(sorry to people who don't like orbits) Imagine that the solar system consists of just the Earth circularly orbiting the Sun. If you wanted to get a spaceship to escape the solar system from the surface of Earth, what is the minimum velocity with respect to the Earth needed? Use the values of: Mass...

Yay orbits! Because the orbit is circular, we can equate the centripetal acceleration to the gravitational force to find that v_i^2 = \frac{GM}{R} . From there, we can use the Vis-Viva equation to find the semimajor axis of the new orbit. The equation is v^2 = GM \left( \frac{2}{R} - \frac{1}{a} \ri...

1. Pauli exclusion principle
2. An neutron star draws in matter from a companion star, which strikes the surface parallel to the star's motion, providing a "push" on the star, and speeding it up.
3. Gamma ray emissions

Nice job, all three answers are correct. Your turn!

1. What principle of quantum mechanics prevents white dwarfs and neutron stars from collapsing?
2. Explain how millisecond pulsars acquire the vast energy required to spin at up to 700 times per second.
3. What kind of emissions occur due to starquakes on a magnetar's surface?

I think there's been some confusion about the question and my solution, so I'll try to better explain my thought process. Orbiting at the same distance R is a valid approximation if M3 is far enough away from M1 (where the gravitational force between the two is negligible) but if all three masses ar...

Idk if this question even has a solution but here goes: Imagine 3 masses where M2>>M1 and the mass of M3 is negligible. M1 is orbiting around M2 at distance R with a period of P. M3 is also is orbiting M2 with the same period of P. What distance(s) could M3 be orbiting M2 from? Assume ideal circula...
