Question

If atmospheric pressure is 1.01×10^5 pascal . how much force is exerted by air on the inside of a window plane which is 40 cm × 100 cm ?

Answer 1

Answer:

Explanation:

converting the area of the window in meter^2

40 *100 *10^-4= 0.4 m^2

so pressure=force/area

1.01 x 10^5= force / 0.4

force = 44000 newton
