Two balls of equal masses, one at rest, the other moving with a speed V directly toward the other. Assuming the collision is partially elastic with a coefficient of restitution of 0.8, what final velocities, in terms of V, would the two balls end up with

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.
