By reviewing the derivation of the virial theorem, write down the conditions necessary for an astronomical system to be "virialized" (i. e. - for the virial theorem to apply. based on these conditions, speculate on whether we should expect the milky way galaxy to be "virialized," that is, should we expect that today the total gravitational potential energy u and total kinetic energy k of the milky way obeys the relationship u-2k.
