Lewis has two spheres made of different substances. Sphere A has a volume of 19.4 cubic centimeters and a mass of 24.0 grams. Sphere B has a volume of 17.0 cubic centimeters and a mass of 13.6 grams. Lewis knows that the density of water is 1.0 grams/cubic centimeter. If Lewis places both spheres in a tub of water, which will float?

Einar sees alexandra every day across the room in his history class but has never talked with her. einar likes the way alexandra looks, including the way she dresses and how she wears her hair. he's even more attracted to her apparent intelligence and the way she handles herself in class discussions and during interactions with the instructor. he'd like to know more about her, so he asks one of his friends about her. einar, using a passive strategy to gain information about her, is probably in the preinteraction awareness stage of any relationship that might develop between them. t/f
