The time period of a pendulum when taken to the Moon would: (1) remain the same (2) decrease (3) become zero (4) increase
by

1 Answer

Answer :

(4) increase Explanation: Since the pendulum rate will increase with an increase in gravity, and local gravity varies with latitude and elevation on Earth, pendulum clocks must be readjusted to keep time after a move. For example, a pendulum clock moved from sea level to 4000 feet will lose 16 seconds per day.
