Required: Does FedEx sponsor defined benefit pension plans for its employees? Defined contribution plans? Postretirementhealthcare plans? What amount does FedEx report in its balance sheet in 2017 for its U.S. pension plans? For its postretirementhealthcare plans? FedEx reports three actuarial assumptions used in its calculations of the projected benefit obligation. Whatwere those three amounts in 2017? Did reported changes in those assumptions from the previous yearincrease, decrease, or have no effect on the projected benefit obligation

1. A _________________ _________ causes light rays from a distant source to converge to a _____________ ______________

2. Charging by induction, a charged rod is brought near a neutral conductor: the electrons in the conductor redistribute such that there is a net positive charge away from the rod (T/F)

3. Electrical resistivity doesn’t change when temperature changes (T/F)

4. With a magnetic core, the total magnetic field is increased by a factor of 10^3 to 10^4 relative to the field without a core. It is described by saying that the magnetic materials have a large _______________ _________________

Q. Assume that you are deciding whether to move to Umeå or stay in Stockholm. If you stay you will earn a constant wage wS throughout your career, and if you move you will earn wU throughout your career. Also assume that you live and work forever. Moving costs are equal to M.

a) Derive the condition under which you are indifferent between moving and staying.

b) Explain how changes in moving costs, in the interest rate and in the wage differential (wU–wS) would affect your decision

Consider the pizza restaurants and explain the following issues.

1. Explain the effect of a horizontal integration of all the firms in the industry on the pricing behavior of the merger.

2. Given the merger in point 1, explain the changes in the concentration of the industry.

3. Given the merger in point 1, explain the relationship between the elasticity of the industry demand and that of the firm.

4.Given the merger in point 1, explain how entry into the industry is affected.

5. Explain the value of the Lerner index for the competitive market. Explain why the competitive market has a very low concentration.

1. A mixing chamber takes in a stream of R134-a at 1 MPa and 12◦C and a second stream at 1MPa and 60 ◦C. The first stream has twice the mass flow of the second; m₁ = 2m₂ No data is given about the stream 3 exiting the mixing chamber. Therefor, you will need to make two approximations typical for mixing chambers. One is that the pressure changes across the chamber are negligible. You are asked to find the exit temperature and the exit quality if it is defined. Construct all phases that are not given in a Pv diagram. Label the lines with their values.

a. When funded by borrowing, what effect will expansionary fiscal policy have on the loanable funds market?

• An increase in the supply of loanable funds

• An increase in the demand for loanable funds

• A decrease in the supply of loanable funds

• A decrease in demand for loanable funds

b.

If a fiscal policy action causes "crowding out," what would most likely be the result?

Decreased gross investment

• Decreased net exports

• Increased net exports

• Increased consumer expenditures

c.True or false: Changes to government purchases, but not taxation, cause "crowding out" to occur.

Kristie is a 60 kg skier. At the start of a ski-slope that is at 30o to the horizontal, she crouches into a tuck. The surface is very icy, so that there is no friction between her skies and the ice. a) If Kristie starts from rest, what is her speed after travelling a distance 80 m on the ice? b) Snow condition changes at the end of ice path so that Kristie continues down the slope with a constant velocity. Determine the co-efficient of kinetic friction between her skies and the path with changed snow condition.

Mr Jims, 68 year-old man presented to the Emergency Department following a house fire. The flat below his had caught fire during the night, and the smoke rose through the floors and windows, and the patient was exposed to significant smoke inhalation. He is suspected to have carbon monoxide poisoning. Answer the following questions based on the scenario. 6.1) What might be the pathophysiological changes brought about by carbon monoxide in his body? 6.2) Enlist the seven (7) possible signs and symptoms that the patient may manifest?

Which of the following statements about topoisomerases is FALSE?

Type I AND type II topoisomerases can both increase or decrease L.

In the reaction catalyzed by type I topoisomerases, the enzyme changes conformation to provide the energy required to change the linking number of the DNA.

Type I topoisomerases use a tyrosine side chain in their active site to catalyze a nucleophilic attack.

Type I topoisomerases do not use ATP in their reaction mechanism.

Type II topoisomerases can increase writhe because they use ATP in their reaction mechanism.

Consider a small open economy where workers care about their real consumption wage. Assume, in addition, that the Marshall-Lerner condition holds. This economy starts at the longrun equilibrium and suddenly experiences the following shock. Households get easier access to mortgages and, as a result, the savings rate falls in this economy. What will be the effect of this shock on the medium run equilibrium in this economy? Describe the changes in the equilibrium employment, RER, Trade Balance and real consumption wage. Draw the appropriate diagrams and briefly explain your reasoning. [Word limit = 250 words]
