Question

During a lightning flash, there exists a potential difference of Vcloud ? Vground = 1.7 109 V between a cloud and the ground. As a result, a charge of -15 C is transferred from the ground to the cloud. (a) How much work Wground-cloud is done on the charge by the electric force? Is It Negative Or Positive ? (b) If the work done by the electric force were used to accelerate a 1100-kg automobile from rest, what would be its final speed? (c) If the work done by the electric force were converted into heat, how many kilograms of water at 0

Explanation / Answer

Wground–cloud = +39 ? 10^9 J. vf =_8,421._ m/s: that's eight thousand four hundred & twenty one m =_93,300. kg: that's ninety three thousand, three hundred.
