Suppose You Have a Pendulum Clock Which Keeps Correct Time

Suppose you have a pendulum clock which keeps correct time on Earth (acceleration due to gravity = 9.8 m/s²) . Without changing the clock, you take it to the Moon (acceleration due to gravity = 1.6 m/s²) . For every hour interval (on Earth) the Moon clock will record:

A) (9.8/1.6) h
B) 1 h
C)
D) (1.6/9.8) h
E)
