Chemistry QUESTION #7185

Question 3

In a specific gas mixture, the mass ratio of oxygen to nitrogen is $1:4$. What is the ratio of the number of molecules of oxygen to nitrogen in this mixture?

$1:8$
$3:16$
$1:4$
$7:32$✔️

Correct Answer Logic:

The number of molecules is proportional to the number of moles ($n = \text{mass} / \text{Molar mass}$):

Let mass of $O_{2} = w$ and mass of $N_{2} = 4w$.
Moles of $O_{2} = w / 32$.
Moles of $N_{2} = 4w / 28 = w / 7$.
Ratio of molecules = $(w/32) : (w/7) = 7 : 32$.

HR and Management QUESTION #6464

Question 4

When the text mentions 'labor cost is often considerably higher than necessary' due to personnel problems, it refers to:

Excessive base salary rates in the market
Absenteeism, tardiness, and discrimination issues✔️
Overstaffing in all departments
Generous benefits packages

Correct Answer Logic:

Labor costs are higher than necessary due to problems like absenteeism, tardiness, and discrimination - all preventable through effective HRM. These issues create waste and inefficiency beyond the direct salary costs.

Physics QUESTION #1173

Question 5

Alpha particles and electrons having the same energy — their associated De Broglie wavelengths are:

Equal
Longer than electrons (alpha has longer wavelength)
Smaller than electrons (alpha has shorter wavelength)✔️
None of these

Correct Answer Logic:

De Broglie wavelength: $\lambda = \frac{h}{\sqrt{2mE}}$. At the same kinetic energy $E$, $\lambda \propto \frac{1}{\sqrt{m}}$. Since $m_\alpha \gg m_e$ (alpha particle is ~7294 times heavier), $\lambda_\alpha \ll \lambda_e$. So alpha particles have a much shorter De Broglie wavelength than electrons at the same energy.

Question 6

The distance of a point $(10, -10)$ from origin is:

$10\sqrt{2}$✔️
10
15
None

Correct Answer Logic:

Distance $= \sqrt{10^2 + (-10)^2} = \sqrt{100 + 100} = \sqrt{200} = 10\sqrt{2}$.

None of these

Correct Answer Logic:

TQM is a holistic approach that seeks to improve quality through the ongoing involvement of all employees and departments.

Agronomy QUESTION #2107

Question 11

Soil organic carbon (SOC) sequestration through agricultural management contributes to climate change mitigation because:

SOC increases soil pH, which directly reduces methane emissions from paddy soils
Increasing SOC stocks through reduced tillage, organic amendments, cover crops, and biochar additions removes CO₂ from the atmosphere and stores it in stable soil organic matter pools — partially offsetting agricultural GHG emissions while also improving soil health and productivity✔️
SOC sequestration is exclusively achieved through afforestation and has no relevance to cropland management
Higher SOC concentrations accelerate denitrification, converting harmful $NO_3^-$ to inert $N_2$

Correct Answer Logic:

Agricultural soils have lost 50–70% of their original SOC through tillage, erosion, and oxidation. Conservation tillage, organic matter additions, cover cropping, and biochar can rebuild SOC stocks. Each 1% increase in SOC in the top 30 cm represents ~25 t CO₂-equivalent per hectare sequestered. The '4 per 1000' initiative proposes 0.4% annual SOC increase globally to offset anthropogenic CO₂ emissions — highlighting cropland SOC management as a climate mitigation strategy.

Administration QUESTION #9549

Question 12

The Atchison Commission (1886-87) made a critical recommendation regarding the structure of British India's civil service. What was the practical governance problem it sought to solve, and what institutional solution did it propose?

It sought to correct the dominance of generalists over specialists by recommending that technical civil servants be eligible for senior administrative positions
It sought to eliminate the distinction between covenanted and un-covenanted servants — which created unequal treatment — by recommending establishment of a unified Imperial Civil Service✔️
It sought to reduce corruption in tax collection by recommending that revenue administration be separated from general district administration
It sought to address regional underrepresentation by recommending that entry to the Indian Civil Service be opened to candidates from the sub-continent regardless of religion or race

Correct Answer Logic:

The Atchison Commission identified the inequitable and arbitrary distinction between higher-grade covenanted servants (who signed agreements) and lower-grade un-covenanted servants (who had no protection). It recommended abolishing this distinction and establishing a unified 'Imperial Civil Service' (later 'Indian Civil Service') with standardized terms of service.

Electrical Engineering QUESTION #2153

Question 13

In Power Electronics, a Freewheeling Diode is used in an inductive load circuit to:

Increase the output voltage
Prevent high-voltage spikes $L\frac{di}{dt}$ during turn-off✔️
Rectify the AC input
Smooth the ripple in the capacitor

Correct Answer Logic:

The diode provides a path for the inductive current to continue flowing when the switch opens, preventing damaging $L\frac{di}{dt}$ voltage spikes.

Law QUESTION #9520

Question 16

A suit for dissolution of a firm is filed. The trial Court appoints a receiver to manage the firm's affairs pending the suit. The receiver, acting in that capacity, enters into a contract with a third party T. T later sues the firm for breach of this contract. The firm argues T should have sued the receiver personally. Is the firm liable?

Yes; but only the Court can be sued for the receiver's acts
Yes; a receiver acts as an officer of the Court and on behalf of the parties; contracts entered into by the receiver in the ordinary course of managing the firm may bind the firm and the estate under receivership, subject to the terms of the Court's order✔️
No; T should have obtained the Court's leave before contracting with the receiver
No; the receiver acts in personal capacity alone

Correct Answer Logic:

Under Order XL CPC, a receiver is an officer of the Court appointed to preserve and manage property. He acts under the Court's authority and for the benefit of the estate. Contracts entered in the ordinary course by the receiver in managing the firm bind the estate. Third parties dealing with the receiver in good faith may proceed against the assets of the estate.

Question 19

Which one of the following is a depositional landform of a river?

Alluvial Fans✔️
Waterfall
Potholes
None of these

Correct Answer Logic:

Alluvial fans are depositional landforms formed where a river emerges from a mountain or valley onto a plain, losing velocity and depositing its load in a fan-shaped spread. Waterfalls and potholes are erosional landforms formed by the cutting action of rivers. Alluvial fans, floodplains, and deltas are all depositional landforms.
