Oil with a surface tension of 0.01 n/m is trapped in a bed of material with permeability of 1x10^-10 m^2 and a length of 150 m. we want to push the oil out of the bed by pumping in an extraction fluid (neglect the properties of this fluid) at 12000 kpa. when the oil stops coming out, what fraction of oil will be left in the bed?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.

Which process does not require the presence of a physical substance in order to transfer heat? air in the atmosphere is heated by the ground. this warm air then rises, and cooler air falls. this is an example of what type of process? how is conduction different from radiation?
