[4/9, 1:18 PM] Qevoh: Solid State Physics

a) Solid gold has a density rho=19.3 g/cm^3 and a molar mass M=197grams/mole. Calculate the center-to-center distance between gold atoms in the Face-Centered-Cubic structure of solid gold.

b) Calculate the Fermi Energy Ef (epsilon sub fermi) of gold in eV.

c) At T=0 determine the energy e-sub-one half e(1/2) such that half the conduction electrons in gold have more than this energy.

Write a code in MATLAB that uses Euler's method to solve the following equation, +i mg kvz = m, with the initial conditions that, to = 0, yo = 0 (consider \"y\" increases downwards) and vo = O (the paratrooper parts from rest). The program must generate graphs of a vs. t; vvs. t, and y vs. t, indicating the variables on the axes and their units Question 22 4 pts A physics professor takes a tumble down a hill. Model a physics professor as a solid cylinder of radius r =115 cm and weight 900 N. The professor starts from rest and rolls without slipping down the steep hill. The hill is roughly a 30.0 degree incline (measured from the horizontal) that is 10.0m long (along the hill). The moment of inertia of a solid cylinder is - MR- GEOMETRY HINT: THE HEIGHT OF THE INCLINE WOULD THEN BE (10.0 m)sin(30") - 5.0m In an attempt to save the physics professor, a few dedicated physics students set up a device to bring said professor to a gentle stop at bottom of the hill. What is the net work the device must do in order to bring them to rest? (Hint, you don't have to successfully complete (a) or (b) to do this part, just apply a couple of fundamental principles)
