 a) Calculate the period of a simple pendulum if the length of the string is 1.5 meter?

g on the moon .

g on Moon is 1/6 of g on Earth, g on Earth = 9.8 m/s2

b) Calculate the period of the simple pendulum if you take to Mars.

g on Mars = 3.7 m/s2

a)    What is the ratio of the period of the above simple pendulum to the period of a simple pendulum which is 4 times longer ?

d) What happens to the period of the simple pendulum if you take it space?
