Mathematics QUESTION #6011

Question 9083

Identify the curve from the family defined by $(x^2-y^2)\,dx + 2xy\,dy = 0$ that passes through the point $(1,1)$.

A circle centred on the $x$-axis
An ellipse with major axis along the $y$-axis
A circle centred on the $y$-axis✔️
A hyperbola with transverse axis along the $x$-axis

Correct Answer Logic:

Rewrite: $\frac{dy}{dx} = \frac{y^2-x^2}{2xy}$. This is a homogeneous ODE. Let $y=vx$:

$\frac{1-v^2}{2v}dx + x\,dv/... $

After solving, the general solution is $x^2 + y^2 = Cy$ (circles with centres on the $y$-axis).

Substituting $(1,1)$: $1+1=C\cdot1 \Rightarrow C=2$, giving $x^2+y^2=2y$, i.e. $x^2+(y-1)^2=1$.

This is a circle centred on the $y$-axis at $(0,1)$.

Biology Zoology Botany QUESTION #1364

Question 9086

Which group of organisms is known for having chloroplasts in every cell?

Fungi
Algae✔️
Bryophytes
Lichens

Correct Answer Logic:

Algae contain chloroplasts in every photosynthetic cell of their thallus. Algal chloroplasts come in diverse shapes (cup-shaped, ribbon-like, stellate) and contain photosynthetic pigments. Fungi have no chloroplasts at all (they are heterotrophs). Bryophytes have chloroplasts in their green cells but not every cell (e.g., rhizoids lack them). Lichens are fungal-algal symbioses.

Mathematics QUESTION #1284

Question 9087

The contour integral $\oint_C f(Z)\,dZ$ where $C$ is a simple closed contour and $f$ is analytic everywhere inside and on $C$ equals:

1
2$\pi i$
$\pi i$

Correct Answer Logic:

Cauchy's Integral Theorem states that if $f$ is analytic on and inside a simple closed contour $C$, then $\oint_C f(Z)\,dZ=0$. This is a fundamental result in complex analysis.

Pharmacology and Toxicology QUESTION #3860

Question 9089

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).

Its counterpart jurisdiction was transferred to the newly created Federal Constitutional Court under Articles 175B-175L.

Geology QUESTION #10644

Question 9096

Ox-bow lakes are formed as a direct result of:

Seasonal flooding of river banks
Intense river meandering and eventual cutoff of meander loops✔️
Lateral erosion of river banks
Downstream flow velocity increase

Correct Answer Logic:

Ox-bow lakes form in mature rivers with highly sinuous meanders. As a meander loop becomes extremely curved, the river eventually cuts through the narrow neck of the meander during a flood, taking the shorter path. The abandoned meander loop is cut off and becomes an isolated, crescent-shaped ox-bow lake. Over time, it may fill with sediment and vegetation to become an ox-bow swamp or marsh.

Accounting & Finance QUESTION #6048

Question 9097

Nishat Textiles has the following data for the current year:
Current ratio $= 2:1$; Average age of inventory $= 60$ days; Average collection period $= 30$ days; Average payable period $= 40$ days.
Calculate the Cash Conversion Cycle (CCC).

50 days✔️
90 days
78 days
42 days

Correct Answer Logic:

The Cash Conversion Cycle formula is:

$\text{CCC} = \text{Days Inventory Outstanding} + \text{Days Sales Outstanding} - \text{Days Payable Outstanding}$

$= 60 + 30 - 40 = \mathbf{50 \text{ days}}$

The CCC measures how long it takes a firm to convert its investments in inventory and other resources into cash flows from sales. A shorter CCC generally indicates better liquidity management.

Question 9099

Which part of the brain is responsible for maintaining posture balance and coordination of voluntary movements?

Cerebrum
Cerebellum✔️
Medulla oblongata
Hypothalamus

Correct Answer Logic:

The cerebellum ('little brain') is responsible for coordinating voluntary movements, maintaining posture, and balance. It receives sensory input about the body's position and motor commands from the cerebrum, then fine-tunes motor activity.

Physics QUESTION #1058

Question 9100

An electron (mass $9\times10^{-31}\ \text{kg}$, charge $1.6\times10^{-19}\ \text{C}$) moves at $c/100$ in field $B=9\times10^{-4}\ \text{T}$. Electric field $E$ to prevent deflection:

E parallel to B, magnitude $27\times10^2\ \text{V/m}$
E parallel to B, magnitude $27\times10^4\ \text{V/m}$
E perpendicular to B, magnitude $27\times10^4\ \text{V/m}$✔️
E perpendicular to B, magnitude $27\times10^2\ \text{V/m}$

Correct Answer Logic:

For no deflection: electric force must balance magnetic force. $qE=qvB\Rightarrow E=vB=\frac{3\times10^8}{100}\times9\times10^{-4}=3\times10^6\times9\times10^{-4}=27\times10^2\ \text{V/m}$. E must be perpendicular to B (to oppose magnetic force direction). So E perpendicular to B, magnitude $27\times10^2\ \text{V/m}$ = option (4).
