Question

(ii) Banners and advertisement boards get ripped and blown off during cyclones​

Answer 1

Explanation:

Air exerts pressure. Wind blowing in high speed may break or displace many things. If holes are made in hanging banners and hoardings, then air can pass through these holes, which reduces the air pressure exerted on the banners and hoardings.

Answer 2

It is due to this pressure that the leaves of trees, banners, or flags flutter when the wind is blowing.The pressure of air inside the can decreases than the pressure exerted by the air from outside the can. As a result the can gets compressed.
