Answer 2

Answer:

A seconds pendulum is a pendulum whose period is precisely two seconds, one second for a swing in one direction and one second for the return swing, a frequency of 1/2 Hz. A pendulum is a weight suspended from a pivot so that it can swing freely.

Explanation:

Since the pendulum reaches its extreme position twice in one oscillation, the time period of a seconds pendulum is 2 seconds. On earth, the seconds pendulum has a constant length of approximately 1m.
