Question

What will be the time period in seconds if an object vibrates 1200 times in one minute?

Answer 1

Answer:

20.......................................

Answer 2

Answer:

The time period = 0.05seconds

Explanation:

Given,

Vibrations in one minute = 1200

To find,

The time period in seconds

Recall the concepts

Frequency = no. of vibrations/second

Time period = $\frac{1}{frequency}$

Solution:

Vibrations in one minute = 1200

Vibrations in 60 seconds = 1200

Vibrations in 1 second = $\frac{1200}{60}$ = 20

Time period = $\frac{1}{20}$ = 0.05seconds

∴ The time period = 0.05seconds
