Question

A ship is floating in a canal lock. If cargo is loaded into the boat from the shore, what will happen to the water level? Choose one answer only. The water level will rise. The water level will remain the same. The water level will fall. Any of these are possible, depending on the amount of cargo. Suppose the cargo was thrown into the water in the lock rather than loaded into the boat. If the cargo sinks, how much will the water level change compared to if it had been loaded into the ship? Choose one answer only. The water level changes more. The water level changes by the same amount. The water level changes less. Any of these are possible, depending on the amount of cargo.
