During a lightning flash, there exists a potential difference of V cloud V ground = 1.1 10 9 V between a cloud and the ground.
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
