Question

Suppose you have a pendulum clock which keeps correct time on Earth(acceleration due to gravity = 1.6 m/s2). For ever hour interval (on Earth) the Moon clock:
A) (9.8/1.6)h
B) 1 h
C) the square root of 9.8/1.6 h
D) (1.6/9.8)h
E) the square root of 1.6/9.8 h

Answer 1

The time-period of a simple pendulum is

Time =  2 π √(length/grav-accel)

After unraveling the question, then completing it, and working out what I believe it's trying to ask, the choice that correctly answers the question that I have invented is choice-E .
