Dairy Food Science and Technology QUESTION #5888

Question 224

Which milk protein fraction is most responsible for heat stability of milk?

$\beta$-casein due to its hydrophobic character
$\kappa$-casein due to its surface-active glycopeptide moiety stabilizing micelles✔️
$\alpha$-lactalbumin due to its calcium-binding domain
$\beta$-lactoglobulin due to disulfide bonding

Correct Answer Logic:

$\kappa$-casein, located on the outer surface of casein micelles, provides steric and electrostatic stabilization through its negatively charged hydrophilic glycomacropeptide (GMP) tail. Its removal by chymosin or denaturation during heating ($>70^{\circ}\text{C}$) destabilizes micelles.

Physics QUESTION #7057

Question 228

A $2 \text{ kg}$ sample of monoatomic gas is maintained at a pressure of $4 \times 10^4 \text{ N/m}^2$ with a density of $8 \text{ kg/m}^3$. What is the order of the gas's internal energy due to thermal motion?

$10^3 \text{ J}$
$10^5 \text{ J}$
$10^4 \text{ J}$✔️
$10^6 \text{ J}$

Correct Answer Logic:

The internal energy $U$ of a monoatomic gas is $U = \frac{3}{2} nRT = \frac{3}{2} PV$.

First, find the volume $V$ using mass and density: $V = \frac{\text{mass}}{\text{density}} = \frac{2}{8} = 0.25 \text{ m}^3$.

$U = \frac{3}{2} \times (4 \times 10^4) \times 0.25 = 1.5 \times 10^4 = 15000 \text{ J}$.

The order of magnitude is $10^4 \text{ J}$.

Electrical Engineering QUESTION #2173

Question 239

A half-wave dipole antenna has $R_{rad} = 73\,\Omega$, $R_{loss} = 7\,\Omega$, and directivity $D = 1.64$. Its radiation efficiency and gain are:

$\eta = 91.25\%$, $G \approx 1.497\,(1.75\,\text{dBi})$✔️
$\eta = 80\%$, $G = 1.31$
$\eta = 100\%$, $G = 1.64$
$\eta = 50\%$, $G = 0.82$

Correct Answer Logic:

$\eta = \frac{73}{73+7} = 0.9125 = 91.25\%$. $G = \eta \cdot D = 0.9125 \times 1.64 \approx 1.497 \approx 1.75\,\text{dBi}$.
