Exploding shoes. the rain-soaked shoes of a person may explode if ground current from nearby lightning vaporizes the water. the sudden conversion of water to water vapor causes a dramatic expansion that can rip apart shoes. water has density 1000 kg/m3 and requires 2256 kj/kg to be vaporized. if horizontal current lasts 2.09 ms and encounters water with resistivity 172 ω·m, length 15.2 cm, and vertical cross-sectional area 16.7 × 10-5 m2, what average current is required to vaporize the water?

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
