During a lightning flash, there exists a potential difference of Vcloud−Vground = 1.1 109 V between a cloud and the ground. As a result, a charge of -16 C is transferred from the ground to the cloud.(a) How much work Wground-cloud is done on the charge by the electric force?
—Select— – + —Select— N/C V/C V J
(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?
—Select— m m/s2 m/s
(c) If the work done by the electric force were converted into heat, how many kilograms of water at 0°C could be heated to 100°C?
Wground−cloud =
—Select— J V kg C
