A creamy salad dressing is made up of heavy cream, corn oil, and vinegar (as well as a pinch of dry mustard, salt and pepper). You put the cream, oil, and vinegar in a glass jar. The density of the cream is 994 kg/m3, the oil 880 kg/m3, and the vinegar 1000 kg/m3. The salad dressing liquids separate into three layers.
(a) What is the order of the layers from top to bottom?
(b) If the cream layer is 2.20×10?2 m tall, the oil layer 2.80×10?2 m tall, and the vinegar layer1.000e-2 m tall, what is the gauge pressure at the bottom of the jar?
