Question 10084

For geometric similitude between model and prototype, if the linear scale ratio is $L_r = L_m/L_p$, the area ratio is:

$A_r = L_r$
$A_r = L_r^3$
$A_r = L_r^2$✔️
$A_r = L_r^{1/2}$

Correct Answer Logic:

For geometric similitude: all corresponding lengths scale by $L_r=L_m/L_p$. Areas scale as $A_r=L_r^2$, volumes scale as $V_r=L_r^3$.

Physics QUESTION #7092

Question 10086

A body is projected at $10\text{ ms}^{-1}$ at $60^{\circ}$ to the horizontal. Calculate the radius of curvature at $t=1\text{ s}$ ($g=10\text{ ms}^{-2}$).

10.3 m
2.8 m✔️
2.5 m
5.1 m

Correct Answer Logic:

Radius of curvature $R = \frac{v^2}{a_{\perp}}$.

At $t=1$: $v_x = 10 \cos 60^{\circ} = 5$; $v_y = 10 \sin 60^{\circ} - 10(1) = 5\sqrt{3} - 10 \approx -1.34$.
Total $v = \sqrt{5^2 + (-1.34)^2} \approx 5.18$.
$a_{\perp} = g \cos \theta$ where $\theta$ is the angle of the velocity vector. After calculation, $R \approx 2.8\text{ m}$.

Question 10088

In Mohr's circle for plane stress, the principal stresses $\sigma_1$ and $\sigma_2$ occur at points where:

The circle has maximum radius
The circle intersects the $\sigma$-axis (shear stress $\tau = 0$)✔️
The shear stress is maximum
The normal stress equals the average stress

Correct Answer Logic:

Principal stresses are defined as the normal stresses acting on planes where shear stress is zero. On Mohr's circle, these correspond to the two points where the circle intersects the horizontal $\sigma$-axis (i.e., $\tau = 0$).

Constitutional Law QUESTION #5822

Question 10091

Congress passes a law providing that 'no federal court shall have jurisdiction to hear any case involving the constitutionality of the Selective Service Act.' Is this law valid?

Yes, because Article III gives Congress power to make 'exceptions and regulations' to the Supreme Court's appellate jurisdiction.✔️
Yes, because military matters are 'political questions' beyond judicial review.
No, because Congress cannot strip the Supreme Court of all jurisdiction over a federal constitutional issue.
No, because it violates the Separation of Powers by dictating the outcome of cases.

Correct Answer Logic:

Under Article III, Section 2, Congress has the power to regulate and limit the appellate jurisdiction of the Supreme Court and to define the jurisdiction of inferior federal courts. While there are limits (it can't destroy the 'essential role' of the court), the MBE generally recognizes this broad 'Exceptions Clause' power.

Question 10092

Simplify: $\sqrt{225} + \sqrt{144} - \sqrt{81}$

12
15✔️
18
21

Correct Answer Logic:

$\sqrt{225} = 15$, $\sqrt{144} = 12$, $\sqrt{81} = 9$. So $15 + 12 - 9 = 18$. Answer is 18, which is option index 2.

Ability / HR / Governance / Special Education QUESTION #5648

Question 10094

The Regular Supplementary Grant differs fundamentally from the Technical Supplementary Grant in one critical way. Which statement CORRECTLY captures this distinction?

Regular Supplementary Grant requires Parliamentary presentation while Technical Supplementary Grant does not
Regular Supplementary Grant involves an upward change (additionality) in the sanctioned budget grant while Technical Supplementary Grant merely transfers funds between Grants/Demands without implying additionality✔️
Technical Supplementary Grant can only be used for Development Expenditure while Regular Supplementary Grant covers Current Expenditure
Regular Supplementary Grant is sanctioned by the Finance Division while Technical Supplementary Grant is sanctioned by the PAO

Correct Answer Logic:

The Technical Supplementary Grant does not imply any additionality to the sanctioned budget grant (it is a transfer from one Grant/Demand to another due to savings). The Regular Supplementary Grant involves an upward change in the sanctioned budget grant (actual additionality). Both must be presented to Parliament for ex-post authorization.

Administration QUESTION #9544

Question 10097

Maslow's Hierarchy of Needs is often misapplied in organizations. Which of the following scenarios correctly identifies a managerial error arising from misapplication of the hierarchy?

Offering performance bonuses to a newly recruited employee who lacks job security✔️
Providing a spacious office to a senior official who already has high social standing in the organization
Enrolling a motivated high-performer in a specialized professional development course to address growth needs
Forming cross-departmental committees to build team cohesion among mid-level managers

Correct Answer Logic:

Maslow's hierarchy requires that lower-level needs be satisfied before higher-level needs become motivators. Offering performance bonuses (esteem/achievement level) to someone who lacks job security (safety level) misapplies the hierarchy — the employee's dominant need is safety, so bonuses will not effectively motivate until that foundational need is met.

Mathematics QUESTION #981

Question 10099

Let $E:\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1,\ a>b$ and $H:\dfrac{x^2}{A^2}-\dfrac{y^2}{B^2}=1$. Let the distance between the foci of $E$ and the foci of $H$ be $2\sqrt{3}$. If $a-A=2$ and the ratio of eccentricities of $E$ and $H$ is $\dfrac{1}{3}$, then the sum of the lengths of their latus rectums is equal to:

10
9
8✔️
7

Correct Answer Logic:

Let $e_E=e$ and $e_H=3e$. Focal distances: $2ae=2\sqrt{3}\Rightarrow ae=\sqrt{3}$ and $2Ae_H=2\sqrt{3}\Rightarrow 3Ae=\sqrt{3}\Rightarrow Ae=\frac{1}{\sqrt{3}}$. Then $\frac{a}{A}=3$ and $a-A=2\Rightarrow A=1, a=3$. So $e=\frac{\sqrt{3}}{3}=\frac{1}{\sqrt{3}}$, $b^2=a^2(1-e^2)=9\cdot\frac{2}{3}=6$. For $H$: $e_H=\sqrt{3}$, $B^2=A^2(e_H^2-1)=2$. Sum of latus rectums $=\frac{2b^2}{a}+\frac{2B^2}{A}=\frac{12}{3}+\frac{4}{1}=4+4=8$.

Law QUESTION #9679

Question 10100

Under Article 37, a confession made by an accused person is irrelevant in criminal proceedings if it was caused by inducement, threat or promise — from whom must such inducement come?

Any person
A co-accused
A person in authority✔️
A police officer only

Correct Answer Logic:

Article 37 specifies that the inducement, threat or promise must proceed from 'a person in authority' and must be sufficient in the Court's opinion to give the accused reasonable grounds for making the confession.
