Write two applications of Archimedes' principle.
Figure shows a cork floating on water. Draw the two forces acting on it. Write the names of these forces. Which force is more?
An object floats in water because the buoyant force is equal to the weight of the object. If an object is placed in a liquid denser than water, what happens to the buoyant force?
A cylindrical metal rod with a density of 8,000 kg/m³ and a volume of 0.1 m³ is placed in water. The density of water is 1,000 kg/m³. The rod is partially submerged in water.
A block of metal is submerged in water and experiences an upthrust of 10 N. If the density of the metal is 8000 kg/m³ and the volume of the block is 0.001 m³, calculate the buoyant force acting on the block.
The volume of a 500 g sealed packet is 350 cm³. Will the packet float or sink in a saturated salt solution, if the density of the solution is 1.2 g cm⁻³? What will be the mass of the solution displaced by this packet?
