Question

A pendulum. Oscillation 100 times on 10s find its time period

Answer 1

Explanation:

100 times oscillation in 10 second

there for in 1 second no. of ocillation

100/10=10

time period =1/no of cycle in one second

so 1/10=0.1 second

0.1 second is the ans

Answer 2

Answer:

Given :

A pendulum oscillates 100 times in 10 seconds

To find :

Time period

Definitions:

Time period is defined as the time taken by the oscillatory object to complete one full oscillation.

Calculation:

Applying unitary method:

100 oscillations in 10 seconds

=> 1 oscillation in 10/100 second

= 0.1 second.

So the time period is 0.1 second.

Additional information:

Frequency is the inverse or reciprocal of the period.

so, freq. = 1/time period

=> freq. = 1/ 0.1 = 10 Hz

=> freq. = 10 Hz.
