(2b) The slope of a graph of tensile stress against tensile strain represents the Young's modulus of the material. This modulus is a measure of the stiffness of the material and is defined as the ratio of tensile stress to tensile strain in the linear portion of the stress-strain curve. (5) (i)They are used to make permanent magnets, which are essential in motors, generators, and various electronic devices. (ii)Ferromagnetic materials are also used in magnetic storage media, including hard drives and magnetic tape, due to their ability to maintain a magnetic state without an external field. (iii)They are utilized in transformers and inductors, which are critical components in power supplies and electrical circuits, where they enhance the magnetic coupling between coils. •••••••••••••••••••••••••••••••••••••••••••••••••••••••• (2a) (i)Monitoring and studying Earth's weather and climate by capturing continuous images and data of Earth's surface and atmosphere. (ii)Facilitating global communications, especially in high-latitude regions that are difficult to reach with geostationary satellites. (2b) The slope of a graph of tensile stress against tensile strain represents the Young's modulus of the material. This modulus is a measure of the stiffness of the material and is defined as the ratio of tensile stress to tensile strain in the linear portion of the stress-strain curve. (1a) ¥= force/length Recall, mass= kg= M, length=m = L; time=s= T So, Force= mass × acceleration = mass × velocity/time = mass × displacement/time × 1/time = mass × displacement/(time)² = kg × m/s² = kgm/s² Dimension= ML/T² Length= m Dimension= L Thus, ¥= (ML/T²) ÷ L = ML/T² × 1/L = ML/LT² = M/T² (1b) gravimeter.

(3a) Ose operate with Single Entry System of bookeeping. This system is typically used by small businesses or sole proprietors who do not keep proper books of account. In the single entry system, only one side of each transaction (either debit or credit) is recorded, which contrasts with the double entry system where every transaction affects at least two accounts. (3b) ADVANTAGES: (PICK ANY THREE) (i)The single entry system is easy to understand and use, making it accessible to those without formal accounting knowledge. It involves fewer records and less complex procedures. (ii)Implementing and maintaining a single entry system is inexpensive. It does not require advanced accounting software or professional accountants, which can be costly for small businesses. (iii)This system takes less time to manage compared to the double entry system. Business owners can spend more time focusing on their core operations rather than on detailed bookkeeping. (iv)The single entry system requires minimal paperwork and fewer records. This reduces the administrative burden on the business owner. (v)The system offers flexibility as it does not follow strict accounting rules and procedures. This can be advantageous for small businesses with straightforward transactions. DISADVANTAGES: (PICK ANY THREE) (i)The single entry system can lead to incomplete and inaccurate financial records. Since it does not track both sides of transactions, there is a higher risk of errors and omissions (ii)Due to the lack of checks and balances inherent in the double entry system, the single entry system is more susceptible to fraud and errors. It is difficult to detect discrepancies and irregularities. (iii)The limited financial information provided by the single entry system makes it difficult for business owners to make informed decisions. Critical financial metrics and insights are often missing. (iv)Financial institutions typically require detailed and accurate financial records when assessing loan applications. The single entry system’s lack of comprehensive financial data can make it difficult for businesses to obtain financing or attract

FINANCIAL ACCOUNTING ESSAY ANSWERS (1a) (i) Purchase of office equipment on credit: This transaction would be recorded in the purchases journal or the purchases day book. (ii) Credit purchases: Also recorded in the purchases journal or the purchases day book. (iii) Bank charges: These would typically be recorded in the cash book under the bank column. (iv) Goods returned by a customer: Recorded in the returns inward journal or the returns inward book. (1b) (i) Purchases: From the purchases journal or purchases day book. (ii) Cash payments: From the cash book. (iii) Returns outwards: From the returns outwards journal or returns outwards book. (iv) Discount received: From the cash book or the discount received journal. (v) Petty cash payments: From the petty cash book or petty cash vouchers. (1c) (i) Sales ledger: This ledger records all credit sales transactions. It contains individual accounts for each customer, detailing their purchases on credit and any payments made against those purchases. (ii) Purchases ledger: This ledger records all credit purchases transactions. It contains individual accounts for each supplier, detailing the goods purchased on credit and any payments made to them. (iii) General ledger: Also known as the nominal ledger, it records all financial transactions of a business. It contains various accounts such as assets, liabilities, equity, revenues, and expenses. Transactions from subsidiary ledgers like sales ledger and purchases ledger are summarized and posted to the respective accounts in the general ledger.
