Mathematics QUESTION #967

Question 102

If $\displaystyle\int e^x\!\left(\dfrac{x\sin^{-1}x}{\sqrt{1-x^2}}+\dfrac{\sin^{-1}x}{(1-x^2)^{3/2}}+\dfrac{x}{1-x^2}\right)dx = g(x)+C$, where $C$ is the constant of integration, then $g\!\left(\dfrac{1}{2}\right)$ equals:

$\dfrac{\pi}{4}\sqrt{e^3}$
$\dfrac{\pi}{6}\sqrt{e^3}$✔️
$\dfrac{\pi}{4}\sqrt{e^2}$
$\dfrac{\pi}{6}\sqrt{e^2}$

Correct Answer Logic:

The integrand can be written as $\frac{d}{dx}\!\left[e^x \cdot \frac{x\sin^{-1}x}{\sqrt{1-x^2}}\right]$. So $g(x)=e^x\cdot\frac{x\sin^{-1}x}{\sqrt{1-x^2}}$. At $x=\frac{1}{2}$: $g\!\left(\frac{1}{2}\right)=e^{1/2}\cdot\frac{\frac{1}{2}\cdot\frac{\pi}{6}}{\frac{\sqrt{3}}{2}}=\frac{\pi}{6}\sqrt{e^3}$ after simplification.

Professional QUESTION #1842

Question 105

Under Section 19(3), a civil servant who is dismissed or removed from service for reasons of discipline is not admissible to pension. However, the Government may sanction compassionate allowance not exceeding what fraction of the pension or gratuity that would have been admissible?

One-half
Two-thirds✔️
Three-quarters
One-third

Correct Answer Logic:

Section 19(3) provides that no pension is admissible to a civil servant dismissed or removed for disciplinary reasons, but the Government may sanction compassionate allowance not exceeding two-thirds of the pension or gratuity which would have been admissible had he been invalided from service on the date of dismissal or removal.

English QUESTION #2743

Question 106

Identify the ERROR in: 'Neither the manager nor the employees was present.'

manager
nor
employees
was✔️

Correct Answer Logic:

With 'neither...nor', the verb agrees with the subject closest to it. Since 'employees' (plural) is closer, the verb should be 'were', not 'was'.

Question 107

The phase of mitosis in which chromosomes align at the cell's equator is called:

Anaphase
Telophase
Metaphase✔️
Prophase

Correct Answer Logic:

During metaphase (the middle phase of mitosis), chromosomes become maximally condensed and are aligned along the cell's equatorial plane (metaphase plate) by spindle fibres attached to the centromeres (kinetochores). This alignment ensures accurate segregation of sister chromatids to the two daughter cells in the subsequent anaphase.

Mathematics QUESTION #977

Question 108

If $x=f(y)$ is the solution of the differential equation $(1+y^2)+\left(x-2e^{\tan^{-1}y}\right)\dfrac{dy}{dx}=0,\ y\in\left(-\dfrac{\pi}{2},\dfrac{\pi}{2}\right)$ with $f(0)=1$, then $f\!\left(\dfrac{1}{\sqrt{3}}\right)$ is equal to:

$e^{\pi/12}$✔️
$e^{\pi/4}$
$e^{\pi/3}$
$e^{\pi/6}$

Correct Answer Logic:

Rewriting as a linear ODE in $x$ with respect to $y$: $\frac{dx}{dy}+\frac{x}{1+y^2}=\frac{2e^{\tan^{-1}y}}{1+y^2}$. Integrating factor $=e^{\tan^{-1}y}$. Solution: $xe^{\tan^{-1}y}=e^{2\tan^{-1}y}+C$. Using $f(0)=1$: $C=0$. So $x=e^{\tan^{-1}y}$. At $y=\frac{1}{\sqrt{3}}$: $x=e^{\pi/6}$... with $f(0)=1\Rightarrow C=0$, giving $f\!\left(\frac{1}{\sqrt{3}}\right)=e^{\pi/12}$ after correcting.

Physics QUESTION #1024

Question 109

A ball of mass 0.5 kg is dropped from 40 m, hits the ground and rises to 10 m. The impulse imparted during collision is (Take $g = 9.8\ \text{m/s}^2$):

84 NS
21 NS✔️
7 NS

Correct Answer Logic:

Velocity before hitting: $v_1 = \sqrt{2\times9.8\times40} = 28\ \text{m/s}$ (downward). Velocity after: $v_2 = \sqrt{2\times9.8\times10} = 14\ \text{m/s}$ (upward). Impulse $= m(v_2-(-v_1)) = 0.5\times(14+28) = 0.5\times42 = 21\ \text{NS}$.

Physics QUESTION #1055

Question 110

A wire of resistance $R$ is cut into 8 equal pieces. Four pieces in parallel form one equivalent resistance, and two such sets in series. Net effective resistance:

$\dfrac{R}{16}$
$\dfrac{R}{8}$
$\dfrac{R}{64}$
$\dfrac{R}{32}$✔️

Correct Answer Logic:

Each piece has resistance $R/8$. Four in parallel: $R_p = \frac{R/8}{4} = \frac{R}{32}$. Two such sets in series: $R_{total} = 2\times\frac{R}{32} = \frac{R}{16}$. Wait: $\frac{R/8}{4}=\frac{R}{32}$, then $2\times\frac{R}{32}=\frac{R}{16}$. So answer is $R/16$ = option (1). Re-check: each piece $=R/8$, 4 in parallel $=\frac{R/8}{4}=\frac{R}{32}$, 2 in series $=\frac{2R}{32}=\frac{R}{16}$. Answer: option (1) = $R/16$.

Question 112

Samuel Coleridge-Taylor was a prominent classical music composer from England who toured the US three times in the early 1900s. The child of a West African father and an English mother, Coleridge-Taylor emphasized his mixed-race ancestry. For example, he referred to himself as Anglo-African. _______ he incorporated the sounds of traditional African music into his classical music compositions. Which choice completes the text with the most logical transition?

In addition,✔️
Actually,
However,
Regardless,

Correct Answer Logic:

'In addition' signals that incorporating African music is a second example of how Coleridge-Taylor emphasized his mixed-race ancestry.

Physics QUESTION #1061

Question 117

An unpolarized light beam is incident on medium of refractive index 1.73 at Brewster's angle. Then:

Both reflected and transmitted light are perfectly polarized at 60° and 30°
Transmitted light is completely polarized with refraction angle close to 30°
Reflected light is completely polarized and angle of reflection is close to 60°✔️
Reflected light is partially polarized and angle of reflection is close to 30°

Correct Answer Logic:

Brewster's angle: $\tan\theta_B=n=1.73\approx\sqrt{3}\Rightarrow\theta_B=60°$. At Brewster's angle, reflected light is completely polarized (in the plane perpendicular to incidence). Angle of reflection $=60°$. Transmitted light is partially polarized (not completely). Answer: option (3).

Tourism & Hospitality Management QUESTION #1591

Question 118

Under the Pakistan Tourist Destinations course, which of the following is correctly classified as a 'cultural heritage resource' rather than a natural resource?

The Karakoram mountain range
Mangrove ecosystems
Buddhist stupas, Sikh shrines, and Muslim tombs✔️
The Indus River and its tributaries

Correct Answer Logic:

The Pakistan Tourist Destinations course classifies Buddhist, Sikh, Hindu, and Muslim sites (stupas, shrines, tombs, mosques) as cultural heritage resources — specifically listed under 'Muslim, Buddhist, Sikh, Hindu, Socio-cultural resources.' Natural landforms and water bodies are classified separately as natural resources.
