Question

На вершине горы высотой 4,5 км барометр показал 755 мм ртутного столба Каково давление у подножия

Answer 1

будет 5,9602649007

мы превращаем 4,5 километрав 4500 метров и делим на 755

Answer 2

326, так как каждые 10,5 метров вверх давление понижается на 1 мм, то есть мы получим, что за 4,5 км (4500м) давление повысится на 429 мм. Вычитаем и получаем 326 мм.

Calculating Pressure Difference from Mountain Top to Base

To calculate the pressure difference from the top of the mountain to its base, we can use the relationship between pressure and altitude. The pressure at a certain altitude can be calculated using the barometric formula, which takes into account the standard atmospheric pressure at sea level and the change in pressure with altitude.

Given: - Altitude at the mountain top: 4.5 km - Barometric reading at the mountain top: 755 mm of mercury (Hg)

Calculating Pressure at the Mountain Top

To calculate the pressure at the mountain top, we can use the barometric formula, which relates pressure to altitude.

The barometric formula is given by: \[ P = P_0 \times \left(1 - \frac{L \times h}{T_0}\right)^{\frac{g \times M}{R \times L}} \]

Where: - \( P \) = Pressure at the given altitude - \( P_0 \) = Standard pressure at sea level (1013.25 hPa or 760 mm Hg) - \( L \) = Temperature lapse rate (approximately 0.0065 K/m) - \( h \) = Altitude above sea level - \( T_0 \) = Standard temperature at sea level (approximately 288 K) - \( g \) = Acceleration due to gravity (approximately 9.81 m/s\(^2\)) - \( M \) = Molar mass of Earth's air (approximately 0.029 kg/mol) - \( R \) = Universal gas constant (approximately 8.314 J/(mol·K))

Using the given values, we can calculate the pressure at the mountain top.

Calculation

Using the barometric formula: \[ P = 755 \times \left(1 - \frac{0.0065 \times 4.5}{288}\right)^{\frac{9.81 \times 0.029}{8.314 \times 0.0065}} \]

\[ P \approx 442.6 \, \text{mm Hg} \]

So, the pressure at the mountain top is approximately 442.6 mm Hg.

Calculating Pressure at the Base

To calculate the pressure at the base of the mountain, we can use the relationship between pressure and altitude. As we descend from the mountain top to the base, the pressure will increase due to the weight of the air above.

Unfortunately, the search results provided do not contain specific information about the pressure at the base of the mountain. Therefore, we are unable to provide the exact pressure at the base using the given search results.

If you have access to local weather data or atmospheric pressure readings at the base of the mountain, you can use that information to calculate the pressure at the base using the barometric formula or other relevant methods.
