Eccentricity of Elliptical Orbit of a Satellite

A satellite has an elliptical orbit around the earth with one focus at the earth's center, E. The earth's radius is 4000 miles, the highest point that the satellite is from the surface of the earth is 800 miles, and the lowest is 200 miles. Find the eccentricity of the satellite's orbit.

Why does the spacing for energy levels get smaller as n becomes larger ?

Apart from analyzing the results from the Bohr Formula Is there a reason why the spacing gets smaller? Such as the orbits being further away from the nucleus so there is less pull on the electrons. See the link below for the diagram.

Bohr radii and energy levels.

An electron of mass m is in a circular orbit in the potential U=0.5 k r^2. Using Bohr's quantization rule, find the allowed orbital radii and energy levels of this electron.

Earth and Sun System Calculations

In this problem you are to make use of the formula P^2 = 4(pi)^2/mu *a^3, together with the fact that mu = G(m1 + m2). Assume, as is approximately correct, that the semi-major axis for the Earth's orbit about the Sun is 93 million miles and that the period is 365 days. Also assume that the semi-major axis for the Moon's orbit ab

Calculating gravitation for Halley's Comet

The orbital period of Halley's Comet is calculated to be 75.5 years. Many other comets have orbits that extend much farther from the sun, and hence have much longer periods. At aphelion, a typical long-period comet is about from the sun; at perihelion, it passes inside the earth's orbit. 1. Estimate the orbital period of suc

Gravitation of a Satellite

If a satellite is in a sufficiently low orbit, it will encounter air drag from the earth's atmosphere. Since air drag does negative work (the force of air drag is directed opposite the motion), the mechanical energy will decrease.
