## QUESTION1: A pendulum oscillates 40 times in 4 seconds. Find its time period of the vibration. ## ANSWER: - Number of oscillation = 40 - Total time is taken = 4 seconds - Time period = Time ÷ Number of oscillation - = 1 seconds ÷ 10 - = 0.1 second The time period is 0.1 second. - Frequency =...
## QUESTION1: A pendulum oscillates 40 times in 4 seconds. Find its time period of the vibration. ## ANSWER: - Number of oscillation = 40 - Total time is taken = 4 seconds - Time period = Time ÷ Number of oscillation - = 1 seconds ÷ 10 - = 0.1 second The time period is 0.1 second. - Frequency = Number of oscillations per second. - = Number of oscillation ÷ time. - = 40 ÷ 4 seconds - Frequency = 10 per seconds or 10 hertz
