Chemistry QUESTION #7790

Question 1742

The enthalpy change $\Delta H$ can be measured indirectly using:

Avogadro's law
Faraday's law
Gas's law
Hess's law✔️

Correct Answer Logic:

Hess's law states that enthalpy change for a reaction is independent of path, allowing calculation of ΔH by summing known reactions.

Physics and Math QUESTION #769

Question 1743

$\int x\cos x\, dx = ?$

$x\sin x - \cos x + c$
$x\sin x - \cos x - c$✔️
$x\cos x - \sin x + c$
None

Correct Answer Logic:

Using integration by parts: $\int x\cos x\, dx = x\sin x - \int \sin x\, dx = x\sin x + \cos x + c$. Note: The paper marks option B ($x\sin x - \cos x - c$) but the standard result is $x\sin x + \cos x + c$.

Paper-II (Pharmacognosy and Pharmaceutics-I) QUESTION #2988

Question 1746

How many micrograms ($\mu\text{g}$) are in $0.5\text{ milligrams}$ ($mg$)?

$50\text{ }\mu\text{g}$
$500\text{ }\mu\text{g}$✔️
$5000\text{ }\mu\text{g}$
$0.0005\text{ }\mu\text{g}$

Correct Answer Logic:

$1\text{ mg} = 1000\text{ }\mu\text{g}$, so $0.5\text{ mg} = 500\text{ }\mu\text{g}$.

Disaster Management QUESTION #6553

Question 1747

What makes multi-hazard early warning systems more effective than single-hazard approaches?

They cost more✔️
They integrate multiple hazard monitoring into unified communication systems, reducing warning fatigue and improving resource efficiency
They're more complex
They require more staff

Correct Answer Logic:

Section 7.1 promotes Multi-Hazard Early Warning Systems (MHEWS) integrated into NCOP. While unified systems improve efficiency and reduce warning fatigue, the question asks about effectiveness - integration prevents gaps between hazards and ensures comprehensive coverage, making option 1 most accurate about why they're more effective.

Biology Zoology Botany QUESTION #10820

Question 1749

Most mammals have how many sets of teeth (dentitions) during their lifetime?

3
4
5
2✔️

Correct Answer Logic:

Most mammals are diphyodont — they develop two successive sets of teeth: deciduous (milk/baby) teeth and permanent (adult) teeth. This contrasts with most non-mammalian vertebrates, which are polyphyodont (continuous tooth replacement throughout life). Exceptions include elephants (six sets of molars), some marsupials, and cetaceans, which are monophyodont (one set).

Maths QUESTION #7941

Question 1750

Which of the following sets of fractions is arranged in descending order?

$\dfrac{3}{4}, \dfrac{7}{9}, \dfrac{6}{7}$
$\dfrac{7}{9}, \dfrac{3}{5}, \dfrac{6}{7}$
$\dfrac{7}{9}, \dfrac{6}{7}, \dfrac{3}{5}$
$\dfrac{6}{7}, \dfrac{7}{9}, \dfrac{3}{5}$✔️

Correct Answer Logic:

Convert each fraction to decimal to compare:

$\dfrac{6}{7} \approx 0.857$
$\dfrac{7}{9} \approx 0.778$
$\dfrac{3}{5} = 0.600$

Descending order: $\dfrac{6}{7} > \dfrac{7}{9} > \dfrac{3}{5}$, which matches option D.

Question 1751

Choose the correct word: 'They decided to ___ the old building.' (Note: 'Raise' means to lift up; 'Raze' means to completely destroy)

Electronics Engineering QUESTION #11699

Question 1752

An inductor is tested with an LCR meter at 1 kHz. The measured inductance is correct but Q-factor reads 0.8 instead of the expected 50. The most likely fault is:

Shorted turns in the winding✔️
An open-circuit winding
Core saturation from DC bias
Wrong test frequency selected

Correct Answer Logic:

A drastically low Q-factor while inductance appears near-nominal is characteristic of shorted turns. Shorted turns create a transformer-like secondary loop that dissipates energy, dramatically increasing equivalent series resistance (ESR) and reducing Q. An open winding would give an OL reading; core saturation affects inductance under DC bias.

The entire statement
Only so much as relates distinctly to the fact thereby discovered✔️

Only the part that amounts to a confession

Correct Answer Logic:

Article 40 allows proof of only so much of the information as relates distinctly to the fact thereby discovered, whether or not it amounts to a confession.

Law QUESTION #9500

Question 1755

A Court of first instance passes an ex parte decree against B. B applies to set it aside, but his application is dismissed. B then appeals against the ex parte decree itself. Is this appeal maintainable?

No; B cannot avail both remedies simultaneously
No; B's only remedy is the application to set aside the ex parte decree
No; B waived his appeal right by first applying to set aside the decree
Yes; where the application to set aside an ex parte decree is dismissed, B retains the right to appeal against the original ex parte decree; both remedies co-exist✔️

Correct Answer Logic:

Under Order IX Rule 13 and Order XLIII CPC, there is no bar on a defendant simultaneously or sequentially pursuing an application to set aside an ex parte decree and an appeal from that decree. These are independent remedies. Dismissal of the application does not extinguish the right of appeal.

Sociology QUESTION #1670

Question 1756

The theoretical concept of 'hegemonic masculinity,' which examines how a dominant form of masculinity is culturally exalted and reproduced within a hierarchy of masculinities to sustain patriarchal social arrangements, was most centrally developed to address which sociological problem?

Explaining how capitalist ideology maintains class hegemony through gender norms
Analyzing how gender inequality is reproduced through the privileging of certain forms of masculinity over others and over femininities
Studying the internal power dynamics and subordination relationships among competing configurations of masculinity✔️
Critiquing the functionalist assumption that gender roles are biologically determined and socially functional

Correct Answer Logic:

Hegemonic masculinity, developed primarily by R.W. Connell (building on Gramsci's concept of hegemony), describes the culturally dominant form of masculinity that legitimizes men's dominance over women and over subordinated masculinities. It is a relational concept focused on the structural reproduction of gender hierarchy through the valorization of particular masculine ideals.
