Chemistry QUESTION #7173

Question 4887

Considering the ground state energy of a hydrogen atom is $-13.6 \text{ eV}$, what would be the energy of the second excited state for a $He^{+}$ ion in eV?

$-54.4$
$-3.4$
$-6.04$✔️
$-27.2$

Correct Answer Logic:

For hydrogen-like species, $E_{n} = -13.6 \frac{Z^{2}}{n^{2}} \text{ eV}$.

For $He^{+}$, atomic number $Z = 2$.
The second excited state corresponds to $n = 3$.
$E_{3} = -13.6 \times \frac{2^{2}}{3^{2}} = -13.6 \times \frac{4}{9}$
$E_{3} \approx -6.04 \text{ eV}$

Education QUESTION #6891

Question 4890

Effective Behavioral Support Systems (EBS) are described as 'team-based' processes. Which of the following is the MOST important structural reason for this team-based approach?

It distributes the financial cost of behavioral interventions across departments
It ensures shared ownership and a school-wide commitment to addressing the unique behavioral needs of individual students✔️
It allows teachers to avoid individual accountability for classroom management failures
It enables the school to apply for external grants for behavioral programming

Correct Answer Logic:

EBS is explicitly designed as a team-based process because behavioral issues require coordinated, school-wide commitment — not isolated teacher interventions. Shared ownership means that all stakeholders (teachers, administrators, support staff) collectively develop, implement, and monitor a behavioral support plan, making it more coherent and sustainable.

Tourism & Hospitality Management QUESTION #1613

Question 4891

The Tourism and Hospitality Laws course addresses 'the law of tort' as relevant to hospitality operations. Which of the following scenarios would most directly engage tort law in a hotel context?

A hotel failing to renew its business registration on time
A guest slipping on an unmarked wet floor in the hotel lobby and sustaining injury due to the hotel's negligence✔️
A chef preparing food that does not meet a guest's flavor preference
A hotel raising its room rates during peak season

Correct Answer Logic:

The Tourism and Hospitality Laws course covers torts — specifically negligence, trademark infringement, and fraud — in Module 2. A guest injured due to the hotel's failure to maintain safe premises (e.g., an unmarked wet floor) is a classic negligence tort scenario in which the hotel owes a duty of care and may be held liable for breach of that duty.

Verbal Reasoning QUESTION #8110

Question 4894

If the arithmetic mean of 5 consecutive integers is 12, what is the sum of the least and greatest of these integers?

$24$✔️
$14$
$12$
$11$

Correct Answer Logic:

For 5 consecutive integers, the mean equals the middle (3rd) integer. So the middle integer is 12.

The 5 integers are: $10, 11, 12, 13, 14$.

The least is 10 and the greatest is 14.

Sum $= 10 + 14 = 24$.

Math Physics Chemistry Biology QUESTION #7729

Question 4896

The anatomical features of which group show similarities during embryonic development?

All living things
All non-vertebrates
All vertebrates✔️
Human jellyfish and mouse

Correct Answer Logic:

Vertebrates (fish, amphibians, reptiles, birds, mammals) share similar embryonic stages (e.g., pharyngeal pouches, tail, and limb buds) which indicates common ancestry. This is evidence of divergent evolution.

The Constitution of Pakistan QUESTION #9385

Question 4897

Article 45 grants the President power to pardon. Which of the following statements about this power is constitutionally accurate?

The power extends only to Federal offences
The President may grant pardon even before conviction
The power applies to sentences passed by any court, tribunal or other authority✔️
Parliament can transfer this power to a court

Correct Answer Logic:

Article 45 provides: 'The President shall have power to grant pardon, reprieve and respite, and to remit, suspend or commute any sentence passed by any court, tribunal or other authority.' The scope is broad — 'any court, tribunal or other authority' — and is not limited to post-conviction stages or federal offences.

Question 4898

The Rayleigh (energy) method for approximating the fundamental natural frequency equates:

Maximum kinetic energy to maximum potential energy: $T_{max} = V_{max}$ giving $\omega_n^2 = k/m$✔️
Mean kinetic energy to mean potential energy
Damping energy to spring potential energy
Total energy to the product of mass and stiffness

Correct Answer Logic:

Rayleigh's method: for conservative systems in harmonic motion, maximum kinetic energy $T_{max}=\frac{1}{2}m(\omega_n X)^2$ equals maximum potential energy $V_{max}=\frac{1}{2}kX^2$. Setting $T_{max}=V_{max}$: $\omega_n^2=k/m$.

Physics QUESTION #7081

Question 4899

A pendulum clock loses $12\text{ s/day}$ at $40^{\circ}\text{C}$ and gains $4\text{ s/day}$ at $20^{\circ}\text{C}$. Find the temperature for correct time and the coefficient of linear expansion $\alpha$.

$60^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-4}/^{\circ}\text{C}$
$30^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-3}/^{\circ}\text{C}$
$55^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-2}/^{\circ}\text{C}$
$25^{\circ}\text{C}$, $\alpha=1.85 \times 10^{-5}/^{\circ}\text{C}$✔️

Correct Answer Logic:

The change in time is given by $\Delta t = \frac{1}{2} \alpha \Delta \theta \times t$.

$12 = \frac{1}{2} \alpha (40 - \theta) \times 86400$
$-4 = \frac{1}{2} \alpha (20 - \theta) \times 86400$
Dividing the equations gives $\theta = 25^{\circ}\text{C}$.
Substituting $\theta$ back gives $\alpha = 1.85 \times 10^{-5}/^{\circ}\text{C}$.
