For a material to float on the surface of water, the material must have a density less than that of water (1.0 g/ml) and must not react with the water or dissolve in

it. A spherical ball has a radius of 0.50 cm and weighs 2.0 g. Will this ball float or

sink when placed in water? (Note: Volume of a sphere = 4/3(pi)(r^3)

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
