Problem 14.10: Water-oil mixture

Please wait for the animation to completely load.

The animation is color coded as follows: Blue is water, red is oil, and brown is a wood block initially floating at the interface. A pump, which starts at t = 1 s, removes the oil. Which animation is physical? (In other words, which animation obeys the laws of physics?) Explain. Restart.
