Question

a) How can we make a simple pendulum?
b) A simple pendulum takes 20 seconds to complete 10 oscillations. Find the time period
of the pendulum.​

Answer 1

Answer:

When a simple pendulum makes 10 oscillations in 20 seconds, the time taken for each oscillation = 20/10 = 2 seconds. Hence, as the time period is calculated to be 2 seconds, the frequency of oscillation = 1/T = 1/ 2 = 0.5 Hertz.

Answer 2

Answer:

0.50 sec.

Explanation:

T = Total time/ Total Oscillations = 20 seconds/10 oscillations = 2 seconds for 1 oscillation. The time period (T) of a simple pendulum is defined as the time taken by it to complete one oscillation. T = 10/20 = 0.50 seconds
