Question1

A creamy salad dressing is completed of heavy cream, corn oil, and vinegar (as well as a pinch of dry mustard, salt and pepper). You set 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 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 layer 2.000e-2 m tall, what is the gauge pressure at the bottom of the jar?
