Verified Answer
As a ship enters into a river from sea, one can expect thata)It rises ...
Density of sea water (ρsw) > density of river water (ρrw)
For the same ship, balancing the buoyant force for both conditions,
where h is the depth of ship into the water
For the same ship, balancing the buoyant force for both conditions,
where h is the depth of ship into the water∴ The ship rises up when it enters the sea from a river.

Explanation:
When a ship enters a river from the sea, it experiences a change in buoyancy due to the difference in water density. This change in buoyancy causes the ship to sink a little.
Factors Affecting Buoyancy:
1. Density: The density of water in the river is usually higher than the density of seawater. This is because river water contains sediments, minerals, and other dissolved substances that increase its density. As the ship enters the river, it displaces a volume of water equal to its own weight. Since the density of river water is higher, the ship will displace less water and experience a decrease in buoyant force.
2. Displacement: The shape and size of the ship also play a role in its buoyancy. Ships are designed to displace a certain amount of water based on their size and weight. When a ship enters a river, the depth of the water may change, affecting the ship's displacement. If the river is shallower than the sea, the ship may sink a little to maintain its equilibrium.
3. Weight: The weight of the ship remains constant regardless of the body of water it is in. However, the buoyant force acting on the ship changes due to the difference in water density. As a result, the ship sinks a little to adjust to the new buoyant force.
Conclusion:
In conclusion, when a ship enters a river from the sea, it sinks a little due to the higher density of river water compared to seawater. This change in buoyancy is necessary to maintain the ship's equilibrium and ensure it does not float too high or too low in the water.
