Question

a simple pendulum complete 40 oscillation in one minute find it's frequency and time.

answer with the working ​

Answer 1

Answer:

frequency=0.66

time period=1.25

Step-by-step explanation:

1 min=60 sec

time taken is 60 sec

$frequency= number \: of \: oscilations \div time \: taken$

f=40/60=2/3=0.66

$time \: period = time \: taken \div number \: of \: oscillations$

tp=60/40=6/4=1.25

hope it helps

Answer 2

Step-by-step explanation:

Given

Number of Oscillations, N=40

Time t=1min

Frequency f=tN=6040=0.667Hz

Time period,T=f1=1.5sec

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