Q1. Assume after charging a 4.80 microF capacitor to 5 V you connect it to the second uncharged capacitor of 15 microF. What voltage will you voltmeter read across the second capacitor after repeating charge sharing process two times? State the answer with one decimal place.
Q2. At one instant a bicyclist is 60m due east of a park's flagpole, going due south with a speed of 15 m/s. Then 25 s later, the cyclist is 35m due north of the flagpole, going due east with a speed of 20m/s. For the cyclist in 25 s interval, what are (a) magnitude and (b) direction of the displacement, the (c) magnitude and (d) direction of the average velocity and (e) magnitude and (f) direction of the average acceleration?

A 65.0 kg human sprinter can accelerate from rest to 10 m/s in 2.90 s. all through the same interval, a 33 kg greyhound can accelerate from rest to 20 m/s. calculate (a) change in kinetic energy and (b) average power output for each.
David is driving a steady 21.0 when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.70 at the instant when David passes. How far does Tina drive before passing David.
When these two wires are connected in equivalent to the same battery, describe the reasoning of the steps that allow you to find out which of these wires will consume the greater amount of power by warming up and dissipating this energy as heat.
