Lightning Flash In a given lightning flash, the potential difference between a cloud and the ground is 3.0 x 109 V and the quantity of charge transferred is 29 C. (a) What is the decrease in energy of that transferred charge? 8.7e+10 GJ (b) If all that energy could be used to accelerate a 1000 kg automobile from rest, what would be the automobile's final speed? m/s (c) If the energy could be used to melt ice, how much ice would it melt at 0C? The heat of fusion of ice is 3.33 105 J/kg. kg Section 25.3 Electric Potential
