Question 5

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

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

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

Law QUESTION #9521

Question 10

A civil suit is decreed in favour of A. B files an appeal, which is admitted. During the appeal, both parties enter a compromise settling all claims. The appellate Court is asked to pass a decree in terms of the compromise under Order XXIII Rule 3. B later argues the compromise was made under coercion and seeks to have it set aside. How should B proceed?

Apply within the same proceedings before the appellate Court to show that the compromise was not lawful, since Order XXIII Rule 3 CPC requires the Court to be satisfied that the compromise is lawful before recording it✔️
File a revision petition before the High Court
File a criminal complaint for coercion
File a separate suit to set aside the compromise

Correct Answer Logic:

Order XXIII Rule 3 CPC requires the Court to be satisfied that a compromise is not unlawful before recording it. If B can show that the compromise was made under coercion or duress, he can raise this before the same Court which was asked to pass the compromise decree. The Court investigates the validity of the compromise before making it a rule of the Court.

Question 11

Which of the following is a WRONG statement about nitrogen's atomic properties?

The electronic configuration of N has incorrect spin assignment in 2p orbitals as shown✔️
An orbital is designated by three quantum numbers; an electron by four
Total orbital angular momentum of an electron in s orbital equals zero
The value of $m$ for $d_{z^2}$ orbital is zero

Correct Answer Logic:

Hund's Rule: In the nitrogen atom, 2p subshell has 3 electrons — each goes into a separate orbital with parallel spins (↑↑↑), NOT with one paired. If the diagram shows pairing in 2p before all orbitals are singly occupied, it violates Hund's rule and is wrong.

Options (2), (3), and (4) are all correct statements. Angular momentum of s-electron = $\sqrt{\ell(\ell+1)}\cdot\dfrac{h}{2\pi} = 0$ since $\ell=0$.

Question 13

If a normal person marries with a colour blind female, what will be the possibility of a normal male child?

0%✔️
25%
50%
75%

Correct Answer Logic:

A colour blind female has genotype $X^c X^c$. A normal male has genotype $X^N Y$. All sons receive $X^c$ from mother and $Y$ from father, making all sons colour blind ($X^c Y$). So 0% chance of a normal male child.

Administration QUESTION #9601

Question 14

A company's current ratio is 2.5 but its quick ratio is 0.6. What does this disparity most critically reveal about the company's liquidity position, and what risk does it pose to short-term creditors?

The company is in excellent liquidity health — a current ratio above 2.0 always signals strong ability to meet short-term obligations
The company's liquidity is heavily dependent on inventory — if inventory cannot be quickly liquidated (due to obsolescence, market conditions or long conversion cycles), the company may be unable to meet current obligations despite appearing liquid on paper✔️
The company has excessive cash holdings that are suppressing the quick ratio — it should invest idle cash in short-term securities
The disparity indicates aggressive revenue recognition — the company is booking receivables before cash collection, inflating current assets artificially

Correct Answer Logic:

Current ratio includes inventory; quick ratio excludes it. A current ratio of 2.5 with a quick ratio of 0.6 means nearly all current assets are inventory. If inventory is slow-moving, seasonal or perishable, it cannot reliably convert to cash in time to meet current liabilities. This is precisely the risk creditors face — apparent liquidity that evaporates when inventory cannot be sold, a common precursor to liquidity crises in retail and manufacturing firms.

Question 15

If the horizontal range of a projectile becomes half of its maximum possible horizontal range, the probable angle of projection is:

$15°$✔️
$30°$
$45°$
$60°$

Correct Answer Logic:

Maximum range occurs at $45°$: $R_{max} = \dfrac{v^2}{g}$. Range at angle $\theta$: $R = \dfrac{v^2\sin2\theta}{g}$. For $R = \dfrac{R_{max}}{2}$: $\sin2\theta = \dfrac{1}{2}$, so $2\theta = 30°$ or $150°$, giving $\theta = 15°$ or $75°$. The smallest angle is $15°$.

Question 16

The Trapezoidal Rule for $n$ equally spaced points with step size $h$ is:

$\dfrac{h}{2}(y_0+2y_1+\cdots+2y_{n-1}+y_n)$✔️
$\dfrac{h}{3}(y_0+4y_1+2y_2+\cdots+y_n)$
$h(y_0+y_1+\cdots+y_n)$
$\dfrac{h}{2}(y_0+y_n)$

Correct Answer Logic:

The Trapezoidal Rule approximates $\int_a^b f(x)\,dx\approx\dfrac{h}{2}[f(x_0)+2f(x_1)+2f(x_2)+\cdots+2f(x_{n-1})+f(x_n)]$. This gives the first and last function values weight 1 and all interior values weight 2.

Nursing QUESTION #9151

Question 20

A Head Nurse is planning a vaccination drive. Which of the following cold chain temperatures is correct for storing oral polio vaccine (OPV)?

Between +2°C and +8°C
Between -15°C and -25°C✔️
Between 0°C and +4°C
Between +8°C and +15°C

Correct Answer Logic:

The Oral Polio Vaccine (OPV) is the most heat-sensitive of all vaccines used in the Expanded Programme on Immunization (EPI). It must be stored at -15°C to -25°C at the national and provincial level. However, at the district/peripheral level, OPV can be stored at +2°C to +8°C for short periods. The option -15°C to -25°C is the standard cold chain requirement. Mismanagement of cold chain is a leading cause of vaccine failure — a Head Nurse must strictly monitor this.
