Question

Літак піднявся на висоту 9 км визначити яка температура була біля поверхні Землі, якщо зараз вона становить (-30°с)

Answer 1

Ответ:

27

Объяснение:

$30 \times 9 = 270 \div 10 = 27$

Answer 2

Calculation of Temperature at Surface Level

To determine the temperature at the surface level of the Earth, given that the airplane has reached an altitude of 9 km and the current temperature is -30°C, we need to consider the lapse rate. The lapse rate is the rate at which temperature decreases with an increase in altitude.

The average lapse rate in the troposphere, the lowest layer of the Earth's atmosphere, is approximately 6.5°C per kilometer. This means that for every kilometer increase in altitude, the temperature decreases by 6.5°C.

To calculate the temperature at the surface level, we can use the following formula:

Temperature at surface level = Temperature at altitude + (Lapse rate * Altitude)

Given that the airplane has reached an altitude of 9 km and the current temperature is -30°C, we can substitute these values into the formula:

Temperature at surface level = -30°C + (6.5°C/km * 9 km)

Now let's calculate the temperature at the surface level:

Temperature at surface level = -30°C + (6.5°C/km * 9 km) Temperature at surface level = -30°C + 58.5°C Temperature at surface level = 28.5°C

Therefore, the temperature at the surface level of the Earth would be approximately 28.5°C if the airplane has reached an altitude of 9 km and the current temperature is -30°C.

Please note that this calculation assumes a standard lapse rate and does not take into account other factors that may affect the temperature distribution in the atmosphere.
