In 2008/09 the British pound depreciated by approximately 25% on a trade-weight basis after the Bank of England reduced interest rates to a historically low level. In your opinion, did the depreciation in sterling damage the UK economy? What are the consequences of a depreciation? Are exchange rate movements necessarily good or bad for a country? Explain

M1 has a mass of 6.330 kg. It is on a horizontal surface connected by a massless string to a hook where M2 can be increased smoothly. The pulley has a negligible mass & no friction. When M2= 3.266 kg it begins to accelerate downward at a rate of 2.110 m/s2. Calculate u_s - u_k between M1 and the surface.

The general form of a phase diagram is given below. Observe that this phase diagram is divided into three regions by the blue boundary lines similar to the way the interactive phase diagram for CO2 was divided. Compare this general form of this phase diagram with the interactive phase diagram for CO2 and classify points a through g on the phase diagram according to the number of phases present at each point.

One phase:             Two Phases:        Three Phases:

Find the eigenvalues λ_n and eigenfunctions y_n(x) for the given boundary-value problem. (Give your answers in terms of k, making sure that each value of k corresponds to two unique eigenvalues.)

y'' + λy = 0,  y(−π) = 0,  y(π) = 0

λ_{2k − 1} =, k=1,2,3,...

y_{2k − 1}(x) =, k=1,2,3,...

λ_2k =, k=1,2,3,...

A 38-mm thick HMA surface course is to be designed to carry 15,000,000 ESALs during the life of the pavement. A 9.5-mm nominal size aggregate is required. The aggregates shown in Table 4-14 are available for use. The control limits and restricted zone boundary are shown in Table 4-10. Based on environmental information, a PG 64-22 is used as the binder. Design a HMA mix according to the Superpave method.

(a) State any five issues dealt with in the regulatory framework of accounting.

(b) Outline any four benefits multinational companies may derive from global harmonization of accounting standards.

(c) In preparing financial statements, accountants follow certain fundamental assumptions and policies. List and explain two of these policies and assumptions under the following:
(i) boundary rules
(ii) measurement rules
(iii) ethical rules

Church organs have a set of pipes with different lengths. With those different pipes organs can produce sounds over a wide range of frequencies. If the lowest frequency produced by an organ is 31.6 Hz, and the highest frequency is 1.80 kHz, then what is the shortest possible wavelength of sound the organ can produce? Assume that the speed of sound is 336 m/s.
B) What is the longest possible sound wavelength the organ can produce?

1. What are point defects? Please explain the relationship between point defects and materials strength and ductility. (10 pts) 2. What are dislocations? Please explain the relationship between dislocation and materials strength and ductility (10 pts) 3. What are grain and grain boundary? Please explain the relationship between grain size/grain boundary and materials strength and ductility. (10 pts) 4. What is the solid solution and what factors affect solubility? (5 pts) 5. What is the stacking fault? (5 pts) 6. What is a unit dislocation? What is a partial dislocation? What is an extended dislocation? (10 pts) 7. The actual strength of a metallic material is tens of times smaller than its theoretical strength because of dislocation. However, the strength of the same material can be significantly increased through dislocation strengthening. Why does dislocation appear to behave in an opposite way? (10 pts) 8. Please use the characteristics of chemical bonding, crystal structures and dislocations to explain why metallic materials are strong and ductile and why ionic and covalent materials are strong but brittle? (20 pts)

A boundary survey is being conducted for a client’s parcel of land. You find and accept a concrete monument for a boundary corner and determine its position to have X and Y coordinates of 3496.45 ft & 9798.03 feet, respectively (Corner A). You also find & accept an iron rod as a corner and determine its position to have X and Y coordinates of 5272.92 ft & 10161.36 feet, respectively (Corner C). You determine that you should replace a lost corner (Corner B) between these accepted monuments using record distances provided on a 1995 survey map. The record distance from Corner A to B is 1405.91’. The record distance from Corner C to B is 1121.30’. What are the coordinates the field crew should use to reset corner B? HINT: You will get 2 solutions using distance-distance intersection techniques. Calculate both solutions but chose the solution that is northeasterly from Corner A & northwesterly from Corner C as your final solution. Also, use Civil 3D to check your answer. Show screenshot of your steps. Hint: by plotting the given coordinates and then using circles with radii, we can determine the intersection points.
