SUMMARY
The apparent weight of a submerged rock can be calculated using the formula: Apparent Weight = mg - ρ_water * V * g, where mg is the weight of the rock in air, ρ_water is the density of water, V is the volume of the rock, and g is the acceleration due to gravity. For a rock weighing 58 N with a volume of 1.8 * 10^-3 m^3 submerged in water, the buoyant force is equal to the weight of the displaced water. Additionally, for a rock weighing 57 N with a volume of 2.3 * 10^-3 m^3 submerged in a liquid with double the density of water, the apparent weight can be recalculated using the same principles, adjusting for the increased buoyancy from the denser liquid.
