Question

In the pendulum formula T=2pi. Please help read the problem on the picture please help!!!;$;$;!;!;!;)$;!;!;!;$;$;$!;!;);$;$$

Answer 1

`T` is the pendulum's period/time it takes for it to complete a full swing and
`L` is its length. So

`3.27\,\mathrm s=2\pi\sqrt{(1\,\mathrm m)/(g_(\rm Mars))}\implies g_(\rm Mars)\approx3.69\,(\rm m)/(\mathrm s^2)`

and the closest answer is B.
