Three cups inverted into water are shown below. Cup 1 has a water level inside that is below the water levelexposed to the atmosphere.
I need help, I don't know how to approach this problem: Three cups inverted into water are shown below. Cup 1 has a water level inside that is below the water levelexposed to the atmosphere. Cup 2 has a water level inside that is above thewater level exposed to the atmosphere. Cup 3 has a layer of oil (which isless dense than water) atop the water level inside of it. Cup 2 and cup 3have the same volume of air trapped in them. All three cups have airtrapped inside of them. Apply the energy density model to each cup so youcan rank the pressures (P1, P2, P3) of the air pockets trapped inside them, from least to greatest pressure.
