Question

what is the frequency of the frequency of an object if vibrates 20 times 20 seconds​

Answer 1

To find:

Frequency of an object if it vibrates 20 times in 20 seconds.

Calculation:

Frequency is the total number of vibrations (or complete oscillations) completed in one second. In other words, frequency can also be described as the reciprocal of time period of oscillation.

In 20 seconds , object vibrates for 20 times

=> In 1 second , object vibrates for $\dfrac{20}{20}$ times

=> In 1 second, object vibrates for 1 time.

Hence , frequency will be 1 Hz.

So, final answer is:

$\boxed{ \sf{frequency = 1 \: hz}}$
