Problem 13.36 Archimedes' principle can be used not only to determine the specific gravity of a solid using a known liquid; the reverse can be done as well. Part A As an example, a 3.50-kg aluminum ball has an apparent mass of 2.50 kg when submerged in a particular liquid: calculate the density of the liquid. ANSWER: kg/m³ Part B Derive a formula for determining the density of a liquid using this procedure. Express your answer in terms of the variables mobject, mapparent, and Pobject . ANSWER: Pfluid =
