need help with #5 please thank you

2. Find the mass of the air in a room 6.00 m by 8.00 m by 3.00 m. 3. Find the weight of 1.00 liter of air. 4. The point of a 10-penny nail has a diameter of 1.00 mm. If the nail is driven into a piece of wood with a force of 150 N, find the pressure that the tip of the nail exerts on the wood. The hatch of a submarine is 100 cm by 50.0 cm. What force is exerted on this hatch by the water when the submarine is 50.0 m below the surface. - 10.0 cm and d, 50.0 cm. If a In the hydraulic lift of figure, the diameter d, force of 10.0 N is applied at the small piston, (a) what force will appear at the large piston? (b) If the large piston is to move through a height of 2.00 m, what must the total displacement of the small piston be? 6. y2

Explanation / Answer

5-

Density of sea wate,r rho =1025 kg/m3

Abolute Pressure P = Patm + rho*g*h

P = 101.3 kPa + (1025 *9.81*50)

= 604.06 kPa

Calculate force.

F = P* A

= 604.06 kPa*(100*50*10^-4 m^2)

= 302 kN
