1) What is the expected value for total work in each part of the experiment? 2) Why is the total work done so different between parts 1 and 2? 3) Is work necessarily a positive quantity? 4) If you drag a heavy box across a rough floor; is the work done on the box, in dragging it from point A to point B, independent of the path taken? Explain your answer. 5) The force on an object is non-zero. Over some path, the work, done on the object is zero. Is it possible that the object has moved in a straight line? Explain you answer.

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
