Answer 2

Answer:

The effective length of the seconds' pendulum, at a place where g= 9.8 ms² (the average value), is nearly 1 metre.

Explanation:

The pendulum of a clock which we use to note time in our house, is a seconds' pendulum.

It takes time 1 s in moving from one extreme to the other extreme, so it's time period is 2 s.

Thus, a pendulum with a time period of oscillation equal to two seconds, is known as a seconds pendulum.
