Answer:
A greater period.
Explanation:
The period of a simple pendulum is represented by the following formula:
[tex]T = 2\pi\cdot \sqrt{\frac{l}{g} }[/tex]
Where:
[tex]l[/tex] - Length of the pendulum
[tex]g[/tex] - Gravity constant
Given that gravity constant in the Moon is less than on Earth, period shall be greater.
