Solution
The correct option is A 6000
Frequency = 100 Hz (given)
This means the source of sound vibrates:
100 times in one second
Therefore, number of vibrations in:
1 minute, i.e. in 60 seconds = 100 × 60 = 6000 times.
Frequency = 100 Hz (given)
This means the source of sound vibrates:
100 times in one second
Therefore, number of vibrations in:
1 minute, i.e. in 60 seconds = 100 × 60 = 6000 times.
