Question

"A piece of iron rests on top of a piece of wood floating in a bathtub. If the iron is removed from the wood, and kept out of the water, what happens to the water level in the tub?"

Answer 1

a. goes down

Step-by-step explanation:

According to Archimedes' principle, the buoyance that iron experiences on the water is a result of upward displacement of water. Once the iron is removed the water level will go down because the weight of the iron that caused the upward displacement have been removed.
