Question 2

The energy of the second Bohr orbit of hydrogen atom is $-328$ kJ/mol. Based on this, the energy of the fourth Bohr orbit will be:

$-41$ kJ/mol
$-1312$ kJ/mol
$-164$ kJ/mol
$-82$ kJ/mol✔️

Correct Answer Logic:

Bohr's energy formula: $E_n = \dfrac{E_1}{n^2}$

Given $E_2 = -328$ kJ/mol, so $E_1 = -328 imes 4 = -1312$ kJ/mol.

$E_4 = \dfrac{-1312}{16} = -82$ kJ/mol

Key point: as $n$ increases, energy becomes less negative — outer orbits are less tightly bound.

CISA QUESTION #1784

Question 5

Which statement most accurately distinguishes compliance testing from substantive testing?

Compliance testing verifies the presence of controls; substantive testing examines the integrity of transaction contents✔️
Substantive testing checks for the presence of controls; compliance testing examines actual contents
Both test types are identical; the only difference is whether the entity falls under the Sarbanes-Oxley Act
Compliance testing evaluates individual account balances; substantive testing reviews written corporate policies

Correct Answer Logic:

Compliance testing determines whether required controls exist and are being applied consistently. Substantive testing goes deeper — it examines the substance and accuracy of the actual data, transactions, or account balances to verify that no material errors or misstatements are present.

Law QUESTION #9486

Question 6

A decree-holder A wishes to attach a sum of Rs. 500,000 kept in a bank account belonging to the judgment-debtor B, which was earned by B as salary and deposited over time. B argues that salary is exempt from attachment. Can the bank balance representing accumulated salary be attached?

Yes; once salary has been received and deposited in a bank account, it loses its character as salary and becomes an ordinary debt recoverable from the bank, which is attachable✔️
Yes; but only with the permission of the State Bank of Pakistan
No; bank accounts can never be attached in execution
No; salary retains its exempt character even after being deposited in a bank

Correct Answer Logic:

The exemption under Section 60(1)(i) CPC applies to salary before and until it is actually payable; once salary has been paid and deposited in a bank, it is converted into a debt due from the bank and loses its exempt character, becoming attachable in execution.

Question 7

Insects belong to which class in the phylum Arthropoda?

Hexapoda✔️
Diplopoda
Chilopoda
Arachnida

Correct Answer Logic:

Insects belong to the class Hexapoda (or Insecta), meaning 'six legs.' Defining features include: three pairs of jointed legs, three body segments (head, thorax, abdomen), one pair of antennae, and usually wings. Diplopoda = millipedes (two pairs of legs per segment); Chilopoda = centipedes (one pair per segment); Arachnida = spiders, scorpions (four pairs of legs).

Question 8

POLEMICAL: Choose the word most nearly opposite in meaning to this word.

imitative
lavish
conciliatory✔️
attractive

Correct Answer Logic:

POLEMICAL means relating to strong controversy or dispute — aggressive in argument. Its antonym is conciliatory, which means intended to make peace, reduce conflict, or bring about agreement. 'Imitative' means copying others. 'Lavish' means extravagant. 'Attractive' means pleasing. Only 'conciliatory' opposes the confrontational nature of 'polemical.'

Question 9

The degree of freedom of a 'ball-and-socket' (sphere) kinematic pair is:

$1$ DOF
$2$ DOF
$3$ DOF✔️
$6$ DOF

Correct Answer Logic:

A ball-and-socket (spherical) kinematic pair allows three independent angular rotations between the joined links — it is a 3rd-class pair (removes 3 DOF from 6, leaving 3 DOF).

Medication procedure review✔️
Surgical supplies
Retail sales of cosmetics

Correct Answer Logic:

Civil Procedure QUESTION #3704

Question 11

A plaintiff from State A sues a defendant from State B in federal court in State B for $\text{\$80,000}$ for a breach of contract. The defendant files a counterclaim against the plaintiff for $\text{\$15,000}$ arising from the same transaction. The plaintiff then realizes that the contract claim is weak and voluntarily dismisses the original complaint. The defendant wants to proceed with the counterclaim. Does the federal court have jurisdiction over the counterclaim?

No, because the original complaint was dismissed, and the counterclaim is only $\text{\$15,000}$.
No, because there is no longer a 'case or controversy' under Article III.
Yes, because the court had original jurisdiction over the complaint and the counterclaim arises from the same transaction (Rule 13(a)).✔️
Yes, but only if the plaintiff re-files the original claim.

Correct Answer Logic:

Under 28 U.S.C. $\S 1367$, a federal court has supplemental jurisdiction over compulsory counterclaims that arise from the same nucleus of operative fact. Once jurisdiction is established at the time of filing, the dismissal of the main claim does not necessarily divest the court of jurisdiction over the remaining supplemental claims.

Question 12

Which material is known as the fifth element of green building due to its thermal mass and embodied carbon benefits?

Reinforced concrete
Recycled steel
Rammed earth✔️
Structural glass

Correct Answer Logic:

Rammed earth is celebrated in sustainable/green architecture for:

Thermal mass: Absorbs heat during the day and releases it at night, moderating indoor temperatures.
Low embodied carbon: Uses local, natural soil — minimal processing, no cement required in traditional form.
Durability: Can last centuries (e.g., Great Wall of China sections).
Aesthetic: Beautiful natural striations and earth tones.

It is a vernacular material revived in contemporary eco-architecture.

MBBS QUESTION #10349

Question 17

A patient with glucose-6-phosphate dehydrogenase (G6PD) deficiency develops acute hemolytic anemia after taking an oxidant drug such as primaquine or dapsone, or after eating fava beans. This is best explained by:

Reduced NADPH production impairing regeneration of reduced glutathione, leaving red cells vulnerable to oxidative damage from free radicals and peroxides generated by the offending trigger✔️
Excess NADPH directly lysing red blood cells
A primary structural defect in the hemoglobin molecule itself
Deficient ATP production within red blood cells due to a glycolytic block

Correct Answer Logic:

G6PD deficiency reduces the red cell's capacity to regenerate NADPH (and thus reduced glutathione) via the HMP shunt, its only NADPH source, since mature red cells lack mitochondria; under oxidative stress, hemoglobin and membrane proteins are damaged, producing Heinz bodies and hemolysis, classically precipitated by oxidant drugs, infection, or fava bean ingestion.

Question 18

Dehydrohalogenation of an alkyl halide is typically carried out with:

Alcoholic KOH✔️
Aqueous KOH
Conc. H₂SO₄
Zn dust

Correct Answer Logic:

Alcoholic KOH (strong base in ethanol) promotes E2 elimination to form alkenes. Aqueous KOH favors substitution; conc. H₂SO₄ can cause elimination but also other reactions; Zn dust is for dehalogenation (vicinal dihalides).

Physics QUESTION #1177

Question 19

A photon having the same energy as an electron has wavelength __________ as electron's De Broglie wavelength.

Shorter
Longer✔️
Same
None of these

Correct Answer Logic:

For an electron: $\lambda_e = \frac{h}{\sqrt{2m_eE}}$. For a photon: $\lambda_{ph} = \frac{hc}{E}$. Ratio: $\frac{\lambda_{ph}}{\lambda_e} = \frac{hc}{E} \cdot \frac{\sqrt{2m_eE}}{h} = c\sqrt{\frac{2m_e}{E}}$. For typical energies, this ratio $\gg 1$, meaning the photon's wavelength is much longer than the electron's De Broglie wavelength at the same energy.
