Question

Визначити, на яку висоту піднявся літак, якщо за його бортом температура повіт- ря становить -30 °С, а біля поверхні Землі в цей час 24 °C тепла.

Answer 1

Ответ:

9 км

Объяснение:

1. 24°С -(-30°С) =54 °С - різниця t°

2. 54°C :6°C = 9 км

t° повітря з висотою знижується на 6°С на кожний кілометр.

Answer 2

Calculation of the Aircraft's Altitude

To determine the altitude to which the aircraft has climbed, we can use the lapse rate, which describes the decrease in temperature with increasing altitude in the Earth's atmosphere. On average, the temperature decreases by about 6.5 degrees Celsius per kilometer of altitude.

Given that the temperature outside the aircraft is -30 °C and the temperature near the Earth's surface is 24 °C, we can calculate the temperature difference between the two points.

Temperature difference = Temperature at the surface - Temperature outside the aircraft Temperature difference = 24 °C - (-30 °C) Temperature difference = 54 °C

Now, we need to convert the temperature difference into kilometers. Since the lapse rate is approximately 6.5 degrees Celsius per kilometer, we can divide the temperature difference by the lapse rate to find the altitude.

Altitude = Temperature difference / Lapse rate Altitude = 54 °C / 6.5 °C per km Altitude ≈ 8.31 km

Therefore, the aircraft has climbed to an altitude of approximately 8.31 kilometers.

Please note that this calculation assumes a standard lapse rate and does not take into account variations in the atmosphere. Additionally, the actual altitude may be affected by other factors such as air pressure and weather conditions.
