Answer 2

Answer:

Sound produced by  is 0.333 Hz.

Explanation:

Given that

Time period(T) = 3 s

We know that relationship between time period and frequency of sound

  f = 1 /T Hz

By putting the values in the above formula we get

 f = 1 / 3 Hz

f=0.3333 Hz

So the  sound produced by  is 0.333 Hz.

We know that hearing range of human is varying from 20 Hz to 20 KHz .It means given sound produce by string of guitar could not hear by human.
