Question

A simple pendulum on the surface of Earth is found to undergo 12.0 complete small-amplitude oscillations in 7.05 s. Find the pendulum's length Number

Answer 1

The pendulum's lenght is L= 0.0856m.

Step-by-step explanation:

T= 7.05 sec/ 12

T= 0.5875 sec

g= 9.8 m/s²

L= (T/2π)²*g

L= 0.0856 meters.
