Ten coulombs of charge start from the negative terminal of a battery, flow through the battery and then leave the positive terminal through a wire, flow through a resistor, and then return to the starting point on this closed circuit. In this complete process, the ten coulombs:
a. receive heat energy from the resistor.
b. do positive work on the battery.
c. have a net loss of potential energy.
d. have no net change in potential energy.
Question 2
A 40-kg boy is standing on the edge of a stationary 30-kg circular platform that is free to rotate. The boy tries to walk around the platform in a counterclockwise direction. As he does:
a. the platform doesn't rotate.
b. the platform rotates in a clockwise direction just fast enough so that the boy remains stationary relative to the ground. c. the platform rotates in a clockwise direction while the boy goes around in a counterclockwise direction relative to the ground. d. both go around with equal angular velocities but in opposite directions.
