An insulated 40 ft^3 rigid tank contains air at 50 psia and 120Β°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14ΟΟ΅0. d)the ball will oscillate along the z axis between z=d and z=βd in simple harmonic motion. what will be the angular frequency Ο of these oscillations? use the approximation dβͺa to simplify your calculation; that is, assume that d2+a2βa2. express your answer in terms of given charges, dimensions, and constants
