MBBS QUESTION #10197
Question 3064
The appendix receives its blood supply from the appendicular artery, itself a branch of which vessel β€” and being an end artery, why does this predispose to gangrenous appendicitis when obstructed?
  • Ileocolic artery, whose appendicular branch has no significant collateral supplyβœ”οΈ
  • Right colic artery, which has rich collateral anastomoses
  • Middle colic artery, with dual supply from the SMA and coeliac trunk
  • Superior mesenteric artery directly, with abundant collaterals
Correct Answer Logic:
The appendicular artery is a branch of the ileocolic artery (itself from the superior mesenteric artery) and behaves as an end artery with little collateral supply; luminal obstruction (e.g., by a faecolith) raising intraluminal pressure can compromise this single blood supply, leading rapidly to ischemia, gangrene, and perforation.

Boilers Mechanical Engineering QUESTION #2432
Question 3065
In natural (free) convection, the key dimensionless parameter governing the flow is the Rayleigh number \(Ra\), defined as:
  • \(Ra = Gr \cdot Pr = \frac{g\beta\Delta T L^3}{\nu^2}\cdot Pr = \frac{g\beta\Delta T L^3}{\nu\alpha}\)βœ”οΈ
  • \(Ra = Re \cdot Pr\)
  • \(Ra = Nu / Pr^{1/3}\)
  • \(Ra = Gr / Pr\)
Correct Answer Logic:
Rayleigh number: \(Ra=Gr\cdot Pr=\frac{g\beta\Delta TL^3}{\nu\alpha}\) where \(\beta\) is thermal expansion coefficient, \(\nu\) is kinematic viscosity, \(\alpha\) is thermal diffusivity.

Physics QUESTION #7087
Question 3068
A material has density $\rho$ and bulk modulus $K$. What is the increase in density when a uniform pressure $P$ is applied?
  • $\frac{\rho P}{K}$βœ”οΈ
  • $\frac{\rho K}{P}$
  • $\frac{K}{\rho P}$
  • $\frac{PK}{\rho}$
Correct Answer Logic:

Bulk modulus $K = \rho \frac{dP}{d\rho}$.

  • Rearranging for change in density $d\rho$: $d\rho = \frac{\rho dP}{K}$
  • Given $dP = P$, the increase is $\frac{\rho P}{K}$.

Accounting & Finance QUESTION #9631
Question 3069
The Separate Entity Concept requires that:
  • The business must be legally incorporated as a separate company
  • For accounting purposes, the transactions of the business are recorded independently of the personal transactions of its ownerβœ”οΈ
  • Only a joint-stock company qualifies as a separate entity
  • The owner cannot withdraw funds from the business under any circumstances
Correct Answer Logic:
The Separate Entity Concept is an accounting assumption (not a legal requirement) applicable to all forms of business β€” sole proprietorship, partnership, and companies alike. It means that from an accounting perspective, the business is treated as a distinct entity separate from its owners. The owner's personal transactions are not recorded in the business books.

Maths QUESTION #7995
Question 3070
\(3^{72/100}\) written as a fraction is:
  • 3.72
  • 37.2
  • 0.372βœ”οΈ
  • 372
Correct Answer Logic:
\(3^{72/100} = 3.72\) β€” wait, this is a notation question. \(3\tfrac{72}{100} = 3 + 0.72 = 3.72\) as a decimal, or \(\dfrac{372}{100} = 0.372\) when simplified... The answer key gives C (0.372). Note: \(\dfrac{372}{100} = 3.72\) not 0.372. Answer key may contain a typo; the mixed number \(3\tfrac{72}{100} = 3.72\).

Verbal Reasoning QUESTION #8065
Question 3071

Which of the following is equal to $\frac{1}{4}$ of 0.01 percent?
  • $0.000025$βœ”οΈ
  • $0.00025$
  • $0.0025$
  • $0.25$
Correct Answer Logic:

First, convert 0.01 percent to a decimal: $0.01\% = \frac{0.01}{100} = 0.0001$

Now find $\frac{1}{4}$ of this value:

$\frac{1}{4} \times 0.0001 = 0.000025$

Therefore, the answer is $0.000025$.

Biology QUESTION #7244
Question 3073
In the following matching table, identify the correct combination of crop, its disease, and the corresponding pathogen:
CropDiseasePathogen
(1)CitrusCankerPseudomonas rubrilineans
(2)PotatoLate blightFusarium udum
(3)BrinjalRoot-knotMeloidogyne incognita
(4)Pigeon peaSeed gallPhytophthora infestans
  • Citrus β€” Canker β€” Pseudomonas rubrilineans
  • Potato β€” Late blight β€” Fusarium udum
  • Brinjal β€” Root-knot β€” Meloidogyne incognitaβœ”οΈ
  • Pigeon pea β€” Seed gall β€” Phytophthora infestans
Correct Answer Logic:
The correct match is Brinjal β€” Root-knot β€” Meloidogyne incognita. Meloidogyne is a nematode that causes root-knot disease in many vegetables including brinjal. Late blight of potato is caused by Phytophthora infestans, not Fusarium. Citrus canker is bacterial (Xanthomonas).

Biology QUESTION #7238
Question 3076
Moss peat is used as a packing material for sending flowers and live plants to distant places because:
  • It reduces transpiration
  • It serves as a disinfectant
  • It is easily available
  • It is hygroscopicβœ”οΈ
Correct Answer Logic:
Moss peat (mainly Sphagnum) is hygroscopic β€” it absorbs and retains large amounts of water. This keeps plants moist during transport. It can hold water up to 18–20 times its dry weight, making it ideal packing for live plant material.

Physics QUESTION #1183
Question 3077
The charging and discharging behavior of an ideal RLC circuit is:
  • Simple harmonicβœ”οΈ
  • Linear
  • Elliptical
  • Unpredictable
Correct Answer Logic:
In an ideal LC (or lightly damped RLC) circuit, the charge on the capacitor and current in the inductor oscillate sinusoidally β€” this is simple harmonic oscillation. The differential equation for an LC circuit is \(L\frac{d^2q}{dt^2} + \frac{q}{C} = 0\), identical in form to the SHM equation \(\ddot{x} + \omega^2 x = 0\).

Physics QUESTION #7091
Question 3078
Guns A and B fire bullets at $1\text{ km/s}$ and $2\text{ km/s}$. Find the ratio of the maximum areas covered on the ground.
  • 1:16βœ”οΈ
  • 1:02
  • 1:04
  • 1:08
Correct Answer Logic:

The maximum range is $R_{max} = \frac{u^2}{g}$.

  • Area covered is a circle: $A = \pi R_{max}^2 = \pi (\frac{u^2}{g})^2 \propto u^4$.
  • Ratio: $\frac{A_1}{A_2} = (\frac{u_1}{u_2})^4 = (\frac{1}{2})^4 = 1:16$.

Statistics QUESTION #1997
Question 3079
Using moments \(\mu_1' = -0.35\), \(\mu_2' = 2.09\) about \(a = 16\), the variance \(\mu_2\) (second central moment) of the distribution equals:
  • 2.09
  • 1.9675βœ”οΈ
  • 2.2125
  • 1.7
Correct Answer Logic:
Variance \(\mu_2 = \mu_2' - (\mu_1')^2 = 2.09 - (-0.35)^2 = 2.09 - 0.1225 = 1.9675\). The central moment is obtained by subtracting the squared first raw moment from the second raw moment.
