Question
Time period of simple pendulum is 1.2 seconds. What is the time taken by the pendulum to complete 30oscillations?(1) 25 s (2) 30 s (3) 36 s (4) 40
Solution
The time period of a simple pendulum is the time it takes for it to complete one full oscillation. In this case, the time period is given as 1.2 seconds.
To find the time taken by the pendulum to complete 30 oscillations, we simply multiply the time period by the number of oscillations.
So, 1.2 seconds/oscillation * 30 oscillations = 36 seconds.
Therefore, the pendulum takes 36 seconds to complete 30 oscillations. So, the correct answer is (3) 36 s.
