Question

1) a vibrating object take 20 second to complete 16000 vibration . what can be it's frequency of vibration?
anyone please answer fast i will mark you as brainlist

Answer 1

Answer:

frequency = no. of oscillations / time taken

= 1600/ 20

= 80 Hz

Answer 2

Answer:

The frequency of vibration is 800 Hz

Explanation:

Given :

A vibrating object take 20 second to complete 16000 vibrations.

To find :

the frequency of vibration

Solution :

Frequency :

• It is the number of vibrations per second.
• One vibration per second equals 1 Hz (hertz)
• Unit : Hertz
• Dimensional formula : [M°L°T⁻¹]

A vibrating object take 20 second to complete 16000 vibrations.

To find the frequency of vibration, we have to find the number of vibrations in one second.

 frequency = number of vibrations/time taken

 frequency = 16000/20

 frequency = 800 Hz

∴ The frequency of vibration is 800 Hz
