Question

Жидкость налита в цилиндрический сосуд и давит на дно с силой F=2 H. Высота столба жидкости h=20 см,а площадь дна сосуда S=10 см². Определите, какая жидкость налита в сосуд.

Answer 1

Исходя из приведенной ниже формулы,следует ,что налита вода))

Answer 2

Calculating the Density of the Liquid in the Vessel

To determine the type of liquid in the vessel, we can calculate its density using the provided information.

Given: - Force exerted by the liquid on the bottom of the vessel, F = 2 H - Height of the liquid column, h = 20 cm - Area of the vessel's bottom, S = 10 cm²

Calculating the Pressure Exerted by the Liquid

The pressure exerted by the liquid can be calculated using the formula: P = F/S

Substituting the given values: P = 2 H / 10

Calculating the Density of the Liquid

The pressure exerted by a liquid at a certain depth is given by the formula: P = ρgh

Where: - ρ is the density of the liquid - g is the acceleration due to gravity - h is the height of the liquid column

By equating the two pressure equations, we can solve for the density of the liquid: 2 H / 10 = ρgh

Solving for Density

Given that the acceleration due to gravity, g, is approximately 9.81 m/s², we can convert the height of the liquid column to meters: h = 20 cm = 0.2 m

Substituting the values: 2 H / 10 = ρ * 9.81 * 0.2

Solving for ρ: ρ = (2 H) / (10 * 9.81 * 0.2)

Conclusion

By calculating the density of the liquid using the provided information, we can determine the type of liquid in the vessel.
