A dc motor with its rotor and field coils connected in series has an internal resistance of 3.2 Ω. When running at full load on a 120-V line, the emf in the rotor is 105 V. Part A What is the current drawn by the motor from the line? Express your answer using two significant figures.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
