Question

A simple pendulum takes 55 s to complete 50 oscillations. What is the time- period of this pendulum?

Answer 1

Answer:

11/10second = 1.1second

Explanation:

time taken to complete 50oscillation = 55s

time taken to complete 1 oscillation= 55/50 = 11/10 s

Time period of a pendulum is time taken by it to complete 1 oscillation.

Time period of pendulum is 11/10 second= 1.1second

hope it helps, mark me brainliest

Answer 2

Given:

Time taken = 55 seconds

Number of oscillations = 50

To find:

The time period of this pendulum

Solution:

Time period = 1/frequency

Frequency = 50/55

Time for one oscillation is = 55/50

                                           = 1.1 second

Hence, the time period of this pendulum is 1.1 seconds.
