Question

find out the time period of a simple pendulum if it completes 40 oscillations in 1 minute​

Answer 1

Answer:

Explanation:

oscillation=40

time taken=60

Time taken in 1 sec = 40/60=2/3 Hz

frequency = 1/time period

time period = 1/frequency

time period = 1/2/3 =3/2 =1.5 sec

HOPE THIS HELPS YOU

Answer 2

Answer:

Total time taken/Number of oscillations

1 min =60 seconds

60/40

3/2 which is 1.5 seconds
