Maria makes a graphic organizer to compare open, closed, and short circuits. she adds the labels shown. label 1: current flows in the circuit. label 2: this forms when a bulb burns out. in which region should she place each label? label 1: z label 2: x label 1: y label 2: w label 1: x label 2: y label 1: y label 2: z

A248-g piece of copper is dropped into 390 ml of water at 22.6 °c. the final temperature of the water was measured as 39.9 °c. calculate the initial temperature of the piece of copper. assume that all heat transfer occurs between the copper and the water. remember, the density of water is 1.0 g/m
