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 333kJ/kg to be vaporized. If horizontal current lasts 2.00 ms and encounters water with resistivity 150Ω ∙ m, length 12.0 cm, and vertical cross-sectional area 15 x 10-5 m2, what average current is required to vaporize the water?
