Physics QUESTION #1165

At constant pressure and volume, the exact relation between $C_p$ and $C_v$ is:

C_p > C_v
$C_p / C_v > 1$
$C_p - C_v = R$
All of these✔️

Correct Answer Logic:

All three relations are simultaneously true for an ideal gas: (A) $C_p > C_v$ because at constant pressure extra heat is needed to do work against expansion. (B) $C_p/C_v = \gamma > 1$. (C) The Mayer relation: $C_p - C_v = R$ (per mole). So all of these are correct.

Chemistry QUESTION #5582

Question 3483

In a reaction sequence, sodium phenoxide reacts with $CO_2$ under pressure at 125°C (Kolbe–Schmitt reaction) to give B, which on acetylation with $Ac_2O$ gives C. What is the major product C?

Methyl salicylate (OH and $COOCH_3$ on ring)
Ortho-acetoxybenzoic acid ($OCOCH_3$ and $COOH$ ortho)✔️
Para-acetoxybenzoic acid ($OCOCH_3$ and $COOH$ para)
A compound with keto groups

Correct Answer Logic:

Kolbe–Schmitt reaction: Sodium phenoxide + $CO_2$ (125°C, 5 atm) → Sodium salicylate (2-hydroxybenzoate), acidified to give salicylic acid (B = 2-hydroxybenzoic acid). Acetylation of salicylic acid with $Ac_2O$ preferentially acetylates the –OH group → product C = 2-(acetyloxy)benzoic acid = aspirin (ortho-acetoxybenzoic acid).

Physics QUESTION #7340

Question 3488

The horizontal range and maximum height of a projectile are equal. The angle of projection is:

$\theta = \tan^{-1}(2)$
$\theta = 45°$
$\theta = \tan^{-1}\!\left(\dfrac{1}{4}\right)$
$\theta = \tan^{-1}(4)$✔️

Correct Answer Logic:

$R = H \Rightarrow \dfrac{u^2\sin2\theta}{g} = \dfrac{u^2\sin^2\theta}{2g}$

$4\sin\theta\cos\theta = \sin^2\theta \Rightarrow 4\cos\theta = \sin\theta \Rightarrow \tan\theta = 4$

$\theta = \mathbf{\tan^{-1}(4)}$

Under what circumstances may an auditor deviate from professional audit standards?

Standards are intended for discretionary application
Deviation is extremely rare and would demand substantial justification✔️
Deviation depends on the scope of authority granted by the audit charter
The specific nature of the client environment allows for auditor flexibility

Correct Answer Logic:

Math (Module-1) QUESTION #5479

Question 3492

An isosceles right triangle has a hypotenuse of length $58$ inches. What is the perimeter, in inches, of this triangle?

$29\sqrt{2}$
$58\sqrt{2}$
$58 + 58\sqrt{2}$✔️
$58 + 116\sqrt{2}$

Correct Answer Logic:

Leg length $s = \frac{58}{\sqrt{2}} = 29\sqrt{2}$. Perimeter $= 2s + 58 = 2(29\sqrt{2}) + 58 = 58\sqrt{2} + 58$.

Accounting & Finance QUESTION #6052

Question 3493

Which one of the following qualifies as a capital expenditure?

Paying for renovations that upgrade and improve a building✔️
Paying carriage-outward charges related to delivering sold goods
Paying legal fees to recover outstanding amounts from customers

Correct Answer Logic:

Capital expenditure is spending that improves, extends the life of, or adds value to a long-term asset. Renovating and upgrading a building increases its value and useful life — this is capital expenditure. The other options are all revenue expenditures: carriage outwards, legal recovery fees, and wage bonuses are period costs that appear on the income statement and do not create lasting assets.
