Kirchoff stated 2 laws concerning currents in an electrical circuit.
[1] One of these states that the sum of the potential changes (voltages) around any closed loop equals zero. What property of the electric potential at a point is the basis for this law?

[2] The other law states that the sum of currents entering a node must equal the sum of the currents leaving the node (or the sum of currents, with signs, at a node equals zero). (a) Given perfect conductors, what is the net charge at a node?

(b)What conservation law, when combined with (a), forms the basis for this second Kirchoff law?

Essay 2

The Effect of International Financial Reporting Standards on Current Tax Planning Strategy

For this assignment, you will be submitting an essay on the effect the adoption of IFRS has had and will continue to have on tax planning strategy. While reporting under IFRS will not be required until 2015 or 2016, we are already beginning to see changes in the tax industry, particularly when considering planning for the future. The purpose of this assignment is for you to consider how and to what extent the adoption of IFRS in the United States will affect current tax planning strategy, both in the short-term and the long-term.

1. What is the space of analysis of the multiplier model? What is the significance of the 45 degree line in the Aggregate Production curve? Draw an aggregate production curve.

2. What are Aggregate Expenditures (AE)? Be sure to distinguish both autonomous and induced expenditures.

3. What is the slope of the Aggregate Expenditure function? What is its significance?

4. Show equilibrium in the Keynesian multiplier model. Identity the stability of equilibrium using the notion of unintended inventory changes.

5. Write the formula for the multiplier and identify the algebraic condition of the change in aggregate expenditure with respect to the change in real income.

There are two goods – c and p. The utility function is U (P,C) = P ^0.75 C ^0.25. $32 is allocated per week for the two goods, c and p.

1. The price of p is $ 4.00 each, while the price of c is $ 2.00 each. Solve for the optimal consumption bundle.
2. Suppose that the price for good p is now $ 2.00 each. Assuming nothing else changes, what is the new optimal consumption bundle.
3. Draw the appropriate diagram to show the results. Carefully explain the graphical representation of the fall in the price of p. Assume that both goods are normal goods.

Simulations with a general circulation model (GCM) have been used to

investigate the climate sensitivity to large changes in atmospheric ozone.

Explain qualitatively the results below.   

A simulation in which all O₃ above 30 km altitude is removed shows a large

tropospheric warming (+1-3^oC) and a very large stratospheric cooling (up to

-80^oC).

A simulation where all O₃ in the upper troposphere is removed shows a 1^oC

cooling of the Earth’s surface, while a simulation where the same amount of O₃ is

removed but in the lower troposphere shows no significant temperature change.

1, Which carries more energy, yellow light with a wavelength of 580 nm or green light with a wavelength of 560 nm? (Explain or show a calculation).

2,Why do we see a characteristic color (in the flame) for each cation?

4,The energy of an electron in n = 1 for a hydrogen atoms was found to be -2.179 x10-18 J/atom. Convert this value to kJ/mole.

5,Calculate the energy of light emitted when an electron changes from n = 3 to n = 1 in the hydrogen atom. In what region of the spectrum is this radiation found?

Situation. Suppose that a pizza vendor at a basketball game can sell 3,000 slices of pizza per night at a price of OMR 3 per slice. If the vendor raises the price to OMR 4 per slice, the number of slices sold falls to 2,000. Please answer the following questions:

Q1. Calculate the PRICE ELASTICITY OF DEMAND with clear steps of working and formulae.   [4marks]

Q2. The observed value belongs to which type of price elasticity of demand? [1mark]

Q3. Describe in your own idea the demand situation and the shape of its curve in relation to the market changes.

(briefly explain and answer questions 1-4)

1.During fasting, muscle protein breakdown and lipolysis in adipose tissue are accelerated. How do these changes enhance glucose production by gluconeogenesis in liver?

2.Why might a genetic mutation in glucose 6-phosphate dehydrogenase alter the rates of synthesis of lipids?

3.How many ATP molecules would you expect from the conversion of a-ketoglutarate to malate in tightly coupled mitochondria?

4.The rate of oxidation of pyruvate by tightly coupled mitochondria is decreased if palmitoyl carnitine is added. Discuss the mechanism for this change.
