Question

The frequency of a sound is 10 Hz. Find its time period and the number of times it vibrates in a 4 minute.

Pls answer

​

Answer 1

Answer:

Number of times Vibrates in 4 minutes is 2400

Explanation:

given,

frequency = 10hz

find,

time period = ?,

vibrating in 4 min. = ?

solution,

Frequency is defined as the number of oscillations per second. It is given by the relation:

Frequency = Number of Oscillations / Total Time

Number of oscillations = Frequency × Total time

Given, Frequency of sound = 10 Hz

Total time = 4 min = 240 sec

Number of oscillations/Vibrations = 10 × 240 = 2400

Hence, the source vibrates 2400 times in 4 minute, producing a frequency of 10 Hz.
