Question

Answer the below given questions . Writes steps , Formula and answers with Unit clearly .

An object is vibrating at 50 Hz. What is its time period? ( Ans 0 ,02 secs)

A simple pendulum makes 10 oscillations in 20 s. What is the time period and frequency of its oscillations?( Ans 2secs. and 0.5 Hz )

please answer the question if you don't know then please don't answer ​

Answer 1

Answer:

Here is your answer :-

1.The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

Here, a sound wave is vibrating at frequency 50 Hz. Hence, the time period T = 1/f = 1/50 = 0.02 s.

2.Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

Time period =20/10

=2s

Frequency =1/Period

Frequency =1/2

=0.5Hz
