Question

Помогите пожалуйста определите давление на глубине 0.6 м в воде, керосине,ртути. это первое вычислите давление воды на дно одной из глубочайших морских впадин- Марианской, глубина которой 10 900 м. Плотность морской воды 1030 кг в кубическом метре помогите спасибо заранее

Answer 1

: 6 кПа; 4,8 кПа; 81,6 кПа.

Answer 2

Calculating Pressure at a Depth of 0.6m in Water, Kerosene, and Mercury

To calculate the pressure at a depth of 0.6m in water, kerosene, and mercury, we can use the formula for pressure:

Pressure = Density x Gravity x Depth

Let's calculate the pressure for each substance:

1. Water: - Density of water = 1030 kg/m³ - Gravity = 9.8 m/s² - Depth = 0.6m

Pressure in water = 1030 kg/m³ x 9.8 m/s² x 0.6m = 6032.4 Pa

2. Kerosene: - Density of kerosene varies, but for this calculation, we'll assume a density of 800 kg/m³ - Gravity = 9.8 m/s² - Depth = 0.6m

Pressure in kerosene = 800 kg/m³ x 9.8 m/s² x 0.6m = 4704 Pa

3. Mercury: - Density of mercury = 13600 kg/m³ - Gravity = 9.8 m/s² - Depth = 0.6m

Pressure in mercury = 13600 kg/m³ x 9.8 m/s² x 0.6m = 80064 Pa

Calculating Pressure at the Bottom of the Mariana Trench

The Mariana Trench is one of the deepest oceanic trenches, with a depth of 10,900m. To calculate the pressure at the bottom of the Mariana Trench, we'll use the same formula:

Pressure = Density x Gravity x Depth

Given the density of seawater as 1030 kg/m³ and a depth of 10,900m:

Pressure at the bottom of the Mariana Trench = 1030 kg/m³ x 9.8 m/s² x 10,900m = 107,194,200 Pa

Please note that the pressure at such extreme depths is incredibly high and can reach values of several hundred megapascals.

I hope this helps! Let me know if you have any further questions.
