Juan and kuri are on a carousel. juan is closer to the center of the carousel than kuri. which statement describes their tangential speeds? a. juan and kuri move the same distance in one revolution, but juan completes the revolution in less time and has a higher speed. b. juan and kuri complete one revolution in the same time, but juan travels a shorter distance and has a lower speed. c. juan moves a shorter distance in less time than kuri, but their speeds are the same. d. juan and kuri complete one revolution in the same time, so they have the same speed.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
