Two blocks of masses m and m are connected by a string and pass over a frictionless pulley. mass m hangs vertically, and mass m moves on an inclined plane that makes an angle θ with the horizontal. draw a sketch, and if the coefficient of kinetic friction is μk, calculate the angle θ for which the blocks move with uniform velocity. discuss the special case when m = m

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
