Answer 3

what do you think? :P

whats archimedes principle?

Answer 4

Okay, so by logic. I'm thinking the answer would have to be C, Decreasing. Because, A,
Increases, logically doesn't make sense. Buoyancy is the ability to float, right? So if it sinks, the buoyancy would decrease, right? I think the same should go to B. For D, does the shape really matter in this case? lol Sometimes, the shape does matter, but in this case, I don't think it does...

Answer 5

While there is still some of it above the water, sinking puts a greater volume beneath the surface, increasing the buoyant force.

Once wholly submerged, the volume remains the same and thus the buoyant force does not change further.
