Two identical point charges (q = +7.25 10-6 C) are fixed at diagonally opposite corners of a square with sides of length 0.485 m. A test charge (q0 = -2.60 10-8 C), with a mass of 7.05 10-8 kg, is released from rest at one of the empty corners of t
Determine the cycle's coefficient of performance. Use constant specific heat at room temperature. Consider problem 1 again but this time the compressor and turbine have isentropic efficiencies of 87% and 92% respectively.
Suppose that from t = 0 to t = 4.9 s, the elevator ascends at a constant speed of 10 m/s. Its speed is then steadily reduced to zero during the next 3.2 s, so that it is at rest at t = 8.1 s. Describe the reading of the scale during the interval 0
Derive an expression for the steady-state temperature, T_b, at the base of the rod (x=0). The exposed portion of the rod should be modeled as an infinitely long fin.
Calculate the friction force on a walking 75.0 kg astronaut carrying a 44.0 kg instrument pack on the moon if the coefficient of kinetic friction at her hip joint is 0.0050. (Recall that approximately 65 of the body weight is above the hip.)
