Physics QUESTION #7071

Question 2

Two Carnot engines, A and B, operate in series. Engine A receives heat at $T_1 = 600 \text{ K}$ and rejects it to a reservoir at $T_2$. Engine B receives this rejected heat and rejects it to a sink at $T_3 = 400 \text{ K}$. If both engines produce the same amount of work, find $T_2$.

$600 \text{ K}$
$400 \text{ K}$
$300 \text{ K}$
$500 \text{ K}$✔️

Correct Answer Logic:

For two Carnot engines in series where the work output is equal ($W_A = W_B$):

$Q_1 - Q_2 = Q_2 - Q_3$

Since $Q \propto T$ for a Carnot cycle, we can write:
$T_1 - T_2 = T_2 - T_3$

Rearranging for $T_2$:
$2T_2 = T_1 + T_3 \implies T_2 = \frac{600 + 400}{2} = 500 \text{ K}$.

Question 3

A Judge of a High Court is qualified for appointment under Article 193 if they have been an advocate of a High Court for not less than:

Five years
Ten years✔️
Fifteen years
Twenty years

Correct Answer Logic:

Article 193(2)(a), as amended by the 26th Amendment 2024, provides that a person must have 'for a period of not less than ten years, been an advocate of a High Court.' The same period applies to judicial office under clause (2)(b). The earlier standard set by pre-2024 provisions required different periods.

Question 4

After 3 half-lives, the remaining fraction of a radioactive sample is:

$\dfrac{1}{2}$
$\dfrac{1}{4}$
$\dfrac{1}{8}$✔️
$\dfrac{1}{16}$

Correct Answer Logic:

After each half-life, the remaining fraction is halved. After $n$ half-lives: remaining fraction $= \left(\dfrac{1}{2}\right)^n$. After 3 half-lives: $\left(\dfrac{1}{2}\right)^3 = \dfrac{1}{8}$.

Question 5

Under Rule 25, the maximum permissible bid security that a procuring agency may require from bidders is:

Two percent of the estimated procurement value
Three percent of the estimated procurement value

Ten percent of the estimated procurement value

Correct Answer Logic:

Rule 25 (as inserted via S.R.O. 834(I)/2021) stipulates that a procuring agency may require bidders to furnish a fixed amount of bid security not exceeding five percent of the estimated value of the procurement as determined by the procuring agency.

English Literature QUESTION #10725

Question 6

The literary technique employed by James Joyce in his novels is known as:

Oblique narrative
Stream of Consciousness✔️
First person narrative
Naturalism

Correct Answer Logic:

Stream of Consciousness is the defining narrative technique of James Joyce. In works like Ulysses (1922) and A Portrait of the Artist as a Young Man (1916), Joyce represents the continuous flow of thoughts, feelings, memories, and associations passing through a character's mind, often without conventional punctuation or logical ordering. The technique was developed alongside Virginia Woolf and Dorothy Richardson.

Civil / Architecture QUESTION #2350

Question 7

In an airport Air Traffic Control (ATC) tower, the navigational and control systems have a typical operational lifespan requiring periodic electronic refits of approximately:

2–3 years
8–10 years✔️
15–20 years
25–30 years

Correct Answer Logic:

The Architects' Handbook states that navigational and control systems in ATC towers have a relatively short life of 8–10 years, resulting in three or four complete electronic refits during the tower's lifetime. Designing for upgradeability requires a clear distinction between the primary structural elements and secondary fittings such as partitions, cable systems, and raised floors.

Question 10

If $\varphi: \mathbb{Z}_{12} \to \mathbb{Z}_{18}$ is a group homomorphism, how many exist?

$6$
$4$
$12$
$\gcd(12, 18) = 6$✔️

Correct Answer Logic:

Number of homomorphisms from $\mathbb{Z}_m$ to $\mathbb{Z}_n$ equals $\gcd(m, n) = \gcd(12, 18) = 6$.

Accounting Finance and Punjab Sales Tax on Services QUESTION #2580

Question 11

Under section 16A(4), if the transferred payment amount is NOT deposited in the business bank account of the service provider, which party loses the right to claim input tax credit, adjustment, deduction, refund, repayment or zero-rating?

The service recipient
The service provider✔️
Both the service recipient and service provider
Neither party — the tax can be recovered from the bank

Correct Answer Logic:

Section 16A(4) provides that the amount transferred must be deposited in the BUSINESS BANK ACCOUNT of the service provider; otherwise THE SERVICE PROVIDER shall not be entitled to claim input tax credit, adjustment, deduction, refund, repayment or zero-rating. This is distinct from sub-section (3) which restricts the service recipient's rights.

Question 12

A regular hexagon is divided into 6 equilateral triangles. If the hexagon has an area of \(54\sqrt{3}\ \text{cm}^2\, what is the side length of the hexagon?

6 cm✔️
3 cm
9 cm
4 cm

Correct Answer Logic:

Area of regular hexagon with side \(s\: \(A = \dfrac{3\sqrt{3}}{2}s^2\

Setting equal: \(\dfrac{3\sqrt{3}}{2}s^2 = 54\sqrt{3}\

\(s^2 = \dfrac{54\sqrt{3} \times 2}{3\sqrt{3}} = \dfrac{108}{3} = 36\

\(s = 6\ \text{cm}\

Verification: \(\dfrac{3\sqrt{3}}{2} \times 36 = 54\sqrt{3}\ ✓

Question 16

The chief atmospheric layer present closest to Earth's surface is the:

Mesosphere
Ionosphere
Troposphere✔️
Stratosphere

Correct Answer Logic:

The troposphere is the lowest and densest atmospheric layer, extending from the Earth's surface to approximately 12 km altitude (varies from ~8 km at poles to ~16 km at equator). It contains ~75% of total atmospheric mass and ~99% of water vapour. All weather phenomena occur here. Temperature decreases with altitude (~6.5°C/km). Above the troposphere lie the stratosphere (ozone layer), mesosphere, thermosphere (ionosphere), and exosphere.

Electronics Engineering QUESTION #11699

Question 17

An inductor is tested with an LCR meter at 1 kHz. The measured inductance is correct but Q-factor reads 0.8 instead of the expected 50. The most likely fault is:

Shorted turns in the winding✔️
An open-circuit winding
Core saturation from DC bias
Wrong test frequency selected

Correct Answer Logic:

A drastically low Q-factor while inductance appears near-nominal is characteristic of shorted turns. Shorted turns create a transformer-like secondary loop that dissipates energy, dramatically increasing equivalent series resistance (ESR) and reducing Q. An open winding would give an OL reading; core saturation affects inductance under DC bias.

Archimedes' principle states that the buoyant force on a submerged (or floating) body equals:

Weight of the body
Weight of fluid displaced by the body✔️
Pressure at the centroid times surface area
Volume of the body times its own density

Correct Answer Logic:

Archimedes' principle: buoyant force $F_B=\gamma_{fluid}\times V_{displaced}$ — equals the weight of fluid displaced.

Administration QUESTION #9574

Question 20

The 'Government of India Act 1935' introduced two significant provisions relevant to Pakistan's current administrative structure. What were these provisions, and how did they shape the post-independence civil service?

It introduced the provincial civil service and created the post of Governor General — both were retained after independence with minor modifications
It provided security of tenure for civil servants (no dismissal without hearing/right of appeal) and gave the provinces financial autonomy — establishing the principle of civil servant protection that was later codified in Pakistan's Civil Servants Act 1973✔️
It created the Federal Public Service Commission and the first competitive examination system for entry to the Indian Civil Service — the structural predecessor of Pakistan's FPSC
It established the first merit-based promotion system and abolished seniority-based advancement — a principle reversed by subsequent Pakistani governments

Correct Answer Logic:

The Government of India Act 1935 introduced two landmark protections: security of tenure (no dismissal without due process, including right of appeal up to Secretary of State) and provincial financial autonomy. The security of tenure principle became foundational to civil service independence in Pakistan — codified in the Civil Servants Act 1973 — while provincial financial autonomy laid conceptual groundwork for federalism and NFC-type resource-sharing mechanisms.
