Question

calculate the time period of simple pendulum which completes 60 ossilations in 20 seconds​

Answer 1

Answer:

Given

Number of Oscillations, N=40

Time t=1min

Frequency f=

t

N

=

60

40

=0.667Hz

Time period,T=

f

1

=1.5sec

Hence, frequency is 0.667Hz and time period is 1.5sec

Answer 2

Explanation:

Oscillation=60

Time=20

In one second=60/20=3Hz

frequency=1/time period

Time period=1/frequency

Time period=1/3=0.33second.

Hope it helped.
