11. the battery in rebekah's car has gone flat. michael and eddy are push-starting the car. the diagram below shows the
forces applied to the car. the men need to apply enough force to overcome the forces opposing the movement of the
car. the mass of the car is 910 kg.
eddy 400 n
son force
michael 450 n
→ internal friction 530 n
→ friction with road 150 n
draw a free body diagram showing the net forces applying to the car:

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?
