question 63

Multiple Choice

A cone with height h = 15.0 cm and bottom area of 7.85 × 10-3 m2 is placed in the container filled with seawater ρ\rho SW = 1030 kg/m3) and oil ρ\rho OIL = 790 kg/m3) so that the bottom of the cone is in seawater and its tip is in oil. What is the average density of the cone if the line between the fluids crosses through the midpoint between the bottom and the tip of the cone?
