Atmospheric pressure is nearly `100 kPa.` How large the force does the air in a room exert on the inside of a window pan that is `40 cm xx 80 cm`?

Atmospheric pressure is 1.01 xx 10^(5) Pa. How large a force does the air in a room exert on the inside of a window pan that is 50cm xx 100 cm ?

What force is required to exert a pressure of 40,000 Pa on an area of 1 cm^(2) ?

A block of wood is kept on a table top. The mass of wooden block is 5kg and its dimensions are 40cm xx 20cm xx 10cm. Find the pressure exerted by the wooden block on the table top if it is made to lie on the table top with its sides of dimensions (a) 20 cm xx 10cm and (b) 40cm xx 20cm .

A room has length 16 m, breadth 12m and height 10 m. The air pressure inside the entire room is 100 k Pa. Find the force exerted by air on the (i) floor (ii) sides of the room.

A wind with speed 40m//s blows parallel to the roof of a house. The area of the roof is 250 m^(2) . Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be (P_(air) = 1.2 kg//m^(3))

A wind with speed 40m//s blows parallel to the roof of a house. The area of the roof is 250 m^(2) . Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be (P_(air) = 1.2 kg//m^(3))

A submarine has a window of area 30 xx 30 cm^(2) on its ceiling and is at a depth of 100m below sea level in a sea. If the pressure inside the submarine is maintained at the sea-level atmosphere pressure, then the force acting on the window is (consider density of sea water = 1.03 xx 10^(3) kg//m^(3) , acceleration due to gravity = 10 m//s^(2)

A wind with speed 40 m//s blows parallel to the roof of a house. The area of the roof is 250 m^(2) . Assuming that the pressure inside the house is atmospheric pressure, the force exerted by the wind on the roof and the direction of the force will be : (rho_(air)=1.2 kg//m^(3))
