Question 122
For steady 1D conduction through a cylindrical wall (inner radius \(r_1\), outer radius \(r_2\), length \(L\), conductivity \(k\)), the thermal resistance is:
  • \(R_{cyl} = \frac{r_2 - r_1}{2\pi r L k}\)
  • \(R_{cyl} = \frac{\ln(r_2/r_1)}{2\pi L k}\)✔️
  • \(R_{cyl} = \frac{2\pi L k}{\ln(r_2/r_1)}\)
  • \(R_{cyl} = \frac{r_2^2 - r_1^2}{2kL}\)
Correct Answer Logic:
For a hollow cylinder: \(R_{cyl}=\ln(r_2/r_1)/(2\pi Lk)\). Temperature varies logarithmically, not linearly as in the plane wall.

Correct Answer Logic:

This two-blank question requires understanding the critical tone of the passage.

Blank (i): The agency never defined “untenable risk,” leaving it without a firm standard. This absence of a standard made it open and vulnerable to outside influence. Susceptible to means vulnerable or open to — exactly right. “Unaware of” doesn’t explain the influence, and “irritated at” changes the meaning entirely.

Blank (ii): Experts reacted negatively to the agency’s poor decision. They would pan it — meaning to criticize harshly. “Complimented” is the opposite, and “overlooked” means to ignore, not to criticize.

Correct Answers: Blank (i) = A (susceptible to), Blank (ii) = E (panned).

Correct Answer Logic:

Resistivity ($\rho$) is the reciprocal of conductivity ($\sigma$).

$\sigma = ne\mu_e$

Given: $n = 10^{19} \text{ m}^{-3}$, $\mu_e = 1.6 \text{ m}^2/\text{Vs}$, and $e = 1.6 \times 10^{-19} \text{ C}$.

$\sigma = 10^{19} \times (1.6 \times 10^{-19}) \times 1.6 = 1.6 \times 1.6 = 2.56 \ \Omega^{-1}\text{m}^{-1}$.

$\rho = \frac{1}{\sigma} = \frac{1}{2.56} \approx 0.39 \ \Omega\text{m}$.

The closest value provided is $0.4 \ \Omega\text{m}$.

Education QUESTION #6749
Question 137
In Classical Test Theory (CTT), the observed score of a student is represented as: Observed Score = True Score + Error. Which of the following scenarios would MOST increase the error component of a student's observed score?
  • The test items are arranged from easy to difficult
  • The test is administered in a noisy room with poor lighting and students experience test anxiety✔️
  • The teacher uses a two-way table of specification to develop the test
  • The test includes both objective and subjective items
Correct Answer Logic:
Error in CTT refers to any factor beyond the student's true ability that affects the observed score. Poor environmental conditions (noise, lighting) and test anxiety are classic sources of construct-irrelevant variance that inflate the error component, making the observed score a less accurate reflection of true ability.
