Graph of velocity versus time with velocity on the y axis from 0 to 25 meters per second and time on the x axis from 0 to 10 seconds. Segment A goes from 0, 0 to 5, 20. Segment B goes from 5, 20 to 10, 20. What was the acceleration during the segment labeled "A"? 4 m/s/s 5 m/s/s 10 m/s/s 20 m/s/s

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
