The desert grasses, often curls their leaf to minimise water loss due to presence of

In the 75 litres of mixture of milk and water, the ratio of milk and water is 4:1. The quantity of water required to make the ratio of milk and water 3:1 is

When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb , water gets filled in the dropper. The rise of water in the dropper is due to :

When water is filled caerfully in a glass . One can fill it to a height h above the rim of glass due to the surface tension of water . To calculate h just before water starts flowing model the shape of the water above the rim as a disc of thickness h having semicircular edges as shown achematically in the figure When the pressure of water at the bottom of this disc exceeds what can be withstood due to the surface lension , the water surface breaks near the rim and water starts flowing form there if the density of water, its surface tension and the acceleration due to gravity are 10^(3)kgm^(-3),0.07Nm^(-1)and10ms^(-2) , respectively, the value of h (in mm) is _________
