Agronomy QUESTION #2035

Question 1383

The optimum harvest index (HI) of modern high-yielding wheat varieties compared to traditional tall varieties is higher because:

Modern varieties produce more total biomass per unit area
Modern varieties partition a greater proportion of total biological yield into the economic yield (grain), with HI values of 0.45–0.55 vs 0.30–0.35 in traditional varieties✔️
Modern varieties have shorter grain-filling periods, reducing respiration losses
Modern varieties have thicker stems that store more assimilates

Correct Answer Logic:

Harvest Index = Economic yield / Biological yield. Green Revolution breeding shifted assimilate partitioning toward grain by reducing stem height (dwarfing genes Rht1, Rht2), increasing HI from ~0.30 in tall varieties to 0.45–0.55 in semi-dwarf modern varieties — the primary mechanism behind yield gains.

Tourism & Hospitality Management QUESTION #1614

Question 1384

In the Cultural Tourism course, 'living cultural heritage' is distinguished from 'archaeological heritage' primarily on which basis?

Living cultural heritage refers to government-protected monuments; archaeological heritage refers to privately owned sites
Living cultural heritage comprises active, ongoing cultural practices, traditions, and expressions still practiced by communities; archaeological heritage refers to physical remains of past civilizations✔️
Living cultural heritage is found only in rural areas; archaeological heritage is found only in urban museums
Living cultural heritage has commercial value; archaeological heritage has only academic value

Correct Answer Logic:

Module 1 of the Cultural Tourism course explicitly distinguishes Living Cultural Heritage (active traditions, performing arts, festivals, crafts still practiced by communities) from Archaeological Heritage (physical material remains of past civilizations). This distinction underlies UNESCO's frameworks for intangible vs. tangible heritage management.

Mathematics QUESTION #7432

Question 1385

Two poles standing on horizontal ground are of heights 5 m and 10 m respectively. The line joining their tops makes an angle of 15° with the ground. Then the distance (in m) between the poles is:

$5(2+\sqrt{3})$✔️
$5(\sqrt{3}+1)$
$\frac{5}{2}(2+\sqrt{3})$
$10(\sqrt{3}-1)$

Correct Answer Logic:

Let the distance between poles be $d$. The height difference is $10-5=5$ m. Using trigonometry: $\tan(15°) = \frac{5}{d}$. We know $\tan(15°) = 2-\sqrt{3}$ (from $\tan(45°-30°)$ formula). Therefore, $d = \frac{5}{2-\sqrt{3}} = \frac{5(2+\sqrt{3})}{(2-\sqrt{3})(2+\sqrt{3})} = \frac{5(2+\sqrt{3})}{4-3} = 5(2+\sqrt{3})$.

Boilers Mechanical Engineering QUESTION #2548

Question 1389

The principal axes of a cross-section are axes about which:

The moment of inertia is maximum only
The product of inertia is zero AND the moments of inertia are extreme (max/min)✔️
The polar moment of inertia is minimum
All second moments are equal

Correct Answer Logic:

Principal axes are defined by two conditions: (1) $I_{xy}=0$ (product of inertia vanishes), and (2) the second moments $I_x$ and $I_y$ attain their absolute maximum and minimum values, called principal moments of inertia.

Library Sciences QUESTION #1510

Question 1392

The principle of 'literary warrant' in subject heading construction means that:

Headings are assigned only to fiction works
New subject headings are created only when actual documents on a topic exist in the literature✔️
Headings must be in the language of the cataloguer
All headings must be approved by the Library of Congress

Correct Answer Logic:

Literary warrant is the principle that a subject heading or classification number should only be established when there is actual published literature on the topic to justify it. It grounds controlled vocabulary in existing documented knowledge.

Chemistry QUESTION #7170

Question 1399

The energy of an electron is defined by $E = -2.178 \times 10^{-18} \text{ J} (\frac{Z^{2}}{n^{2}})$. Calculate the wavelength of light necessary to excite an electron in a hydrogen atom from the ground state ($n=1$) to the first excited state ($n=2$).

$1.214 \times 10^{-7} \text{ m}$✔️
$2.816 \times 10^{-7} \text{ m}$
$6.500 \times 10^{-7} \text{ m}$
$8.500 \times 10^{-7} \text{ m}$

Correct Answer Logic:

To find the wavelength, we first calculate the energy difference:

$\Delta E = E_{2} - E_{1} = -2.178 \times 10^{-18} (\frac{1}{2^{2}} - \frac{1}{1^{2}}) \text{ J}$
$\Delta E = 2.178 \times 10^{-18} \times \frac{3}{4} = 1.6335 \times 10^{-18} \text{ J}$
Using $\lambda = \frac{hc}{\Delta E}$:
$\lambda = \frac{6.62 \times 10^{-34} \times 3 \times 10^{8}}{1.6335 \times 10^{-18}} \approx 1.214 \times 10^{-7} \text{ m}$
