Question 2

A particle moves along a straight line with constant acceleration, changing speed from $10\text{ m/s}$ to $20\text{ m/s}$ while covering $135\text{ m}$. The time taken is:

12 s
9 s✔️
10 s
1.8 s

Correct Answer Logic:

Using $v^2 - u^2 = 2as$: $(20)^2 - (10)^2 = 2a(135) \Rightarrow 300 = 270a \Rightarrow a = \dfrac{10}{9}\text{ m/s}^2$

Using $v = u + at$: $20 = 10 + \dfrac{10}{9}t \Rightarrow t = \mathbf{9\text{ s}}$

Question 4

In a cantilever beam, the main tension reinforcement should be placed:

Question 5

$3^{72/100}$ written as a fraction is:

3.72
37.2
0.372✔️
372

Correct Answer Logic:

$3^{72/100} = 3.72$ — wait, this is a notation question. $3\tfrac{72}{100} = 3 + 0.72 = 3.72$ as a decimal, or $\dfrac{372}{100} = 0.372$ when simplified... The answer key gives C (0.372). Note: $\dfrac{372}{100} = 3.72$ not 0.372. Answer key may contain a typo; the mixed number $3\tfrac{72}{100} = 3.72$.

Question 7

For a state of plane stress $(\sigma_x, \sigma_y, \tau_{xy})$, the maximum in-plane shear stress is:

$\tau_{max} = \sqrt{\left(\frac{\sigma_x - \sigma_y}{2}\right)^2 + \tau_{xy}^2}$✔️
$\tau_{max} = \frac{\sigma_x + \sigma_y}{2}$
$\tau_{max} = \sigma_x - \sigma_y$
$\tau_{max} = \tau_{xy}$

Correct Answer Logic:

The maximum in-plane shear stress equals the radius of Mohr's circle: $\tau_{max}=\sqrt{\left(\frac{\sigma_x-\sigma_y}{2}\right)^2+\tau_{xy}^2}$.

Mathematics QUESTION #1320

Question 12

If two vectors $\vec{a}$ and $\vec{b}$ satisfy $\vec{a}\times\vec{b}=\vec{0}$ and $\vec{a}\neq\vec{0}$, $\vec{b}\neq\vec{0}$, then:

They are perpendicular
They are parallel✔️
Their magnitudes are equal
Their dot product is zero

Correct Answer Logic:

The cross product $\vec{a}\times\vec{b}=|\vec{a}||\vec{b}|\sin\theta\,\hat{n}$. If $\vec{a}\times\vec{b}=\vec{0}$ and neither vector is zero, then $\sin\theta=0\Rightarrow\theta=0$ or $\pi$, meaning the vectors are parallel (or anti-parallel).

Sociology QUESTION #1668

Question 13

C. Wright Mills argued in his 1956 work that democratic governance in the United States was effectively superseded by the coordinated dominance of a small, interconnected elite drawn from corporate, military, and political institutions. The concept he developed to describe this concentration of power is:

The Iron Law of Oligarchy
The Power Elite✔️
The Ruling Class
The Military-Industrial Complex

Correct Answer Logic:

In 'The Power Elite' (1956), C. Wright Mills argued that real power in the United States is held by a small group of men who occupy the command posts of the major institutional hierarchies — large corporations, the military, and the executive branch of government — whose interests are intertwined and who make the most consequential decisions affecting society.

Physics QUESTION #7066

Question 15

A cube of maximum possible volume is cut from a solid sphere of mass $M$ and radius $R$. Find the moment of inertia of this cube about an axis that passes through its center and is perpendicular to one of its faces.

$\frac{MR^2}{32\sqrt{2}\pi}$
$\frac{MR^2}{16\sqrt{2}\pi}$
$\frac{4 MR^2}{9\sqrt{3}\pi}$✔️
$\frac{4 MR^2}{3\sqrt{3}\pi}$

Correct Answer Logic:

1. Find Cube Side ($a$): The body diagonal of the cube equals the diameter of the sphere. $\sqrt{3}a = 2R \implies a = \frac{2R}{\sqrt{3}}$.

2. Find Cube Mass ($m$): Density $\rho = \frac{M}{\frac{4}{3}\pi R^3}$. Mass of cube $m = \rho \times a^3 = \left(\frac{3M}{4\pi R^3}\right) \times \left(\frac{8R^3}{3\sqrt{3}}\right) = \frac{2M}{\pi \sqrt{3}}$.

3. Moment of Inertia ($I$): For a cube about the center-face axis, $I = \frac{ma^2}{6}$.
$I = \frac{1}{6} \left( \frac{2M}{\pi \sqrt{3}} \right) \left( \frac{4R^2}{3} \right) = \frac{8MR^2}{18\pi \sqrt{3}} = \frac{4MR^2}{9\sqrt{3}\pi}$.

Education QUESTION #6911

Question 18

A student who is aggressive frequently misinterprets neutral social cues as hostile — for example, reading an accidental shoulder bump as an intentional act of aggression. This pattern reflects which documented characteristic of aggressive students?

A performance deficit in social skills due to lack of practice
Deficits in social information processing, leading to systematic misattribution of hostile intent✔️
A conduct disorder that can only be addressed through psychiatric intervention
Deliberate manipulation of social situations for personal gain

Correct Answer Logic:

Research on aggression in school contexts consistently identifies social information processing deficits as a core characteristic of chronically aggressive students. These students are more likely to misread neutral or ambiguous social cues as threatening, especially under stress, which triggers aggressive responses that peers and teachers experience as disproportionate or unprovoked.

Tourism & Hospitality Management QUESTION #1621

Question 20

The Tourism Management course covers 'managing urban tourism.' Which of the following is identified as a key challenge specific to urban tourism management?

Lack of accommodation in rural areas
Balancing the needs of resident populations with the demands of tourists, managing heritage sites in urban contexts, and addressing overcrowding and infrastructure strain✔️
The absence of natural attractions in cities
The high cost of adventure sports in urban environments

Correct Answer Logic:

Module 3 of the Tourism Management course — 'Managing Tourism in Its Environment' — covers urban tourism and identifies key challenges including: integrating tourism within existing urban infrastructure, managing heritage sites, balancing resident quality of life against tourist demand, and addressing overcrowding — issues that differ fundamentally from rural or natural-area tourism management.
