Question

a simple pendulum complete 40 oscillations in 1 minutes find its frequency &timeperiod

Answer 1

Given
Oscillations =40
Time=1 min

$Frequency = \frac{number of oscillations}{total \: time}$

$f = \frac{40}{60} = 0.66667hz$

$Time period = \frac{1}{f}$

$t = \frac{1}{0.6667}$
T=1.5 seconds

This is ur ans hope it will help you in case of any doubt comment below

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
