Question

A plane flies at an altitude where the atmospheric pressure is 200mmHg. If the pressure inside the cabin is maintained at 760mmHg, calculate the net force on a window whose area is 800cm²

Answer 1

net force= net pressure*area=(760-200)mmHg * area
now you need to conver mmHg to Pascals
101.3 P=760mmhg
net force=560*101.3/760 * area
now convert cm^2 to m^2
10^4 cm^2=1m^2
go for it.
