Agronomy QUESTION #2053

Question 1687

The 'source–sink' relationship in crop physiology as applied to agronomic management refers to:

The relationship between irrigation source and water sink capacity of soil
The balance between photosynthetic capacity (source: leaves producing assimilates) and the capacity of storage organs (sink: grain, tuber) to accumulate dry matter, which determines yield potential✔️
The nutrient flow between organic matter source (manure) and plant nutrient sink (roots)
The relationship between rainfall source and soil water deficit (sink)

Correct Answer Logic:

In crop physiology, source = photosynthetic organs producing assimilates; sink = organs storing assimilates (grain, tubers). Yield is co-limited by both: a large source with small sink (poor grain set) wastes photosynthate; a large sink with small source (poor canopy) starves grain fill. Agronomic practices (planting density, nutrition, irrigation) manage both.

Reading and Writing (Module-1) QUESTION #5358

Question 1688

Transgenic fish have genetic material from other species. Some contain jellyfish DNA, causing them to glow. Originally created for labs in the 90s, they became pets later and are now appearing in Brazilian rivers. A student suggests their escape from farms could lead to long-term ecological damage. Which quotation from a researcher would best support the student's assertion?

'In one site in the wild where transgenic fish were observed, females outnumbered males, while in another the numbers of females and males were equivalent.'
'Though some presence of transgenic fish in the wild has been recorded, there are insufficient studies of the impact of those fish on the ecosystems into which they are introduced.'
'The ecosystems into which transgenic fish are known to have been introduced may represent a subset of the ecosystems into which the fish have actually been introduced.'
'Through interbreeding, transgenic fish might introduce the trait of fluorescence into wild fish populations, making those populations more vulnerable to predators.'✔️

Correct Answer Logic:

Option D provides a specific negative ecological outcome (vulnerability to predators) resulting from the transgenic trait entering the wild population.

Question 1689

What is $0.08$ as a percentage?

$0.08\%$
$0.8\%$
$8\%$✔️
$80\%$

Correct Answer Logic:

To convert decimal to percent, multiply by $100$. $0.08 \times 100 = 8\%$

Civil Engineering QUESTION #2116

Question 1690

For a rectangular cross-section beam, the ratio of maximum shear stress to average shear stress is:

1.0
1.5✔️
2.0
1.33

Correct Answer Logic:

For a rectangular section of width $b$ and depth $d$: maximum shear stress occurs at the neutral axis $= \dfrac{3V}{2bd} = 1.5 \times \dfrac{V}{bd}$. Average shear stress $= \dfrac{V}{bd}$. Therefore ratio $= 1.5$. This is a fundamental result derived from the shear stress distribution formula $\tau = \dfrac{VQ}{Ib}$.

Mechanical Engineering QUESTION #2477

Question 1691

A kinematic pair of the 5th class (full kinematic pair) such as a revolute (pin) joint in a planar mechanism removes how many degrees of freedom from relative motion between two links?

$1$ DOF
$2$ DOF
$5$ DOF✔️
$3$ DOF

Correct Answer Logic:

A kinematic pair of the $j$th class removes $j$ DOF from the relative motion of the connected links. A 5th-class pair removes 5 DOF, leaving 1 DOF.

Physics QUESTION #986

Question 1692

For a short dipole placed at origin $O$, the dipole moment $P$ is along the $x$-axis. If the electric potential and electric field at $A$ (on the $x$-axis at distance $r$) are $V_0$ and $E_0$ respectively, then the electric potential and electric field at point $B$ on the $y$-axis at distance $2r$ are:

$V_0$ and $\dfrac{E_0}{4}$
zero and $\dfrac{E_0}{16}$✔️
zero and $\dfrac{E_0}{8}$
$\dfrac{V_0}{2}$ and $\dfrac{E_0}{16}$

Correct Answer Logic:

On the equatorial axis (y-axis): $V=0$ always. $E_{axial}=\frac{2kP}{r^3}$ and $E_{equatorial}=\frac{kP}{r^3}$. At distance $r$: $E_0=\frac{2kP}{r^3}$. At distance $2r$ on equatorial: $E=\frac{kP}{(2r)^3}=\frac{kP}{8r^3}=\frac{E_0}{16}$. So: zero and $\frac{E_0}{16}$.

Library Sciences QUESTION #1539

Question 1693

In library staffing, 'job analysis' is best defined as:

The process of advertising a vacant position
A systematic process of collecting information about the duties, responsibilities, skills, and context of a job✔️
A performance appraisal method
A technique for scheduling staff shifts

Correct Answer Logic:

Job analysis is a systematic process of gathering detailed information about a position — its tasks, responsibilities, required knowledge, skills, and working conditions. It forms the foundation for writing job descriptions, recruiting, training, and performance evaluation in library management.

English QUESTION #2767

Question 1694

Find the word OPPOSITE IN MEANING to 'Verbose'.

Talkative
Concise✔️
Lengthy
Wordy

Correct Answer Logic:

'Verbose' means using more words than needed (wordy). Its antonym is 'Concise', which means giving a lot of information clearly and in few words. 'Talkative', 'Lengthy', and 'Wordy' are synonyms of verbose.

Physics QUESTION #1042

Question 1696

To an AC supply of 220 V at 50 Hz: $R=20\ \Omega$, capacitive reactance $X_C=25\ \Omega$, inductive reactance $X_L=45\ \Omega$. Current and phase angle are:

15.6 A and 30°
15.6 A and 45°
7.8 A and 30°
7.8 A and 45°✔️

Correct Answer Logic:

Impedance: $Z=\sqrt{R^2+(X_L-X_C)^2}=\sqrt{400+(45-25)^2}=\sqrt{400+400}=\sqrt{800}=20\sqrt{2}\ \Omega$. Current $=\frac{220}{20\sqrt{2}}=\frac{220}{28.28}\approx7.78\ \text{A}\approx7.8\ \text{A}$. Phase angle: $\tan\phi=\frac{X_L-X_C}{R}=\frac{20}{20}=1\Rightarrow\phi=45°$.

Correct Answer Logic:

Circumference $= \pi d = 3.14 \times 20 = 62.8$ cm.

Question 1698

Which word is a PREPOSITION in the sentence: 'The cat is sitting under the table.'?

cat
sitting
under✔️
table

Correct Answer Logic:

A preposition shows the relationship between a noun/pronoun and another word in the sentence. 'Under' shows the spatial relationship between 'cat' and 'table'.
