To allow density' based separations, a centrifugal field is applied by either a mechanical action or by accelerating the particles around a rotational axis. Particle acceleration is given by: ac = rw2. r = radial distance from center of rotation. ω = angular velocity, (rad/s) The centrifugal force, Fc, is given by:

The density of urine varies in the ...

Density: Meteorites are usually quite heavy for their size, since they contain metallic iron and dense minerals. Magnetic: Since most meteorites contain metallic iron, a magnet will often stick to them. For "stony" meteorites, a magnet might not stick, but if you hang the magnet by a string, it will be attracted.
