Question

The frequency of a source of sound is 100 Hz . How many times does it vibrate in a minute?

Answer 1

Number of vibrations produced in 1 second = 100 

Number of vibrations produced in 1 minute (60 s) = 100Hz x 60s = 6000

I hope it is correct......

Answer 2

Hi.
The frequency of a sound is the number of vibrations made by the sound waves in 1 second.
Thus,
In 1 seconds the frequency of sound is 100 Hz.
Therefore, in 1 minute (60s), the frequency of the sound = 100 Hz× 60
= 6000 Hz.
Thus the freqiency of the sound made by the source in 1 minute is 6000 Hz.

Hope it will help u
