Answer:
A greater period.
Explanation:
The period of a simple pendulum is given 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
Since acceleration due to gravity is smaller in the Moon, period will be greater.
