Education QUESTION #6778
Question 2824
A researcher applies Item Response Theory to a set of test items and finds that one item has a very low 'a' (discrimination) parameter and a relatively high 'c' (pseudo-guessing) parameter. What practical recommendation follows from this?
  • Retain the item because low guessing should be prioritized over discrimination
  • The item likely does not differentiate ability levels effectively and may be susceptible to correct responses through guessing; it should be revised or removed from the bank✔️
  • Increase the item difficulty to reduce the guessing parameter
  • Use this item as a warm-up item since it is accessible to all ability levels
Correct Answer Logic:
In IRT's 3-parameter logistic model: 'a' is discrimination (steepness of ICC), 'b' is difficulty, and 'c' is the pseudo-guessing parameter (lower asymptote of the ICC). A low 'a' means the item poorly differentiates ability levels; a high 'c' means even low-ability examinees have a substantial probability of answering correctly — suggesting guessing is inflating scores. Such items should be revised or dropped.

Correct Answer Logic:
Velocity before hitting: \(v_1 = \sqrt{2\times9.8\times40} = 28\ \text{m/s}\) (downward). Velocity after: \(v_2 = \sqrt{2\times9.8\times10} = 14\ \text{m/s}\) (upward). Impulse \(= m(v_2-(-v_1)) = 0.5\times(14+28) = 0.5\times42 = 21\ \text{NS}\).

Chemistry QUESTION #7351
Question 2828
Measurement of an electron's position introduces an uncertainty in momentum equal to \(1 \times 10^{-18}\) g cm s\(^{-1}\). The uncertainty in electron velocity (mass of electron \(= 9 \times 10^{-28}\) g) is:
  • \(1 \times 10^{11}\) cm s\(^{-1}\)
  • \(1 \times 10^{9}\) cm s\(^{-1}\)✔️
  • \(1 \times 10^{6}\) cm s\(^{-1}\)
  • \(1 \times 10^{5}\) cm s\(^{-1}\)
Correct Answer Logic:
Formula: \(\Delta v = \dfrac{\Delta p}{m}\)

\(\Delta v = \dfrac{1 \times 10^{-18}}{9 \times 10^{-28}} = \dfrac{1}{9} \times 10^{10} \approx 1 \times 10^9\) cm s\(^{-1}\)

This enormously large uncertainty in velocity illustrates why classical mechanics fails for electrons — they cannot have precisely defined trajectories.

Verbal Reasoning QUESTION #8098
Question 2829

Given that $r > s > 0$, compare the two quantities below.

Column A: $\dfrac{rs}{r}$

Column B: $\dfrac{rs}{s}$

  • Column A is greater
  • Column B is greater✔️
  • The two quantities are equal
  • The relationship cannot be determined from the information given
Correct Answer Logic:

Simplify each expression:

  • Column A: $\dfrac{rs}{r} = s$
  • Column B: $\dfrac{rs}{s} = r$

Since we are given $r > s > 0$, it follows that $r > s$.

Therefore Column B ($r$) is greater than Column A ($s$).

    Question 2838
    A Buyer orders 'Grade A' wheat. The Seller delivers 'Grade B' wheat. The Buyer notices the defect immediately but stays silent and uses the wheat. Can the Buyer later sue for breach?

    • No, because the Buyer accepted the goods by failing to reject them.✔️
    • Yes, but only if the Seller acted in bad faith.
    • No, because 'Grade B' is a reasonable substitute.
    Correct Answer Logic:
    Under UCC §2-602 and §2-606, failure to make an effective rejection after a reasonable opportunity to inspect signifies acceptance.

    Correct Answer Logic:
    Using the density formula $M = \frac{d \times N_A \times a^3}{Z}$:
    • $d = 9000\text{ kg/m}^3$
    • $Z = 4$ (for FCC)
    • $a = 200\sqrt{2} \times 10^{-12}\text{ m}$
    Calculation: $a^3 = (200\sqrt{2})^3 \times 10^{-36} = 1.6 \times 10^{-29}\text{ m}^3$.
    $M = \frac{9000 \times 6 \times 10^{23} \times 1.6 \times 10^{-29}}{4} = 0.0432\text{ kg mol}^{-1}$.

    Correct Answer Logic:

    Acidic medium (oxidising agent):
    $[\text{Fe(CN)}_6]^{4-} + H_2O_2 + 2H^+ \to [\text{Fe(CN)}_6]^{3-} + \text{H}_2\text{O}$
    H$_2$O$_2$ is reduced to H$_2$O. Other product: H$_2$O.

    Alkaline medium (reducing agent):
    $H_2O_2 \to H_2O + \frac{1}{2}O_2$ (H$_2$O$_2$ is oxidized)
    $2[\text{Fe(CN)}_6]^{3-} + H_2O_2 + 2OH^- \to 2[\text{Fe(CN)}_6]^{4-} + O_2 + 2H_2O$
    Other products: H$_2$O and O$_2$.

    So the pair is: H$_2$O (acidic) and (H$_2$O + O$_2$) (alkaline).
