If the nation's yearly total energy use and also the yearly gross national product [GNP] are graphed, the two graphs rise at the same rate until the mid-1970s, but they diverge from each other after about 1973
This divergence of the graphs shows that
A) energy use increases when the nation's goods and services increase.
B) U.S. energy efficiency decreased after 1973, due to lower energy prices.
C) energy efficiency has played a large role in providing goods and services since 1973.
D) as the price of goods and services decreases, energy use increases.
E) an increasing GNP causes energy use to also increase.

Two cylinders made of the same material roll down a plane inclined at an angle ? with the horizontal. Each travels the same distance. The radius of cylinder B is twice the radius of cylinder A. In what order do they reach the bottom?
a. A reaches the bottom first because it has the greater acceleration. b. A reaches the bottom first because it has a smaller rotatinal inertia. c. B reaches the bottom first because is experiences a larger torque. d. B reaches the bottom first because it travels a larger distance in one rotation. e. They both reach the bottom at the same time, because each has the same linear acceleration.
