Learning Goal: To practice Tactics Box 13.2 Finding whether an object floats or sinks. 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 pr is larger than, smaller than, or equal to the object's average density - These conditions are summarized in this Tactics Box. TACTICS BOX 13.2 Finding whether an object floats or sinks Y Part A Pull = Submit Part B An object sinks if it weighs more than the fluid it displaces, that is, if its average density is greater than the density of the fluid Pars > Pt. Ice at 0.0°C has a density of 917 kg/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, Pa? Express your answer in kilograms per meter cubed to three significant figures. VAE Submit Object sinks " d Part C Request Answer Once the ice cube melts, what happens to the liquid water that it produces? View Available Hint(s) C? The liquid water sinks to the bottom of the container. The liquid water rises to the surface and floats on top of the oil. The liquid water is in static equilibrium at the location where the ice cube was originally placed. Object floats 42 An object rises to the surface if it weighs less than the fluid it displaces, that An object hangs motionless if it weighs exactly the same as the fluid it displaces-that is, if its average density equals the density of the fluid is, if its average density is less than the density of the fluid: Pang Pt Parz Pr. What happens if some ethyl alcohol of density 790 kg/m³ is poured into the container after the ice cube has melted? Alayer of ethyl alcohol forms between the oil and the water. The layer of ethyl alcohol forms at the bottom of the container. The layer of ethyl alcohol forms on the surface. Object has neutral buoyancy A
