3. (6 points) In the Prefixes for Powers of 10 table In the Power of ten column, which value is not like the others? For values LARGER than 10, which Abbreviation is not like the others? For values SMALLER than 10°, which Abbreviation is not like the others?
Estimate the order of magnitude of the length, in meters, of each of the following. (a) a mouse O 10-3 m O10-1 m O 100 m O 102 m (b) a pool cue O10-2 m O10-1 m O 100 m O 101 m (c) a basketball court O between 10° m and 101 m O between 101 m and 102 m O between 102 m and 103 m (d) an elephant O 100 m 101 m 102 m
6. The new mini-laptop computers can deliver as much computing power as machines ten times their size, but they weigh in at less than 3 lb. Experts predict they will soon replace their traditional 6- to 8-lb older laptop brothers as tech computer industry continues its relentless quest for smallness. If the standard deviation of the weight of all mini-laptops is 0.4 lb, how large a sample would be needed to estimate the population mean weight if the maximum error...

850 Question #2 (4 pts.) Estimate the number of 3 5/8" x 3 5/8" x 7 5/8" bricks to be used in the wall at right. The mortar joints are 3/8" in all directions. Also, estimate the volume of mortar used if applied at a rate of 2 per 25 ft of wall, and the number of corrugated masonry ties to the structural wall behind if the ties are placed at 20" on center. 14'-0"
3. For matrix 2 2 3 x Power me+hod A 2 4 5 L3 5 7 use the power method to estimate the eigenvalue of greatest absolute value and a malized eigenvector. Note that I'm not asking what Wolfram Alpha or Matlab or whatever says the answer is. I want to know how the power method acts. Does it converge quickly? Slowly? Not at all?

3. One big historical use for wind power was water pumping. Estimate the power output for a typical large Dutch Windmilil at 10 meters per second windspeed (see Chapter 1, Fig 1.3). Easiest way would be to estimate the diameter of the unit (use the best clues from the image), calculate the swept area, and assume some efficiency factor FIGURE 1.3 Historical farm windmills at J.B. Buchanan farm near Spearman, Texas. Windmills have since been moved to an outdoor museum...

3) Using an order of magnitude method (Hill), estimate the TCI in year 2006 dollars for a grass-roots plant with 100,000-lb annual production using an order-of-magnitude method based on a 10,000-lb annual production. The plant contains three 1200-ft/min centrifugal fans, five 1500-ft/min centrifugal blowers, seven 100-ft' centrifugal separators, and two 100-ft shell-and-tube heat exchangers. You may assume all materials are carbon steel, the materials handled are primarily solid, and that this plant construction is done fully...
