Question

A body vibrates 100 times in 20 seconds. Calculate the time period and
frequency.

Answer 1

Answer:

The frequency of the body is 5 Hz and its time period is 0.2 s. Frequency is the number of vibrations made in a second.

Answer 2

Answer:

Frequency= 5Hz

Time Period= 0.2 sec

Explanation:

F= vibrations/time in seconds

 = 100/20 = 5Hz

T= time in seconds/vibrations

 = 20/100 = 0.2 s
