Answer 2

Given : If a body vibrates 4000 times in 50 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 = 4000/50

→ Frequency = 80 hertz

　

→ Time period = 50/80

→ Time period = 0.675 seconds

　

Therefore,

1. Frequency = 80 hertz.
2. Time period = 0.675 seconds.
