Question

Вычислите давление воды на дно одной из глубочайших морских впадин глубина которой 10900м. Плотность морской воды 1030кг м3

Answer 1

Дано:
h = 10900 м;
ρ = 1030 кг/м³;
p — ?

Решение:
p = ρgh,
p = 1030 * 10 * 10900 = 112270000 (Па).

112270000 Па = 112270 кПа ≈ 112 МПа.

Ответ: 112 МПа.

Answer 2

Calculating Water Pressure at the Bottom of a Deep Sea Trench

To calculate the pressure at the bottom of the Mariana Trench, which has a depth of 10900m, we can use the formula:

Pressure = Density × Gravity × Height

Where: - Density of seawater = 1030 kg/m^3 - Gravity = 9.81 m/s^2 (standard acceleration due to gravity) - Height = 10900m

Calculation

Using the given values: Pressure = 1030 kg/m^3 × 9.81 m/s^2 × 10900m

Result

Calculating this gives us a pressure of approximately 1.07 × 10^8 pascals (Pa) at the bottom of the Mariana Trench.
