Question

A pendulum takes 0.5s to make 1 oscillation. How long it will take to make 5 oscillations?

Answer 1

Answer:

1 oscillation => 0.5 sec

5 oscillations => X esc

We can get the value of X by cross multiplication ie ,

X = 0.5×5

   = 2.5 sec

Hope it helped :)

Answer 2

Given,

A pendulum takes 0.5s to make 1 oscillation.

To find out,

How long it will take to make 5 oscillations?

According to the question,

Let us take the time taken by a pendulum to make 5 oscillations as 'X'.

A pendulum takes 0.5 seconds ......... 1 oscillation.

'X' seconds .......... 5 oscillations.

By cross multiplication

X = 5×0.5/1

X = 2.5

Therefore the time taken by a pendulum to make 5 oscillations is 2.5 seconds.
