Question

As a ship is unloaded, why does it rise higher in the water?

A.The density of the ship and its cargo increases.
B.The mass of the ship and its cargo increases.
C.The density of the ship and its cargo decreases.
D.The buoyancy of the ship and its cargo decreases.
this is science i need help

Answer 1

Because the bouyancy of something also depends on it's weight (mass).

When you unload a ship, less gravity is applied to it (gravity pulls things down), so that is why it rises.

Answer:

B

Answer 2

HEYA!!!

When the ship is unloaded then the weight of the ship decreases, so, the buoyant force required to keep the shipfloating also decreases. ... Thus, the volume of ship below water level also decreases. This makes the ship to rise above water.
