Electrical Engineering QUESTION #2190

A transmission line has $Z_1 = (0.4+j1.2)\,\Omega/\text{km}$ over $80\,\text{km}$. A distance relay's Zone-1 is set to protect $80\%$ of the line. The Zone-1 reach impedance magnitude is approximately:

$80.9\,\Omega$✔️
$64.0\,\Omega$
$101.2\,\Omega$
$50.0\,\Omega$

Correct Answer Logic:

$|Z_1/\text{km}| = \sqrt{0.4^2+1.2^2} = \sqrt{1.6} \approx 1.2649\,\Omega/\text{km}$. Total $|Z_{line}| = 80\times1.2649 \approx 101.2\,\Omega$. Zone-1 reach $= 0.8\times101.2 \approx 80.9\,\Omega$.

Chemistry QUESTION #7419

Question 6385

The biggest jump (gap) in electronegativity values occurs between which pair?

B → Al✔️
A → Ga
Ga → In
In → Tl

Correct Answer Logic:

Electronegativity in Group 13:
Electronegativity values (Pauling scale):

B: 2.04
Al: 1.61
Ga: 1.81
In: 1.78
Tl: 2.04

The largest drop occurs from B (2.04) to Al (1.61) — a difference of 0.43, which is the biggest gap. This is because B is a metalloid while Al is a true metal.

Mathematics QUESTION #1309

Question 6391

For $f(x)=x-\cos x$, the derivative $f'(x)$ used in Newton-Raphson is:

$1+\sin x$✔️
$1-\sin x$
$-\sin x$
$\cos x$

Correct Answer Logic:

$f(x)=x-\cos x\Rightarrow f'(x)=1+\sin x$. The Newton-Raphson iteration becomes: $x_{n+1}=x_n-\dfrac{x_n-\cos x_n}{1+\sin x_n}$. Starting near $x=\pi/4\approx0.7854$ converges to the root $\approx0.7391$.

The Constitution of Pakistan QUESTION #9361

Question 6392

Article 175E grants the Federal Constitutional Court exclusive original jurisdiction over disputes between Governments. The court's remedy in such cases is limited to:

Any appropriate remedy including injunctions
Declaratory judgments only✔️
Damages and compensation
Criminal sanctions against responsible officials

Correct Answer Logic:

Article 175E(2) explicitly provides that 'in the exercise of the jurisdiction conferred on it by clause (1), the Federal Constitutional Court shall pronounce declaratory judgments only.' This restricts the FCC's inter-governmental dispute remedy to declarations rather than coercive orders.

Question 6394

The maximum number of orbitals that can be identified with quantum numbers $n=3$, $\ell=1$, $m_\ell=0$ is:

1✔️
2
3
4

Correct Answer Logic:

For $n=3, \ell=1, m_\ell=0$: all three quantum numbers are fixed. This uniquely specifies one orbital — the $3p_z$ orbital (or whichever p-orbital corresponds to $m=0$). A specific orbital is defined by its set of $n$, $\ell$, and $m$. Only the spin quantum number $m_s$ remains free.

perhaps the most notable of the nearly 800 buildings in California designed by Julia Morgan was William Randolph Hearst's monumental estate at San Simeon
of the nearly 800 buildings in California designed by Julia Morgan, perhaps the most notable was William Randolph Hearst's monumental estate at San Simeon
nearly 800 buildings in California were designed by Julia Morgan, of which William Randolph Hearst's monumental estate at San Simeon is perhaps the most notable

Correct Answer Logic:

The introductory participial phrase 'A prolific architect…' must be followed by Julia Morgan as the grammatical subject to avoid a dangling modifier. Only option A does this. Options B, C, and D all shift the subject away from Julia Morgan, creating dangling modifiers.
