With what force does the air press on the surface of a page of a notebook, the dimensions of which are 16X20 cm2? atmospheric pressure 100kPa

To find out the force of air pressure on the surface of the page of the specified notebook, we will use the formula: F = P * S = P * l * b.

Data: P – atmospheric pressure (P = 100 kPa = 10 ^ 5 Pa); l – page length (l = 20 cm, in SI system l = 0.2 m); b – page width (b = 16 cm, in SI b = 0.16 m).

Let’s perform the calculation: F = P * l * b = 10 ^ 5 * 0.2 * 0.16 = 3.2 * 10 ^ 3 N.

Answer: Air should press on the surface of the page of the indicated notebook with a force of 3.2 kN.
