Q1. Assume the temperature T in F above the earth's surface is given by t (h) =-3.6(h) + 68 where h is height (in thousands of feet)
Find out temperature at a height of 10,000 feet?
Find out the height if the temperature is -58F
Q2. If 3.43×10^8 electrons flow through the ground wire to Earth and the ground wire is then removed, what is the net charge on the electroscope?
