A certain pump can exert a negative gauge pressure of 7.0 kPa. It is used to suck a liquid out of a bucket up a thin pipe. A 7.7 m column of the liquid exerts a pressure of 100 kPa. To what maximum height (in m) can the liquid be sucked up the pipe by this pump? Enter a number with two digits behind the decimal point. A pump is supposed to remove a liquid of density 1.4 times the density of water from the bottom of a deep hole by sucking the liquid up a pipe. What is the maximum depth the hole can have for this to have a chance of working? 0 ~10.3 m 0 ~73.6 m 0 This will not work. The pump has to push the liquid up the pipe. 0 ~144 m 0 ~5.1 m You are blowing soap bubbles. A small and a large soap bubble stick together. The smaller soap bubble seems to put a dent into the bigger one. Why? O This is just an optical illusion. The common interface of the bubbles is flat. 0 The two bubbles have the same surface tension, but the pressure inside the small bubble is larger than inside the big bubble. C) The large bubble has a bigger surface tension and therefore pulls on the small bubble. Q The pressure in the large bubble is higher than in the small bubble, and so the surface has to compensate for this
