Question

Difference between the floating of an empty ship and a cargo loaded ship​

Answer 1

Answer:

The amount of water displaced by the ship. As you load it, you displace air inside the ship (a gas and relatively speaking not very dense) with solids (relatively speaking much denser - I know how it feels!). Thus, the weight of the ship increases, so it moves lower in the water, displacing a larger volume of water

Answer 2

The loaded ship will weigh more. Thus it will sink down farther in the water in order to displace that much more water so that it continues to float.

One complication is that a light (ie empty) ship might take on ballast (ie water in tanks down low) to improve its stability. So the ship when light might not ride as high as it otherwise would.
