1. Reagan and Gorbachev are both credited as the leaders responsible for ending the Cold War. Reagan, unlike other presidents, wanted to destroy communism where possible rather than contain it. Gorbachev was also unlike other Soviet leaders. Gorbachev loosened the Soviet control of the masses allowing them more economic and political freedom. 2. The Soviet Union did not produce products for the people,and the people were not productive workers because they loathed working for the Soviets. 3. The policy of Glasnost was the Soviet policy of openness and transparency in the government brought forth by Gorbachev. 4. The Reagan doctrine put an end to the policy of containment by, as previously stated, attempting to destroy communism where possible rather than contain communism. 5. The concept of M.A.D. was that neither country would launch a nuclear attack on the other because both countries would be destroyed by the other. 6. The Soviet Union had brought the arms race to a halt after being unable to keep up with the United States defense spending. 7. Gorbachev and Reagan were unable to come to an agreement because Reagan refused to give up the SDI. The Soviets were afraid of the SDI because they did not know how to recreate this or even afford it. 8. The treaty which is considered to have ended the Cold War was the INF Treaty which eliminated intermediate-range nuclear missiles. 9. The fall of the Berlin Wall was the symbolic end of the Cold War. It represented the reunification of Germany, the end of Soviet rule, and the end of the Cold War. 10. After the collapse of the Soviet Union the quality of life did not get better. The inflation, lack of food, and overall poverty affected nearly everyone.

1. an object is moving to the right in a straight line. the net force acting on the object is also directed to the right, but the magnitude of the force is decreasing with time. how will the motion of the object change? a. it will continue to move to the right, its speed increasing with time. b. it will stop and then begin moving to the left. c. it will continue to move to the right at a constant speed. d. it will continue to move to the right, its speed decreasing with time. 2. a glass table top is able to exert a maximum normal force of 1600

Step-by-step answer

1. I am definitely sure that correct option is: a. It will continue to move to the right, its speed increasing with time. If the object is experiencing a net force to the right, it always accelerates to the right => the velocity is increasing, because the greater the force, the larger the acceleration.

2. In my opinion the answer should be b. The table top will break and the object will fall to the floor. We should count the normal force of the object. According to the conditions, we can use N=mg; N=165*9,8 = 1617 N. 1617 > 1600. That's why I've picked this option.

3. It's tricky question, because the weight of the rock depends only on the force of gravity. Speed doesn't affect the weight of the object. So it doesn't matter what the acceleration is, its force will be 138 N. So the answer is D.

4. The friction doesn't matter. We should use Newton's laws to define the normal force that the floor exerts on the chair.
So the solution is:
m*g + 80*sin(35)

; where

;
so the most approximate answer is B. 340 N.

5. I am pretty sure that correct answer is: b. extremely small values, such as the distances between particles in an atomic nucleus. According to its definition, strong interaction is a mechanism that is responsible responsible for the acts between subatomic particles of matter.

6. As far as I remember the correct option is: a. The action force and the reaction force act on different objects. Action and reaction forces are very important forces of a single interaction and they are not exist without each other. They're both equal in strength but opposite in direction.

7. I am not completely sure, but I think that the answer should be 48 N. We have normal force which is equal to the box's weight, so n = 320 N. Then we can count force of friction using the formula f = n*μ where μ = 0.15.
f = 320*0.15;

The answer is B.

8. -

9. We have $F_{ \alpha} = 330 N$ and $\alpha = 42$ . And this is all we need to find the real force that pulls the wagon forward.
The formula is:
$F_{f}=F_{\alpha}*cos( \alpha)$ ;
$F_{f}=330*cos(42)=244,2$ ;

So the most approximate answer is C. 245 N.

10. According to the free-body diagram given above, the answer should be d. a woman jumping off the floor. Because in this option the object is experiencing a vertical acceleration, and this means that the normal force acting on the object will not be equal to the weight of the object.

11. According to the Newton's second law of motion F=ma = a=f/m.

So the answer is A. 8 m/s^2
