Question

Обчислити силу тиску книжки масою 200г . , якщо площа книжки 400см² .​

Answer 1

Ответ: F=2(H)

Объяснение:

Дано:

m=200g=0.2kg

S=$400cm^{2}$=$0.04m^{2}$

F - ?

1) F=mg=0.2kg*$10\frac{H}{kg}$=2(H)

Answer 2

Calculating Pressure

To calculate the pressure exerted by the book, we can use the formula:

Pressure = Force / Area

Where: - Force is the force exerted by the book, and - Area is the area over which the force is distributed.

Calculation

Given: - Mass of the book = 200g = 0.2kg - Area of the book = 400cm² = 0.04m²

To find the force exerted by the book, we can use the formula:

Force = Mass x Acceleration due to gravity

The acceleration due to gravity is approximately 9.81 m/s².

So, Force = 0.2kg x 9.81 m/s²

Let's calculate the force: ``` Force = 0.2kg x 9.81 m/s² = 1.962 N ```

Now, we can calculate the pressure using the formula: Pressure = Force / Area

Pressure = 1.962 N / 0.04 m² = 49.05 Pa

Answer

The pressure exerted by the book with a mass of 200g and an area of 400cm² is approximately 49.05 Pascal.
