Question

A pendulum oscillates 60 times in 6 seconds. Find its time period and frequency.(CLASS 8TH)

Answer 1

time period= time taken/ no of oscillations
= 6/60= 1/10 =0.1sec

frequency= no of oscillations / sec
60/6
= 10 oscillations

Answer 2

Answer: The correct answers are 0.1 s and 10 oscillations

Explanation:

Calculate the time period.

$Time period = \frac{Time taken}{Number of oscillations}$

Put Time taken = 6 s and Number of oscillations = 10.

$Time period = \frac{6}{10}$

$Time period =0.1 s$

Calculate the frequency.

$frequency = \frac{1}{T}$

Here, T is the time period.

Put T= 0.1 s.

$frequency= 10 Hz$

Therefore, the time period is 0.1 s and the frequency is 10 Hz.
