An alternating current (AC) circuit consists of a resistor of resistance $R = 30\ \Omega$ , an inductor of inductive reactance $X_L = 80\ \Omega$ , and a capacitor of capacitive reactance $X_C = 40\ \Omega$ connected in series across an AC source of RMS voltage $150\ \text{V}$ . What is the average power dissipated in the circuit in watts?

Cevabı ve açıklamayı göster

Cevap: 270

Cevap

The average power dissipated in the circuit is

270\ \text{W}

The total impedance of a series RLC circuit is

Z = \sqrt{R^2 + (X_L - X_C)^2} = \sqrt{30^2 + (80 - 40)^2} = 50\ \Omega

. The RMS current is

I_{\text{rms}} = \frac{V_{\text{rms}}}{Z} = \frac{150}{50} = 3\ \text{A}

. Because pure inductors and capacitors consume zero average power over a complete cycle, power is dissipated only across the resistor, giving

P = I_{\text{rms}}^2 R = 3^2 \times 30 = 270\ \text{W}

Adım Adım Çözüm

Calculate net reactance

X = 40\ \Omega

Inductive and capacitive reactances oppose each other in phase, so net reactance is

X_L - X_C

Calculate total circuit impedance

Z = 50\ \Omega

Resistance and net reactance add in quadrature:

Z = \sqrt{R^2 + (X_L - X_C)^2}

Calculate RMS current

I_{\text{rms}} = 3\ \text{A}

Ohm's law for AC circuits gives

I_{\text{rms}} = \frac{V_{\text{rms}}}{Z}

Calculate average power dissipated

P = 270\ \text{W}

Power is dissipated exclusively by resistance in an AC circuit:

P = I_{\text{rms}}^2 R

To stimulate growth in key developmental sectors such as agriculture and manufacturing without restricting the overall credit supply across the entire economy, the central bank directs commercial banks to allocate specific percentages of their loan portfolios to these designated sectors. Which type of monetary policy instrument is being deployed in this scenario?

Selective credit control

Open market operations

Cash reserve ratio adjustment

Bank rate policy

Cevabı ve açıklamayı göster

Cevap: Selective credit control

Cevap

Selective credit control

Selective credit control (also known as qualitative monetary control) refers to central bank measures intended to regulate the flow of credit into specific sectors or uses in the economy. Directing commercial banks to allocate explicit loan quotas to priority sectors like agriculture and manufacturing fits this definition.

Adım Adım Çözüm

Analyze the central bank's objective and implementation strategy in the given scenario.

The central bank is targeting specific sectors (agriculture and manufacturing) using credit allocation quotas rather than altering the total volume of money circulating in the economy.

Distinguishing between policies that alter aggregate credit volume versus policies that steer credit to particular uses determines the category of monetary instrument.

Classify the instrument as quantitative (general) or qualitative (selective).

Instruments that influence the destination or allocation of credit rather than its overall quantity are classified as selective or qualitative credit controls.

Quantitative tools (such as Open Market Operations, reserve requirements, and bank rates) affect the overall liquidity indiscriminate of sector, while qualitative/selective tools focus on sector-specific credit distribution.

+7.0\text{ D}

-3.0\text{ D}

+0.03\text{ D}

Cevabı ve açıklamayı göster

Cevap: $+3.0\text{ D}$

Cevap

The combined optical power of the lens system is

+3.0\text{ D}

The individual power of the converging lens is

+5.0\text{ D}

and the power of the diverging lens is

-2.0\text{ D}

. Summing these values algebraically yields a net power of

+3.0\text{ D}

Adım Adım Çözüm

Convert the focal length of each lens from centimeters to meters and apply sign conventions.

Converging lens focal length

f_1 = +0.20\text{ m}

; Diverging lens focal length

f_2 = -0.50\text{ m}

Optical power in dioptres requires focal length to be expressed in meters, with converging lenses being positive and diverging lenses being negative.

Calculate the individual power of each lens.

P_1 = \frac{1}{+0.20} = +5.0\text{ D}

and

P_2 = \frac{1}{-0.50} = -2.0\text{ D}

Power of a thin lens is defined as

P = \frac{1}{f}

where

f

is in meters.

Sum the individual powers to find the total power of thin lenses in contact.

P = P_1 + P_2 = +5.0\text{ D} + (-2.0\text{ D}) = +3.0\text{ D}

When thin lenses are in contact, their net optical power is equal to the algebraic sum of their individual powers.

The table below shows selected economic metrics for two developing nations, Country X and Country Y, in the same fiscal year:

Indicator	Country X	Country Y
Per Capita Income ($)	4,200	2,100
Adult Literacy Rate (%)	48%	82%
Life Expectancy at Birth (Years)	54	71
Agriculture Share of GDP (%)	58%	18%

Based on the data provided, which of the following statements correctly evaluates the economic development status of both countries?

Country Y demonstrates a higher level of economic development than Country X because non-income indicators reflect better living standards, higher human capital, and structural transformation.

Country X is more economically developed than Country Y because per capita income is the sole definitive measure of national welfare.

Country X is more economically developed because nominal per capita income automatically adjusts for inflation and price level differences.

Both countries have attained an identical level of economic development because high per capita income offsets lower health and literacy scores.

Cevap: Country Y demonstrates a higher level of economic development than Country X because non-income indicators reflect better living standards, higher human capital, and structural transformation.

Cevap

Country Y demonstrates a higher level of economic development than Country X because non-income indicators reflect better living standards, higher human capital, and structural transformation.

Economic development refers to sustainable improvements in economic welfare, living standards, literacy, health, and structural transformation of the economy. While Country X has a higher per capita income, Country Y significantly outperforms Country X in adult literacy (82% vs 48%), life expectancy (71 vs 54 years), and structural diversification away from agricultural dependence (18% vs 58% of GDP). Therefore, Country Y reflects a higher level of overall economic development.

Adım Adım Çözüm

Distinguish between economic growth (quantitative income metrics) and economic development (qualitative welfare and structural metrics).

Country X has higher per capita income (

4,200 vs

2,100), indicating higher growth/output per head, but Country Y performs significantly better across developmental indicators.

Economic development is a multidimensional process encompassing health, education, and structural change, not just income level.

Analyze human capital and health metrics.

Country Y has a higher adult literacy rate (82% vs 48%) and higher life expectancy (71 years vs 54 years).

Higher literacy and life expectancy indicate superior human development and improved quality of life.

Analyze the structural transformation of the economy.

Country Y has a much lower share of agriculture in GDP (18% vs 58%), signaling diversification into industrial and service sectors.

Economic development is characterized by a structural shift of production away from primary agriculture toward secondary and tertiary sectors.

Divisibility

Cevabı ve açıklamayı göster

Cevap: General acceptability

Cevap

General acceptability is the primary characteristic that makes banknotes universally receivable for goods and services.

General acceptability is the most essential quality of money. Banknotes issued by the central bank are designated as legal tender, meaning members of the public are legally required and socially willing to accept them in discharge of debts. Private promissory notes lack this universal public trust and statutory mandate.

Unlike capital, which is a man-made agent of production with an elastic supply, land is fixed in total supply to the overall economy, meaning its economic reward is entirely demand-determined.

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: True

Cevap

The statement is true because the total supply of land is fixed (perfectly inelastic) to the economy as a whole, making its economic reward (rent) entirely dependent on demand.

Land is a primary factor of production provided by nature without human cost. Because its overall quantity cannot be expanded, its supply is perfectly inelastic, causing its economic reward (rent) to be governed entirely by demand.

Adım Adım Çözüm

Analyze the fundamental characteristics of capital versus land.

Capital consists of man-made physical or financial assets whose supply can be increased or decreased over time, whereas land is a natural factor whose overall supply is physically fixed.

Identifying the supply characteristics of factors of production determines how their economic returns are structured.

Examine the price-determination mechanism for a factor with fixed supply.

Because total land supply cannot adjust in response to price changes, the economic rent accrued to land owners is dictated solely by the level of demand from producers.

When factor supply is completely inelastic, supply curves are vertical, making market price a direct function of demand.

Cevap

Nkechi has a right of particular lien over the machinery, enabling her to retain possession until her lawful expenses and commission are paid by Bature Enterprises.

Under the Law of Agency, an agent who has lawfully incurred necessary expenses (such as freight and storage) and earned remuneration in handling the principal's goods is entitled to a right of particular lien. This right allows the agent to lawfully retain possession of the goods against the principal until all lawful claims for reimbursement and commission regarding those specific goods are satisfied.

Adım Adım Çözüm

Identify the agent's rights when out-of-pocket expenses and commission are owed by the principal.

Under commercial agency law, an agent has a right to be indemnified for expenses reasonably incurred and to receive agreed remuneration.

Agents act on behalf of principals and should not suffer personal financial loss for authorized actions.

Determine the legal mechanism available to secure unpaid claims when the agent has possession of the principal's goods.

The agent possesses a possessory right of lien over the principal's goods currently in the agent's lawful custody.

A particular lien allows the agent to hold the specific goods in respect of which the debt (expenses and commission) was incurred until payment is made.

Evaluate the effect of the principal's abrupt revocation of agency.

While a principal can generally revoke an agent's authority, such revocation does not destroy existing accrued rights or possessory liens held by the agent.

Pre-existing possessory security rights remain intact despite revocation of future authority to act.

Small-scale production enterprises typically feature an extensive division of labour and a high degree of specialization among their workforce.

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: False

Cevap

The statement is false. Small-scale production enterprises operate with limited output volumes and small workforces, which restricts the scope for implementing an extensive division of labour. Specialized task division is a fundamental characteristic of large-scale production.

Extensive division of labour requires mass output, heavy machinery, and a large workforce to sustain specialized roles. Small-scale production enterprises operate under limited capital and small staff numbers, forcing workers to execute multiple general tasks rather than highly specialized processes.

Adım Adım Çözüm

Examine the prerequisites for extensive division of labour in production.

Subdividing work into minute, repetitive tasks requires high output volume, market demand, and a large workforce to keep specialized workers continuously occupied.

Without sufficient scale, specialized workers remain idle, causing operational inefficiency.

Analyze the operational constraints of small-scale production.

Small-scale firms possess limited capital, small machinery, and a small employee count.

These resource limits make breaking down tasks into highly specialized individual roles economically impractical.

Differentiate worker roles between small-scale and large-scale enterprises.

Workers in small-scale units undertake general, multi-functional duties, whereas large-scale units employ specialized workers along assembly lines.

Extensive specialization and division of labour are hallmarks of large-scale, mass-production systems.

Cevap

Moral Suasion matches informal persuasion or guidance; Lender of Last Resort matches provision of emergency financial accommodation; Special Deposits matches mandatory compulsory funds beyond statutory reserve ratios; Bank Rate matches the minimum official discount rate charged to commercial banks.

Each instrument accurately aligns with its operational definition: Moral Suasion represents informal advice to commercial banks; Lender of Last Resort provides emergency liquidity assistance to banks in distress; Special Deposits freeze extra cash reserves beyond standard statutory ratios; and the Bank Rate is the official rate for central bank lending.

Adım Adım Çözüm

Differentiate qualitative tools, quantitative tools, and traditional functions of the Central Bank.

Moral Suasion is qualitative/persuasive; Lender of Last Resort is a core traditional function; Special Deposits and Bank Rate are quantitative instruments.

Classifying each item helps connect its economic mechanism to its specific operational definition.

Pair each concept in Column I with its matching description in Column II.

Moral Suasion connects to informal persuasion; Lender of Last Resort connects to emergency assistance; Special Deposits connects to immobilising extra liquidity; Bank Rate connects to the central bank's discount lending rate.

Matches every Central Bank instrument and function precisely to its established role in monetary regulation.

During a anatomical examination of the circulatory system in adult ectothermic vertebrates, a biologist observes a heart containing two auricles (atria) and a single ventricle that is partially divided by an incomplete septum. Which class of vertebrates possesses this cardiac architecture?

Reptilia

Amphibia

Pisces

Aves

Cevap: Reptilia

Cevap

Reptilia

Members of the class Reptilia (such as lizards, snakes, and turtles) feature a three-chambered heart composed of two auricles and a single ventricle partially divided internally by an incomplete septum, which minimizes the mixing of oxygenated and deoxygenated blood streams.

Adım Adım Çözüm

Identify the key anatomical features described in the stem.

The heart has two auricles and one ventricle with an incomplete partition (septum).

This structural pattern determines the evolutionary stage of the vertebrate circulatory system.

Compare heart chamber configurations across poikilothermic vertebrate classes.

Pisces have 2 chambers (1 auricle, 1 ventricle); Amphibia have 3 chambers (2 auricles, 1 undivided ventricle); Reptilia have 3 chambers (2 auricles, 1 partially divided ventricle).

The partial ventricular septum is a key evolutionary adaptation in non-crocodilian reptiles that reduces mixing of oxygenated and deoxygenated blood.

Cevap

Bank Rate Policy matches the official minimum rediscount rate for commercial bills; Cash Reserve Ratio matches the statutory percentage of deposits kept with the central bank; Moral Suasion matches informal non-statutory persuasion and guidance; Open Market Operations match the buying and selling of government securities.

Each instrument correctly corresponds to its primary function: Bank Rate Policy sets the rediscount rate for commercial bills, Cash Reserve Ratio dictates the required cash percentage held at the central bank, Moral Suasion acts through informal guidance, and Open Market Operations alter liquidity via buying/selling treasury securities.

Adım Adım Çözüm

Differentiate between quantitative and selective monetary tools.

Bank Rate, CRR, and OMO represent quantitative instruments controlling total liquidity, while Moral Suasion is a selective (qualitative) tool guiding credit distribution.

Categorizing instruments ensures clarity between general volume controls and persuasive directives.

Pair each instrument with its specific operational mechanism.

Bank Rate controls borrowing cost/rediscounts; CRR sets mandatory cash holding percentages; Moral Suasion relies on informal advice; OMO operates via market purchase and sale of securities.

Aligning instruments to their operational definitions confirms full conceptual understanding of Central Bank monetary policy instruments.
