The population of the world is approximately 7.7 billion people. a. The land area of Burke County is 515 square miles. If the entire world’s population were put into Burke County, determine the number of people that would be in each square mile. (Round to the nearest whole person) {#1}b. Based on the fact that there are approximately 28 million square feet in each square mile, does your answer to question 6 even seem reasonable? In other words, could the entire population of the world actually fit inside the borders of Burke County without people being stacked on top of other people? (Round to the nearest tenth)Each person would have {#2} square feet of space to move around. Is this reasonable? {#3}

It has an energy gap EG = [eg] eV, effective masses mn* = [mn1] m0 and mp* = [mp] m0, where m0 is the free electron mass = 9.11 x 10-31 kg. For 2 points calculate the position of the intrinsic Fermi level. For another 3 points find the electron and hole concentrations n0 and p0 when EC – EF = [ecf] eV. Constants:   kb = 1.38 x 10-23 J/°K;           q = 1.602 x 10-19 C; h = 6.626 x 10-34 J-s;
