Question

A pendulum completes 40 oscillations in one minute. Find its frequency.

Answer 1

We know,

Time period = Total time taken/No. of oscillations/

Then,

Time period= 60/40= 1.5s

We also know,

Frequency= 1/ time period

So

Frequency= 1/1.5= 10/15=0.666666Hz

Here is your answer. I hope it helps!!!!!

Answer 2

(1) Frequency = oscillation/Time

Frequency = 40/60

Frequency = 2/3Hz

Frequency = 0.67 Hz
