Abowling ball encounters a 0.760 m vertical rise on the way back to the ball rack, as the drawing illustrates. ignore frictional losses and assume that the mass of the ball is distributed uniformly. the translational speed of the ball is 4.50 m/s at the bottom of the rise. find the translational speed at the top.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
