The time taken by a simple pendulum to complete 20 oscillations is given in the table as shown below study the and write the following steps in sequential order to determine the frequency of its oscillations. (A). Find the reciprocal of average time period (T). (B). Find the ratio of time and number of oscillations. (C). Find the average of the values obtained in the previous step.A. BCAB. ABCC. ACBD. Both (a) and ( c)

Answer» Correct Answer - A
Find the time period in each step.
Time period = `("time taken for 20 oscillations")/("Number of oscillations")`
Find the average value of the time period obtained in the percous step.
Find the reciprocal of the average time period as frequency.
