Question

A simple pendulum makes 20 oscillations in 2 minutes. What is the time period and frequency of its
oscillation?

Answer 1

Answer:

No. of oscillation = 20

time taken = 2 min or 120 sec.

frequency = osci. ^ time taken

= 20 ^ 120

= 1^ 6 hertz

time period = 1^ frequency

= 1^ 1^ 6

= 1*6^1

= 6 seconds
