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?
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.

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?
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).

QUESTION #1440
Question 1433
What type of fragmentation occurs in mass spectrometry?
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.
