Accounting & Finance QUESTION #6152

Cutting department data — Budget: Overheads $40,000; Machine hours 2,800; Labour hours 2,600. Actual: Overheads $44,000; Machine hours 2,700; Labour hours 2,900. What OAR would have been used?

$14.29 per machine hour
$15.17 per labour hour
$15.38 per labour hour✔️
$16.30 per machine hour

Correct Answer Logic:

Option C ($15.38 per labour hour) is correct.

OAR uses budgeted figures: $40,000 ÷ 2,600 budgeted labour hours = $15.38 per labour hour.

Labour hours are the more appropriate basis as actual labour hours (2,900) exceed actual machine hours (2,700), indicating a labour-intensive department.

Dairy Food Science and Technology QUESTION #5998

Question 3

In dairy plant design, 'zoning' of a dairy processing facility correctly describes:

Placing all refrigeration units in one zone
Separating the facility into distinct areas (raw milk zone, processing zone, pasteurized product zone, packaging zone) with controlled access, airflow, and dedicated equipment/personnel to prevent cross-contamination✔️
Designing all processing equipment in a linear flow
Locating all CIP systems in the highest-risk zone

Correct Answer Logic:

Hygienic zoning in dairy plants separates: (1) Raw material/dirty areas (raw milk reception); (2) Processing/intermediate risk (pasteurization, separation); (3) Pasteurized/clean areas (filling, packaging); (4) High-care/clean rooms. Each zone has controlled access, appropriate hygiene level (GMP, HACCP), unidirectional flow of product/personnel/air, and distinct waste management.

Federal Rules of Evidence (US) QUESTION #3790

Question 7

A defendant is on trial for possession of stolen property. He testifies in his own defense. On cross-examination, the prosecutor asks, 'Isn't it true that you lied on your last two tax returns?' The defendant has never been convicted of tax fraud. Is the question permitted?

No, because there was no conviction.
Yes, because Rule 608(b) allows inquiry into specific instances of conduct on cross-examination if they are probative of the witness's character for truthfulness.✔️
No, because it is 'extrinsic evidence.'
Yes, but only if the defendant first introduced evidence of his own good character.

Correct Answer Logic:

Rule 608(b) allows a court to permit cross-examination into specific instances of conduct (even without conviction) if they are probative of the witness's character for truthfulness or untruthfulness.

Chemistry QUESTION #5582

Question 12

In a reaction sequence, sodium phenoxide reacts with $CO_2$ under pressure at 125°C (Kolbe–Schmitt reaction) to give B, which on acetylation with $Ac_2O$ gives C. What is the major product C?

Methyl salicylate (OH and $COOCH_3$ on ring)
Ortho-acetoxybenzoic acid ($OCOCH_3$ and $COOH$ ortho)✔️
Para-acetoxybenzoic acid ($OCOCH_3$ and $COOH$ para)
A compound with keto groups

Correct Answer Logic:

Kolbe–Schmitt reaction: Sodium phenoxide + $CO_2$ (125°C, 5 atm) → Sodium salicylate (2-hydroxybenzoate), acidified to give salicylic acid (B = 2-hydroxybenzoic acid). Acetylation of salicylic acid with $Ac_2O$ preferentially acetylates the –OH group → product C = 2-(acetyloxy)benzoic acid = aspirin (ortho-acetoxybenzoic acid).

Physics QUESTION #7044

Question 15

Beams A and B are plane-polarised with perpendicular planes. Initially, a polaroid shows maximum intensity for A and zero for B. Rotating the polaroid by $30^\circ$ makes them look equally bright. Find the ratio of their initial intensities $\frac{I_A}{I_B}$.

$1$
$\frac{1}{3}$✔️
$3$
$\frac{3}{2}$

Correct Answer Logic:

Initially, beam A's plane is parallel to the polaroid ($\theta_A = 0^\circ$) and B's is perpendicular ($\theta_B = 90^\circ$).

After $30^\circ$ rotation, the angles become $30^\circ$ and $60^\circ$ respectively.

Equal brightness means: $I_A \cos^2(30^\circ) = I_B \cos^2(60^\circ)$

$I_A \left( \frac{\sqrt{3}}{2} \right)^2 = I_B \left( \frac{1}{2} \right)^2 \implies I_A \cdot \frac{3}{4} = I_B \cdot \frac{1}{4} \implies \frac{I_A}{I_B} = \frac{1}{3}$.

Question 16

A particle starts from the origin (0, 0) and moves in a straight line. At a later time its position is $(\sqrt{3},\,3)$. The angle the path makes with the positive $x$-axis is:

$0°$
$30°$
$45°$
$60°$✔️

Correct Answer Logic:

$\tan\alpha = \dfrac{y}{x} = \dfrac{3}{\sqrt{3}} = \sqrt{3}$

$\alpha = \tan^{-1}(\sqrt{3}) = \mathbf{60°}$

Electrical Engineering QUESTION #2145

Question 19

A system is described by the transfer function $H(s) = \frac{10}{s^2 + 2s + 10}$. What is the natural frequency $\omega_n$ of this system?

$10\text{ rad/s}$
$\sqrt{10}\text{ rad/s}$✔️
$2\text{ rad/s}$
$5\text{ rad/s}$

Correct Answer Logic:

Comparing with the standard form $\frac{\omega_n^2}{s^2 + 2\zeta\omega_n s + \omega_n^2}$, we see $\omega_n^2 = 10$, so $\omega_n = \sqrt{10}\text{ rad/s}$.
