 91 and page 151.

The word "scrap" can mean a small piece, or a fight (or rumble).

I found a few instances where a piece of paper is mentioned. On page 41, Two-Bit tears up a piece of paper with Marcia's number on it. On page 70, Dally gives Ponyboy a piece of paper with a letter from Sodapop.

"Scrap" can also mean "fight" or "rumble." Ponyboy talks about fighting on pages four, ten, and 18, and Two-Bit discusses fighting with Cherry and Marcia on page 27. On pages 48 and 49, Ponyboy and Johnny get into a fight with Bob and the other socs. On page 107, Dally and the greasers start preparing for the rumble with the socs. On page 109, Two-bit and Ponyboy talk to Cherry about the upcoming rumble. The rumble starts on page 117.

I hope this helps. If you still want to find a specific word in The Outsiders, I suggest you purchase a pdf or other ebook version and use your search function on your computer or e-reader. Good luck!

In To Kill a Mockingbird, what is the significance of Mrs. Dubose's addiction to morphine, and why was she so irritable?

After Mrs. Dubose's death, Atticus stated that she was the bravest woman he ever knew. This utterly confused Jem because all he ever witnessed was how mean she had been. In fact, every single time he and Scout walked by her house, she would yell "philippics" at them:

"Don’t you contradict me!...And you—what are you doing in those overalls? You should be in a dress and camisole, young lady! You’ll grow up waiting on tables if somebody doesn’t change your ways—a Finch waiting on tables at the O.K. Café—hah!"

The last straw for Jem was when Mrs. Dubose insulted Atticus by saying that he was "in the courthouse lawing for niggers," and he was sent him in a fit of anger which ended with Jem destroying Mrs. Dubose's camellias. Jem's punishment was to read to Mrs. Dubose for an extended period of time. When he and Scout first entered her home, "she was lying under a pile of quilts and looked almost friendly." However, that amiability didn't last long before Mrs. Dubose called Scout "dirty."

During their time at her home, the children noticed that Mrs. Dubose would often have "fits" and then doze off. Usually an alarm clock would go off around this time. Over time, Mrs. Dubose stayed awake longer and longer and listened to more of Jem's reading. The day came when Atticus arrived to pick up the children, and Mrs. Dubose triumphantly exclaimed, "Do you
know what time it is, Atticus?...Exactly fourteen minutes past five. The
alarm clock’s set for five-thirty. I want you to know that." The significance of time was a mystery to the children.

Mrs. Dubose died about a month after Jem's "sentence" was over which was something Jem had conflicted feelings about. On one hand, Mrs. Dubose had been rotten to him and his sister. On the other, she had passed away. Atticus says to Jem that she was "not suffering any more. She was sick for a long time," and asks his son if he knew "what her fits were." It was then that Jem learned the truth about Mrs. Dubose and her nasty temper: She was a morphine addict. A doctor had prescribed the drug as a pain killer and she had gotten hooked. Jem's reading distracted her from the withdrawal. She could've died pain-free, but she chose to die without addiction. Atticus then handed Jem a perfect camellia in a box, a gift from the deceased and a sign that everything was now okay. She was at peace.

Jem now understood why Mrs. Dubose was so nasty: she was in pain and going through withdrawals. Choosing to die experiencing so much suffering especially when she didn't have to was certainly a very courageous feat.

Did Socrates imagine philosopher-kings to be rhetoricians or very eloquent?

The first thing to consider is that we do not know what Socrates as an historical figure thought about the issue, only what the Socrates character in various Platonic dialogues said as he took part in various discussions.

In general, Plato's dialogues are highly critical of rhetoric. Plato describes the sophist (ancient teacher of rhetoric) as one:

who, belonging to the conscious or dissembling section of the art of causing self-contradiction, is an imitator of appearance, and is [engaged in] the juggling of words

and who preys financially upon the young and innocent in Sophist. Gorgias, Protagoras, and Apology also include extremely negative treatments of rhetoric, and Phaedrus makes a strong distinction between philosophical discourse and rhetoric. Plato's Republic presents rhetoric, like poetry, as corrupting its audience.

Thus Plato and his Socratic character are both strongly opposed to rhetoric and eloquence and would not wish philosophers to be skilled at them. Instead, what Plato's Socrates recommends is precise use of language, which strives to educate rather than please and to discover truth rather than opinion. This distinction is present most clearly in Statesman and Sophist, although covered to a lesser degree in Republic. 

I need to identify important quotes from the poem "Huswifery."

Make me, O Lord, thy Spining Wheele compleate

I think the opening line of the poem is a critical line to the poem. It's a critical line because it identifies so many components of the poem's narration.  It identifies who the poem is addressing - God.  It identifies who God should help - Edward Taylor.  Lastly it identifies what Taylor wants done.  He wants to be the Lord's metaphorical spinning wheel.  The opening line is also important because it shows the reader that the poem is a prayer.  That might be considered useless to understanding the poem, but it is critical to understanding the speaker. The fact that the poem is a prayer shows readers that the speaker is religious in some way.  But for me, it is the final stanza that shows the speaker's religious passion as true instead of a faked faith to impress other people. 

. . . that their shine may fill

  My wayes with glory and thee glorify.

Taylor goes through the poem asking God to make him great, but the above line identifies the reason.  Taylor does not want to be made great for his own glory. He wants to be made great to reflect and shine back on God in order to glorify God more. That's  true faith.

How is the theme of censorship and mind control seen in Fahrenheit 451?

Though a reader’s first instinct may lead them to interpret Fahrenheit 451 through the lens of censorship, the ambiguous nature of Beatty’s character shows that Bradbury had a larger theme he was addressing than just indicting the lack of literacy in this dystopian society. Aware of a change in Montag, Beatty attempts to manipulate Montag’s opinion about what is contained in books through a rhetorically skillful speech to quell Montag’s rising curiosity. Beatty is a contradictory character in that he is aware of the knowledge found in books, but also advocates their eradication. To further subvert too much emphasis on censorship, Faber explains to Montag, “Remember, the firemen are rarely necessary. The public itself stopped reading of its own accord…so few want to be rebels anymore…people are having fun” (83). Published in the 1950s, Fahrenheit 451 is a reflection of America’s cultural climate and social norms including the prominence of complacency and conformity. Beatty’s ambiguous characterization serves to represent an aspect of Bradbury’s theme regarding his rejection of conformity as stressed by Montag’s media-saturated culture. Attempting to read on the train, Montag’s concentration is continuously disturbed by radio advertisements. Montag describes mass-media's influence by stating, “The train radio vomited upon Montag, in retaliation… [t]he people were pounded into submission; they did not run, there was no place to run…” (75). This statement not only illuminates the constant media inundation, but the latter half of his statement reveals, like Faber’s statement, society’s lack of concern and willingness to conform.

Bradbury isn’t simply making a statement against conformity, but rather condemns conformity that stems from ignorance. Montag joins the band of bibliophiles for a similar purpose and with the same goals. However, this is viewed as a positive conformity because, as their name implies, each is equipped with the knowledge of a book and their banded together through awareness, not ignorance. Bradbury supports this idea through the willing death of paradoxical Beatty. Even though Beatty attempts to use skillful rhetoric to influence Montag in continuing as the “Happiness Boys,” he is not an entirely unsympathetic character. After lighting him on fire, Montag turns Beatty’s words against him: “…you’re not a problem now. You always said don’t face a problem, burn it” (115). Like the bibliophiles, Beatty is also book learned, and similarly, his conformity doesn’t stem from ignorance. The difference between these two is analogous to Montag’s discovery that fire can both burn and warm. In this way, Beatty knows what he should do, but rather than face the problem of conformity, conforms himself to society. Seeing Montag’s willing resistance to conform, Beatty realizes his mistake, and dies a willing death to emphasize Bradbury’s rejection of conformity so prevalent in 1950s America.

What is a good clincher for an essay that is in favor of taking a year off before beginning college?

A topic that could, perhaps, be an attention-getter is one that mentions taking a year off before college as stepping out of the protected world of school into the harsh, real world before going to another controlled setting of the educational environment. Such a title could be Interim from Fantasy Land. Another title could be Climbing Down From the Ivory Tower. (The metaphor of "Ivory Tower" is used for educational institutions which are apart from the practical affairs of the real world.)

• Interim from Fantasy Land

According to Time magazine, studies show that students who take a year's hiatus between high school and college are more mature and more interested in their educations. For one thing, the academic break allows students to rest from such things as

AP classes, tutors, test prep, community-service projects, varsity sports, piano lessons and other extracurricular activities. 

While they are in this hiatus from academics, students often travel or work at a job or do volunteer work. In such instances, these students learn about others, what options are available to them, what fields they would like to enter, etc. These experiences, then, assist students in choosing a field in which they would like to major.

• Climbing Down From the Ivory Tower

When students take a year's hiatus, they can eliminate the worry of their choices and actions being recorded on their academic record; they can relax and enjoy their lives. If they work, students glean a realistic perspective on how much a person needs to earn to be comfortable and self-sufficient. They may also learn about others who differ from them and gain some political insights. Taking what is called a "gap-year" often provides experience in the real world.

How do Phillip and Timothy show courage in two ways?

The Cay is a tale of growth, change, and survival. It tells the story of Phillip Enright, a young boy and Timothy, an older, Caribbean sailor who are forced to survive after their ship is sunk during World War II. The two characters and a cat are forced to survive on a small island while waiting for rescue.

Both characters show courage in several ways as the story unfolds. Timothy shows courage by helping to rescue Phillip in the midst of the ship sinking. When Phillip eventually loses his eyesight (temporarily), Timothy shows courage by helping Phillip cope and become independent on their small island. Timothy shows the ultimate courage by the end of the story when he sacrifices his life in the hurricane to save Phillip.

Phillip is also able to show courage throughout the book. He is able to deal with the fact that his parents might have been lost in the sinking of the ship. He copes with the fact that he loses his eyesight and, with Timothy’s prompting, is able to climb a coconut tree, which is a challenge considering his lost vision. This proves to be the ultimate symbol of Phillip’s growing independence. Finally, Phillip shows true courage when he is forced to survive on the island alone following the hurricane.

What are some examples of figurative language in Roll of Thunder, Hear My Cry?

An example of figurative language in the first chapter of Roll of Thunder, Hear My Cry is "Before us the narrow, sun-splotched road wound like a lazy red serpent" (page numbers vary by edition). The author is comparing the winding, muddy road to a serpent in a simile (a comparison that uses "like" or "as"). Another example of figurative language is the description of L.T. Morrison in Chapter Two: "The man was a human tree in height, towering high above Papa's six feet two inches" (page numbers vary by edition). Using a metaphor, a comparison that does not use "like" or "as," the author compares Mr. Morrison  to a tree. In Chapter Three, the author uses an example of personification, another form of figurative language: "At first the rain had merely splotched the dust, which seemed to be rejoicing in its own resiliency and laughing at the heavy drops thudding against it" (page numbers vary by edition). In this example, the dust has human qualities, as it seems to be happily resisting the rain. Personification involves giving human qualities or emotions to inanimate objects--in this case, dust. 

The number of valence electrons in an atom determines its ........?

The number of valence electrons in an atom determines its chemical properties (such as reactivity). If the number of valence electrons is 0, it means that the outer shell of the atom is completely filled and hence it is an atom of a noble gas and hence will be non-reactive. If the number of valence electrons is small, say 1 or 2, then it is likely that the atom will lose them and become a cation. Such atoms (After becoming cations) participate in ionic bonds. If the number of valence electrons is close to 8, then atom will gain electrons and become an anion and participate in ionic bonds. In other scenarios, the atom will neither gain nor lose electrons, rather it will share them with other similar atoms and hence participate in covalent bond.

Hope this helps. 

I have packs of 100 balls that should all be white. Occasionally a randomly distributed black ball appears in the population and I want to be sure...

Suppose the probability of a randomly-selected ball being black is P.

We want it to be so that after 100 samples, the probability that no more than 1 of those samples is black is less than 5%.

So, what is the probability of having more than 1 be black? It's easier, actually, to ask for the probabilities of 0 black balls and 1 black ball, and then add those up and subtract from 1.

The probability of having 0 black balls in 100 samples is (where n C k is the combination function, the number of possible ways to arrange k things from a sample of n things):

(100 C 0) * (P)^0 * (1-P)^100
1 * 1 * (1-P)^100
(1-P)^100

The probability of having exactly 1 black ball in 100 samples is:
(100 C 1) * (P)^1 * (1-P)^99
100 * P * (1-P)^99

These two things must add up to more than 95%:

(1-P)^100 + 100 * P * (1-P)^99 > 0.95
(1-P)^99 * (100 P + 1 - P) > 0.95
(1-P)^99 * (1 + 99 P) < 0.95

Because we have both a linear and an exponential term for P, this equation does not have an analytic solution. But all hope is not lost!

We can solve it numerically; by finding the intersection on a graph I estimate the needed P to be about 0.0035.

Let's try it:

(1-0.0035)^99 * (1 + 99*0.0035) >? 0.95
0.7067 * 1.3465 >? 0.95
0.95157 > 0.95

Sure enough, that works.

If you want a more precise solution, you could try some nearby values such as 0.00351 and see how high you can get P before it tips over and actually drops below 95%. But since they asked in terms of "balls per thousand", 0.0035 seems to be precise enough; that's 3.5 balls per thousand.

Round down to 3 and we're all set: If we ensure there are no more than 3 black balls per thousand total balls, we can insure that there is a 95% chance of each 100-ball set containing no more than 1 black ball.

Describe Daniel bar Jamin from The Bronze Bow

Daniel bar Jamin is lonely and bitter.  Almost everyone in his family has died, both directly and indirectly, at the hands of the Romans.  He is taken into slavery, but is able to escape.  His hatred toward the Romans leads him to vow to avenge the deaths of his family.  Daniel becomes friends with Rosh, who is a rebel reader.  Rosh believes in using forceful means to achieve his goals, and Daniel's hateful heart agrees.  Then Daniel begins to hear the messages of Jesus.  Jesus teaches a message of peace.  This conflicts with the revenge Daniel yearns for.  He begins to reflect on the peaceful message of Jesus, as well as the healing and feeding of hungry people.  He contrasts these ideas and actions with those of Rosh, who he once admired.  Later, Jesus heals Daniel's sister, Leah.  She is the last surviving member of his family.  This causes the final change in Daniel's heart, and leads him to become a follower of Jesus.

In Romeo and Juliet, how is Romeo in conflict with himself?

Romeo particularly expresses self-conflict in act 1, scene 4 of Shakespeare's Romeo and Juliet.

In this scene, Benvolio and Mercutio are trying to persuade Romeo to crash the Capulets' ball with them, both for the sake of having fun at the Capulets' expense and because they know Rosaline will be there and hope Romeo will cheer up if he gets a glimpse of her. However, Romeo at first refuses, saying he feels far too gloomy to attempt to have a merry time.

Yet, despite his initial refusal, by the end of the scene, he has given in to the persuasion of his friends. Though, interestingly, Romeo now expresses that his hesitations are based on more reasons than just the fact that he feels sorrowful. Specifically, he informs his friends that he senses danger in going because he "dreamt a dream" last night (I.iv.52). By the end of the scene, we learn just how seriously he has taken his dream and interpreted it as an omen:

... my mind misgives
Some consequence yet hanging in the stars
Shall bitterly begin his fearful date
With this night's revels and expire the term
Of a despised life closed in my breast
By some vile forfeit of untimely death. (113-17)

In this passage, Romeo is asserting he has interpreted his dream to mean that interaction with the Capulets tonight will lead to his own untimely death.

Romeo's decision to cave in to his friends' persuasion and join them in crashing the ball represents a self-conflict within Romeo because his decision is based on conflicting desires. On the one hand, he rightly fears that going with his friends will lead to fatal consequences. On the other hand, he is young, full of energy, and cannot prevent himself from following in the footsteps of his friends in merry-making, his friends who are "lusty gentlemen" ready to lead the way, just like himself (119). Hence, Romeo's conflict represents a self vs. self conflict because his more rational nature is fighting against his instinctive, emotion-driven nature.

What did Sun Yat-sen do that still affects our lives today?

Sun Yat-Sen was the first President of the Republic of China, and he played a role in overthrowing the Qing, the last dynasty of China. He also founded the Nationalist Party, or Kuomintang, and he is often referred as the "father of modern China," as he put into effect policies and ideas that would mark the end of dynastic China and begin the process of modernizing China.

Educated partly in Honolulu, Hawaii, Sun was drawn to Christianity and later converted. Living in Hong Kong, he began to recruit followers to overthrow the Qing dynasty. He was in part motivated by his dislike of foreign control of China and Japan's defeat of China in the Sino-Japanese War of 1894-1895. He organized followers in Japan and returned to China in 1911, during a large-scale revolt against the Qing, to declare the founding of the Republic of China. He served as provisional President of the Republic, was later overthrown, and then came back as elected President in 1921.

He carried out several policies that affected China. First, he established ties with the Soviet Union to bolster his power and help bring about the reunification of China. In 1924, the Kuomintang established a constitution that followed the lines of the Soviet Union. Second, his "Three Principles of the People" established the importance of nationalism (or reuniting China under Chinese control), democracy (government based on a Western-style government), and a form of socialism (in which people's livelihood was protected by the government and the state owned many means of production). After Sun died in 1925, he as regarded as the "Father of the Republic." He also is regarded as the father of modern China, as he developed a nationalist agenda that involved ridding China of foreign control and reuniting the country. 

Concerning declarations of war, the A. power to declare war rests with the president only. B. National Security Council votes to declare war. C....

The answer to this question can be found in Clause 11 of Section 8 in Article I of the Constitution of the United States.  That clause says that one of the powers that Congress has is the power “to declare War.”  When the Constitution says that, it means that the Congress does not have to share that power with any other group or person.

The Framers of the Constitution did not want the president to have too much power.  They worried that a president who was too strong would become more like a king or tyrant.  Therefore, they did not give the president the power to declare war.  They wanted war to be declared only if there was strong support for war in the country.  For this reason, the Constitution gives Congress alone the power to declare war.

Critic Catherine Golden describes what happens to the narrator in "The Yellow Wallpaper" as a double palimpsest. What does she mean?

Charlotte Perkins Gillman's story "The Yellow Wallpaper" is an overlay of the story of so many repressed women during the Victorian era as it presents the medical and professional dominance of women as well as hegemonic masculinity. Also, in support of Golden's claim that the story is a double palimpsest, which is a manuscript that has been once written, effaced and written over anew; the story can be read as a chronicle of more than one aspect of sensory experience brought on by male repression.

• Medical/professional dominance and male hegemony

Gillman has the explicit purpose of exposing the oppressive forces of a male-dominated society and medical profession that was insensitive, as well as demeaning, to the unique nature of women. Dr. Mitchell's prescription for the narrator of complete "rest" devoid of any intellectual stimulation is peremptory and completely insensitive to her artistic nature. For, frequently the narrator mentions her pleasure in the various aspects of the garden that ignite her imagination--

...those mysterious deep-shaded arbors, the riotous old-fashioned flowers, and bushes and gnarly trees....I always fancy I see people walking in these numerous paths and arbors, but John has cautioned me not to give way to fancy in the least.

But, her pleasure is foiled by her physician husband's cautions that in her nervous and weak condition, she will have "all manner of excited fancies" if she gives in to her tendency to imagine things. 
The insensitive doctor and her husband keep her in a room that has unsymmetrical and ugly wallpaper with a "sub-pattern in a different shade," as well as furniture that is "no worse than inharmonious," while the floor has splintered wood with unsightly gouges taken from it "as if it had been through the wars."

In addition, her satisfaction in being able to write is also thwarted by the doctors,

I think sometimes that if I were only well enough to write a little it would relieve the press of ideas and rest me.

The narrator is also isolated as she is forbidden any companionship. She is promised the visit of relatives only after she becomes well as her physician husband declares that "stimulating people" would be detrimental to her.

• Multiple aspects of sensory experience brought on by the repression of such an artistic personality

Early in her confinement, the narrator begins to focus upon the unsightly wallpaper, noticing that it has "a kind of sub-pattern of a different shade." This lack of balance and aesthetic design, as well as the horrid color becomes very disturbing to the artistic narrator. In fact, she fixates upon this color so much that her experience of it breaks into two sensations, a perceptual anomaly termed synesthesia:

It is the strangest yellow, that wall-paper! It makes me think of all the yellow things I ever saw – not beautiful ones like buttercups, but old foul, bad yellow things. But there is something else about that paper – the smell! ... The only thing I can think of that it is like is the color of the paper! A yellow smell."

Further, the narrator begins to perceive a woman trapped behind the "bars" of the yellow wallpaper [yellow is a color of a certain malice or evil, corruption or decay]. And, thus, there is an experience of separation and duality in the narrator as this woman behind the bars becomes something like an alter-ego--"I wonder if they all come out of that wallpaper as I did?"--as well as a supernatural force to her:

"I've got a rope up here....If that woman does get out, and tries to get away, I can tie her!"

 Compelled, then, to free this woman, the narrator rips the paper: "I pulled and she shook."

Charlotte Perkins Gilman's story is an exposé of the mistreatment of women by both a medical profession and a patriarchal society. It also a chronicle of the multi-layered aspects of the artistic mind when it is repressed, as well as a Gothic tale of supernatural forces and the horrors of the mind. Indeed, "The Yellow Wallpaper" is a narrator's double palimpsest.

On STA, the assessment is based on scores in the Final Exam(X), Learn based on-line assessment (Y) and Assignments (Z). The 3 variables X, Y and Z are independent.

It is known from past experience that E(X) = 61, sd(X) = 20, E(Y) = 72, sd(Y) = 22, E(Z) = 65 and sd(Z) = 24.

The total marks are derived from X, Y and Z using the formula T = 0.5*X + 0.3*Y + 0.2*Z

E(T) = 0.5*E(X) + 0.3*E(Y) + 0.2*E(Z)

= 0.5*61 + 0.3*72 + 0.2*65

= 65.1

Var(T) = 0.5*Var(X) + 0.3*Var(Y) + 0.2*Var(Z)

= 0.5*20^2 + 0.3*22^2 + 0.2*24^2

= 460.4

sd(T) = 21.457

If the marks require to pass is 50%, to determine the probability that a randomly selected student will pass, first find the z-score.

z = (50 - 65.1)/21.457

= -0.7037

Using the normal distribution table, the cumulative probability of a score less than 50% is 0.24080 or 24.08%

The z-score corresponding to 90% is (90 - 65.1)/21.457 = 1.16046

This gives the probability of students getting 90% and above as 1 - 0.87707 = 12.293%

As there are 610 students, the number of students getting an A+ is 75.

What principles did Chief Justice John Marshall set?

There were several principles established by the Marshall Court. One of these principles is the concept of judicial review. This means that the courts can rule on the constitutionality of actions by the legislative branch and the executive branch. This ruling came out of a court case called Marbury v Madison. In the case, Marbury sued because his judicial appointment wasn’t finalized before Jefferson became President. When he wasn’t allowed to become a judge, he sued. In this case, the Supreme Court ruled that the constitution is the supreme law of the land and that the courts have the power of judicial review.

Another principle established by John Marshall was that a loose view of the constitution is legal. In the case of McCulloch v Maryland, the state of Maryland tried to tax the federal bank. The Supreme Court ruled that a state couldn’t tax a federal institution. It also ruled that a loose view of the constitution is acceptable.

A third principle established by John Marshall came in the case of Gibbons v Ogden. In this case, the Supreme Court ruled that the federal government could regulate trade between the states, called interstate trade.

These are three very important principles established by the Marshall Court. They have had broad implications on American society and life.

Where in The Great Gatsby are the lines, “He and this Wolfshiem bought up a lot of side-street drug-stores here and in Chicago and sold grain...

In my version of the book, the quote comes on page 143 of 193. The quote comes from Tom during an argument he is having with Gatsby and Daisy when Gatsby is trying to convince Daisy to run away with him. There is a fantastic moment when Tom accuses Gatsby of being a bootlegger but then goes on to claim that there is something else far more serious going on.

Nick describes the way that Gatsby looked. He notes that there is this odd look on Gatsby's face that quickly suggests something awful. He even goes so far as to say that it appears that Gatsby had "killed a man." 

Whatever it implied, it was sufficient to drive Daisy away again and ruin any hope that Gatsby had of her running away with him. Whatever it was that Tom found scared her back into the supposed safety of their world.

Of Man's First Disobedience and the FruitOf that Forbidden Tree, whose mortal tasteBrought Death into the World,and all our woe.." What is an...

John Milton opens Paradise Lost with "The Argument," a short summary of the Book; these lines describe Man's fall into sin after Eve and Adam eat from the Tree of Forbidden Fruit. Their having eaten from this tree has caused death and sin to come into the world, and "Man" is cast out of the Garden of Eden to have to struggle for existence. 

These lines which begin the first book of Paradise Lost allude to man's sin of disobedience in the Garden of Eden when Eve first ate from the tree that God forbade them to eat its fruit. In the first line "Fruit" is a pun upon the apple that Eve and Adam eat and the figurative "fruits" of their actions. After Adam and Eve are driven from Eden, it is not until "one greater Man," Jesus Christ, comes that mankind is "restored."

Paradise Lost addresses the question of how man [humanity] can endure in a fallen world, and it justifies the ways of God to Man. The first Book proposes the entire subject of Milton's renowned Poem written in English Heroic Verse without rhyme. This Book touches upon the cause of the Fall (as the lines above exemplify), Satan in the form of the Serpent who tempts Eve as he is "Stirr'd up with Envy and Revenge," Satan's revolt from God, and his having been driven from Heaven with all the others. Interestingly, in the European cultures, it is rather often that many people's beliefs in the history of Creation and Satan's existence derive from Paradise Lost and are confused with passages from the Bible.

Why are George and Lennie different from other guys who work on ranches?

George and Lennie are like the other men in every way, except in one very significant way. They are friends. In Steinbeck's book, one of the most significant and tragic points is that there are no friendships.  This is why Slim is so surprised that George and Lennie travel together. Here is what Slim says:

“Ain’t many guys travel around together,” he mused. “I don’t know why. Maybe ever’body in the whole damn world is scared of each other.”

Hence, George and Lennie's friendship is what sets them apart, and the men know this. Listen to what George says to Lennie, who listens in agreement. 

Guys like us, that work on ranches, are the loneliest guys in the world. They got no family. They don’t belong no place. . . . With us it ain’t like that. We got a future. We got somebody to talk to that gives a damn about us.

Even at the end of the book, George is a faithful friend.  We might not agree with what he did, but what motivated George's decision is his love for Lennie.  George believed that that men would harm Lennie and kill him in a far worse manner than if he shot him.  So, George's loyalty to Lennie made him take his life. 

what shows that the Watsons are not well off financially ?

There are many clues in The Watsons Go to Birmingham--1963 that show that the Watsons are not wealthy. At the beginning of the book, the entire family is shivering in the cold because their furnace is not working properly. The furnace sounds "like it [is] about to blow up." As a result, the entire family packs into their outdated 1948 Plymouth, called the Brown Bomber. A family that had more financial means might be able to buy a newer car, as the story takes place in 1963.

In addition, it's clear that they have to be very careful about not misplacing their clothing. Their mother buys them two pairs of gloves each winter, and if they lose the first pair, they have to wear the second pair pinned to their coats so that they won't misplace their gloves. The family also has to sign for their groceries at Mr. Mitchell's store in Chapter 6. Although Momma tells the children that they are no longer on welfare (though they had been in the past), she says that they can only pay for their groceries on payday. In other words, they don't have a lot of extra money at their disposal.

Even as they head south to Birmingham, it is clear that money is a worry to the family. For example, in Chapter 8, the father buys a new record player, but the mother is very worried about the expense. All of these clues show that the Watsons struggle financially.

In The Tale of Despereaux, what flaw does Miggery Sow see in Chiaroscuro's plan for revenge?

A line in chapter 36 sums up Mig's reaction to the ill-conceived plan that the rat presented to her. "But Miggery Sow, as I pointed out to you before, was not the sharpest knife in the drawer." 

This fact about Miggery's intelligence is stated time and time again, somewhat rudely, over the course of The Tale of Despereaux. When Roscuro tells Miggery his plan to make her the princess instead of Pea, the poor serving girl fails to see the obvious ridiculousness of his proposal. Sadly, at this point Mig doesn't see any flaws in the rat's plan, which he never clarifies is revenge until it is far too late. After the two of them have already taken Princess Pea into the dungeon, Roscuro orders Mig to chain up the princess. Mig argues that the princess is going have difficulty "learning her lessons" if she is chained up, but the rat is insistent that she obey him.

Mig's realization that the rat has no intention of honoring his promise to her comes far too late and the reader is left wondering how on earth she could have been so clueless. However, there are some very important reasons why Mig went along with such an idiotic scheme. It is stated very early on in Mig's story that her mother died when she was six and that she was sold as a slave by her father soon after. Mig, who was twelve when she met Roscuro, had been abused and treated with extreme cruelty nearly her whole life. Considering her tragic upbringing, her intelligence and understanding of the world was never properly allowed to develop. On top of that, the abuse she received was frequently delivered to her ears, meaning that there is every possibility that her head was hit on numerous occasions and she may have suffered brain damage. 

In the end, though, perhaps the most likely reason that Miggery would so blindly follow a rat with such a lackluster plan is that she desperately wanted to be a princess and live a good life. Roscuro was one of the only people in her life to ever show her compassion or an ounce of respect (even though he was only pretending) and she trusted him instantly to give her the happy ending she so dearly craved. 

1. Compare and contrast the list of grievances in the American Declaration of Independence with the list of grievances in the Vietnamese...

On September 2, 1945, Ho Chi Minh proclaimed the independent Democratic Republic of Vietnam in Hanoi. He did so in a manner that deliberately referenced the American and French declarations of independence. In fact, the opening sequence is spoken verbatim from the American Declaration of Independence. This was done with the purpose of demonstrating the hypocrisy of the west in that the French and United States feel that liberties should only be reserved for 'civilized' nations, or, at least, nations that are not communist.

Ho Chi Minh also wanted to communicate his grievances in the same way Thomas Jefferson did. For this reason, there are similarities in the grievances of the Vietnamese towards the French imperialist policies and America's grievances with England. Both declarations speak of unjust laws that are passed onto the colonies without the consent of the governed. Ho Chi Minh discusses how his people are exploited for economic gain in much the same way that Thomas Jefferson does. Both patriots reference the nature of taxation and how it has crippled the economies of their people.

A major difference between the two declarations is that the unfair practices of the French seem to greatly outweigh those of the British. This can be demonstrated in the charge of forcing the Vietnamese to consume alcohol and partake in the use of opium. Ho Chi Minh also mentions the slaughter of citizens by the French, a clear human rights violation that was not mentioned in the American Declaration of Independence. The Vietnamese leader also discusses the recent history of two imperial powers that have colonized Vietnam (France and Japan), while the American colonists were only ruled by one oppressor. Ho Chi Minh also discusses the cultural attack that the French orchestrated on his people. The American colonists were culturally identical to the British.

Any group of people that are unified and armed can impose war as evidenced by the decades-long Vietnamese struggle against France and the United States. Waging peace is more difficult as it requires a decisive military victory over your oppressor.
