uestion 5 Krispy Kreme Donuts has a leverage of 2.5 What does this mean? (Hint- leverage is calculated as Assets/Equity and you purchase assets with either equity or debt) $2.50 of assets is funded with $1.00 of debt and $1.50 of equity. $2.50 of assets is funded with $1.00 of equity and $1.50 of debt. Assets are funded with 250% debt. Assets are funded with 25% equity. 2.5 donuts equal 1 donut hole Solution Leverage = Assets/ Equity 2.5/1 = 2.5 Assets are 2.5, Equity is 1 Hence the correct option is $2.50 of assets is funded with $1.00 of equity and $1.50 of debt. .

Type of financial crisis Type of financial crisis Solution There are mainly 5 types of financial crisis: 1. Banking Crisis - when there is a run on a bank/financial institution. e.g run on Washington Mutual in 2008 2. Currency Crisis - when there is a sudden and wide fluctuation in exchange rate. e.g the recent exchange variation in rouble 3. Speculative Bubbles and Crashes - when there is a sudden crash in the price of speculative assets, like the dot com bubble of 2000 4. International Financial Crisis - Multination crisis, usually caused by very high levels of current account defict. e.g the asian crisis during 1997-98 5. Wider Economic Crisis - A long duration of negative growth or recession. e.g the recession during 2008-09 .

Typing Answer is Mandatory! Explain the difference between cyclic hydrocarbons, aliphatic compounds, and aromatic compounds. Solution ALIPHATIC COMPOUNDS Compounds whose carbon atoms are linked in open chains, either straight or branched, rather than containing a benzene ring. Alkanes, alkenes, and alkynes are aliphatic compounds. For example methane, propane AROMATIC COMPOUND: Aromatic compounds, also known as arenes or aromatics, are chemical compounds that contain conjugated planar ring systems with delocalized pi electron clouds instead of discrete alternating single an double bonds. when they follow huckle rule they are called aromatic thisÂ Â rule states that if a cyclic, planar molecule has 4n+2 ? electrons, it is considered aromatic. For example benzene, toluene CYCLIC HYDROCARBONS cyclic compounds are formed when carbon atoms bond together to form ring like structures. All the carbon carbon bonds are single bonds unlike aromatic compounds. For example cyclohexane. .

type of accounts Solution Solution: 1. All of the three are types of Accounts Receivable Uncollectible methods i.e. 2. To arrive at an accurate balance in Bank reconciliation statement, deposits in transit should be subtracted in book . Example - Book balance after deposit of $ 5,000 - $ 10,000 Bank balance during deposit in transit - $ 5,000. In order to match the balance, $ 10,000 - $ 5,000 = $ 5,000 3.To arrive at an accurate balance in Bank reconciliation statement, the service charged should be subtracted or debited from the cash book. Example - Suppose service charged by the bank is $ 50, already subtracted, in order to meet tha balance, this should be subracted from cash book as well. 4. Double declining method and written down value method ignore salvage value of the asset. 5. Current assets can be defined as the assets which held to be sold within in a period od 12 months. Assets which are held for more than 12 months are non-current assets. Further, current assets are either cash or cash equivalents which can be converted into cash within one year or 12 months. .

Two KPMG auditors, Kevin Hall and Rosemary Meyer, were accused of improper professional conduct in the audit of the financial statements of USFoodservice, a distribution company. US Foodservice in?ated the revenue reported by the company by recognizing income from ?ctitious promotional allowances or recognizing the promotional allowance early. The two KPMGauditors identi?ed valuation, existence, and completeness of the promotional income and receivable as a signi?cant audit area. During the audit, they found numerous cases where the company recognized promotional income when they should not have. In vouching vendor payments received by the company, the auditor discovered that the company had recognized signi?cant unearned prepayments of promotional allowances as income. The working papers show that the auditors identi?ed the revenue recognition attached to these prepayments as audit adjustments, but the adjustments were subsequently removed by liquid white-out. The very existence of the prepayments in the vendor payment ?le contradicted management Solution 1)a)The auditor must state in the auditor\'s report whether the financial statements are presented in accordance with generally accepted accounting principle. b)The auditor must obtain a sufficient understanding of the entity and its environment, including its internal control, to assess the risk of material misstatement of the financial statements whether due to error or fraud, and to design the nature, timing, and extent of further audit procedures. c) The auditor determines that informative disclosures are not reasonably adequate, the auditor must so state in the auditor\'s report. In this case, all three points are ignored. 2)No, the auditor not meet the requirements because auditor have improfessional conduct on his report. 3)Auditor failed to do proper Standards of Field Work as well as Standards of Reporting. .

Question 19 of 20 5 0 Points A important part of weather science is \"hot air rises\". This is an example of A. conduction B. convection C. radiation es Previous Save F5 FO F F4 F3 F1 F2 Esc Solution \'Hot air rises\' is an example of Convection . It takes place due to bulk motion of molecules within a fluid. Gases and liquid can both be considered fluids. Convection occurs naturally on earth as fluid motion takes places due to differences in density occuring because of change in the temperature gradient. A rise in temperature reduces the density of a fluid and causes it to float over the regions of high density and creates a gap. This gap is filled with surrounding cooler air which rises up again due to heat. This sets up convection current and forms the basis for weather patterns, sea breezes etc Radiation is heat transfer by electromagnetic waves at the speed of light. A hot object radiates heat in the form of waves and it does not require any material medium for propogation. Example for radiation is the Sun\'s energy reaching earth through space which basically is Space (vacuum) having no medium while earth\'s atmosphere consists of air (a composition of gases). .

Question 8. [14 marks] (a) Explain how UV-vis absorption and fluorescence spectrophotometers differ using fully labelled block diagrams. (10 marks) What is the difference between emission and excitation spectra? Which resembles absorption spectra, and why? (4 marks) (b) Solution a) UV-visible refers to absorption spectroscopy in the UV and visible portion of the electromagnetic spectrum. When a molecule (typically starting out in a singlet ground state) absorbs a photon it will become an excited state molecule. Following quantum mechanical selection rules, the molecule will be in a singlet excited state. Fluorescence is one of many relaxation processes by which a molecule in the excited state can relax back down to the ground state. In fluorescence, a molecule in the lowest vibrational level of of a singlet excited state emits a photon to return to the ground singlet state. Most commonly molecules return to the ground state by a mechanism referred to as internal conversion and energy is conserved by heat being absorbed by the surroundings. Other relaxation mechanisms include phosphorescence, quenching by either an electron transfer or fluorescence energy transfer. An excited state molecule can also undergo photo-decomposition or photochemistry. The bottom line is that a molecule in the excited state is there for a limited amount of time. Fluorescence is but one mechanism to depopulate the excited state. b) The excitation spectrum shows at what wavelengths the solution uses to produce its fluorescence. The emission spectrum shows what wavelengths are given off from the solution. Since the excitation spectrum has the same peaks as the absorbency spectrum, so excitation spectra resembles absorption spectra. .
