Geography QUESTION #6323

Question 1802

In medical geography, the distance-decay effect on healthcare utilization suggests that:

Disease prevalence decreases with distance from pollution sources
Healthcare facility usage decreases as patient distance from facility increases✔️
Epidemic spread slows with distance from origin
Healthcare quality declines in remote areas

Correct Answer Logic:

Distance-decay in healthcare access describes the inverse relationship between distance and utilization: people are less likely to use healthcare facilities as distance increases, even controlling for need. This reflects travel costs, time, and effort creating a friction of distance.

Civil / Architecture QUESTION #2367

Question 1808

In open channel hydraulics, the specific energy $E$ at a cross-section with depth $y$, velocity $V$, and discharge per unit width $q$ is given by $E = y + \dfrac{V^2}{2g}$. The critical depth $y_c$ for a rectangular channel, at which specific energy is minimum for a given discharge $q$, is:

$y_c = \sqrt[3]{\dfrac{q}{g}}$
$y_c = \sqrt[3]{\dfrac{q^2}{g}}$✔️
$y_c = \sqrt{\dfrac{q^2}{g}}$
$y_c = \left(\dfrac{q^2}{g}\right)^{2/3}$

Correct Answer Logic:

Critical depth for a rectangular channel: $y_c = \left(\dfrac{q^2}{g}\right)^{1/3} = \sqrt[3]{\dfrac{q^2}{g}}$. At critical depth, the Froude number $Fr = \dfrac{V}{\sqrt{gy}} = 1$. For $y < y_c$: supercritical flow ($Fr > 1$); for $y > y_c$: subcritical flow ($Fr < 1$). The minimum specific energy $E_{min} = \dfrac{3}{2} y_c$.

Mathematics QUESTION #975

Question 1810

The perpendicular distance of the line $\dfrac{x-1}{2}=\dfrac{y+2}{-1}=\dfrac{z+3}{2}$ from the point $P(2,-10,1)$ is:

6
$5\sqrt{2}$
$4\sqrt{3}$
$3\sqrt{5}$✔️

Correct Answer Logic:

Direction vector $\vec{d}=(2,-1,2)$. Point on line $A=(1,-2,-3)$. $\vec{AP}=(1,-8,4)$. $|\vec{AP}|^2=1+64+16=81$. $\vec{AP}\cdot\vec{d}=2+8+8=18$. $|\vec{d}|^2=9$. Distance$^2=81-\frac{324}{9}=81-36=45$. Distance$=\sqrt{45}=3\sqrt{5}$.

Physics QUESTION #7304

Question 1812

A body in one-dimensional motion has zero speed at some instant. At that instant it must have:

Zero velocity✔️
Zero acceleration
Non-zero velocity
Non-zero acceleration

Correct Answer Logic:

Speed is the magnitude of velocity. If speed $= 0$, then $|v| = 0 \Rightarrow v = 0$.

Acceleration need not be zero — for example, a ball at its highest point has $v = 0$ but acceleration $= g$ downward.

Guaranteed: zero velocity only.

Pharmacology and Toxicology QUESTION #3860

Question 1813

Which pharmacological effect would be expected following systemic administration of atropine?

Constriction of the pupil
Increased gastric motility
Micturition
Increased heart rate✔️

Correct Answer Logic:

Atropine is a competitive muscarinic antagonist. By blocking parasympathetic (vagal) tone at the sinoatrial node, it removes the brake on heart rate, causing tachycardia (increased heart rate).

Question 1814

In the brain, why can only lipid-soluble drugs cross the capillary endothelial cells into the CNS?

Due to large slit junctions
Because the basement membrane is exposed
Due to the absence of slit junctions✔️
Because of active transport of all water-soluble drugs

Correct Answer Logic:

Brain capillaries have continuous endothelial cells with no slit junctions, creating a barrier for polar molecules.

Biology QUESTION #7269

Question 1820

Nitrogen fixation in root nodules of Alnus is brought about by:

Frankia✔️
Azorhizobium
Bradyrhizobium
Clostridium

Correct Answer Logic:

Frankia is a filamentous actinomycete that forms nitrogen-fixing root nodules (actinorhizal nodules) in non-leguminous plants like Alnus (alder), Casuarina, and Ceanothus. Rhizobium and Bradyrhizobium nodulate legumes; Azorhizobium is stem-nodulating; Clostridium is a free-living anaerobic nitrogen fixer.
