Question

gerald is fishing. he uses a bobber that floats on the surface to show him if the line is being moved, and a lure that sits below the surface to attract fish. which statement accurately describes the densities of these two items? \bigcirc the bobber and lure are more dense than the water. \bigcirc the bobber and lure are less dense than the water. \bigcirc the bobber is more dense than the water, and the lure is less dense than the water. \bigcirc the bobber is less dense than the water, and the lure is more dense than the water.

Explanation:

An object floats in water if its density is less than water's density, as it displaces a weight of water equal to its own weight. An object sinks below the water's surface (like the lure) if its density is greater than water's density, since it cannot displace enough water to counteract its weight.

Answer:

The bobber is less dense than the water, and the lure is more dense than the water.
