Chemistry QUESTION #7373

The energy of an electron in the $2p_y$ orbital compared to other orbitals is:

Greater than $2p_x$
Less than $2p_z$
Same as $2p_x$ and $2p_z$✔️
Equal to 2s orbital

Correct Answer Logic:

Degeneracy of p-orbitals:
The three p-orbitals $(2p_x, 2p_y, 2p_z)$ are degenerate — they have exactly the same energy. This is because energy depends only on the quantum numbers $n$ and $\ell$ (in the absence of external fields). The magnetic quantum number $m$ distinguishes their spatial orientation, not their energy.

Energy degeneracy is lifted in the presence of magnetic (Zeeman effect) or electric (Stark effect) fields.

CISA QUESTION #1732

Question 2864

Within a business organisation, which tier of personnel is typically held legally liable by government authorities for failures in internal control?

President, vice presidents, and all formally designated corporate officers✔️
Board of directors, president, vice presidents, department directors, and all managers
Every member of management without exception
Board of directors, CEO, CFO, CIO, and department directors

Correct Answer Logic:

Government regulators generally hold true corporate officers — those holding titles of vice president and above within the parent organisation — legally accountable for internal control failures. A CIO at division level may or may not qualify as a true corporate officer. Department directors and their subordinates are generally not personally liable to government authorities for control failures; they support the vice presidents above them in the governance hierarchy.

Law QUESTION #9486

Question 2865

A decree-holder A wishes to attach a sum of Rs. 500,000 kept in a bank account belonging to the judgment-debtor B, which was earned by B as salary and deposited over time. B argues that salary is exempt from attachment. Can the bank balance representing accumulated salary be attached?

Yes; once salary has been received and deposited in a bank account, it loses its character as salary and becomes an ordinary debt recoverable from the bank, which is attachable✔️
Yes; but only with the permission of the State Bank of Pakistan
No; bank accounts can never be attached in execution
No; salary retains its exempt character even after being deposited in a bank

Correct Answer Logic:

The exemption under Section 60(1)(i) CPC applies to salary before and until it is actually payable; once salary has been paid and deposited in a bank, it is converted into a debt due from the bank and loses its exempt character, becoming attachable in execution.

Physics QUESTION #7066

Question 2871

A cube of maximum possible volume is cut from a solid sphere of mass $M$ and radius $R$. Find the moment of inertia of this cube about an axis that passes through its center and is perpendicular to one of its faces.

$\frac{MR^2}{32\sqrt{2}\pi}$
$\frac{MR^2}{16\sqrt{2}\pi}$
$\frac{4 MR^2}{9\sqrt{3}\pi}$✔️
$\frac{4 MR^2}{3\sqrt{3}\pi}$

Correct Answer Logic:

1. Find Cube Side ($a$): The body diagonal of the cube equals the diameter of the sphere. $\sqrt{3}a = 2R \implies a = \frac{2R}{\sqrt{3}}$.

2. Find Cube Mass ($m$): Density $\rho = \frac{M}{\frac{4}{3}\pi R^3}$. Mass of cube $m = \rho \times a^3 = \left(\frac{3M}{4\pi R^3}\right) \times \left(\frac{8R^3}{3\sqrt{3}}\right) = \frac{2M}{\pi \sqrt{3}}$.

3. Moment of Inertia ($I$): For a cube about the center-face axis, $I = \frac{ma^2}{6}$.
$I = \frac{1}{6} \left( \frac{2M}{\pi \sqrt{3}} \right) \left( \frac{4R^2}{3} \right) = \frac{8MR^2}{18\pi \sqrt{3}} = \frac{4MR^2}{9\sqrt{3}\pi}$.

General Knowledge QUESTION #2622

Question 2872

Which of the following CORRECTLY describes the difference between HDMI and DVI cables?

HDMI outputs only video while DVI outputs both video and audio
HDMI outputs both video and audio while DVI generally outputs video only✔️
Both HDMI and DVI output only video without any audio
Both HDMI and DVI output both audio and video identically

Correct Answer Logic:

HDMI (High Definition Multimedia Interface) outputs BOTH video and audio through a single cable. DVI (Digital Visual Interface) cables generally output VIDEO ONLY. This makes HDMI more practical for connecting computers to monitors and TVs with speakers.

Statistics QUESTION #1973

Question 2878

For a paired t-test conducted on $n$ matched pairs of observations, the appropriate degrees of freedom is:

$2n - 1$
$n - 2$
$2(n - 1)$
$n - 1$✔️

Correct Answer Logic:

In a paired t-test, the $n$ differences $d_i = X_{1i} - X_{2i}$ are treated as a single sample. The degrees of freedom is therefore $n - 1$, just as for a one-sample t-test.

Question 2879

The Muslims conquered Mecca in:

620 A.D
625 A.D
630 A.D✔️
635 A.D

Correct Answer Logic:

The Muslims conquered Makkah in 630 CE (8 AH). This peaceful conquest occurred after the Quraish violated the Treaty of Hudaybiyah. The Prophet (PBUH) entered Makkah with 10,000 companions. He granted general amnesty to the Meccans, destroyed the idols in the Kaaba, and forgave his former enemies, demonstrating the Islamic principles of mercy and forgiveness. This conquest marked a turning point, leading to the rapid spread of Islam throughout Arabia.
