1. If an economist says the higher the price of oranges, the fewer oranges individuals will buy, ceteris paribus, this means that: A.individuals dont like high-priced oranges. B.as the price of oranges rises, individuals preferences change and they no longer like oranges as much as they once did. C.as the price of oranges rises, individuals preferences do not change, nor does anything else, but individuals buy fewer oranges in response to the higher price of oranges. D.the higher the price of oranges, the fewer oranges individuals will buy, assuming that people have economic motives. 2. Labor is a resource that is necessary to produce many goods. If the price of labor falls, says the economist, the price of goods will soon follow. How does this work? A.If the price of labor falls, the supply of goods rises, and the prices of those goods fall. B.If the price of labor falls, the quantity supplied of goods rises, and the prices of those goods fall. C.If the price of labor falls, the demand for goods falls, and the prices of those goods fall. D.If the price of labor falls, the demand for goods rises, and the prices of those goods fall. 3. An economist says, Technological advances have the power to lower the prices of many of the goods we buy. Here is how this works: A.technological advances lead to lower demand, which leads to lower prices. B.technological advances lead to greater supply, which leads to lower prices. C.technological advances lead to greater quantity supplied, which leads to lower prices. D.technological advances lead to lower taxes, which lead to greater supply, which leads to lower prices.

Late assignments, less than one week late, will incur a penalty of 20%. Assignments handed in more than one week late will not be assessed and a nil mark will be recorded. Please feel free to ask if anything (in this assignment) is not clear to you. This assignment is 17.5% of the total marks, and is due on 22nd May in the classroom to B Mahmood. Question 1: Open Channel Flow a) Consider, there is a trapezoidal open channel and the depth of flow on the channel centerline is 3.3 m. The bottom and top widths of the channel are 4.0 m and 17.2 m, respectively. (i) Compute the value of the wetted perimeter, the hydraulic radius, and the hydraulic mean depth (i.e. Area/Top width). (3 marks) (ii) If the optimum hydraulic section for a trapezoidal channel is half of a hexagon prove that the top width of the channel is 2.309 D, where D is the centerline depth. (3 marks) (iii) If D is 3.3 m then what should be the dimensions and side slopes of the channel to obtain the maximum discharge? (2 marks) b) The expected discharge from an urban subdivision is (2.5 m3/s + F/10) and the allowable gradient to the outfall is 1 in 850. Two design possibilities are to either construct a concrete-lined open channel, or to carry the flow through a concrete pipe. Mannings (n) in each case is 0.012. (i) Calculate the dimensions of a trapezoidal channel with side slopes at 450 and a bottom width twice the depth. (4 marks) (ii) For the concrete pipe design, calculate the pipe diameter if it is to be designed running just about full. (4 marks) c) Explain why it is essential for an engineer to know whether the flow is subcritical or supercritical when designing an open channel and a bridge that will have its abutments in the channel.

Sue and Sue (2013) illustrated similari

Sue and Sue (2013) illustrated similarities and differences among people, and the powerful influence of perceived group membership on how we view others and how we view ourselves with this saying: “All individuals, in many respects, are (a) like no other individuals, (b) like some individuals, and (c) like all other individuals” (p. 41). Considering the article you read for your specialization area, discuss the impact of group membership or memberships as they relate to the population you read about and your specialization area.
