the frequency of a source of a sound is 100hz .how many times does it vibrate in 1 min ???

f=100hz = 100times/second = 60*100times/60 seconds =6.000times/minute

So the answer is 6.000 times in 1 minute

'hz' means 'vibrations per second'. So, 100 hz is equivalent to 100 vibrations per second.

So, vibrations in 1 min = 60 * 100 = 6000
