Question

Деревянный брусок массой 12 кг и объемом 0,02 м3 плавает на поверхности воды. Чему равна сила Архимеда, действующая на брусок?

Answer 1

Ответ:100

Объяснение:

поскольку брусок только на половину в воде сила будет действовать только на ту половину которая в воде.

F=ρ(воды)*g*V(бруска)/2

F=1000*10*0.002/2=100

Answer 2

Calculation of the Archimedes' Force

To calculate the Archimedes' force acting on the wooden block, we need to use the formula:

Archimedes' force = weight of the fluid displaced by the object

In this case, the fluid is water, and the weight of the fluid displaced is equal to the weight of the wooden block.

Given: - Mass of the wooden block = 12 kg - Volume of the wooden block = 0.02 m^3

To calculate the weight of the wooden block, we can use the formula:

Weight = mass x gravitational acceleration

The gravitational acceleration on Earth is approximately 9.8 m/s^2.

Let's calculate the weight of the wooden block:

Weight = 12 kg x 9.8 m/s^2 = 117.6 N

Therefore, the weight of the wooden block is 117.6 Newtons.

Since the wooden block is floating on the surface of the water, the Archimedes' force acting on it is equal to its weight. Therefore, the Archimedes' force acting on the wooden block is also 117.6 Newtons.

Please note that the accuracy of this calculation depends on the assumption that the wooden block is completely submerged in water and that there are no other external forces acting on it.

Answer

The Archimedes' force acting on the wooden block is 117.6 Newtons.
