Araindrop of mass 0.5 * 10^-4 kg is falling verctically under the influence of gravity. the air drag on the raindrop is fdrag = 0.2 * 10^-5 v^2, where v is the speed of the raindrop. find the displacement of the ain drop after 3 second, assume the raindrops starts from rest and use 10m/s^2 for the acceleration of gravity

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?
