Question 3703

Which tribe of Quraish, Hazrat Umar, belonged to?

Banu Hasham
Banu Umayyah
Banu Addi✔️
None of these

Initially, he was a fierce opponent of Islam but converted in 616 CE (6th year of prophethood). His conversion strengthened Islam so much that Muslims began praying openly at the Kaaba. He became the second Caliph and ruled from 634-644 CE, expanding the Islamic empire significantly.

Accounting & Finance QUESTION #6135

Question 3704

A trial balance had a suspense account with a credit balance of $1,720. Errors found: (1) Purchases returns balance of $440 omitted from trial balance; (2) Bank overdraft balance understated by $90. What is the updated credit balance of the suspense account?

$1,190
$1,370
$2,070✔️
$2,250

Correct Answer Logic:

Option C ($2,070) is correct.

Error 1: Purchases returns (credit balance) omitted → credit total understated → Credit suspense $440.

Error 2: Bank overdraft (credit balance) understated → Credit suspense $90.

Updated balance = $1,720 + $440 − $90 = $2,070

Accounting & Finance QUESTION #6148

Question 3705

Financial data: Profit from operations $59,800; Finance costs $12,000; Profit for year $47,800; Ordinary share capital $700,000; Retained earnings $72,500; 10% Debentures $120,000. What was the ROCE?

5.36%
6.19%
6.70%✔️
7.74%

Correct Answer Logic:

Option C (6.70%) is correct.

Capital Employed = ($700,000 + $72,500) + $120,000 = $892,500

ROCE = $59,800 ÷ $892,500 × 100 = 6.70%

Geography QUESTION #1232

Question 3707

Under which wind system does the direction of winds change daily?

Trade winds
Monsoon winds
Land and sea breeze✔️
None of these

Correct Answer Logic:

Land and sea breezes change direction daily due to differential heating and cooling of land and water. During the day, land heats faster than sea, so cool air blows from sea to land (sea breeze). At night, land cools faster, so air blows from land to sea (land breeze). Trade winds are steady and persistent; monsoon winds change seasonally (not daily).

Chemistry QUESTION #7111

Question 3708

For the redox reaction $Zn(s) + Cu^{2+}(aq) \rightleftharpoons Zn^{2+}(aq) + Cu(s)$ at $300\text{ K}$, given $E^{0}_{cell} = 2\text{ V}$, $R = 8\text{ J K}^{-1}\text{ mol}^{-1}$, and $F = 96000\text{ C mol}^{-1}$, calculate the approximate equilibrium constant ($K$).

$e^{-80}$
$e^{-160}$
$e^{320}$
$e^{160}$✔️

Correct Answer Logic:

The relationship is $\Delta G^{0} = -nFE^{0} = -RT \ln K$. Here $n=2$.
$-2 \times 96000 \times 2 = -8 \times 300 \times \ln K$
$-384000 = -2400 \ln K$
$\ln K = \frac{384000}{2400} = 160$. Therefore, $K = e^{160}$.

Geography QUESTION #6317

Question 3710

Christaller's Central Place Theory assumes a hexagonal market area pattern because:

Hexagons are the most aesthetically pleasing shape
Hexagons minimize distance to central place while eliminating overlap and gaps✔️
Hexagons represent medieval European town planning traditions
Hexagons maximize competition between central places

Correct Answer Logic:

Hexagons are the most efficient shape filling 2D space without gaps or overlaps while minimizing average distance from periphery to center. Circles leave gaps; squares/triangles create unequal distances. Hexagons optimize both complete coverage and accessibility.

Physics QUESTION #1029

Question 3713

In an oscillating spring-mass system, sand leaks slowly out of the box vertically as it oscillates. Which schematic correctly shows changes in average frequency $\omega(t)$ and average amplitude $A(t)$ with time?

Frequency increases (curve up), amplitude increases (curve up)✔️
Frequency decreases (curve down), amplitude decreases (curve down)
Frequency increases (curve up), amplitude stays constant (flat)
Frequency increases (curve up), amplitude decreases (curve down)

Correct Answer Logic:

As sand leaks out, mass decreases. $\omega = \sqrt{k/m}$: as $m$ decreases, $\omega$ increases. Amplitude: since sand leaks vertically (no horizontal impulse), energy is not added but mass decreases — the amplitude increases as $A = v_{max}/\omega$ and the system conserves momentum. Frequency increases and amplitude increases gradually.

Dairy Food Science and Technology QUESTION #5933

Question 3715

The inhibitory system in raw milk providing natural antimicrobial protection is:

The complement system
The lactoperoxidase-thiocyanate-$\text{H}_2\text{O}_2$ (LP) system: $\text{H}_2\text{O}_2 + \text{SCN}^- \xrightarrow{\text{LPO}} \text{OSCN}^-$✔️
The lactoferrin-iron sequestration system
The lysozyme-murein lysis system

Correct Answer Logic:

The LP system: $\text{H}_2\text{O}_2$ (substrate) $+$ $\text{SCN}^-$ $+$ lactoperoxidase (enzyme) $\rightarrow$ hypothiocyanite ($\text{OSCN}^-$) that oxidizes microbial sulfhydryl groups, inhibiting bacterial growth. This system provides $\approx 2\text{–}3$ hours of protection in raw milk at ambient temperature.

Civil Procedure QUESTION #3687

Question 3720

In a diversity action in federal court in State A, the court must decide which statute of limitations to apply. State A has a 2-year limit, while State B (where the accident occurred) has a 4-year limit. There is no Federal Rule of Civil Procedure governing the limitation period. Under the Erie doctrine, what should the court do?

Apply the federal common law 3-year limitation.
Apply State A's 2-year limit, because statutes of limitations are substantive for Erie purposes.✔️
Apply State B's 4-year limit, because the accident happened there.
Apply whichever limit is more favorable to the plaintiff to ensure access to justice.

Correct Answer Logic:

Under Guaranty Trust Co. v. York, statutes of limitations are outcome-determinative and therefore substantive for Erie purposes. A federal court sitting in diversity must apply the statute of limitations of the state in which it sits.
