Please show all steps and explain your reasoning in detail for parts e, f, & g. Ignore a - d. Thank you. Consider a "2D electron gas". Ne electrons of mass m * confined to a square ofarea A = L2 with zero potential. Take the lowest level to be energy zero. a. What is the total number of states N with energy less than E including spin degeneracy? b. Deduce the energy density of states, defined by D(E) c....
please help step by step phym316 mc 139%. question 4 (25 marks) Consider a metal bar with square cross-section that is 10 cm long and 1 cm wide. A potential difference of 250 V is applied across its ends. It has a resistivity of 10-8 2m and electron density of 6 x 10sm-3 (a) Calculate the relaxation time, T. (b) Calculate the shift in the Fermi surface due to the applied voltage. [51 15] (d) What is the thermal conductivity...
Could someone help me with this question please as I am kinda lost as in how to do these type of questions please explain each step For a wind turbine, derive, from conservation of mass, momentum and energy, the maximum power which can be extracted as a) max 2 where p is the density of air, U is the upstream wind speed, A is the swept area of 16 the wind turbine and Cs the power coefficient. P 27 [11...
Could someone help me with this question please as I am kinda lost as in how to do these type of questions please explain each step a) Draw a diagram of a solar hot water system and discuss the functions of its [5 marks For the solar collector, analyse the solar radiation heat gain and heat losses through different modes of heat transfer. How is the heat transfer rate to the water per unit area of the collector calculated? b)...
