$\$36$
$\$84$✔️
$\$40$
$\$60$

Correct Answer Logic:

Sum of parts $= 10$. One part $= 120 / 10 = 12$. Y gets $7 \times 12 = 84$.

Question 7002

If the surface charge density of an infinite sheet increases by $25\%$, the electric field intensity:

Increases by $25\%$✔️
Increases by $50\%$
Decreases by $25\%$
Remains the same

Correct Answer Logic:

Electric field due to an infinite sheet: $E = \dfrac{\sigma}{2\varepsilon_0}$. Since $E \propto \sigma$ (direct proportion), if $\sigma$ increases by $25\%$, then $E$ also increases by $25\%$.

Question 7003

A community-based DRR program shows high participation but limited impact on actual risk reduction. What is the most likely systemic gap?

Lack of community interest
Insufficient integration with local government planning and resource allocation✔️
Poor communication strategies
Inadequate training materials

Correct Answer Logic:

Sections 4.3 and 13.4 emphasize that community participation must be coupled with devolved resources, decision-making powers, and integration into formal district-level planning. Without institutional backing and resources, community engagement alone cannot achieve substantive risk reduction.

Question 7004

The sum of three consecutive integers is $60$. What is the middle integer?

$19$
$20$✔️
$21$
$18$

Correct Answer Logic:

Let integers be $n-1, n, n+1$. Sum: $3n = 60$, so $n = 20$

Question 7005

Rule 42(b) on 'request for quotations' requires a minimum of how many quotations, and from which category of firms?

Two quotations from any registered firms
Three quotations from GST registered firms, original equipment manufacturers or authorized dealers✔️
Four quotations from SECP registered companies
Three quotations from any suppliers regardless of registration

Correct Answer Logic:

Rule 42(b)(i) and (iii) together require that at least three quotations be obtained from GST registered firms, original equipment manufacturers, or authorized dealers when procurement value exceeds PKR 100,000 but does not exceed PKR 500,000.

Chemistry QUESTION #7511

Question 7006

3.12 g of oxygen is adsorbed on 1.2 g of platinum metal. Find the volume of oxygen adsorbed per gram of the adsorbent at 1 atm and 300 K.
$[R = 0.0821\ \text{L atm K}^{-1}\ \text{mol}^{-1}]$

2.00 L/g✔️
4.00 L/g
1.60 L/g
2.40 L/g

Correct Answer Logic:

Molar mass of O$_2 = 32\ \text{g/mol}$. Moles of O$_2 = \dfrac{3.12}{32} = 0.0975\ \text{mol}$

Total volume at 1 atm, 300 K: $V = \dfrac{nRT}{P} = \dfrac{0.0975 \times 0.0821 \times 300}{1} \approx 2.40\ \text{L}$

Volume per gram of adsorbent (Pt) $= \dfrac{2.40}{1.2} = \mathbf{2.00}\ \text{L g}^{-1}$

Question 7007

If $x + \frac{1}{x} = 15$, then the value of $x^2 + \frac{1}{x^2}$ is:

$225$
$223$✔️
$17$
None of these

Correct Answer Logic:

To find $x^2 + \frac{1}{x^2}$, we square the given equation: $\left(x + \frac{1}{x}\right)^2 = 15^2$. Expanding: $x^2 + 2 \cdot x \cdot \frac{1}{x} + \frac{1}{x^2} = 225$. This simplifies to $x^2 + 2 + \frac{1}{x^2} = 225$. Therefore, $x^2 + \frac{1}{x^2} = 225 - 2 = 223$.

Dairy Food Science and Technology QUESTION #5875

Question 7008

Which packaging system is used for UHT milk to maintain commercial sterility?

HDPE bottles under vacuum
Aseptic multilayer cartons (Tetra Pak) with polyethylene/aluminum foil/paperboard✔️
Glass bottles sealed with metal caps
LDPE pouches with nitrogen flushing

Correct Answer Logic:

UHT milk requires aseptic packaging — Tetra Pak multilayer cartons are filled under sterile conditions to prevent recontamination and allow ambient storage for months.

Physics QUESTION #7041

Question 7009

The force between two atoms is $F = \alpha \beta \exp \left( -\frac{x^2}{\alpha k T} \right)$, where $x$ is distance, $k$ is Boltzmann constant, and $T$ is temperature. Find the dimensions of $\beta$.

$M^0 L^2 T^{-4}$
$M^2 L T^{-4}$✔️
$M L T^{-2}$
$M^2 L^2 T^{-2}$

Correct Answer Logic:

The exponent must be dimensionless. Thus, $[\alpha] = \frac{[x^2]}{[kT]}$.

Since $[kT]$ has dimensions of energy $[ML^2T^{-2}]$, $[\alpha] = \frac{[L^2]}{[ML^2T^{-2}]} = [M^{-1}T^2]$.

Force $F$ has the same dimensions as $\alpha\beta$.

$[\beta] = \frac{[F]}{[\alpha]} = \frac{[MLT^{-2}]}{[M^{-1}T^2]} = [M^2 L T^{-4}]$.

Nursing QUESTION #9197

Question 7011

In Jean Watson's Theory of Human Caring, the core concept originally called 'carative factors' was later renamed to:

Core conditions of caring
Transpersonal caring moments
Caritas processes✔️
Clinical caring competencies

Correct Answer Logic:

Correct Answer: C — Caritas Processes

Jean Watson originally described 10 carative factors in her 1979 theory. In her later evolution of the theory (Caring Science), she renamed them Caritas Processes (from the Latin caritas, meaning love/charity).

Key concepts in Watson's theory:

Transpersonal Caring Relationship: A special kind of human connection that transcends the physical
Caring Occasion/Moment: A moment when nurse and patient come together — each with their own phenomenal field
Caritas Processes: 10 processes guiding caring practice, emphasizing love, faith, hope, and sensitivity

Watson's theory is classified as a philosophy and science of caring, and it emphasizes the spiritual and humanistic dimensions of nursing.

Physics QUESTION #999

Question 7012

The maximum percentage error in the measurement of density of a wire is: [mass $= (0.60\pm0.003)\ \text{g}$, radius $= (0.50\pm0.01)\ \text{cm}$, length $= (10.00\pm0.05)\ \text{cm}$]

8
5✔️
4
7

Correct Answer Logic:

Density $\rho = \frac{m}{\pi r^2 l}$. $\frac{\Delta\rho}{\rho} = \frac{\Delta m}{m} + 2\frac{\Delta r}{r} + \frac{\Delta l}{l} = \frac{0.003}{0.60}+2\times\frac{0.01}{0.50}+\frac{0.05}{10.00} = 0.005+0.04+0.005 = 0.05 = 5\%$.
