Physics QUESTION #989

Question 10166

An electron projected perpendicular to a uniform magnetic field $B$ moves in a circle. If Bohr's quantization is applicable, then the radius of the electronic orbit in the first excited state is:

$\sqrt{\dfrac{h}{\pi eB}}$✔️
$\sqrt{\dfrac{2h}{\pi eB}}$
$\sqrt{\dfrac{h}{2\pi eB}}$
$\sqrt{\dfrac{4h}{\pi eB}}$

Correct Answer Logic:

By Bohr quantization: $mvr = \frac{nh}{2\pi}$. For circular motion in $B$: $mv = eBr$. So $eBr^2 = \frac{nh}{2\pi} \Rightarrow r = \sqrt{\frac{nh}{2\pi eB}}$. First excited state: $n=2$ gives $r=\sqrt{\frac{2h}{2\pi eB}}=\sqrt{\frac{h}{\pi eB}}$.

Disaster Management QUESTION #6520

Question 10168

In designing an Early Warning System for glacial lake outburst floods (GLOFs), which component represents the weakest link if neglected?

Satellite monitoring technology
Last-mile communication to remote communities✔️
Meteorological forecasting models
Data storage infrastructure

Correct Answer Logic:

While all components are important, Section 7.1 emphasizes that early warnings are only effective if they reach at-risk populations in accessible formats. For GLOFs in northern Pakistan, remote communities face communication challenges, making last-mile dissemination critical despite advanced detection capabilities.

Physics QUESTION #1179

Question 10169

Gauss's law is applicable to charges which are:

Closely distributed in space
Sparsely distributed in space
Enclosed by a broken surface
Enclosed by a closed surface✔️

Correct Answer Logic:

Gauss's law states that the total electric flux through a closed (Gaussian) surface is proportional to the total charge enclosed: $\oint \vec{E} \cdot d\vec{A} = \frac{Q_{\text{enc}}}{\varepsilon_0}$. The surface must be a closed surface — it cannot be a broken or open surface. The distribution of charges (close or sparse) does not affect the applicability of the law.

The operator leaves the shift
Chemicals, solids, or water enter the steam line from the drum✔️
The boiler is moved to another site
The fuel tank is full

Correct Answer Logic:

Carryover can lead to scaling in superheaters and damage to turbine blades.

Administration QUESTION #9568

Question 10171

McClelland's research on achievement motivation identified a correlation between high achievement needs and occupational success. A public manager with high nCh (need for achievement) is assigned to a highly routine regulatory role with fixed procedures and no discretion. According to McClelland's framework, what is the likely organizational outcome?

The manager will apply their achievement drive to improve the efficiency of procedures within existing constraints
The manager will be demotivated because high achievers require challenging work, autonomy and frequent feedback — a misalignment between individual needs and job design✔️
The manager will transition toward high nPow (need for power) as an alternative outlet for their motivational drive
The manager will exhibit Theory Y behavior regardless of job design, as intrinsic motivation overrides situational constraints

Correct Answer Logic:

McClelland found that employees with high achievement needs are most motivated by challenging, autonomy-rich work with clear feedback on performance. A routine regulatory role with fixed procedures satisfies none of these conditions. The misalignment between the individual's dominant need and job characteristics produces demotivation, reduced performance and likely turnover — demonstrating why person-job matching is a critical HRM function.

Mathematics QUESTION #1331

Question 10174

For the center of mass of a surface of revolution generated by rotating a curve about the $x$-axis, the $x$-coordinate of the center of mass is given by:

$\bar{x}=\dfrac{\int x\,dS}{\int dS}$ where $dS$ is the surface area element✔️
$\bar{x}=\dfrac{\int x\,dV}{\int dV}$
$\bar{x}=\dfrac{\int x\,dA}{\int dA}$ (area)
$\bar{x}=\dfrac{\int x\,ds}{\int ds}$ (arc length only)

Correct Answer Logic:

For a uniform surface of revolution, the center of mass lies on the axis of revolution. The $x$-coordinate is $\bar{x}=\dfrac{\int x\,dS}{\int dS}$ where $dS=2\pi y\,ds$ is the element of surface area (Pappus's theorem setup). Integration is along the generating curve.

Bio-Technology QUESTION #10626

Question 10176

In the context of protein purification, the 'purification fold' after a specific step is calculated as:

$\text{Purification fold} = \dfrac{\text{Total protein after step}}{\text{Total protein before step}}$
$\text{Purification fold} = \dfrac{\text{Specific activity after step}}{\text{Specific activity before step}}$✔️
$\text{Purification fold} = \dfrac{\text{Yield after step}}{\text{Yield before step}} \times 100\%$
$\text{Purification fold} = \dfrac{\text{Total units after step}}{\text{Total units before step}}$

Correct Answer Logic:

Purification fold $= \dfrac{\text{Specific activity after step (units/mg protein)}}{\text{Specific activity at start (units/mg protein)}}$. Specific activity = total enzyme units / total protein. As purification proceeds, total protein decreases while enzyme units are (ideally) maintained, so specific activity increases. A high purification fold indicates effective removal of contaminating proteins. It is tracked alongside yield (% recovery of enzyme units) in a purification table.

Education QUESTION #10882

Question 10179

A teacher's attention to selecting appropriate learning materials and teaching techniques is aimed at meeting:

Social needs
Learner needs✔️
Educational needs
Cultural needs

Correct Answer Logic:

Teachers select materials and techniques primarily to meet learner needs — the individual academic, developmental, cognitive, emotional, and motivational requirements of each student. Effective teaching is learner-centred: materials and methods must match learners' prior knowledge, learning styles, readiness levels, and interests. While social, cultural, and educational needs are broader considerations, the immediate focus of instructional decisions is always the specific needs of the learners in the classroom.
