Pressure exerted by a liquid at a given point is:

A metallic sphere weighs 210g in air, 180 g in water and 120 g in an unknown liquid. Find the density of metal and of liquid.

Pressure exerted at any point of an enclosed liquid is transmitted

Pressure exerted by a liquid "__________" with the decrease in the density of liquid .

A bubble of gas released at the bottom of a lake increases to four times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water 10 m high, what is the depth of the lake?

A bubble of gas released at the bottom of a lake increases to four times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water 10 m high, what is the depth of the lake?

Pressure exerted by a liquid "________" with the increase in depth.

The pressure exerted by a certain mass of gas is 100cm of Hg at 30^(@)C . The gas is heated at constant volume. At what temperaute will the pressure exerted by the gas be 200cm of Hg?

If the excess pressure inside a soap bubble is balanced by an oil column of height 2 cm, then the surface tension of soap solution will be(r=1cm , density of oil =0.8g/cm 3 )
