Luminosity is approximate
Luminosity is approximately equal to the seven-halves power of this quantity for main-sequence stars, and negative h bar squared is divided by two times this quantity in the Hamiltonian operator. The "reduced" form of this quantity is frequently employed in two body problems. The "flow rate" associated with this quantity in incompressible fluids must be constant according to the continuity equation, and a form of energy is equal to this quantity multiplied by the square of the speed of light. For 10 points, identify this quantity commonly measured in grams.
