Question

If a pendulum makes 15 oscillations in 3 seconds , What is the Time Period ?

Answer 1

Answer:

You need to remember the definition of Time period.

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

You need to apply unitary method.

See, as per the question,

the object performs 15 oscillations in 3 seconds.

therefore the same object will perform

1 oscillation in 3/15 = 1/5 = 0.2 seconds.

So the time period is 0.2 seconds.

Answer 2

Answer:

Time period is 0.2

Explanation:

As we know that time period is defined as the time taken to complete one full oscillation.According to the question the pendulum makes 15 oscillation in 3 second, therefore 3/15 =0.2
