Radius of atmosphere
WebFeb 21, 2024 · Calculate the mass of the Earth's atmosphere given a mean pressure at the surface of 1.013 × 10 5 Pa and g = 9.81 m/s/s. I have been provided a hint in the textbook to use the hyrdostatic equation. From my understanding, the hyrdostatic equation is of the form ∂ p ∂ z = − ρ g. Here, ρ denotes density and thus ρ = m v ∂ p ∂ z = − m g v.

WebAtmospheric drag at orbital altitude is caused by frequent collisions of gas molecules with the satellite. It is the major cause of orbital decay for satellites in low Earth orbit.It results in the reduction in the altitude of a satellite's orbit. For the case of Earth, atmospheric drag resulting in satellite re-entry can be described by the following sequence: http://apollo.lsc.vsc.edu/classes/met130/notes/chapter1/thin_env_numb.html

One is the ratio of the … The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse effect), allowing life and liquid water to exist on the Earth's surface, and reduces t…
