How do you think the liquid density affects the buoyancy of objects placed in the liquid?

If an object that is put in a fluid weighs more than the weight of the fluid it displaces, it will sink. Buoyancy is then, directly related to the weight, or density, of the fluid. A more dense, or heavier fluid will then have the ability to “float” heavier objects.

D. most models represent a real world object in a simpler way

It’s the energy source of stars
