Question

You discover an metallic alloy having 212.6 x 1026 free electrons per cubic meter and resistivity of 51.73 nano Ohm-m. The internal dielectric constant inside the metal is 4.35 and there are 2.15 neutrons per proton in its nuclei. (a) Compute the mass density of the material (b) Compute the time between scattering events for the electrons, assuming the drude model of conduction (c) Compute the plasma frequency of the electrons. (d) A wire made of this metal is 5.29mm in radius and 4.35 m long and has 5.72 mV impressed across it. Compute the mean drift velocity of the mobile electrons.
