Question

An object completes 1600 vibrations in 20 sec calculate it’s frequency

Answer 1

Answer:

f = total vibration/total time

= 1600/20

=80

Explanation:

Hope it's help

Answer 2

Given:

The total vibration of the object = 1600

Total time is taken for vibration = 20 seconds

To find:

Frequency of the object.

Solution:

The frequency of the object is the number of vibrations per second.

So, the formula for the frequency is

$n = \frac{number \: of \: vibrations}{time}$

Where,

n is the frequency of the object.

Now, putting the values in the question in the above equation, we get,

$n \: = \frac{1600}{20} = 800$

The SI unit for the frequency is Hertz (Hz).

Hence, the frequency of the object is 800Hz.
