Question

An object vibrates 2400 times in 15seconds. Find its time period andfrequency​

Answer 1

Answer:

Given:

An object vibrates 2400 times in 15 seconds.

To find:

Frequency and Time period

Concept:

Time period is defined as the time taken by an object to complete one full oscillation.

Frequency is the reciprocal of the time period.

Formulas used:

Frequency = 1/(Time period)

Calculation:

Apply unitary method:

2400 oscillations in 15 seconds

=> so 1 oscillation in 15/2400

= 0.00625 seconds

= 6.25 milli- seconds.

Now frequency = 1/(Time period)

=> freq. = 1/0.00625

=> freq. = 160 Hz.

Answer 2

an object vibrates 2400 times in 15 seconds find its time period and frequency
