Chemistry QUESTION #7497

Question 1842

In which of the following processes is the change in oxidation state equal to five?

$\text{C}_2\text{O}_4^{2-} \to 2\text{CO}_2$
$\text{MnO}_4^- \to \text{Mn}^{2+}$✔️
$\text{Cr}_2\text{O}_7^{2-} \to 2\text{Cr}^{3+}$
$\text{CrO}_4^{2-} \to \text{Cr}^{3+}$

Correct Answer Logic:

Calculate the change in oxidation state for each:

(A) C in C$_2$O$_4^{2-}$: $+3$; C in CO$_2$: $+4$. Change $= +1$ per C atom (2 C, so total = 2, but per atom = 1).
(B) Mn in MnO$_4^-$: $+7$; Mn in Mn$^{2+}$: $+2$. Change $= 7 - 2 = \mathbf{5}$ ✓
(C) Cr in Cr$_2$O$_7^{2-}$: $+6$; Cr in Cr$^{3+}$: $+3$. Change $= 3$ per Cr atom.
(D) Cr in CrO$_4^{2-}$: $+6$; Cr in Cr$^{3+}$: $+3$. Change $= 3$.

The change of 5 occurs in the conversion $\text{MnO}_4^- \to \text{Mn}^{2+}$.

Accounting & Finance QUESTION #1211

Question 1843

In a sales mix decision, the product with the highest contribution margin per unit should be:

Sold exclusively, regardless of customer demand.
Prioritized when resources are constrained.✔️
Avoided to reduce risk.
Discounted to maximize revenue.

Correct Answer Logic:

When resources (such as machine hours or materials) are constrained, products should be ranked by contribution margin per unit of the limiting factor (not just per unit). The product yielding the highest contribution margin per scarce resource should be prioritized to maximize total contribution and profit. Selling exclusively ignores demand and other constraints.

Mathematics QUESTION #7447

Question 1844

If the 2nd, 5th and 9th terms of a non-constant A.P. are in G.P., then the common ratio of this G.P. is:

$\frac{4}{3}$✔️
1
$\frac{7}{4}$
$\frac{8}{5}$

Correct Answer Logic:

Let the A.P. be $a, a+d, a+2d, \ldots$ The 2nd term is $a+d$, 5th term is $a+4d$, and 9th term is $a+8d$. For these to be in G.P.: $(a+4d)^2 = (a+d)(a+8d)$. Expanding: $a^2 + 8ad + 16d^2 = a^2 + 9ad + 8d^2$, which simplifies to $8d^2 = ad$. Since the A.P. is non-constant, $d \neq 0$, so $a = 8d$. The three terms become $9d, 12d, 16d$. Common ratio = $\frac{12d}{9d} = \frac{4}{3}$.

Question 1847

In open channel flow the pressure condition is __________, whereas in pipe flow the pressure is __________:

Atmospheric; higher than atmospheric✔️

Question 1850

'Priming' in a boiler refers to the phenomenon where:

The boiler is started for the first time
Water droplets are carried away with the steam into the pipes✔️
The fuel fails to ignite
The boiler pressure drops suddenly

Correct Answer Logic:

Priming can cause water hammer and damage to engines/turbines; it's often caused by high water levels or impurities.

Mathematics QUESTION #4146

Question 1853

For the ODE $y'' - 3y' + 2y = e^x$, what is the form of particular solution $y_p$ using undetermined coefficients?

$Ae^x$
$Axe^x$✔️
$Ax^2e^x$
$A\cos(x) + B\sin(x)$

Correct Answer Logic:

Characteristic equation: $r^2 - 3r + 2 = 0$ gives $r = 1, 2$. Since $e^x$ corresponds to $r=1$ (simple root), multiply by $x$: $y_p = Axe^x$.

Biomedical Sciences QUESTION #3806

Question 1854

A pharyngeal infection spreads to the eustachian tube. Which adjacent anatomical structure would the infection most likely affect next?

Auditory nerve
Inner ear
Middle ear✔️
External auditory canal

Correct Answer Logic:

The eustachian tube connects the nasopharynx to the middle ear cavity. An infection spreading along this route would most likely involve the middle ear, causing otitis media.

Accounting & Finance QUESTION #6051

Question 1855

A business records a credit sale of Rs. 350 (no cash involved) using accrual accounting. How will this transaction be reflected in the financial statements?

Rs. 350 would appear on the balance sheet as a sale
Rs. 350 would appear on the income statement as a sale✔️
Rs. 350 would appear on the statement of cash flows as a cash outflow
The transaction would not be reported since no cash was exchanged

Correct Answer Logic:

Under accrual accounting, revenue is recognized when it is earned, not when cash is received. A credit sale of Rs. 350 means the business has earned the revenue, so it is recorded in the income statement as sales revenue. The receivable (Rs. 350) is recorded on the balance sheet as an asset, but the sale itself appears on the income statement. Cash-basis accounting would delay recognition until cash is received, but accrual accounting does not.

Civil Engineering QUESTION #6606

Question 1856

A wide-flange section is used as a beam-column. If the axial load ratio $P_u / (\phi P_n)$ is greater than 0.2, which interaction equation form is required by AISC?

$\frac{P_u}{\phi P_n} + \frac{M_u}{\phi M_n} \le 1.0$
$\frac{P_u}{2\phi P_n} + \frac{M_u}{\phi M_n} \le 1.0$
$\frac{P_u}{\phi P_n} + \frac{8}{9}(\frac{M_{ux}}{\phi_b M_{nx}} + \frac{M_{uy}}{\phi_b M_{ny}}) \le 1.0$✔️
$\frac{P_u}{\phi P_n} + \frac{1}{2}(\frac{M_u}{\phi M_n}) \le 1.0$

Correct Answer Logic:

For $P_u / \phi P_n \ge 0.2$, the AISC interaction formula weights the axial component fully and reduces the moment component slightly (multiplied by 8/9). For ratios < 0.2, the axial component is halved.

Law QUESTION #9524

Question 1859

A decree is passed jointly against B, C and D for Rs. 900,000, each being jointly and severally liable. B pays the entire Rs. 900,000 to the decree-holder A and fully satisfies the decree. B then seeks to recover proportionate contribution from C and D. Can B do so through the same execution proceedings?

No; once B pays, all rights are extinguished including B's right of contribution
Yes; B can apply for execution against C and D for contribution in the same proceedings
Yes; B is deemed a decree-holder to the extent of the other shares
No; B's right to recover contribution from C and D is by way of a separate suit; the decree between A and the judgment-debtors cannot be used by one judgment-debtor against another in execution✔️

Correct Answer Logic:

The execution proceedings under a decree are for the benefit of the decree-holder against judgment-debtors. One judgment-debtor who pays the full amount satisfies the decree, discharging the others. B's right of contribution from C and D arises from separate equitable or legal principles and must be pursued by a separate suit, not through the original execution proceedings.

Question 1860

If $a:b = 2:3$ and $b:c = 4:5$, what is $a:c$?

$8:15$✔️
$2:5$
$6:20$
Cannot determine

Correct Answer Logic:

$a:b = 2:3$ and $b:c = 4:5$. Make $b$ equal: $a:b = 8:12$ and $b:c = 12:15$. So $a:c = 8:15$
