15. The free electron model for a metal assumes that the conduction electrons can be approximated by a gas of free electrons where the only important parameters for the gas are n, the number density of electrons, and $\tau$, the time between collisions. (a) Show that in this model the electrical conductivity of a metal can be expressed as $\sigma = \frac{ne^2\tau}{m}$ (b) Estimate the collision time $\tau$ for an electron in copper. Where the resistivity of copper metal is $1.7 \times 10^{-6}$ ohm-cm and the atomic density of cooper is $8.5 \times 10^{22}$ toms/cm$^3$. Assume each copper atom contributes one conduction electrons. (c)Assume the conduction electrons' average speed is given by the classical equipartition result: $\frac{1}{2}mv^2 = \frac{3}{2}kT$ Find the electrons' mean free path. (d)Assume instead that Cu is well described by the Sommerfeld model (only the electrons within an energy range $k_BT$ of the Fermi level can be excited thermally) of a free electron gas. Calculate the fermi energy, fermi temperature and the fermi velocity $v_F = \frac{\hbar k}{m}$. (e) What is the mean free path of an electron near the fermi surface, based on the collision time calculated in (b)?

Required information The voltage across a 8.00 H inductor is given by v₁ = 4t and iL(-0.1) = 100 μΑ (assuming current is defined consistent with the passive sign convention). Calculate the current at t = 0 s. (Round the final answer to three decimal places.) (Include a minus sign if necessary.) The current at t = 0 s is 1.11 mA.

Step 4/4 Simplify the numerator. $-8\left(\left(\sqrt{11} + \frac{5}{14}\right)x^{\sqrt{11} + \frac{-9}{14}}\right)$ Move the negative in front of the fraction. $-8\left(\left(\sqrt{11} + \frac{5}{14}\right)x^{\sqrt{11} - \frac{9}{14}}\right)$ Simplify. $x^{\sqrt{11} - \frac{9}{14}}\left(-8\sqrt{11} - \frac{20}{7}\right)$ Final answer Differentiate using the Power Rule, $\frac{d}{dx}[x^n] = nx^{n-1}$. $x^{\sqrt{11} - \frac{9}{14}}\left(-8\sqrt{11} - \frac{20}{7}\right)$ Was this solution helpful?
