Three identical garden hoses (same length and same inner diameter) are attached to three identical faucets which supply water at the same pressure to all three hoses. All three hoses are open to the atmosphere at their other ends. Hose A runs along a level path at the elevation of the faucet. Hose B runs down a hill and its free end is 10 ft below the level of the faucet. Hose C runs up and over a high wall, but its free end is back at the elevation of the faucet. Required:
How do the flow rates through the three hoses compare? Justify your answer. Make certain to explicitly show the pair of points you are applying the model between; this should be your first step in solving these problems. Please use the Bernoulli equation to solve:

In the future, people will only enjoy one sport: electrodisc. in this sport, you gain points when you cause metallic discs hovering on a field to exchange charge. you are an electrodisc player playing the popular four disc variant. the disks have charges of qa = −8.0 µc, qb = −2.0 µc, qc = +5.0 µc, and qd = +12.0 µc. (1) you bring two disks together and then separate them. you measure the resulting charge of these two disks and find that it is +5.0 µc per disk. which two disks did you bring together? (a) a and b (b) a and c (c)a and d (d)b and c(e) b and d (f) c and d. (2) you bring three disks together and then separate them. you measure the resulting charge of these three disks and find that it is +3.0 µc per disk. which three disks did you bring together? a, b, and c (a) a, b, and d (c) a, c, and d (d) b, c, and d. (3) given the resulting charge of each disk measured in (b) is +3.0 µc, how many electrons would you need to add to a disk of this charge to electrically neutralize it? electrons
