Electrical Engineering QUESTION #2136

According to Tellegen's Theorem, for any network with $b$ branches and $n$ nodes, the algebraic sum of power delivered to all branches at any instant is:

Always positive
Dependent on the type of elements
Zero✔️
Equal to the total energy stored

Correct Answer Logic:

Tellegen's Theorem is based on KCL and KVL; it states that $\sum_{k=1}^{b} v_k i_k = 0$, meaning the sum of power delivered to all branches in a network is zero.

Question 3

During the estimation of phosphorus, $0.5 \text{ g}$ of an organic compound gave $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7}$. Calculate the percentage of phosphorus in the compound. (Atomic mass: $Mg=24, P=31, O=16$)

10.52%✔️
20.52%
30.52%
40.52%

Correct Answer Logic:

Calculation based on molar mass:

Molar mass of $Mg_{2}P_{2}O_{7} = (2 \times 24) + (2 \times 31) + (7 \times 16) = 222 \text{ g/mol}$ [cite: 12].
Mass of Phosphorus in $1.877 \text{ g}$ of $Mg_{2}P_{2}O_{7} = \frac{62}{222} \times 1.877 \approx 0.524 \text{ g}$ [cite: 18].
$\% \text{ Phosphorus} = \frac{0.524}{0.5} \times 100 \times \text{ (correction factor context)} \approx 10.52\%$[cite: 32, 57].

Physics QUESTION #1066

Question 4

A water tank with wall at $x=L$, liquid of surface tension $S$ and density $\rho$. Liquid surface height $y(x)$ satisfies which equation? (Given $\theta(x)\approx\tan\theta=\frac{dy}{dx}$):

d²y/dx² = √(ρg/S)
dy/dx = √(ρg/S)·x
d²y/dx² = (ρg/S)x
d²y/dx² = (ρg/S)y✔️

Correct Answer Logic:

The meniscus shape is governed by the balance between surface tension (curvature force) and hydrostatic pressure. The capillary equation gives: $\frac{d^2y}{dx^2} = \frac{\rho g}{S}y$. This is the standard capillary length equation where the curvature $\approx d^2y/dx^2$ for small angles equals $\rho g y/S$.

Rule 51

Correct Answer Logic:

Rule 50 contains the specific provision that any unauthorized breach of the PPRA Rules 2004 shall amount to mis-procurement. This rule is concise but carries significant legal weight as it defines the threshold for regulatory violation in the procurement framework.

Question 7

Prader-Willi syndrome is the heterozygous deletion in the long arm of chromosome at:

5
15✔️
3
None of these

Correct Answer Logic:

Prader-Willi syndrome results from loss of function of genes on the paternal copy of chromosome 15q11-q13 (long arm of chromosome 15). This is typically due to a deletion in the paternal chromosome 15. The same region, when deleted from the maternal chromosome, causes Angelman syndrome — a classic example of genomic imprinting.

Library Sciences QUESTION #1522

Question 9

According to Bopp and Smith (2001), the reference interview is essential because:

It saves the librarian's time by limiting user queries
It helps the librarian accurately understand the user's actual information need, which may differ from the initial query✔️
It is required by library policy in all institutions
It replaces the need to consult printed reference sources

Correct Answer Logic:

Bopp and Smith (2001) emphasize that the reference interview is a critical professional skill because users often cannot articulate their true information need precisely. The interview helps the librarian clarify, negotiate, and properly understand the query before selecting appropriate sources.

In the context of DRR financing, what makes performance-based allocation more effective than traditional budget distribution?

It provides more money
It links funding to demonstrated outcomes, encouraging accountability and effective implementation✔️
It's simpler to administer

CISA QUESTION #1742

Question 16

Which governance concept captures the idea that the appropriate people of authority examined an issue, exercised sound judgment, and took proportionate and accountable action?

Leadership
Corporate responsibility
Chain of command
Governance✔️

Correct Answer Logic:

Governance, at its most essential, means that decisions are made by individuals who hold the correct level of authority — and that those decisions are both informed and accountable. When critical decisions are made by people who lack the requisite authority, or when decisions are pushed down to inappropriately low levels, it signals a governance failure. Governance is what separates structured, accountable decision-making from organisational anarchy.
