2. On the inside of an airplane the air pressure is about 85% of the atmospheric pressure
at sealevel while outside, when it is cruising, the pressure is about 25% of the sealevel atmospheric pressure. If a window is 0.46 m in diameter, what is the net outward
force on the window in Newtons? What is the force in pounds?
