Answer 2

Answer:

• 440 hertz

-------------

Given:

• An object vibrates 2200 times in 5 seconds.

To find:

• the frequency of vibration.

Solution:

In this question, we are asked to find the frequency of the vibration. So, to find the frequency of the vibration, we've to use the formula of:

• Frequency = Number of times the object vibrates/time taken

Here,

• Number of times the object vibrates = 2200
• Time taken = 5 seconds

So,

→ Frequency = 2200/5

→ Frequency = 440

• Therefore, the frequency of vibration is 440 hertz.
