Question

СРОЧНО!!! ДАЮ 20 БАЛОВ!!! Який тиск буде на вершині гори, якщо в підніжжі тиск становить 735 мм.рт.ст.? Висота гори 4000 м.

Answer 1

Ответ:

4000м=4 км

4*100=400

735-400=335 мм. рт. ст.

Объяснение:

На кожен 1 км тиск опускається на 100 мм. рт. ст.

Answer 2

Calculating Pressure at the Top of the Mountain

To calculate the pressure at the top of the mountain, we can use 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 (in this case, air), - g is the acceleration due to gravity, and - h is the height of the fluid column.

Given: - The pressure at the base of the mountain is 735 mmHg (which is equivalent to 735 mm of mercury or 98.6 kPa), - The height of the mountain is 4000 m.

Calculation

First, we need to convert the pressure at the base of the mountain from mmHg to kPa.

1 mmHg = 0.133322 kPa

So, 735 mmHg = 735 * 0.133322 kPa = 97.98 kPa (approximately 98 kPa)

Now, we can calculate the pressure at the top of the mountain using the hydrostatic pressure formula.

Given: - Density of air (ρ) = 1.225 kg/m³ (at sea level and 15°C) - Acceleration due to gravity (g) = 9.81 m/s² - Height of the mountain (h) = 4000 m

Using the formula: P = ρgh

We get: P = (1.225 kg/m³) * (9.81 m/s²) * (4000 m) = 48,039 kPa

So, the pressure at the top of the mountain is approximately 48,039 kPa.
