7. Determine the acceleration of the system and the tension in each cable. The inclined plane is smooth (negligible friction), and the coefficient of kinetic friction between the horizontal surface and block C is 0.2. Assume that the mass and friction at both pulleys is negligible. Solve using the inertia method. (10 Points)

a. Elements from Group V of the periodic table can potentially act as n-type dopants for silicon. b. n-type dopant atoms turn into positive ions in the semiconductor lattice. c. Fermi level is the energy level at which the highest concentration of free electrons exist. d. Carrier mobilities in semiconductors drop at high doping concentrations due to interactions with ionized dopant atoms. e. Gallium (Ga) is below Aluminum (Al) in the periodic table of the elements, therefore, it is expected that GaAs has a wider bandgap compared to AlAs. f. Wider bandgap semiconductors generally have higher number of intrinsic carriers. g. Instrinsic semiconductors cannot conduct electricity at all. h. If temperature increases so that the intrinsic carrier concentration reaches and surpasses doping concentration, extrinsic semiconductor turns into intrinsic semiconductor. i. LEDs cannot be made of silicon because silicon has a smaller band gap compared to GaAs. j. GaAs has a larger band-gap compared to silicon therefore it can absorb a wider range of different wavelengths present in the sunlight.
