With what force does the air press on the surface of a page of a notebook, the dimensions of which are 16×20 cm? Atmospheric pressure is normal.
a = 16 cm = 0.16 m.
b = 20 cm = 0.2 m.
P = 101325 Pa.
F -?
The pressure of the force P is the ratio of the force F to the area S on which this force acts.
Pressure P is determined by the formula: P = F / S.
Let us express the force of pressure: F = P * S.
Since the notebook has the shape of a rectangle, its area S is determined by the formula: S = a * b, where a and b are the lengths of the sides of the notebook.
F = P * a * b.
F = 101325 Pa * 0.16 m * 0.2 m = 3039.75 N.
Answer: the atmosphere presses on the notebook with a force of F = 3039.75 N.
