Question : When a ship enters the sea from a river:
Option 1: it rises a little
Option 2: it sinks a little
Option 3: it remains at the same level
Option 4: it rises or sinks depending on the material its made of
Correct Answer: it rises a little
Solution : The correct option is it rises a little .
A ship rises slightly as it exits the river and enters the sea. Due to the salts that are dissolved in saltwater, it is denser than river water, which is why this occurs. Because of this, the buoyant force of saltwater on the ship is larger than that of river water. The weight of the fluid displaced by the item is equal to the buoyant force, which is the upward force applied to an object submerged in a fluid.
