Question

на столе находится кусок кирпича объемом 200см². Вычислите силу тяжести, действующую на кирпич. Изобразите эту силу на чертеже.

Answer 1

Не ясно о каком кирпиче идет речь. Но если предположить, что это обычный глиняный кирпич, то его плотность будет равна около 1800 кг/м^3
m=V×p
m= 1800 кг/м^3 × 0.0002 м^3 = 0.36 кг
Fтяж. = gm
Fтяж. = 0.36 кг × 9.8 Н/кг = 3.528 Н
Ответ: Fтяж. = 3.528 Н

Calculation of the Force of Gravity on the Brick

To calculate the force of gravity acting on the brick, we need to know the mass of the brick and the acceleration due to gravity. The formula to calculate the force of gravity is:

Force of Gravity = mass x acceleration due to gravity

However, the given information only provides the volume of the brick, not its mass. To calculate the mass, we need to know the density of the material the brick is made of. Without this information, it is not possible to calculate the force of gravity on the brick accurately.

Representation of the Force of Gravity on the Diagram

Since we don't have the necessary information to calculate the force of gravity, we cannot accurately represent it on a diagram. The force of gravity is typically represented as a downward arrow, indicating the direction of the force. However, without knowing the magnitude of the force, we cannot accurately depict it on the diagram.
