Answer 1

→Question: What do you mean by second's pendulum?

↔Answer:

• A pendulum with time period if oscillation equal to 2 seconds is known as second's pendulum.
• The effective length of a second's pendulum is 1 metre approximately when g = 9.8m/s².
• Frequency of a second's pendulum = 1÷Time period = 1÷T
• 1 ÷ 2 = 0.5Hz

Answer 2

A pendulum with time period if oscillation equal to 2 seconds is known as second's pendulum.

The effective length of a second's pendulum is 1 metre approximately when g = 9.8m/s².
