Ricardo and jane are standing under a tree in the middle of a pasture. an argument ensues, and they walk away in different directions. ricardo walks 28.0 m in a direction 60.0 ∘ west of north. jane walks 16.0 m in a direction 30.0 ∘ south of west. they then stop and turn to face each other.(a) what is the distance between them? (b) in what direction should ricardo walk to go directly toward jane?

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?
