Question

A simple pendulum makes 15 oscillations in 5 seconds . What is the frequency and time period of simple pendulum

Answer 1

Answer:

For 15 oscillation it takes 5 sec

For one oscillation Tme period = 30/5 = 2sec

Frequency = 6/ Time period

=1/2=0.5 Hz

Answer 2

ANSWERS:

no. of oscillation =15

Time taken =5 sec

no. of 1 oscillation time period =

$= \frac{5}{15} sec$

$= \frac{1}{3} sec$

$Frequency = \frac{1}{ \frac{1}{3} }$

$= \frac{1 \times 3}{1}$

$= 3hz \: answer$
