1. The mass of a piece of ice is 0.530 kg, density of water = 1.00 × 103 kg/m3, and density of ice = 917 kg/m3. What is the buoyant force on the ice floating freely in liquid water? Enter a positive answer if the buoyant force is upward and a negative answer if the buoyant force is downward. 2. The mass of a piece of ice is 0.530 kg, density of water = 1.00 × 103 kg/m3, and density of ice = 917 kg/m3. What is the buoyant force on ice held completely submerged under water? Enter a positive answer if the buoyant force is upward and enter a negative answer if the buoyant force is downward.
