ARCHIMEDES' PRINCIPLE:

Archimedes' principle states that the upward buoyant force on an object in a fluid is equal to the weight of the fluid it displaces
Water's density = 1000 kg/m^3. Cylinder's high H = 2 m
Change density of the cylinder to see what's its submerged high h?
Density: kg/m^3 Submerged high h = : m
Can you figure out the relationship between H, h, cylinder's density and water's density? Oscillate
