Planning QUESTION #4925

What is the main advantage of the Gravity Model in trip distribution?

It requires minimal data
It considers both trip production and distance decay✔️
It is the fastest computational method
It eliminates the need for surveys

Correct Answer Logic:

The Gravity Model effectively considers both the attractiveness of destinations (trip production/attraction) and the impedance of distance, making it realistic for predicting trip distribution patterns.

Agriculture Economics QUESTION #11888

Question 3202

The price elasticity of supply is calculated as:

$E_s = \dfrac{\%\Delta P}{\%\Delta Q_s}$
$E_s = \dfrac{\%\Delta Q_s}{\%\Delta P}$✔️
$E_s = \%\Delta Q_s \times \%\Delta P$
$E_s = \dfrac{Q_s}{P}$

Correct Answer Logic:

Price elasticity of supply is the percentage change in quantity supplied divided by the percentage change in price: $E_s = \dfrac{\%\Delta Q_s}{\%\Delta P}$.

Business, Public administration and Policy QUESTION #10509

Question 3204

The judiciary serves as a check on government agencies primarily through:

Holding criminal trials for administrators who violate the law
Reviewing the legality of each policy proposal before enactment
Writing implementing rules on behalf of agencies
Interpreting agency mandates and reviewing the legality of agency actions✔️

Correct Answer Logic:

Courts check administrative agencies through judicial review — scrutinizing whether agency actions are intra vires (within legal authority), procedurally fair, and constitutionally sound. Courts do not pre-approve every agency rule; they respond to challenges brought before them. This power to interpret mandates and annul ultra vires actions is the judiciary's primary check on bureaucratic excess.

Physics QUESTION #1160

Question 3210

The viscosity of a fluid in motion is 1 Poise. What will be its viscosity (in Poise) when the fluid is at rest?

0.5
1✔️
2

Correct Answer Logic:

Viscosity is an intrinsic property of a fluid that depends on its temperature and nature, not on its state of motion or rest. A fluid's viscosity remains the same whether it is flowing or stationary. The viscosity is still 1 Poise at rest.

MBBS QUESTION #10178

Question 3211

A fracture of the medial epicondyle of the humerus results in a claw-hand deformity with wasting of the hypothenar muscles and interossei. Which nerve is injured?

Median nerve
Ulnar nerve✔️
Radial nerve
Axillary nerve

Correct Answer Logic:

The ulnar nerve passes directly behind the medial epicondyle in the cubital tunnel, making it vulnerable to injury there; resultant loss of the interossei and hypothenar muscles produces the characteristic ulnar claw hand (hyperextension at MCP, flexion at IP joints of the ring and little fingers).

Chemistry QUESTION #7150

Question 3212

Identify the amphoteric hydroxide among the following group 2 elements.

$Be(OH)_{2}$✔️
$Ca(OH)_{2}$
$Mg(OH)_{2}$
$Sr(OH)_{2}$

Correct Answer Logic:

Most group 2 hydroxides are basic and their basicity increases down the group. However, Beryllium ($Be$) is the first element and shows diagonal relationship with Aluminum. Due to its small size and high electronegativity, $Be(OH)_{2}$ is amphoteric, meaning it reacts with both acids and strong bases.

Chemistry QUESTION #7184

Question 3216

A metal oxide is found to have the non-stoichiometric formula $M_{0.98}O$. If the metal $M$ exists in both $M^{2+}$ and $M^{3+}$ states, calculate the percentage of the metal that exists as $M^{3+}$.

$7.01\%$
$4.08\%$✔️
$6.05\%$
$5.08\%$

Correct Answer Logic:

Applying the principle of charge neutrality for $M_{0.98}O$:

Let the number of $M^{3+}$ ions be $x$. Then $M^{2+}$ ions are $(0.98 - x)$.
Total positive charge = Total negative charge ($2$ for one $O^{2-}$).
$3x + 2(0.98 - x) = 2 \implies 3x + 1.96 - 2x = 2 \implies x = 0.04$.
Fraction of $M^{3+} = 0.04 / 0.98 \approx 0.0408$ or $4.08\%$.

Mise en Place is the menu design process; Mise en Scène is the kitchen brigade organization
Mise en Place covers billing procedures; Mise en Scène covers entertainment arrangements

Correct Answer Logic:

The Restaurant Management course (Module 2: Restaurant Facilities) covers both concepts: Mise en Place (French: 'everything in its place') refers to the pre-service preparation of all service tools, condiments, and materials, while Mise en Scène (French: 'setting the scene') refers to the aesthetic preparation of the dining environment — lighting, furniture arrangement, décor — before guests arrive.

Physics QUESTION #1159

Question 3220

The viscous force __________ the relative motion between the adjacent layers of a fluid in motion.

Opposes✔️
Never affects
Facilitates
May affect under certain conditions

Correct Answer Logic:

Viscosity is the property of a fluid by which it resists relative motion between its adjacent layers. The viscous force always opposes the relative motion (sliding) between layers, similar to friction in solids. This is described by Newton's law of viscosity: $F = \eta A \frac{dv}{dy}$.
