Flying Circus of Physics 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 2.26 ms and encounters water with resistivity 154 Q-m, length 14.0 cm, and vertical cross-sectional area 15.2 x 10-5 m², what average current is required to vaporize the water?

Energetic particles, such as protons, can be detected with a silicon detector. When a particle strikes a thin piece of silicon, it creates a large number of free electrons by ionizing silicon atoms. The electrons flow to an electrode on the surface of the detector, and this current is then amplified and detected. In one experiment, each incident proton creates, on average, 34,000 electrons; the electron current is amplified by a factor of 100; and the experimenters record an amplified current of 3.5 μA. How many protons are striking the detector per second?
A solid steel wire has a cross-sectional area of 8.05 x 10-6 m2 and is carrying a constant current of 15.0 A. The density of the wire is 8.05 g/cm3 and the material has a molar mass of 54.97 g/mol. Calculate the drift speed (in mm/s) of the electrons in the wire for the amount of current given. You can assume that each molecule of steel in the wire contributes one free electron of charge.
