Question

A simple pendulum completes 80 oscillations in one minute. Find its frequency and time period.(Show the calculation

Answer 1

Answer:

1.5s

Explanation:

oscillation=40

time taken=60

in 1 sec = 40/60=2/3 Hz

frequency = 1/time period

time period = 1/frequency

time period = 1/2/3 =3/2 =1.5 sec

i hope it helps...........

Answer 2

Given:

No of oscillations of pendulum = 80

Time taken = 1 minute = 60 s

To Find:

The frequency and time period of the pendulum.

Calculation:

- The frequency of pendulum = No of oscillations / Time taken

⇒ f = 80 / 60

⇒ f = 1.33 Hz

- The time period of pendulum = 1 / frequency

⇒ T = 1 / 1.33

⇒ T = 0.75 s

- So, the frequency of the pendulum is 1.33 Hz and the time period of the pendulum is 0.75 s.
