CONGRATULATIONS!

For any 2010 seniors who might be reading this for some reason: we are DONE with Physics!!! I hope it was helpful! I don't really know what to do with this thing now, but I guess if future classes of Physics students really want to use this as a resource, they're welcome to!

Paper 3 Review

The outcome of a star depends on the star's initial mass (in terms of solar masses).
  • <0.25
  • 0.25 - 4 White dwarf with carbon/oxygen core
  • 4 - 8 White dwarf with oxygen/neon/magnesium core
  • 8 - 40 Neutron star
  • >40 Black hole
Fg = GMm/r^2

b = L/4πd^2 units: W/m^2

The Schwarzschild radius is the distance from the center of a black hole within which no light is able to escape.
