A family builds a home on a small rise near a stream during a period of normal rainfall and gets its water from a well drilled into the zone of saturation (like the one shown in Fig. 14.6). (a) During an extended drought the water table will drop to the level shown by the blue line in Figure 14.6. What effect will this have on the local pond and stream? (b) How will the change in water table elevation affect the family? (c) What do you suggest they could do to remedy this problem? Historical records show that during abnormally wet years, the water table has risen as high as the elevation shown by the yellow line in Figure 14.6. (d) What effect will this have on the stream and pond? (e) What effect will this have on the family's home? based on the computer output above, which of the statements below is false? responses the price of the vehicle would be predicted to decrease by approximately $81.00 for every 500 miles driven. the price of the vehicle would be predicted to decrease by approximately $81.00 for every 500 miles driven. the price-intercept has a logical interpretation in context, as $38,257 would be the price of a vehicle that was new (had never been driven). the , price, -intercept has a logical interpretation in context, as $38,257 would be the price of a vehicle that was new (had never been driven). 66.4% of the variability in vehicle price is explained by the number of miles the vehicle is driven. 66.4% of the variability in vehicle price is explained by the number of miles the vehicle is driven. the correlation coefficient is r at the data layer, entitlement can limit access to specific areas of the file structure, or even individual files. true or false?

Which methods would increase the rate? Select all that may apply. Select 3 correct answer(s) decreasing the pressure so that a solid dissolves in the solution Oshaking/stirring the mixture causing an increase in the rate of dissolution O grinding the solute to increase the surface area increasing the pressure so that a solid dissolves in the solution increasing the temperature in order to increase molecule collisions Phosphoric acid is a triprotic acid ( Ka1=6.9103 , Ka2=6.2108 , and Ka3=4.81013 ). To find the pH of a buffer composed of H2PO4(aq) and HPO24(aq) , which p Ka value should be used in the HendersonHasselbalch equation?p Ka1 = 2.16p Ka2 = 7.21p Ka3 = 12.32Calculate the pH of a buffer solution obtained by dissolving 10.0 g of KH2PO4(s) and 20.0 g of Na2HPO4(s) in water and then diluting to 1.00 L.pH= the maximum in precipitation and cloudiness that hovers near the equator all year round is associated with the... changes in the number of individual chromosomes rather than in the number of complete sets of chromosomes is a condition called explain two similarities and two differences between monosaccharides, disaccharides, and polysaccharides. be as specific as possible, and include an example of each. A cost that will not be affected by the later decisions is termed a(n):a. historical costb. differential costC. sunk costd. replacement cost Divide. Write your answer in simplest form. 1/5 4 ___ are used to coordinate activitires betweeen the top and bottom of an organization and are designed primarily for control of the organiation which is more basic 0.1 m naf or 0.1 m nano3 One industry has four firms and their market shares are as follows: C1: 40% C2: 30% C3: 19% C4: 11% The Herfindahl-Hirschman index (HHI) of this industry is If C2 and C4 merge, the new HHI of this industry will beIf one can justify expanding the definition of the industry to include more firms and these firms are about the similar size as C1, C2, C3, C4 here, then HHI can be smaller.
