Chandrasekhar limit (S. Chandrasekhar; 1930)
This is a limit that mandates that no white dwarf (a collapsed, degenerate star) may be more massive than approximates 1.4 masses solar. Any degenerate mass more massive has to collapse inevitably into a neutron star.
Examples of like and unlike parallel forces?
A mass M moves horizontally along a smooth rail. A pendulum is hung from M with a weightless rod and mass m at its end. Find the eigen frequencies and describe the normal modes
