Question

A pendulum complete 20 oscillation in 38 sec. what is it time period

Answer 1

Answer:

The period of a simple pendulum is the time to complete a single vibration or a single oscillation. It is solved by dividing the elapsed time to complete a number of vibrations.

T = 38 seconds / 20 oscillations or 1.9 seconds per oscillation. The period of the given simple pendulum is 1.9 seconds.

hope it helps❤

Answer 2

Answer: 1.9 seconds

Explanation:

❍ Given :-

• Number of oscillations = 20
• Total time taken to complete all the oscillations = 38 seconds

❍ To Find :-

• Time period of given pendulum

❍ Solution :-

➸ According to the time period formula,

$\fbox{\sf{Time \: period = \dfrac{Total \: time \: taken}{No \: of \: oscillations}}}$

$\sf→{Time \: period = \dfrac{38}{20}}$

$\sf→{Time \: period = 1.9 \: sec}$

Hence, the time period of given pendulum is 1.9 sec.
