A tank has various objects submerged in water: a metal cube (mass 10 kg, volume 2 m³), a rubber ball (mass 0.5 kg, volume 1 m³), and a glass bottle (mass 1 kg, volume 0.5 m³). Calculate the density of each object and determine which will float and which will sink. Explain why using R.D.
💡 Hint: Calculate density for each object first from mass and volume.
A vessel contains two liquids: oil with a density of 800 kg/m³ and water with a density of 1,000 kg/m³. A solid object with a density of 900 kg/m³ is gently placed in the vessel. Discuss what happens to the object and explain using relative densities.
💡 Hint: Compare the object's density with each liquid's density.
