Learning Goal: To practice Tactics Box 15.2 Finding whether an object floats or sinks. If you hold an object underwater and then release it, it can float to the surface, sink, or remain 'hanging' in the water, depending on whether the fluid density at is larger than, smaller than, or equal to the object's average density rho avg These conditions are summarized in this Tactics Box. PART A Ice at 0.0degree C has a density of 917kg/m3 A 3.00 cm3 ice cube is gently released inside a small container filled with oil and is observed to be neutrally buoyant. What is the density of the oil, rho o? Express your answer in kilograms per meter cubed to three significant figures. rho oil = kg/m3

Explanation / Answer

density of oil = density of ice cubbe (neutrally buoynat)

==> density of oil = 917 kg/m3
