Why do some large commercial airlines fly in the stratosphere? ​

Geography
1 answer:
aivan3 [116]3 years ago
6 0

Answer:

-Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.

Explanation:

In\ the\ digram\ AC\ is\ the\ monument\ and\ DE\ is\ the\ student.\\\\AC=AB+BC\\\\Let\ AB=x\\\\BC=Height\ of\ the\ eye\ of\ the\ student=DE=5\ ft\\\\\Rightarrow AC=x+5.................................eq(1)\\\\Student\ is\ standing\ at\ a\ distance\ of\ 25\ ft.\\\\CD=25\ ft\\\\BE=CD=25\ ft\\\\Angle\ of\ elevation=87.4\textdegree\\\\\angle AEB=87.4\textdegree\\\\Now\ in\ \triangle ABE\\\\\tan \angle AEB=\frac{opposite}{adjacent}=\frac{AB}{BE}\\\\\tan 87.4=\frac{x}{25}\\\\x=25\times \tan 87.4\\

x=25\times 22.02171001\\\\x=550.54275\ ft\approx 550.5\ ft\\\\Height\ of\ monument=AC=x+5\\\\Height\ of\ monument=550.5+5\\\\Height\ of\ monument=555.5\ ft

andreev551 [17]

Answer:

b. CO₂ gas and droplets of sulfuric acid

Explanation:

Atmosphere of Venus -

Venus atmosphere is occupied by the layer of gases .

The composition being , carbon dioxide which is very hot and dense in comparison to the carbon dioxide of the Earth .

<u>The pressure on the planet Venus is 93 bar with a temperature of 740 K.</u>

<u>The atmosphere of Venus have Opaque clouds made of sulfuric acid .</u>

Hence , the answer is CO₂ gas and droplets of sulfuric acid

The atmosphere of Venus is the layer of gases surrounding Venus. It is composed primarily of carbon dioxide and is much denser and hotter than that of Earth. The temperature at the surface is 740 K (467 °C, 872 °F), and the pressure is 93 bar (9.3 MPa), roughly the pressure found 900 m (3,000 ft) underwater on Earth.[1] The Venusian atmosphere supports opaque clouds made of sulfuric acid, making optical Earth-based and orbital observation of the surface impossible. Information about the topography has been obtained exclusively by radar imaging.[1] Aside from carbon dioxide, the other main component is nitrogen. Other chemical compounds are present only in trace amounts.
