Get the Gizmo ready: Place the overflow cup under the faucet. Fill it until water starts to flow out of the spout. Place the 250-mL beaker next to the overflow cup so that the spout of the overflow cup is over the beaker. (If necessary, empty the beaker into the sink.) Measure: Place the sphere into the overflow cup, causing water to pour into the beaker. Empty the beaker into the 50-mL graduated cylinder. Place the magnifier over the waterline. What is the volume of water in the graduated cylinder?

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
