Question

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

Answer 1

Answer:

In 15 seconds, oscillations - 5

therefore,in one second, oscillations - 5/15 - 1/3

Explanation:

Therefore,in 60 seconds,no of oscillations - 1/3 × 60 - 20

Answer 2

GIVEN,

a simple pendulum takes 55 seconds to complete 50 oscillations

TO FIND,

time period T of the simple pendulum.

SOLUTION,

A simple pendulum is a device in which the point mass is suspended from fixed support and is coupled to a light inextensible thread.

The time period of a simple pendulum is the time required by the pendulum to complete one oscillation.

Therefore, the time period = $\frac{time for a number of oscillation}{no of oscilltion}$

substituting the values,

                                          T= $\frac{55}{50}$

                                         ∴ T= 1.1 seconds

the time period is 1.1 seconds.

HENCE THE TIME PERIOD IS 1.1 SECONDS THAT MEANS THE PENDULUM TAKES 1.1 SECONDS TO COMPLETE ONE OSCILLATION.
