Question

What is the time period of simple pendulum if it undergoes 20 oscillation in 5 seconds.

Answer 1

Answer:

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum. Hence, the Time period and frequency are 2 seconds and 0.5 Hertz respectively.

Answer 2

Answer:

hope that helped :)

Explanation:

Simple Pendulum is a very small heavy metal bob suspended at a point from a firmly fixed support using a single strand thread so that it oscillates freely. The distance between the point of suspension and centre of bob is called the length of the pendulum.  

One oscillation: One complete to and fro motion of the oscillating body is called one oscillation.  

Frequency: It is the number of oscillations made by the body in one second.

Time Period: It is the time taken by a body to complete one oscillation.

Hence, the Frequency and Time period are calculated as follows.

Time period = Time taken by the pendulum/Number of oscillations made by the pendulum.

=0.5Hz

Hence, the Time period and frequency are 2 seconds and 0.5 Hertz respectively.
