A pendulum clock in a freely-falling elevator a) runs normally. b) runs a little fast. c) runs a little slow. d) runs very fast. e) none of these. A pendulum clock is set to run accurately at sea level. It is then brought to the top of a high mountain, where it is found to a) function unchanged. b) run slow. c) run fast. d) stop running. e) none of these. A mass oscillates on a spring. Each time the spring reaches its maximum extension, a person gives a light tap on the mass in the direction of the spring. The amplitude of the spring a) gradually decreases. b) decreases at first, then remains constant. c) remains constant. d) grows at first, then remains constant. e) grows with each oscillation. f) none of these....
