Objects that are dropped into a swimming pool need to be removed. These objects include foam cups, keys, and coins. Which of the following explains a useful method for removing some of these objects?
The keys and coins are less dense than water, so they can be easily picked up off the bottom of the pool by divers.
The foam cups have the same density as water, so they can be crumbled up for removal by the pool filter.
The foam cups are less dense than water, so they can be fremoved from the surface with a pool cleaning net.
The keys and coins have the same density as water, so they can be washed away when the pool is drained.
