It requires substantial energy to reduce metal ore to pure metal. The reverse process, corrosion, happens spontaneously. The rusting of iron, the tarnishing of silver, and the formation of patina on copper and brass are some common examples of corrosion.

Rusting is the greatest corrosion problem because it occurs rapidly and because so many objects are made of iron and steel. A great deal of the annual production of iron goes simply to replace that lost by rusting. Iron will not rust in dry air or in water that is completely free of air. Oxygen gas and water must be present for iron to rust. Describe chemistry and electrochemistry of corrosion of iron and copper. In each redox reaction, specify the element that is being oxidized, the element that is being reduced, and identify the oxidizing and the reducing agent. Why cars rust more rapidly near the beach or in cold climate where salt is used to de-ice the roads?

2. Explain the factors that would affect the supply and demand for your major product/service.
3. List some economic resources you would need to produce your product/service. What scarcity, or opportunity costs do you need to consider?
4. Describe the economic indicators would you be most interested in knowing more about before starting this business and the current levels of these economic indicators. How will they affect your planning?

Assess your product/service against existing competitors (or providers of near-substitutes). What comparative advantage do you have?

While death maybe an unfortunate and inevitable occurrence in human life, the death of government policies was originally thought of as so or near impossible. Many researchers considered that termination can cause difficulties when trying to identify causal and predictable relationships. Possibly even more troublesome is the misunderstanding of what constitutes termination (Kinney, N, 2013).

However, the government of Malaysia have terminated several policies such as Teaching Science and Mathematics in English (PPSMI), Goods and Services Taxes (GST) and bend bridge project.

1. Based on the examples given above, do you agree with the author? Justify your answer

2. If you were hired as a public official and you were given instructions to terminate a program or a policy,

   1. i) how would you proceed?

   2. ii) would you apply the ‘big bang’ or the long whimper approach? Justify your answer?

Black hole formation as seen by a distant observer

Given that matter can never cross the event horizon of a black hole (from an external observer point of view), if a black hole is "fed" with a large amount of matter then the new matter will eventually become extremely compressed, and presumably would be compressed below its Schwarzchild radius.

Would secondary black holes eventually form near the original black hole?

As an alternative one could also imagine that the combined mass of the original black hole and the new mass around the event horizon becomes contained within the Schwarzchild radius of both masses, and so a new event horizon forms, "swallowing" the new mass around the edge of the original black hole.

This mechanism would allow black holes to swallow mass in a finite time.
Would this contradict GR predictions?

Be sure to 1) give the null and alternative hypotheses, 2) label which hypothesis is the claim, 3) Identify whether the test is left-tailed, right-tailed, or two-tailed, 4) name the test being used, 5) find the P-value for the sample, 6) state whether you reject or fail to reject the null hypothesis, and 7) give the conclusion in the context of the problem.

Sharkey’s Fun Center contains a number of electronic games as well as a miniature golf course and various rides located outside the building. Paul Sharkey, the owner, would like to construct a water slide on one portion of his property. Mr. Sharkey gathered the following information about the slide:

1. Water slide equipment could be purchased and installed at a cost of $405,000. According to the manufacturer, the slide would be usable for 12 years after which it would have no salvage value.
2. Mr. Sharkey would use straight-line depreciation on the slide equipment.
3. To make room for the water slide, several rides would be dismantled and sold. These rides are fully depreciated, but they could be sold for $72,500 to an amusement park in a nearby city.
4. Mr. Sharkey concluded that about 50,000 more people would use the water slide each year than have been using the rides. The admission price would be $4.20 per person (the same price the Fun Center has been charging for the old rides).
5. Based on experience at other water slides, Mr. Sharkey estimates that annual incremental operating expenses for the slide would be: salaries, $87,000; insurance, $5,000; utilities, $13,800; and maintenance, $10,600.

Required:

1. Prepare an income statement showing the expected net operating income each year from the water slide.

2-a. Compute the simple rate of return expected from the water slide.

2-b. Based on the above computation, would the water slide be constructed if Mr. Sharkey requires a simple rate of return of at least 14% on all investments?

3-a. Compute the payback period for the water slide.

3-b. If Mr. Sharkey accepts any project with a payback period of five years or less, would the water slide be constructed?

ACCOUNTING INTERMEDIATE 2

On 1st January 2014 Alex company dealers of electronic products purchased a building for $8,000,000. Its estimated useful life at that date was 20 years and the company applies straight line depreciation method. On 31st December 2018, the government launched a plan to construct a flyover adjacent to the building and the related construction reduced the access to the building due to the inability to park and enter to the building. Due to this reason the value for the building decreased. The company estimated that they can sell the building for $4,700,000 but it has to incur a cost of $205,000. Alternatively, if it continues to use it the present value of the net cash flows that the building would generate is $5,200,000. In 2019 the government constructed a service road parallel to the highway which improved the recoverable amount to $6,000,000. The depreciation for the year 2019 is $440,000 Calculate the carrying amount, recoverable amount and the necessary journal entries for the above scenario. You are required to:

A.Calculate accumulated depreciation & carrying value as at 31st Dec 2018, applying IAS 36.

B. Calculated recoverable amount & Impairment loss as at 31st Dec 2018 applying IAS 36.

C. Record relevant journal entries as at 31st Dec 2018 applying IAS 36 and amount to be recognized in statement of financial position.

D. Calculated carrying amount and amount of appreciation in building as at 31st Dec 2019 applying IAS 36.

E. Record relevant journal entry for regain in the value of impaired asset as at 31st Dec 2019 applying IAS 36.

F. A customer has made a claim against Alex Company for injury suffered following the purchases and use of a defective electronic product. Legal advisers have confirmed that Alex Company will probably have to pay financial compensation of $50,000 to the customers. In turn, Alex Company has made a counter claim against the suppliers of the defective products for $50,000 and believes it is probable that its claim against the supplier will be successful. Justify with reasons what adjustments, if any, should be made by Alex Company in the financial statements.
