Conclude a brief analysis as to whether you believe the fall of the Soviet Union was an inevitable occurrence, or could earlier Soviet leaders have...

If you believe the ideas contained in George Keenan’s Long Telegram, you would conclude that the fall of the Soviet Union was inevitable. The Long Telegram, about 8,000 words in length, stated that communism was a flawed system that would eventually fail. It suggested we would prevail over the Soviet Union without having to go to war. It suggested that our struggle with the Soviet Union was going to be one that would last for quite some time. Therefore, negotiations with them for a permanent solution were fruitless. Keenan pointed out that we should try to keep Communism from spreading. This became the basis for the policy of containment we used after World War II ended.

The only way the Soviet Union could have prevented its demise was to change its system. This was something the Soviet leaders were unwilling to do until it began clear their system was failing. Mikhail Gorbachev instituted a series of reforms and provided more openness in Soviet society. Even when it was clear these changes were the only way to possibly save the Soviet Union, hard-liner communists still were against these changes. Thus, the collapse of the Soviet Union was inevitable, even though it would take 45 years for that took occur after the Long Telegram was written.

`-165^@` Find the exact values of the sine, cosine, and tangent of the angle.

`-165^@=-(120^@+45^@)` 

`sin(-165)=-sin(165)`

`sin(u+v)=sin(u)cos(v)+cos(u)sin(v)`

`[sin(-(u+v))]=-[sin(u)cos(v)+cos(u)sin(v)]`

`[sin(-(120+45))]=-[sin(120)cos(45)+cos(120)sin(45)]`

`[sin(-(120+45))]=-[(sqrt3/2)(sqrt2/2)+(-1/2)(sqrt2/2)]=-sqrt2/4(sqrt3+1)`

`cos(-165)=cos(165)`

`cos(u+v)=cos(u)cos(v)-sin(u)sin(v)`

`cos(-(u+v))=cos(u)cos(v)-sin(u)sin(v)`

`cos(-(120+45))=cos(120)cos(45)-sin(120)sin(45)`

`cos(-(120+45))=(-1/2)(sqrt2/2)-(sqrt3/2)(sqrt2/2)=-sqrt2/4(1+sqrt3)`

`tan(-165)=-tan(165)`

`tan(u+v)=(tan(u)+tan(v))/(1-tan(u)tan(v))`

`-tan(u+v)=-[(tan(u)+tan(v))/(1-tan(u)tan(v))]`

`-tan(120+45)=-[(tan(120)+tan(45))/(1-tan(120)tan(45))]=-[(-sqrt3+1)/(1-(-sqrt3)(1))]=(sqrt3-1)/(1+sqrt3)`

After rationalizing the denominator the answer is `2-sqrt3.`

In the short story "Through the Tunnel," what is the author suggesting about the process of maturation?

Doris Lessing, the author of "Through the Tunnel," seems to be suggesting that the process of maturation is not a linear one. As we grow up, we don't neatly proceed from one step to the next in an orderly fashion, eventually ending up at the goal after we've taken each step in order and only once. The process of maturing is a great deal messier than that; the path is twisted and winding, sometimes turning back on itself for a time.

To begin, Jerry seriously desires some independence from his watchful and protective mother, and he longs to go to the "wild bay" to begin to achieve this. When he eventually does get there, he comes across some "big boys -- men to Jerry," and his desire to be accepted as one of them, a man, overwhelms him. Later, however, rejected by them, he "cried openly, fists in his eyes" and "he cried himself out," as a child would.

He has realized that he needs goggles in order to attempt the feat that those boys did -- swimming through the tunnel in the rock -- and he assaults his mother, unable to delay gratification (the ability to do this signals maturity), "defiant and beseeching" because he needs them "now, now, now! He must have them this minute and no other time." This is very childlike behavior.

As he practices holding his breath, day after day, "that other beach [...] seemed a place for small children [...]. It was not his beach." Jerry is beginning to have a sense of the patience one must exhibit in order to achieve something substantial. When he decides to go to the wild bay that day, "He did not ask for permission [...]." Adults do not ask permission; children do. Moreover, although he now believes that he could probably make it through the tunnel, "A curious, most unchildlike persistence, a controlled impatience, made him wait." He is acquiring the ability to delay gratification, a sign of his growing maturity and waning childish impulsiveness.

However, in achieving his goal of swimming through the tunnel he had been extremely frightened by it, and "He could see the local boys diving and playing half a mile away. He did not want them" anymore. Fitting in with those "big boys" had once been his primary goal, but it no longer appeals to him. Jerry, perhaps, has realized that he is not quite ready to be a man yet. In the end, he calls his mother "Mummy," a quite childlike way to address her, and blurts out that he can stay underwater for three minutes now. "It came bursting out of him," like a child would speak when seeking his mother's approval. It is now no longer the boys' approval he desires; he doesn't need their recognition as a fellow man. He is content, for now, to remain a child and accept his mother's praise and instruction without a "battle of wills."

This back-and-forth movement -- desiring independence one minute, displaying an inability to delay gratification the next, using patience and level-headedness to make a mature decision, and then reverting to childish tendencies and behaviors -- shows that the process of maturing is not a straight path from point A to point B. Instead, in this process, we often take two steps forward and one step back.

Who dies, and what happens at the burial at the end of the Death of a Salesman?

At the end of Death of a Salesman, Willy Loman, the main character throughout the story, commits suicide in an automobile accident and dies. Willy commits this act to allow his family to cash in on his 20,000 dollar life insurance policy so that his son Biff can get the money he needs to start his own business. Willy hopes that many people will attend the funeral, and Biff will see that Willy was actually someone popular and worth while knowing, and that this will cause Biff to realize that Willy was an important and successful salesman despite the fact that Biff caught his father cheating on his mother during a flashback earlier in the story. Sadly, only close family and friends attend the funeral, and the story ends with the family and their neighbors, Bernard and Charlie, standing at Willy's grave. During this scene, Biff tells the family he plans to leave town, while Happy, Willy's other son, tells everyone he will stay in New York and pursue Willy's dream of making a successful living in sales. The narrative ends with Willy's wife Linda pleading and asking why Willy would do this. Ironically, she confesses to paying off their house in full, a house that is now empty, with the insurance money from Willy's death.

Hope this helps!

What do each of the main figures in the cartoon represent ? What are they doing ?

The political cartoon, "Interrupting the Ceremony," appeared in the Chicago Tribune and is a critique on Woodrow Wilson's desire to have the United States enter the League of Nations. The League of Nations is depicted as the justice of the peace or preacher. He is attempting to wed Uncle Sam and a bride named "foreign entanglement." He is finishing the ceremony with the mandated "speak now or forever hold your peace."

The groom is good ole' Uncle Sam. He always represents the United States in political cartoons. His reluctance to marry foreign entanglements is depicted by a bead of sweat rolling down his forehead and the look of misery portrayed in his frown. The bride is foreign entanglements. "Foreign entanglements" is the idea that by entering the League of Nations, the United States would be constantly embroiled in the affairs and conflicts of other states. She seems to be perfectly content with this union.

The most important actor in this cartoon is the old grandfather bursting through the church window. He is symbolised as the U.S. Senate, who by Constitutional right, would have to bless this union. As indicated by his jumping through glass with the U.S. Constitution in hand, the Senate obviously has serious objections. History tells us that the Senate arrived in a nick of time to stop this marriage.

Summarize chapters 6 and 7 of the novel Lord of the Flies.

Chapter 6 "Beast from Air": The chapter begins with the descent of a dead paratrooper from the sky after he is shot during an air battle that takes place over the island while the boys are sleeping. His parachute gets tangled in the canopy of the forest and his lifeless body rocks back and forth when the wind blows. When Samneric awake, they see the dead paratrooper and mistake him for the "beast." After Samneric tell Ralph about the sighting, Ralph calls for an assembly where a search party is organized. The boys, armed with spears, travel up the mountain in search of the beast while Piggy and the littluns remain at the base camp. As the boys explore the island they come to an unknown area, where Ralph volunteers to lead the way. The area where Ralph explores will become Jack's base camp later on in the novel, and the boys begin to play in the caves and roll rocks down the side of the hill at this new location. Ralph notices that the signal fire has gone out and reprimands the boys for playing and rolling rocks down the side of the hill. Jack comments that they should stay there and build a fort. Ralph speaks up and reminds the boys the purpose of their expedition. The majority of the boys want to either stay at the "Castle Rock" location or go back to base camp, but Ralph insists they continue up the mountain.

Chapter 7 "Shadows and Tall Trees": At the beginning of the chapter, Ralph notices that his hair has become long, and his body is filthy. Ralph laments at his appearance and realizes that it has become the norm on the island. Simon comforts Ralph by saying, "You'll get back all right. I think so anyway." (Golding 111) Ralph is comforted by Simon's comments, but believes he is "batty." Roger mentions that he's spotted fresh pig feces, and the group decides to hunt a boar. They eventually spot the boar, and it breaks through the forest towards the boys. Ralph manages to wound the boar on the nose, but the pig continues to run and injures Jack before getting away. The boys remain in a frenzy and begin to enact the hunting scene with Robert playing the "pig." The game gets out of hand, and Jack suggests that they use a littlun as a pig the next time they partake in a reenactment. The sun is setting, and the boys discuss whether or not to continue up the mountain or return to base camp. Simon volunteers to go back to the base camp and tell Piggy their location. Simon travels by himself through the forest alone. Ralph, Jack, and Roger begin to climb to the top of the mountain as the sun goes down. Ralph and Roger refuse to climb to the summit, and Jack chastises them for being cowards. Jack continues and sees what he thinks is the "beast," then runs down to tell Ralph and Roger what he saw. The three travel as a group to the summit and view what looks like a great ape with its head between its knees. They freak out and run down the mountain in terror.

What are the products of the following reaction? Zr(NO3)4*5H2O + CH3CO2H =?

The first compound you have listed is zirconium nitrate, which is a crystalline solid, but is soluble in water.  The second compound, after water, is acetic acid.  So we basically have a nitrate compound being combined with an acid.  Acids are substances that offer H+ (hydrogen ions) when combined with water, so what happens is the hydrogen ion separates from the acetic acid and displaces the zirconium ion.  The products formed are nitric acid and zirconium acetate.

Zr(NO3)4 times H2O  +  CH3CO2H ----->  HNO3  +  Zr(CH3CO2)4

When you mix a nitrate with an acid, as in this chemical reaction, there is the extreme likelihood of an explosion, a fire, or something of a similar catastrophic nature.  This is an exothermic reaction, meaning the products will have less energy than the reactants.  The difference in energy is given off in ambient heat energy.  This can result in pressure being generated, an explosion taking place, or at the very least, an appreciable difference of temperature being given off.  Care should be taken, appropriate eye care and clothing protection should be exercised.  Toxic vapors may also be a concern, a well ventilated area should be considered for this reaction.
