An isolated conducting rod of length 8.00 cm is oriented parallel to the x-axis. It moves in the +y-direction at 3.90 m/s in the presence of a uniform magnetic field of magnitude 0.600 T that points in the -z-direction. Find the magnitude of the motional emf in the rod. Express your answer with the appropriate units.

An astronaut on the moon throws a baseball upward. the astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 3030 ft per sec. the height s of the ball in feet is given by the equation s equals negative 2.7 t squared plus 30 t plus 6.5s=−2.7t2+30t+6.5, where t is the number of seconds after the ball was thrown. complete parts a and b.
