A boy is hanging from a horizontal branch of a tree. The tension in the arms will be maximum when the angle between the arms is

A boy of mass 40 kg is hanging from the horizontal branch of a tree. The tension in his arms is minimum when the angle between the arms is:-

Roots that hold horizontal branches of Banyan tree in the air are

If a simple pendulum of mass m is released from a horizontal position, find the tension in the string as a function of the angle theta with the horizontal.

Root which grow from branches of Banyan tree are

When a branch of a tree is shaken, some of the fruits may fall down. Why?

Show that the horizontal range is maximum when the angle of projection is 45^(@)

The U -tube shown in the figure has a uniform cross section. A liquid is filled up to heights h_(1) and h_(2) in the two arms and they are allowed to move. Neglecting viscosity and surface tension, find the state of the liquid when the levels equalize in the two arms. Find the correct statement.
