Определение формулы веса тела в жидкости.

Answer 1

Definition of the Formula for Weight in a Fluid

The formula for calculating the weight of an object in a fluid is based on the principle of buoyancy. When an object is submerged in a fluid, it experiences an upward force called buoyant force, which is equal to the weight of the fluid displaced by the object. The weight of the object in the fluid can be calculated using the following formula:

Weight in Fluid = Weight in Air - Buoyant Force

Where: - Weight in Fluid is the weight of the object when submerged in the fluid. - Weight in Air is the weight of the object in the absence of any fluid. - Buoyant Force is the upward force exerted on the object by the fluid.

The buoyant force can be calculated using Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object. The weight of the fluid displaced can be calculated using the formula:

Weight of Fluid Displaced = Density of Fluid x Volume of Fluid Displaced

Where: - Density of Fluid is the density of the fluid in which the object is submerged. - Volume of Fluid Displaced is the volume of the fluid displaced by the object.

By substituting the formula for the weight of the fluid displaced into the formula for the weight in fluid, we can derive the following formula:

Weight in Fluid = Weight in Air - (Density of Fluid x Volume of Fluid Displaced)

It is important to note that the density of the fluid and the volume of fluid displaced are crucial parameters in calculating the weight of an object in a fluid. The density of the fluid is typically given in kilograms per cubic meter (kg/m^3), while the volume of fluid displaced is measured in cubic meters (m^3).
