If you want volume density, you need to include the other two dimensions in terms of length, but you don't need to count the mass again, since that number is already included in the linear density.

However, as I recently learned, a medium's volume density is " inversely " proportional to the speed of sound in the medium, while the Bulk modulus, which is higher for incompressible fluids, is positively correlational to the sound speed.

You would, for example, be interested in the linear density of a particular type of cotton thread, but two different types of cotton thread would have different linear densities, even if the cotton fiber they were both composed of has the same volume density .-- 32 " "'04 : 31, 17 February 2010 ( UTC)

The continuity equation is applicable when there is some quantity " q " which can flow or move, such as mass, energy, electric charge, momentum, number of molecules, etc . Let " ? " be the volume density of this property, i . e ., the amount of " q " per unit volume.

In each of the three classes of Laves phase, if the two types of atom were perfect spheres with a size ratio of \ sqrt { 3 / 2 } \ approx 1.225, At this size ratio, the structure has an overall packing volume density of 0.710 Compounds found in Laves phases typically have an atomic size ratio between 1.05 and 1.67.

Is there an equation and graph that shows each of the basic conditions, i . e ., gravity, diameter, volume density rate of fusion of a star over time for each sequence ( big bang to cloud of hydrogen through the collapse of an iron core to the formation of a neutron star and eventually a black hole and beyond ) over time ? talk ) 04 : 29, 7 March 2010 ( UTC)
