Question

Сколько литров воды выльется из до краёв заполненной ванны, если туда опустить стальную болванку массой 31,2 кг (плотность стали 7800 кг/м3)?

Answer 1

Дано:

m = 31,2 кг

ρ = 7800 кг/м³

Найти: V воды

Решение:

V воды = V болванки

V болванки = m болванки : ρ болванки (V=m/ρ)

V воды = V болванки = 31,2 кг / 7800 кг/м³ = 0,004 м³ = 4 литра

Ответ: 4 литра.

Answer 2

Calculating the Volume of Water Displacement

To calculate the volume of water that will be displaced when a steel bolt weighing 31.2 kg is submerged in a filled bathtub, we can use the principle of displacement. The volume of water displaced will be equal to the volume of the steel bolt.

The formula to calculate the volume of the steel bolt is:

Volume = Mass / Density

Given: - Mass of steel bolt = 31.2 kg - Density of steel = 7800 kg/m^3

Using the given values, we can calculate the volume of the steel bolt.

Volume = 31.2 kg / 7800 kg/m^3

Calculation

The volume of the steel bolt is calculated as follows: ``` Volume = 31.2 kg / 7800 kg/m^3 = 0.004 m^3 ```

Conclusion

The volume of water displaced by the steel bolt, when submerged in the filled bathtub, will be 0.004 cubic meters.
