The time taken to perform 30 vibrations ...

The time taken to perform 30 vibrations is 30 times the time taken for a single vibration.

Text Solution

Verified by Experts

The correct Answer is:
true
Let the time taken for one vibration be T.
`therefore ` Time taken for 30 vibrations = 30T
= 30 (T)
` = 30 xx `(Time taken for single vibration)
