A boat has a porthole window, of area 0.00849 m^2, 6.25 m below the surface. The density of sea water is 1027 kg/m^3. The air inside the boat is at 1 atm. What is the net force on the window?

outward.

Explanation:

= Density of water =

g = Acceleration due to gravity =

h = Height of the water = 6.25 m

A = Area of the window =

= Internal pressure of the boat =

Pressure by the water on the window

Net pressure on the window

Force is given by

Net force on the window is outward.

the independent variable, or the one that is intentionally manipulated is the speed.
