No. Imparted angular momentum(kinetics) when the mass accretes(particle collisions) out of a nebula to form the star and its planets.

=spcgliderTrue. It also has a little to do with whether or not the planet is liquid or solid core, yes?
In regards to a discrete rotating mass the only factors that retard the rotation are those processes that turn potential energy into transfer energy, Gravitational drag, frictional drag inside the mass, Mass redistribution inside the gravitational influence, heat transfer-at least a dozen things that I could name(collisions?) that could affect angular momentum.

Of course, we don't even REALLY know if Earth has a liquid or solid core and so don't know precisely if there is any sort of standard for planet guts in general.
Solid; as in a metal that perfectly reflects sound waves. NO REFRACTION AT ALL.

But as has been shown time and again, if you try to apply too much real science to Galactica, you either end up re-writing the script OR re-writing the laws of physics!

True; but not as much as you have to do in Star Wars(After Lucas screwed it up.) or Star Wreck.(after Berman trashed it.)

As always;
