Question

The frequency of a source of sound in 100 HZ. How many times does it vibrate in a minute.......​

Answer 1

Answer:

Frequency:

The number of complete waves or cycles produced in one second is called frequency of the wave.

The number of vibrations per second is also called frequency.

SI unit of frequency in hertz (Hz).

1 hertz is equal to 1 vibration per second.

____________________________

Solution:

The frequency of 100 hertz means that the source of sound vibrates 100 times in 1 second.

[1min = 60 sec]

Number of vibrations in 1 second= 100

Number of Vibrations in 60 Second( 1min)=100× 60 = 6000

Hence, the source of sound vibrates 6000 times in a minute.

Hope this will help you......

Answer 2

Hertz means vibrations per second , if its 100 hertz then in 60 seconds it will vibrate 6000 times in a minute because 100 multiplied by 60 is 6000.
