Question

11.A simple pendulum completes 40 oscillations in one-minute find its
a) Frequency
b) Time.
​

Answer 1

frequency=40/60=0.667 Hertz

time=1/0.667

=1.5 second

Answer 2

Answer:

Given

Number of Oscillations, N=40

Time t=1min

Frequency f= N/t = 40/60 =0.667Hz

Time period,T= 1/f =1.5sec

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