Question

a pendulum oscilates 80 times in 5second find its time period and frequency​

Answer 1

Given : A pendulum oscillates 80 times in 5 seconds.

　

To find : What is its time period and frequency?

　

Using formula :

1) Frequency = Number of times the pendulum oscillates/Total number of time taken.

　

2) Time period = Number of oscillation per second/Frequency.

　

Calculations :

→ Frequency = 80/5

→ Frequency = 8 hertz

　

→ Time period = 1/8

→ Time period = 0.125 seconds

　

Therefore,

1. Frequency = 8 hertz.
2. Time period = 0.125 seconds.
