| **With what force does the atmosphere press on the surface of a page of a notebook, the size of which is 16×20 at an atmospheric pressure of 0.1 MPA?**

To calculate the required force of atmospheric pressure on the surface of a page of a taken notebook, we will use the formula: F = P * S = P * a * b.

Values of variables: P – atmospheric pressure (P = 0.1 MPa = 0.1 * 10 ^ 6 Pa); a – the length of the notebook (a = 16 cm = 0.16 m); b is the width of the notebook (b = 20 cm = 0.2 m).

Let’s perform the calculation: F = P * a * b = 0.1 * 10 ^ 6 * 0.16 * 0.2 = 3200 N or 3.2 kN.

Answer: The atmosphere presses on the surface of the page of the taken notebook with a force of 3.2 kN.
