Answer:
2 s
Explanation:
length of the pendulum, L = 1 m
acceleration due to gravity, g = 9.8 m/s^2
The time taken by the pendulum to complete one oscillation is called time period of the pendulum.
The formula for the time period of the pendulum is given by
[tex]T=2\pi \sqrt{\frac{L}{g}}[/tex]
[tex]T=2\pi \sqrt{\frac{1}{9.8}}[/tex]
T = 2 s
Thus, the time period of the pendulum is 2 second.
A pendulum whose time period is 2 s is called second's pendulum.
