उत्तर
A second’s pendulum is defined as a pendulum with a time period (T) of 2 seconds, meaning it takes 2 seconds to complete one full oscillation (from one extreme to the other and back).
One full oscillation = 2 seconds
Time from one extreme to the other is half of a full oscillation (half period), because it goes from one extreme to the other (half the motion).
∴ Time taken from one extreme to the other = `T/2 = 2/2` = 1 second.
