You can tell how much cargo a ship has on board by looking at how it floats. When the ship is full, it floats low in the water because the cargo increases the ship's
A. average density so that it must displace more water to stay afloat.
B. volume so that it takes up more room in the water.
C. momentum so that more water is needed to balance that momentum.
D. moment of inertia so that the water needs more kinetic energy to keep the ship afloat.
