Alana drew diagrams to show how particles in a spoon move before and after the spoon is placed in hot liquid. At left a grid labeled Before of regularly arranged orange balls with large movement lines near each. At right a grid labeled After of regularly arranged orange balls with small movement lines near each. Which best explains how to correct Alana’s error?Make the particles in both diagrams larger. Show more movement in the ""Before"" diagram. Add more particles to the ""After"" diagram. Switch the labels on the diagrams.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
