Question

Which of these explains the time period of a simple pendulum?
(a)The number of oscillations in one hour.
(b)The number of oscillations in one minute.
(c)Time taken to complete one full oscillation.
(d)Time taken by the pendulum to come at rest.

Answer 1

Answer:

I think option D is. the answer

Answer 2

The time period of a simple pendulum is explained by, time taken to complete one full oscillation.

To properly understand this answer, we have to know more about the time period of a simple pendulum.

Time period :

• Suppose, a simple pendulum is making N complete oscualltions in T seconds.
• So, the said simple pendulum will complete its one complete oscillation in (T/N) second.
• This time to complete one complete oscillation, or the (T/N) second for the said simple pendulum, is considered to be the time period.
• The time period has a SI unit similar to time, which is second.

Now, among the given statements only the statement mentioned in option C, (i.e. time taken to complete one full oscillation) is able justify the actual definition of the time period of a simple pendulum. (rest of the options are not correct explanations about the time period of a simple pendulum)

Hence, the time period of a simple pendulum is explained by, time taken to complete one full oscillation.
