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. .

Question 6 (1 point) Which of the following statements about hydrophobic interactions is FALSE? They are caused by hydrophobic molecules interacting strongly with each other. They are the driving force for micelle formation. When nonpolar molecules come in contact with water, a highly-ordered shell of water molecules forms at the interface between the nonpolar molecules and water. A hydrophobic interaction is caused by the desire of water molecules to regain the entropy lost during this organization around the nonpolar substance by excluding the substance from interaction with water molecules They are entropy driven. They are the main driving force for protein folding into three dimensional structures Solution Ans: They are caused by hydrophobic molecules interacting strongly with each other. Hydrophobic (water fearing, literally) interactions are between water molecules and hydrophobes, generally nonpolar organic molecules. Due to these interactions water and the hydrophobes segregate to minimize area of contact between the two phases. .

Question 4 (1 point) E Which of the following is the reason that C-H cannot serve as a donor for a hydrogen bond? 1) Lacks a temporary ditple o 2) Lacks a permanent dipole 3) Lacks a permanent charge 4) Aggregates in water Save Solution Ans. Correct option- 2. Lacks a permanent dipole. Hydrogen bond is a weak attractive force between a highly electronegative atoms (O, N, F) and a H-atoms linked to such atoms. The criteria for H-bonds formation is that there must be - I. A highly electronegative atom ( F, N, O -atom), and II. A H-atoms linked to such atoms (F, N, O). The highly electronegative atom with an H-atom linked to it served as the H-bond donor. Due to greater difference between the electronegativity of (F, N, O) and H-atoms, these bonds (F-H ; N-H ; and O-H) have permanent dipole. So, to act as an H-bond donor, the bond must have a significantly higher permanent dipole moment . # Due to low difference between the electronegativity of C and H-atoms (around 0.35 units), the C-H bond is considered non-polar, i.e. does not have a permanent dipole moment. Because the C-H bond does not have a permanent dipole, it canâ€™t act as a H-bond donor. # Option 1, 3- Incorrect . Temporary dipole and presence of charge is NOT an absolute necessity for the bond to act as H-bond donor. # Option- 4. Incorrect. The C-H bond itself does not represent any molecule. So, itâ€™s aggregation in water canâ€™t be correlated with its ability to act as H-bond donor. .
