Question

QUESTION 6 When a tornado or hurricane hits, it's best to stay away from any windows. This is due to the drop in air pressure associated with the storms applying forces large enough to shatter the glass. To show this, assume the air pressure inside your house is 1.02 atm when a hurricane quickly drops the external air pressure down to 0.910 atm. If you're standing next to a window that has an area of 4.00 m2 What net force will be exerted outward on the window? 1 atm = 1.01 x 105 Pa. 5.37 104N 4.14 x 104N 4.46% 104N 4.78 x 104N 5 points Save Answer

Answer 1

Prusswee inside Pin = 1.02 atin Pressure outside Pout = 0.910 atm the Pressure difference Ap=0.1l adm AP=0111X1-01 X10S Po FOX AP= 1.111X 104 Pa So the net outward force on window of area A=4m2 is F = 161118104X4 N € 4.444X104N 04.46X104N
