Question

give reason , If the answer is correct then I will mark you as brainliest....​

Answer 1

Time taken to complete 20 oscillations= 32s

Time taken to complete 1 oscillation = 32/20s

=1.6s

Therefore, the time period of the pendulum is 1.6a

Answer 2

Answer:

• 1.6 seconds.

Explanation:

Given :

• Time period (t) = 32 s.
• Number of oscillations = 20 oscillations.

To find :

• Time period.

Solution :

We have,

• Time period for 20 oscillations = 32

To find,

• Time period for 1 oscillations = ?

⇒ 32/20 sec

⇒ 1.6 seconds is the time period of the pendulum.

Time period of a pendulum:

• Time taken to completed 1 oscillation.
