Question

Каково давление на глубине 2 метров, если барометр показывает нормальное атмосферное давление?

Answer 1

P(давление) = p((ро)плотность)*g(ускорене свободного падения)*h(высота,в данном случае - глубина).Плотность воды - 1000кг/м^3.
подставляем в формулу и получаем 1000*10(ускорение свободного падения)*2м = 20000Па.Ответ:20000Па

Answer 2

Pressure at a Depth of 2 Meters

At a depth of 2 meters, the pressure can be calculated using the formula for hydrostatic pressure, which is given by the equation:

P = ρgh

Where: - P is the pressure - ρ is the density of the fluid - g is the acceleration due to gravity - h is the depth

Given that the barometer shows normal atmospheric pressure, which is approximately 101,325 pascals (Pa) or 1.01325 bar we can calculate the pressure at a depth of 2 meters using the above formula.

Using the density of water, which is approximately 1000 kilograms per cubic meter (kg/m³) and the standard acceleration due to gravity, which is approximately 9.81 meters per second squared (m/s²), we can calculate the pressure at a depth of 2 meters.

P = (1000 kg/m³) * (9.81 m/s²) * (2 m) P ≈ 19620 pascals (Pa) or 0.1962 bar

Therefore, at a depth of 2 meters, the pressure is approximately 19620 pascals (Pa) or 0.1962 bar.

This calculation assumes that the fluid is water and the acceleration due to gravity is standard.
