Assuming that the atmosphere has a uniform density of `(1.3kg//m^(3))` and an effective height of 10 km, find the force exerted on an area of dimensions `100mxx80m` at the bottom of the atmosphere.

Diameter of a planet is 10d_(@) , its mean density is (rho_(@))/(4) and mass of its atmosphere is 10m_(@) where d^(@) , rho^(@) and m^(@) are diameter, mean density and mass of atmosphere respectively for the earth. Assume that mean density of atmosphere is same on the planet and the earth and height of atmosphere on both the planets is very small compared to their radius. Find the ratio of atmospheric pressure on the surface of the planet to that on the earth. If a mercury barometer reads 76 cm on the surface of the earth, find its reading on the surface of the planet.

The density of air near the earth's surface is 1.3kg m^-3 and the atmosphere pressure is 1.0xx10^5Nm^-2 . If the atmosphere has uniform density, same as that observed at the surface of the earth , what would be the height of the atmosphere to exert the same pressure .

A swimming pool has the dimensions shown in the figure . It is filled with water to a uniform depth of 8.00 m . The density of water = 1.00 xx 10^(3) kg//m^(3) What is the total force exerted on the bottom of the swimming pool ?

A breaker of circular cross section of radius 4cm is filled with mercury up to a height of 10cm . Find the force exerted by the mercury on the bottom of the beaker . The atmosphere pressure = 10Nm^-2 . Density of mercury =13600kg m^-3 , Take g= 10m/s^2 .

What is the mass of air in a room of dimensions 3mxx4mxx5m , when the density of air is 1.3 kg m^(-3) ?

A glass full of water has a bottom of area 20 cm^(2) , top of area 20 cm , height 20 cm and volume half a litre. Find the force exerted by the water on the bottom. Atmospheric pressure = 1.0 xx 10^(5) N//m^(2) . Density of water = 1000 kg//m^(-3) and g = 10 m//s^(2)

A swimming pool has the dimensions shown in the figure . It is filled with water to a uniform depth of 8.00 m . The density of water = 1.00 xx 10^(3) kg//m^(3) What is the total pressure exerted on the bottom of the swimming pool ?

The density of asir ner earth's surface is 1.3kgm^-3 and the atmospheric pressure is 1.0xx10^5Nm^-2 . If the atmosphere had uniform density, same as that observed at the surface of the earth what would be the height of the atmosphere to exert the same pressure?
