Question

1. A simple pendulum completes 40 oscillations
in one minute. Find its (a) frequency, (b) time period.
​

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

Answer:

so, here is its frequency and its time period

hope it helps.
