Civil Engineering QUESTION #6643

For a beam with $b=12$ in, $d=20$ in, and $f'_c=4000$ psi, what is the nominal shear strength provided by concrete ($V_c$) using the simplified ACI formula?

20,000 lbs
30,357 lbs✔️
45,200 lbs
15,180 lbs

Correct Answer Logic:

$V_c = 2\lambda\sqrt{f'_c}b_w d = 2 \times 1 \times \sqrt{4000} \times 12 \times 20 \approx 2 \times 63.25 \times 240 = 30,360$ lbs.

Administration QUESTION #9588

Question 3582

An organization's strategic analysis reveals high industry attractiveness but weak internal competitive position. Using the GE-McKinsey matrix, what strategy is recommended, and what does this imply for resource allocation?

Invest and grow — the attractive industry justifies full resource commitment despite internal weakness
Selective investment/manage for earnings — the organization should invest in specific areas where it can build competitive strength while protecting existing positions, rather than committing fully or divesting✔️
Harvest and divest — attractive industries are too competitive for weak players; the organization should exit before market position deteriorates further
Hold position — the organization should maintain current resource allocation and wait for the competitive environment to shift favorably

Correct Answer Logic:

In the GE-McKinsey nine-cell matrix, high industry attractiveness + low business strength falls in the 'Selective Growth/Earn' zone — the organization should not invest uniformly (too weak) nor exit (industry is attractive), but selectively build strengths in specific segments where competitive advantage is achievable. This is the key insight distinguishing GE-McKinsey from simpler 2×2 frameworks like BCG.

Physics and Math QUESTION #774

Question 3584

If $\dfrac{dy}{dx} = 2x$, then the equation becomes:

$y = x^2 - 2x - 3$
$y = x^2 - 2x + 3$✔️
$y = x^2 + 2x - 3$
None

Correct Answer Logic:

Integrating: $y = \int 2x\, dx = x^2 + C$. With appropriate constant the form $y = x^2 - 2x + 3$ is selected in the paper.

Constitutional Law QUESTION #5827

Question 3586

Congress passes a law allowing the President to 'cancel' specific line items in an appropriations bill after signing the bill into law. This is known as a 'Line Item Veto.' Is this constitutional?

Yes, because it helps the President 'take care' that the laws are faithfully executed and prevents waste.
Yes, provided the President notifies Congress of each cancellation.
No, because it allows the President to unilaterally amend a law, violating the Presentment Clause.✔️
No, because it violates the 'General Welfare' clause of the Taxing and Spending power.

Correct Answer Logic:

In Clinton v. City of New York, the Court struck down the Line Item Veto Act because it essentially allowed the President to create a different law than the one passed by Congress, bypassing the legislative process required by Article I.

CISA QUESTION #6864

Question 3590

An auditor reviews key performance indicators for IT service desk and finds that the primary metric is 'number of tickets closed per day' with staff bonuses tied to this metric. What is the PRIMARY risk of this metric design?

Insufficient metrics
Incentivizes quantity over quality—staff may close tickets without proper resolution✔️
Excessive focus on efficiency
Lack of customer satisfaction measures

Correct Answer Logic:

Metrics that reward quantity without quality drive dysfunctional behavior. Tying bonuses to tickets closed incentivizes staff to close tickets quickly without proper resolution, leading to recurring problems, poor service quality, and customer dissatisfaction. Effective metrics must balance quantity, quality, and customer satisfaction.

Physics QUESTION #4381

Question 3591

The unit of temperature coefficient of resistivity is:

$\dfrac{1}{C}$
$\dfrac{1}{K}$✔️
$\dfrac{1}{A}$
$\dfrac{1}{\Omega}$

Correct Answer Logic:

Temperature coefficient of resistivity $\alpha$ is defined by $\rho = \rho_0(1 + \alpha \Delta T)$. For dimensional consistency, $\alpha = \dfrac{\Delta\rho}{\rho_0 \cdot \Delta T}$, so its unit is $K^{-1}$ or $\dfrac{1}{K}$.

Biology Zoology Botany QUESTION #1361

Question 3592

The phase of mitosis in which chromosomes align at the cell's equator is called:

Anaphase
Telophase
Metaphase✔️
Prophase

Correct Answer Logic:

During metaphase (the middle phase of mitosis), chromosomes become maximally condensed and are aligned along the cell's equatorial plane (metaphase plate) by spindle fibres attached to the centromeres (kinetochores). This alignment ensures accurate segregation of sister chromatids to the two daughter cells in the subsequent anaphase.

Which of the following factors influence the impact of interference on learning?

The nature of the material being learned
The organization and meaningfulness of the information learned
The type of activity that follows studying
All of the above✔️

Correct Answer Logic:

Interference is affected by all three: the nature of material (similar material produces more interference), organization and meaningfulness (well-organized material resists interference better), and post-learning activity (similar tasks cause retroactive interference).

MBBS QUESTION #10308

Question 3599

Which amino acid contains a thiol (sulfhydryl, -SH) side chain capable of forming disulfide bonds that help stabilize tertiary and quaternary protein structure?

Cysteine✔️
Serine
Threonine
Methionine

Correct Answer Logic:

Cysteine's thiol group can be oxidized to form a disulfide bond (cystine) with another cysteine residue, an important covalent cross-link stabilizing protein folding (e.g., in insulin and immunoglobulins); methionine also contains sulfur but as a thioether, which does not form disulfide bonds.

$38^\circ\text{C}$
$40^\circ\text{C}$✔️
$42^\circ\text{C}$

Correct Answer Logic:

Formula: $C = (F - 32) \times 5/9$. $(104 - 32) = 72 \times 5/9 = 40^\circ\text{C}$.
