Answer:

22044.3 N

Explanation:

We are given that

Dimension of office window=[tex]3.7m\times 2.1 m[/tex]

Area of office window=[tex]l\times b=3.7\times 2.1=7.77 m^2[/tex]

Outside air pressure=P1=0.972 atm

Inside pressure,P2=1.0 atm

Pressure=P2-P1=1-0.972=0.028 atm=0.028\times 101325 Pa=2837.1 Pa

1 atm=101325 Pa

Force,F=PA

Using the formula

[tex]F=7.77\times 2837.1=22044.3 N[/tex]

Hence, the net force pushes out on the window=22044.3 N
