Textbook Question

Chapter 1.4, Problem 51P

An accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of radioactive material present is 15 su (safe units), and 5 months later it is still 10 su.

(a) Write a formula giving the amount A (t ) of radioactive material (in su) remaining after t months.

(b) What amount of radioactive material will remain after 8 months?

(c) How longâ€”total number of months or fraction thereof will it be until A = 1 su . so it is safe for people to return to the area?

The liquid-liquid extraction process carried out at the Electrochemical Materials Laboratory involves the extraction of nickel (Ni) from the liquid phase into an organic phase. Data from laboratory experiments are given in the table below. Ni phase cair, a (gr/l) 2 2,5 3 Ni phase organik, g (gr/l) 8,57 10 12 Assume that a is the amount of Ni in the liquid phase, and g is the amount of Ni in the organic phase. Quadratic interpolation is used to estimate the value of g, which is given by the following formula: g = x1a? + x2a + x3 a. Find three simultaneous equations based on the data given by the experimental results. b. Use the Gauss Elimination method to get the values of x1, x2 and x3 and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase. c. Use the LU Decomposition method to get the values of x1, x2 and x3. and then estimate the amount of Ni in the organic phase, if 2.3 g/l of Ni is available in the liquid phase.

Limits 15, 128 MB We all know about the recent flood in Sylhet. Every area of Sylhet can be expressed with a number. If there are n number of areas in Sylhet then they can be expressed as 1, 2, 3...n-1,n. Where the area is located after the (1) area. Volume of each area of Sylhet is 1 meter. A few dams have been constructed in certain areas in Sylhet. Each dam is pre-planned to be built at a certain height so that the flood water cannot completely inundate the city Flood water will enter through the 1, area. The height of the dam in the area is B, meter. If the water level in area i is greater than B meter then the remaining water will flow in (i+1), area. Due to the good communication system of Sylhet, people can move from one area to another before any danger Sylhet is the city of rain. Every area has some tall buildings built to deal with the flood problem. The building in the fen area has H, floors and each floor has a height of 1meter. Due to the weather forecast people can know…
