An electron is moving through a magnetic field whose magnitude is 9.21 × 10^-4 t. the electron experiences only a magnetic force and has an acceleration of magnitude 2.30 × 10^14 m/s^2. at a certain instant, it has a speed of 7.69 × 10^6 m/s. determine the angle (less than 90°) between the electron's velocity and the magnetic field.

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

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.
