A wooden boat swims in a bucket of water. A stone figure is put on the boat. The figure falls into the water and sinks to the bottom of the bucket. What happens to the water level?
The water level remains the same because the boat and the figure displace the same volume of water as before.
The water level decreases because the figure only displaces its own volume.
The water level decreases because the boat does not displace volume anymore
The water level increases because the figure displaces more volume.
