Why does a flag (or ensign) flutter when there is strong wind ? Explain.
Why does a flag (or ensign) flutter when there is strong wind ? Explain.
When there is strong wind, the kinetic energy of air at the end of flag is more and hence according to Bernoulli's equation pressure is low. The pressure at support of flag is a high. So due to pressure difference flag flutters.

Consider a water jar of radius $R$ that has water filled up to height $H$ and is kept on a stand of height $h$ (see figure) . Through a hole of radius $r$ $(r << R)$ at its bottom, the water leaks out and the stream of water coming down towards the ground has a shape like a funnel as shown in the figure. If the radius of the cross-section of water stream when it hits the ground is $x.$ Then

A liquid is kept in a cylindrical vessel which is being rotated about a vertical axis through the centre of the circular base. If the radius of the vessel is $ r $ and angular velocity of rotation is $\omega $, then the difference in the heights of the liquid at the centre of the vessel and the edge is
