Question

A vibrating body vibrates 50 times in 5 seconds. Will the sound be detected by human ear? Why or why not?

Answer 1

NUMBER OF TIMES BODY VIBRATES = 50

TIME TAKEN = 5 SECONDS

TOTAL HERTZ = 50 * 5

= 250.

SINCE , HUMAN EAR CAN HEAR SOUND BETWEEN 20 HERTZ AND 20000 HERTZ , SO THIS SOUND WILL ALSO BE AUDIBLE TO HUMAN EAR .

Hope this helps.
