Question

Каков объем жедезнобитонной плиты,если в воде на нее действует выталкивающая сила 10000Н​

Answer 1

Ответ: 1м³

Объяснение:

Дано:

Fa=10000Н

g=10Н/кг

ρ=1000кг/м³

-------------------

V-?

Fa=ρgV

V=Fa/(ρg)=10000/(1000*10)=1м³

Answer 2

Calculating the Volume of an Iron Plate in Water

To calculate the volume of an iron plate in water when a buoyant force of 10000N is acting on it, we can use the principle of buoyancy and Archimedes' principle.

Buoyant Force: The buoyant force acting on an object immersed in a fluid is equal to the weight of the fluid displaced by the object.

Archimedes' Principle: The buoyant force acting on an object is equal to the weight of the fluid displaced by the object.

Formula for Calculating Volume

The formula to calculate the volume of an object immersed in a fluid is:

V = F_b / ρg

Where: - V = Volume of the object - F_b = Buoyant force acting on the object - ρ = Density of the fluid - g = Acceleration due to gravity

Applying the Formula

Given that the buoyant force acting on the iron plate is 10000N, we can use the formula to calculate the volume. The density of water is approximately 1000 kg/m^3, and the acceleration due to gravity is approximately 9.81 m/s^2.

V = 10000N / (1000 kg/m^3 * 9.81 m/s^2)

V ≈ 1.02 m^3

Therefore, the volume of the iron plate in water, when a buoyant force of 10000N is acting on it, is approximately 1.02 cubic meters.
