Electrical Engineering QUESTION #2160
Question 1426
A signal $x(t) = 5\cos(200\pi t) + 3\sin(400\pi t)$ is sampled at $f_s = 300\,\text{Hz}$. Which frequency component(s) experience aliasing?
  • Both $100\,\text{Hz}$ and $200\,\text{Hz}$✔️
  • $100\,\text{Hz}$ only
  • $200\,\text{Hz}$ only
  • No aliasing occurs
Correct Answer Logic:
The two components have frequencies $100\,\text{Hz}$ and $200\,\text{Hz}$. The Nyquist limit is $f_s/2 = 150\,\text{Hz}$. Since both exceed $150\,\text{Hz}$, both components alias.

Law QUESTION #9529
Question 1427
A decree for possession of land is passed in favour of A. A dies before execution. A's son S, who is a Hindu undivided family co-parcener, seeks execution. B the judgment-debtor argues S must obtain probate or letters of administration before being recognised as A's representative. Is B's contention correct?
  • No; S can only execute the decree if he obtains a succession certificate
  • Yes; S must first obtain probate
  • Yes; execution requires a court certificate of inheritance
  • No; in the absence of a specific requirement, S can apply to the executing Court to be recognised as the legal representative of A under Section 50 CPC; the executing Court has jurisdiction to determine who constitutes the legal representative without requiring formal probate in every case✔️
Correct Answer Logic:
Section 50 CPC allows the executing Court to permit execution against the legal representative of a deceased decree-holder. 'Legal representative' is defined broadly under Section 2(11) to include any person who in law represents the estate. The executing Court can determine the question of legal representation without insisting on formal probate in every case.

Civil Engineering QUESTION #6610
Question 1430
For a steel plate under tension with staggered holes, the 'net area' ($A_n$) calculation uses the $s^2/4g$ correction factor. What do $s$ and $g$ represent?
  • s = span, g = gap
  • s = longitudinal pitch, g = transverse gage✔️
  • s = size of bolt, g = grade of steel
  • s = stress, g = gravity
Correct Answer Logic:
When paths are staggered, the net width is reduced by the hole diameters and increased by $s^2/4g$ for each diagonal segment, where $s$ is the longitudinal spacing (pitch) and $g$ is the transverse spacing (gage).

Chemistry QUESTION #1440
Question 1433
What type of fragmentation occurs in mass spectrometry?
  • Homolytic cleavage✔️
  • Heterolytic cleavage
  • Both (A) and (B)
  • None of these
Correct Answer Logic:
In mass spectrometry, the primary fragmentation mechanism is homolytic cleavage (homolysis), where a bond breaks such that each fragment retains one electron from the bond, forming radical cations. This is because the ionisation process (electron bombardment in EI-MS) produces radical cations. Heterolytic cleavage (both electrons to one fragment) can also occur in some rearrangements, but homolytic cleavage is the predominant mode.

Correct Answer Logic:
This statement is false. The correct protocol is for the auditor to promptly report the irregularity or suspected illegal act to a level of management one tier above where the activity occurred. If the suspected activity involves those responsible for internal controls, the matter should be escalated to the highest available level of management — typically the audit committee. The auditor should never contact law enforcement directly unless specifically advised to do so by their own legal counsel.

$n = 2^3 = 8$.

$n^n = 8^8 = (2^3)^8 = 2^{3 \times 8} = 2^{24}$.

Answer: $\mathbf{2^{24}}$.
