A person in a boat floating in a small pond throws an anchor overboard. Does the level of the pond rise, fall, or remain the same?

Expert Answer:

The level of the pond falls.
This is because the anchor displaces more water while in the boat. A floating object displaces a volume of water whose weight is equal to the weight of the object.
A submerged object displaces a volume of water equal to the volume of the object. Because the density of the anchor is greater than that of water, a volume of water that weighs the same as the anchor will be greater than the volume of the anchor.
