Answer :

Answer:

Frequency=?,number of oscillation=57,time=3.

There are two ways to go about this....

You can other use this formula: frequency=number of oscillation/time.

which is 57/3=19Hz.

OR.

You can use this formula:Period is time/number of oscillation.. which is..

3/57=0.053.

and frequency is 1/T....The "T" stands for period.

So since frequency is 1/T then it will be 1/0.053=18.8~19Hz..

The answer is option B.

Thank you for the question I hope it helps you
