Pendulum Period Comparison

SATPHY-0KGQ9V

The length of pendulum 1 is four times the length of pendulum 2.

How does the period of pendulum 1 compare to the period of pendulum 2?

A

The period of pendulum 1 is four times as much as the period of pendulum 2.

B

The period of pendulum 1 is sixteen times as much as the period of pendulum 2.

C

The period of pendulum 1 is twice as much as the period of pendulum 2.

D

The period of pendulum 1 is one-half as much as the period of pendulum 2.

E

We cannot determine the comparisons of the periods of the pendulums without knowing the masses of the pendulums.
