2. Estimating Density A plastic sphere floats in water with exactly half of its volume submerged. When this same sphere is placed in glycerin only 40.0\\% of its volume is submerged. Assume the density of water to be 1.00\\times10^3\\frac{\\text{kg]}{\\text[m]^3]. a. Determine the density of the glycerin. Explain your work. b. Find the density of the sphere. Explain your conclusion
