Hawking temperature: The temperature of a black hole is caused by the emission of the hawking radiation. For a black hole with mass m, it is illustrated as:
T = (hbar c^{3})/(8 pi G k m).
Determine the Velocity of the particle in terms of component veocities?
Kepler's 1-2-3 law: The other formulation of Kepler's third law, that relates to the mass m of the primary to a secondary's angular velocity omega and semi major axis a:
