In Figure C, there is a circular hole in the tin sheet. When the sheet is heated, will the hole also expand?

Two large holes are cut in a metal sheet will the distance between the holes increase or decrease on heating?

A squre hole of side length l is made at a depth of h and a circular hole is made at a depht of 4 h from the surface of water in a water tank kept on a horizontal surface (where l ltlt h). Find the radius r of the circular hole if equal amount of water comes out of the vessel through the holes per second.

Ozone hole is

Ozone hole is the area where

A large open tank has two holes in the wall. One is square hole of side L at a depth y from the top and the other is a circular hole of radius R at a depth of 4y from the top. When the tank is completely filled with water, the quantities of water flowing out per second from both holes are the same. Then R is equal to
