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? o the bobber and lure are more dense than the water. o the bobber and lure are less dense than the water. o the bobber is more dense than the water, and the lure is less dense than the water. o the bobber is less dense than the water, and the lure is more dense than the water.
Answer
Explanation:
Step1: Recall density - buoyancy relationship
Objects less dense than water float, and those more dense sink.
Step2: Analyze the bobber
The bobber floats on the surface of the water, so it is less dense than water.
Step3: Analyze the lure
The lure sits below the surface, which means it is more dense than water and sinks.
Answer:
The bobber is less dense than the water, and the lure is more dense than the water.
