Civil Engineering QUESTION #6627

Question 2787

Which of the following describes the 'Balance Point' in a column interaction diagram?

Where the concrete reaches $\epsilon_u = 0.003$ and steel remains elastic
Where the concrete reaches $\epsilon_u = 0.003$ and tension steel simultaneously reaches yield strain $\epsilon_y$✔️
Where the axial load is zero and the section is in pure flexure
Where the eccentricity of the load is zero

Correct Answer Logic:

The balanced strain condition occurs when the tension reinforcement reaches its yield strain at the same time the concrete reaches its assumed ultimate strain of 0.003.

Electrical Engineering QUESTION #2185

Question 2788

A $100\,\text{kVA}$, $11\,\text{kV}/400\,\text{V}$ transformer has iron losses $P_i = 500\,\text{W}$ and full-load copper losses $P_{cu} = 1200\,\text{W}$. The efficiency at half full-load and $0.8$ pf lagging is:

$98.0\%$✔️
$96.1\%$
$97.3\%$
$94.5\%$

Correct Answer Logic:

Output at half load $= 0.5\times100\times10^3\times0.8 = 40{,}000\,\text{W}$. Cu loss $= (0.5)^2\times1200 = 300\,\text{W}$. Iron loss $= 500\,\text{W}$ (constant). $\eta = \frac{40000}{40000+800}\times100 = \frac{40000}{40800} \approx 98.0\%$.

Boilers Mechanical Engineering QUESTION #2383

Question 2789

A necessary and sufficient condition for a linear feedback system to be stable is that:

All poles of the closed-loop transfer function have positive real parts
All poles of the closed-loop transfer function have negative real parts✔️
The gain $K$ is greater than 1
The system has no zeros in the right-half s-plane

Correct Answer Logic:

Stability condition: all poles of the closed-loop transfer function must have negative real parts (lie in the left-half s-plane). If any pole has a positive real part, the response grows without bound (unstable).

Journalism / Mass Communication QUESTION #6392

Question 2794

The concept of static meanings in language refers to which communication problem?

The meaning of words changes so rapidly that communication becomes impossible within a few years
Words become attached to people or situations and continue to carry those meanings long after circumstances have changed, because language lacks a dynamic mechanism for updating associations✔️
Static meanings are beneficial because they provide stability and predictability in communication
Static meanings refer to the way religious texts preserve the original meaning of words across millennia

Correct Answer Logic:

Static meanings is one of the behaviours of language that the textbook identifies as a communication problem. Languages attach meanings to words and associate characteristics with people, places, or groups — and these associations can persist long after they are no longer accurate or fair. The textbook gives these illustrative examples:

A university classmate once regarded as “nuts” is still referred to as such by friends even years after he has matured and changed
A traveller cheated once in a foreign country continues to call all people of that nation “cheats” decades later
Historical ruling tribes described with certain characteristics have their descendants judged by those same labels for generations

This is contrasted with natural sciences like physics or chemistry, where measurements change objectively as conditions change. Language has no such automatic update mechanism — human bias preserves outdated associations, harming communication and perpetuating injustice.

Dairy Food Science and Technology QUESTION #5973

Question 2795

In spray drying, 'lecithin treatment' of the powder after drying is performed to produce:

Instantly soluble (instantized) powder with improved dispersibility in cold water✔️
A powder with higher fat content
A powder with reduced microbial count
A powder with lower $T_g$ for better flow

Correct Answer Logic:

Lecithin (phosphatidylcholine) is applied to agglomerated whole milk powder to make it 'instant' — rapidly dispersible and wettable in cold water. Lecithin's amphiphilic nature reduces the hydrophobic fat-rich surface tension, allowing water to penetrate powder granules quickly.

Math Physics Chemistry Biology QUESTION #4314

Question 2796

A person in hot weather is unable to maintain body temperature. Which physiological process has failed?

Vasodilation & sweating✔️
Vasoconstriction
Shivering
Renin secretion

Correct Answer Logic:

In hot weather, the body cools itself through vasodilation (increases heat loss from skin) and sweating (evaporative cooling). Failure of these mechanisms leads to hyperthermia.

Mathematics QUESTION #7440

Question 2797

All the students of a class performed poorly in Mathematics. The teacher decided to give grace marks of 10 to each of the students. Which of the following statistical measures will not change even after the grace marks were given?

mean
median
mode
variance✔️

Correct Answer Logic:

When a constant is added to all observations, the mean, median, and mode all increase by that constant. However, variance (and standard deviation) measure the spread of data around the mean. Since all values shift by the same amount, the spread remains unchanged. Therefore, variance does not change when grace marks are added uniformly to all students.

Question 2798

The lactose content of cow's whole milk is approximately:

$2\text{–}3\%$
$4.5\text{–}5\%$✔️
$7\text{–}8\%$
$10\text{–}12\%$

Correct Answer Logic:

Lactose constitutes approximately $4.5\text{–}5.0\%$ (w/v) of bovine milk. It is a disaccharide of glucose and galactose linked by a $\beta$-$1{,}4$-glycosidic bond.

Chemistry QUESTION #7415

Question 2799

The reason for lanthanoid contraction is:

Negligible screening effect of f-orbitals (poor shielding by f-electrons)✔️
Increasing nuclear charge
Decreasing nuclear charge
Decreasing screening effect

Correct Answer Logic:

Lanthanoid contraction: The 14 lanthanoids show a gradual decrease in atomic/ionic radius from La to Lu.

Cause: The 4f electrons have a poor shielding effect (they cannot effectively shield each other or outer electrons from the increasing nuclear charge). As protons are added (Z increases from 58 to 71) with poor f-electron shielding, the effective nuclear charge experienced by outer electrons steadily increases, pulling them inward.

Reading and Writing (Module-1) QUESTION #5407

Question 2800

Mycorrhizal fungi in soil benefits many plants, substantially increasing the mass of some. A student conducted an experiment to illustrate this effect. The student chose three plant species for the experiment, including two that are mycorrhizal hosts (species known to benefit from mycorrhizal fungi) and one nonmycorrhizal species (a species that doesn't benefit from and may even be harmed by mycorrhizal fungi). The student then grew several plants from each species both in soil containing mycorrhizal fungi and in soil that had been treated to kill mycorrhizal and other fungi. After several weeks, the student measured the plants' average mass and was surprised to discover that _______. Which choice most effectively uses data from the table to complete the statement?

broccoli grown in soil containing mycorrhizal fungi had a slightly higher average mass than broccoli grown in soil that had been treated to kill fungi.✔️
corn grown in soil containing mycorrhizal fungi had a higher average mass than broccoli grown in soil containing mycorrhizal fungi.
marigolds grown in soil containing mycorrhizal fungi had a much higher average mass than marigolds grown in soil that had been treated to kill fungi.
corn had the highest average mass of all three species grown in soil that had been treated to kill fungi while marigolds had the lowest.

Correct Answer Logic:

The student would be surprised that broccoli (a nonmycorrhizal species) had slightly higher mass with fungi (7.5g vs 7g), contradicting the expectation that fungi wouldn't help or might harm it.
