Question

A body is vibrating 6000 times in 1 minutes. Find the frequency and time period of the body

Answer 1

Hy there,
No. Of vibrations is 6000.
Time taken for vibration is 1 minute which is 60 second.
Frequency=No. Of vibrations/Time taken=6000/60=100 Hz.

Answer 2

Given : A body is vibrating 6000 times in 1 minutes.

　

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 = 6000/60

→ Frequency = 100 hertz

　

→ Time period = 1/100

→ Time period = 0.01 seconds

　

Therefore,

1. Frequency = 100 hertz.
2. Time period = 0.01 seconds.
