Below we will give the mathematical definition and substitute mobility (given as μ n) into the current density equation. μn = νd E = qτ m ∗. Jn = nqμnE. From these equations we can then obtain the conductivity of the material in terms of the ... male anime hairstylesThermal velocity or thermal speed is a typical velocity of the thermal motion of particles that make up a gas, liquid, etc. Thus, indirectly, thermal velocity is a measure of temperature. Technically speaking, it is a measure of the width of the peak in the Maxwell–Boltzmann particle velocity distribution. Note that in the strictest sense thermal velocity is not a velocity, since velocity usually describes a vector rather than simply a scalar speed. malean medication
