Education QUESTION #6913

According to classroom management research on large classes, which of the following is identified as an ADVANTAGE rather than a challenge of larger class sizes?

Easier individual attention and personalized feedback for each student
Higher-than-average homogeneity in student ability, which simplifies lesson planning
The availability of peer diversity enables peer-teaching, collaborative strategies, and natural professional development for teachers✔️
Better student-to-material ratios since resources are shared across more students

Correct Answer Logic:

While large classes present significant challenges, research identifies specific advantages: the diversity of the class creates a rich human resource for peer-teaching and collaborative learning; proficient students can support weaker peers; and teachers are continually challenged to innovate, resulting in organic professional development. These advantages can be leveraged through deliberate cooperative learning structures.

Physics QUESTION #7084

Question 2224

If velocity ($V$), acceleration ($A$), and force ($F$) are the fundamental units, find the dimensions of Young's modulus.

$V^{-2}A^{2}F^{-2}$
$V^{-2}A^{2}F^{2}$
$V^{-4}A^{-2}F$
$V^{-4}A^{2}F$✔️

Correct Answer Logic:

Young's Modulus $[Y] = [ML^{-1}T^{-2}]$.

Force $[F] = [MLT^{-2}] \implies M = F L^{-1} T^2$
Velocity $[V] = [LT^{-1}]$ and Acceleration $[A] = [LT^{-2}]$
Solving for $L$ and $T$: $T = V/A$ and $L = V^2/A$.
Substituting these into the formula for $Y$ yields $V^{-4}A^2F$.

Maths QUESTION #7651

Question 2225

If $x + \frac{1}{x} = 15$, then the value of $x^2 + \frac{1}{x^2}$ is:

$225$
$223$✔️
$17$
None of these

Correct Answer Logic:

To find $x^2 + \frac{1}{x^2}$, we square the given equation: $\left(x + \frac{1}{x}\right)^2 = 15^2$. Expanding: $x^2 + 2 \cdot x \cdot \frac{1}{x} + \frac{1}{x^2} = 225$. This simplifies to $x^2 + 2 + \frac{1}{x^2} = 225$. Therefore, $x^2 + \frac{1}{x^2} = 225 - 2 = 223$.

Physics QUESTION #7001

Question 2231

The graph best representing the variation of acceleration due to gravity $g$ with distance $d$ from Earth's centre (Earth's radius $= R$) shows which behaviour?

$g$ peaks sharply at $d = R$ with linear rise inside and $1/d^2$ fall outside
$g$ increases exponentially throughout with no peak
$g$ rises linearly from 0 to a peak at $d = R$ then falls as $1/d^2$ outside✔️
$g$ is constant inside and decreases outside

Correct Answer Logic:

The correct behaviour of $g$:

Inside the Earth ($d < R$): $g = \frac{GM}{R^3}d$ — linear increase from $g=0$ at centre to $g_{surface}$ at $d=R$.
Outside the Earth ($d > R$): $g = \frac{GM}{d^2}$ — decreases as $1/d^2$.

The graph shows a straight line from origin to $(R, g_{max})$, then a smooth $1/d^2$ curve decreasing afterward. This is a linear rise inside and inverse-square fall outside, meeting at a sharp peak at $d = R$.

Geography QUESTION #6316

Question 2232

The rank-size rule in urban geography suggests that the population of a city ranked n should be:

1/n of the largest city's population✔️
Equal to the largest city divided by n squared
Determined by economic base multiplier
Independent of other cities' populations

Correct Answer Logic:

The rank-size rule states: Pn = P1/n where Pn is the population of city ranked n and P1 is the largest city. In a country following this rule, the 2nd city has half the largest city's population, the 3rd city has one-third, etc.

Correct Answer Logic:

Goodwill is an intangible asset — it represents non-physical value such as brand reputation, customer relationships, and business synergies. It appears on the balance sheet under non-current intangible assets and arises when a business is purchased for more than the fair value of its net identifiable assets.

Mathematics QUESTION #7477

Question 2237

Let $\vec{a} = \hat{i} - \hat{j}$, $\vec{b} = \hat{i} + \hat{j} + \hat{k}$ and $\vec{c}$ be a vector such that $\vec{a} \times \vec{c} + \vec{b} = \vec{0}$ and $\vec{a} \cdot \vec{c} = 4$, then $|\vec{c}|^2$ is equal to:

$\frac{19}{2}$✔️
9
8
$\frac{17}{2}$

Correct Answer Logic:

From $\vec{a} \times \vec{c} + \vec{b} = \vec{0}$, we get $\vec{a} \times \vec{c} = -\vec{b}$. Taking dot product with $\vec{a}$: $\vec{a} \cdot (\vec{a} \times \vec{c}) = -\vec{a} \cdot \vec{b}$. Since $\vec{a} \cdot (\vec{a} \times \vec{c}) = 0$, we have $\vec{a} \cdot \vec{b} = 0$, which checks: $(1)(-1)+(-1)(1)+(0)(1) = 0$. Nope: $\vec{a} = \hat{i}-\hat{j}$ (only 2D) and $\vec{b} = \hat{i}+\hat{j}+\hat{k}$, so $\vec{a} \cdot \vec{b} = 1-1 = 0$. Good. Taking magnitude: $|\vec{a} \times \vec{c}| = |\vec{b}| = \sqrt{3}$. Also $|\vec{a} \times \vec{c}|^2 = |\vec{a}|^2|\vec{c}|^2 - (\vec{a} \cdot \vec{c})^2$, so $3 = 2|\vec{c}|^2 - 16$, giving $|\vec{c}|^2 = \frac{19}{2}$.

Question 2239

If the surface charge density of an infinite sheet increases by $25\%$, the electric field intensity:

Increases by $25\%$✔️
Increases by $50\%$
Decreases by $25\%$
Remains the same

Correct Answer Logic:

Electric field due to an infinite sheet: $E = \dfrac{\sigma}{2\varepsilon_0}$. Since $E \propto \sigma$ (direct proportion), if $\sigma$ increases by $25\%$, then $E$ also increases by $25\%$.

Chemistry QUESTION #4380

Question 2240

If $\%$ yield is $80\%$ and actual yield is $20\ g$, what will be the theoretical yield?

20 g
25 g✔️
30 g
40 g

Correct Answer Logic:

$\% yield = \dfrac{actual\ yield}{theoretical\ yield} \times 100$. Rearranging: $theoretical\ yield = \dfrac{actual\ yield}{\% yield} \times 100 = \dfrac{20}{80} \times 100 = 25\ g$.
