What does negative buoyancy mean?
The object will sink
What principle states that the magnitude of the buoyant force on an object is equal to the weight of the fluid it displaces?
Archimedes principle
Why did only the Diet Coke Float
It is less dense than the regular Coke due to the lack of sugar content
