Question

Дано: Какава довления внутри жидкости плотностью 900кг-м3 на глубине 30 см ?

Answer 1

P = ρgh = 900*10*0,3 = 2700 (Па)

Ответ: 2700 Па

Answer 2

Calculating Pressure at a Depth in a Liquid

To calculate the pressure at a depth in a liquid with a density of 900 kg/m³ at a depth of 30 cm, we can use the formula for pressure in a liquid:

Pressure (P) at a depth (h) in a liquid is given by the formula: P = ρgh Where: - P = pressure - ρ = density of the liquid - g = acceleration due to gravity - h = depth

Applying the Formula

Substitute the given values into the formula: ρ = 900 kg/m³ g = 9.81 m/s² (standard acceleration due to gravity) h = 0.30 m (converted from 30 cm to meters)

Now, we can calculate the pressure at this depth using the given formula.

Calculation

P = ρgh P = (900 kg/m³) * (9.81 m/s²) * (0.30 m)

P ≈ 2646.6 Pa

So, the pressure at a depth of 30 cm in a liquid with a density of 900 kg/m³ is approximately 2646.6 Pascal.
