Question 3
A wire stretches by $0.04\text{ m}$ under force $F$. What is the elongation if length and diameter are doubled under the same force?
Correct Answer Logic:
Elongation $\Delta L = \frac{FL}{AY} = \frac{FL}{\pi(d/2)^2 Y} \propto \frac{L}{d^2}$.
- New elongation $\Delta L' \propto \frac{2L}{(2d)^2} = \frac{2L}{4d^2} = \frac{1}{2} \Delta L$
- $\Delta L' = \frac{1}{2} \times 0.04 = 0.02\text{ m}$.

Question 7
The liquefied metal that expands on solidification is:
Correct Answer Logic:
Gallium (Ga) is one of the few substances (like water and bismuth) that expands on solidification. This is due to its unusual crystal structure in the solid state, where Ga–Ga covalent bonds result in a less dense solid than the liquid. Gallium has a very low melting point (29.76°C) and is liquid at or slightly above room temperature.

Correct Answer Logic:
Reaction (a): \(\text{H}_2\text{O}_2\) is oxidised to \(\text{O}_2\) (oxygen goes from \(-1\) to \(0\) oxidation state) → \(\text{H}_2\text{O}_2\) acts as reducing agent
Reaction (b): \(\text{Ag}_2\text{O}\) is reduced to Ag (\(\text{Ag}^+\) → \(\text{Ag}^0\)) while \(\text{H}_2\text{O}_2\) provides oxygen → \(\text{H}_2\text{O}_2\) acts as oxidising agent
\(\text{H}_2\text{O}_2\) is amphoteric (can act as both oxidant and reductant depending on partner).
Reaction (b): \(\text{Ag}_2\text{O}\) is reduced to Ag (\(\text{Ag}^+\) → \(\text{Ag}^0\)) while \(\text{H}_2\text{O}_2\) provides oxygen → \(\text{H}_2\text{O}_2\) acts as oxidising agent
\(\text{H}_2\text{O}_2\) is amphoteric (can act as both oxidant and reductant depending on partner).

Question 10
Public Choice Theory is best described as an economic explanation of:
Correct Answer Logic:
Public Choice Theory applies economic methods and assumptions (rational self-interest, utility maximization) to political decision-making. Associated with James Buchanan (Nobel Laureate) and Gordon Tullock, it argues that politicians, bureaucrats, and voters behave as self-interested rational actors. This leads to phenomena like rent-seeking, government failure, and budget maximization by bureaucrats.

Correct Answer Logic:
Peopleware refers collectively to all human resources involved with computers — systems analysts, programmers, operators, and end users. Popularised by Tom DeMarco and Timothy Lister in Peopleware: Productive Projects and Teams (1987), it emphasises that human factors are as critical as hardware and software.

Question 17
Which test is performed to detect coliform bacteria in milk as an indicator of post-pasteurization contamination?
Correct Answer Logic:
Coliform bacteria (\(E.\;coli\), \(Klebsiella\), \(Enterobacter\)) should be absent or very low in properly pasteurized milk. Detection uses the MPN method (lauryl sulfate tryptose broth with gas production) or direct plating on selective media (VRBA, Petrifilm CC). Coliforms in pasteurized milk indicate post-pasteurization contamination.

Question 18
An organic compound A reacts with $NH_3$ to give B. On heating, B gives C. C reacts with $Br_2$/KOH to give $CH_3CH_2NH_2$ (ethylamine). Identify compound A.
Correct Answer Logic:
Working backwards: $CH_3CH_2NH_2$ (ethylamine) is produced by Hofmann bromamide degradation of $CH_3CH_2CONH_2$ (propionamide). Propionamide (C) is produced by heating propanoic acid ammonium salt (B). B is formed when $CH_3CH_2COOH$ (propanoic acid = A) reacts with $NH_3$. So A = $CH_3CH_2COOH$.

Question 19
The relation between half-life and mean life are:
Correct Answer Logic:
Half-life \(t_{1/2}\) and mean life \(\tau\) are related by: \(t_{1/2} = \tau \ln 2 = 0.693\,\tau\). Since \(t_{1/2} = 0.693\,\tau\), they are directly proportional to each other (one is always a fixed constant times the other). The half-life is always shorter than the mean life by a factor of \(\ln 2\).

Question 20
Change the voice: Will she not have sung the song?
Correct Answer Logic:
When changing from active to passive voice, the object becomes the subject. The structure 'Will...not have sung' (active) becomes 'Will...not have been sung' (passive). The agent 'by her' is added at the end.
