6. In another experiment, the students drop a small object of an unknown subst- column. If the object floats in a position located above the piece of coal, which of likely true? a. The density of the object is greater than 0.92 g/cm³. b. The density of the object is greater than 1.20 g/cm³. c. The density of the object is greater than 1.33 g/cm³. d. The density of the object is greater than 1.42 g/cm³.

Please solve

A plastic sphere floats in water with 54% of its volume submerged. This same sphere floats in glycerin with 62% of its volume submerged. Determine the density of the sphere (kg/m3). Numerical Answer only

3. A rectangular block of volume Vo is placed in a tank of water and sinks to the bottom. Describe the buoyant force acting on this block. What could be a possible density of the block?   a. The buoyant force equals the weight of a volume of water of Vo, 5.00 grams/cm3   b. No buoyant force acts on the block, 0.0500 grams/cm3   c. The buoyant force equals the weight of a volume of water of Vo, 0.450 grams/cm3   d. The buoyant force equals the weight of a volume of water of Vo, 0.100 grams/cm3   e. The buoyant force equals the weight of a volume of water of one-half of Vo, 0.333 grams/cm3
