$A$ chimpanzee swinging on a swing in a sitting position,stands up suddenly,the time period will

Time period of a simple pendulum is $T$ inside a lift when the lift is stationary. If the lift moves upwards with an acceleration $g / 2$,the time period of the pendulum will be

If $R$ is the radius of the earth and the acceleration due to gravity on the surface of the earth is $g = \pi^2 \ m/s^2$,then the length of the second's pendulum at a height $h = 2R$ from the surface of the earth will be:

Define a simple pendulum and the length of the pendulum.

The height of a swing changes during its motion from $0.1\, m$ to $2.5\, m$. The minimum velocity of a boy who swings in this swing is ..... $m/s$.

The length of a simple pendulum is increased by $44\%$. The percentage increase in its time period will be ..... $\%$
