Dairy Food Science and Technology QUESTION #5901

Question 3

Diacetyl, the primary butter flavor compound, is produced by which metabolic pathway?

Lactose fermentation via glycolysis directly
Citrate fermentation by $Leuconostoc\;mesenteroides$ and $Lactococcus\;lactis$ subsp. $lactis$ biovar $diacetylactis$: citrate $\rightarrow$ pyruvate $\rightarrow$ $\alpha$-acetolactate $\rightarrow$ diacetyl✔️
Proteolysis of casein releasing sulfur compounds
Lipolysis releasing short-chain fatty acids

Correct Answer Logic:

Diacetyl (2,3-butanedione) is the key aroma compound in cultured butter and sour cream. It is produced from citrate (present in milk at $\approx 8\;\text{mM}$) via: citrate $\rightarrow$ pyruvate $\rightarrow$ $\alpha$-acetolactate $\rightarrow$ diacetyl.

Electrical Engineering QUESTION #2181

Question 7

An op-amp integrator has $R = 10\,\text{k}\Omega$ and $C = 0.1\,\mu\text{F}$. The input is a $\pm1\,\text{V}$ square wave at $1\,\text{kHz}$. The peak-to-peak output voltage is:

$0.5\,\text{V}$✔️
$1.0\,\text{V}$
$2.0\,\text{V}$
$0.25\,\text{V}$

Correct Answer Logic:

$RC = 10^4 \times 10^{-7} = 1\,\text{ms}$. Each half-period $T/2 = 0.5\,\text{ms}$. Output ramp amplitude $\Delta V = \frac{V_{in}\cdot(T/2)}{RC} = \frac{1\times0.5\times10^{-3}}{10^{-3}} = 0.5\,\text{V}$. Since the output ramps up then down symmetrically, peak-to-peak $= 0.5\,\text{V}$.

Physics QUESTION #7083

Question 9

A solid sphere (radius $r$, bulk modulus $K$) is in a liquid. A mass $m$ is placed on a piston of area $a$ to compress the liquid. Find the fractional decrease in radius $\frac{dr}{r}$.

$\frac{mg}{3Ka}$✔️
$\frac{mg}{Ka}$
$\frac{Ka}{mg}$
$\frac{3Ka}{mg}$

Correct Answer Logic:

Bulk Modulus $K = \frac{\Delta P}{-\Delta V/V}$.

The change in pressure is $\Delta P = \frac{mg}{a}$.
The fractional change in volume for a sphere is $\frac{\Delta V}{V} = 3\frac{dr}{r}$.
$K = \frac{mg/a}{3dr/r} \implies \frac{dr}{r} = \frac{mg}{3Ka}$.

Physics QUESTION #1153

Question 12

The zeroth law of thermodynamics helps to define the term:

Temperature✔️
Pressure
Volume
Density

Correct Answer Logic:

The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law provides the basis for defining and measuring temperature.

Chemistry QUESTION #7522

Question 13

The vapour pressure of pure acetone at 20°C is 185 torr. When 1.2 g of a non-volatile solute is dissolved in 100 g of acetone, the vapour pressure drops to 183 torr. Find the molar mass of the solute (g mol$^{-1}$).

32
64
128✔️
488

Correct Answer Logic:

Using Raoult's Law: $\dfrac{P^0 - P}{P^0} = x_{\text{solute}}$

$\dfrac{185 - 183}{185} = \dfrac{1.2/M}{(1.2/M) + (100/58)}$

$\dfrac{2}{185} = x_{\text{solute}}$

Since $1.2/M \ll 100/58$, approximate: $x_{\text{solute}} \approx \dfrac{1.2/M}{100/58} = \dfrac{1.2 \times 58}{100M}$

$\dfrac{2}{185} = \dfrac{69.6}{100M}$

$M = \dfrac{69.6 \times 185}{200} = \dfrac{12876}{200} \approx \mathbf{128\ \text{g mol}^{-1}}$

Tourism & Hospitality Management QUESTION #1613

Question 14

The Tourism and Hospitality Laws course addresses 'the law of tort' as relevant to hospitality operations. Which of the following scenarios would most directly engage tort law in a hotel context?

A hotel failing to renew its business registration on time
A guest slipping on an unmarked wet floor in the hotel lobby and sustaining injury due to the hotel's negligence✔️
A chef preparing food that does not meet a guest's flavor preference
A hotel raising its room rates during peak season

Correct Answer Logic:

The Tourism and Hospitality Laws course covers torts — specifically negligence, trademark infringement, and fraud — in Module 2. A guest injured due to the hotel's failure to maintain safe premises (e.g., an unmarked wet floor) is a classic negligence tort scenario in which the hotel owes a duty of care and may be held liable for breach of that duty.

Verbal Reasoning QUESTION #8114

Question 18

If $x > 0$ and $y > 0$, which of the following is equivalent to $\dfrac{x}{y}\sqrt{\dfrac{y}{x^2}}$?

$1$
$\dfrac{\sqrt{x}}{\sqrt{y}}$
$\sqrt{x}$
$\dfrac{1}{\sqrt{y}}$✔️

Correct Answer Logic:

Simplify step by step:

$\dfrac{x}{y} \cdot \sqrt{\dfrac{y}{x^2}} = \dfrac{x}{y} \cdot \dfrac{\sqrt{y}}{\sqrt{x^2}} = \dfrac{x}{y} \cdot \dfrac{\sqrt{y}}{x} = \dfrac{\sqrt{y}}{y} = \dfrac{1}{\sqrt{y}}$

The answer is $\dfrac{1}{\sqrt{y}}$.
