Urdu QUESTION #1405

اہلِ زبان کی مخصوص بول چال میں جب لفظ اپنے حقیقی معنوں میں استعمال ہوں تو قواعد کی رو سے اسے کیا کہلاتے ہیں؟

مصدر
فعل
محاورہ
روزمرہ✔️

Correct Answer Logic:

روزمرہ وہ الفاظ، تراکیب یا جملے ہیں جو اہلِ زبان اپنی عام بول چال میں حقیقی یا مستعمل معنوں میں روزانہ استعمال کرتے ہیں۔ محاورہ اس سے مختلف ہے — محاورے میں الفاظ اپنے لغوی معنوں میں نہیں بلکہ مجازی معنوں میں استعمال ہوتے ہیں۔

Question 3

For two equal positive charges, the electric field is weakest:

Midway between them✔️
Along the perpendicular bisector
Close to either charge
At infinity

Correct Answer Logic:

At the midpoint between two equal positive charges, the electric fields due to each charge are equal in magnitude but opposite in direction, so they cancel out. The resultant electric field is zero (weakest) at this point.

Verbal Reasoning QUESTION #8096

Question 7

Compare the two quantities below.

Column A: The number of months in 7 years

Column B: The number of days in 12 weeks

Column A is greater
Column B is greater
The two quantities are equal✔️
The relationship cannot be determined from the information given

Correct Answer Logic:

Column A: $7 \text{ years} \times 12 \text{ months/year} = 84$ months.

Column B: $12 \text{ weeks} \times 7 \text{ days/week} = 84$ days.

Both quantities equal 84, so the two quantities are equal.

Boilers Mechanical Engineering QUESTION #2514

Question 9

For a beam under pure bending, the assumption that plane sections remain plane (Euler-Bernoulli hypothesis) implies that:

Shear strain across the section is constant
Normal strain varies linearly with distance from the neutral axis✔️
Shear stress is zero everywhere
Normal stress is uniform across the cross-section

Correct Answer Logic:

The Euler-Bernoulli hypothesis leads directly to a linear strain distribution: $\varepsilon = -y/\rho$, where $y$ is distance from the neutral axis and $\rho$ is the radius of curvature. This produces the linear bending stress distribution $\sigma = -My/I$.

Physics QUESTION #1041

Question 11

De-Broglie wavelength of an electron in $n=2$ state of hydrogen atom is close to (Bohr radius $= 0.052\ \text{nm}$):

1.67 nm
2.67 nm
0.067 nm
0.67 nm✔️

Correct Answer Logic:

In Bohr model: $2\pi r_n = n\lambda$. For $n=2$: $r_2 = 4r_0 = 4\times0.052 = 0.208\ \text{nm}$. $\lambda = \frac{2\pi r_2}{2} = \pi r_2 = \pi\times0.208\times10^{-9}\approx0.653\ \text{nm}\approx0.67\ \text{nm}$.

Nursing QUESTION #9139

Question 12

A woman who is 36 hours postpartum is breastfeeding. She complains of intense, painful uterine contractions during feeding. The nurse's BEST explanation is:

This is abnormal and indicates retained placental tissue
Oxytocin released during suckling causes uterine contractions (after-pains), which are normal and promote involution✔️
She has developed endometritis requiring antibiotics
The contractions indicate onset of secondary PPH

Correct Answer Logic:

After-pains (Afterbirth Pains) are cramping uterine contractions experienced after delivery:

Mechanism: During breastfeeding, infant suckling stimulates posterior pituitary to release oxytocin (Ferguson reflex). Oxytocin acts on uterine myometrium → contractions → promotes uterine involution.

\[\text{Suckling} \rightarrow \text{Posterior pituitary} \rightarrow \text{Oxytocin release} \rightarrow \text{Uterine contraction}\]

Key facts:

More intense in multiparae (uterine muscle more stretched, needs stronger contractions)
More noticeable during first few days postpartum
Normal duration: $2{-}7\,\text{days}$ postpartum
Management: reassurance, NSAIDs (ibuprofen) if severe (compatible with breastfeeding), warm compress

Uterine involution:

Immediately after delivery: fundus at umbilicus
Day 1: $1\,\text{cm}$ above umbilicus
Descends $1{-}2\,\text{cm/day}$
By day 10: not palpable abdominally
Returns to pre-pregnancy size by $6\,\text{weeks}$

Bio-Technology QUESTION #10626

Question 14

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.

Physics QUESTION #7032

Question 15

A harmonic wave is defined by the equation $y(x,t) = 10^{-3} \sin(50t + 2x)$, where variables are in SI units. Which statement regarding this wave is accurate?

The wave moves in the negative x-direction at $25\text{ ms}^{-1}$✔️
The wave moves in the positive x-direction at $100\text{ ms}^{-1}$
The wave moves in the positive x-direction at $25\text{ ms}^{-1}$
The wave moves in the negative x-direction at $100\text{ ms}^{-1}$

Correct Answer Logic:

The general form is $y = A \sin(\omega t + k x)$. Since the sign between $\omega t$ and $kx$ is positive, the wave travels in the negative x-direction. Velocity $v = \frac{\omega}{k} = \frac{50}{2} = 25\text{ ms}^{-1}$.

Chemistry QUESTION #4347

Question 18

Which of the following best explains why phenol reacts with aqueous $NaOH$, but alcohols do not?

Phenol has a lower boiling point than alcohol
Alcohols contain a strong O-H bond that cannot be broken by weak bases
Phenol forms hydrogen bonding that facilitates ionization
Phenol is weakly acidic due to resonance stabilization of phenoxide ion✔️

Correct Answer Logic:

Phenol ($C_6H_5OH$) is acidic ($pK_a \approx 10$) because the phenoxide ion ($C_6H_5O^-$) is stabilized by resonance with the benzene ring. Alcohols are not acidic enough to react with $NaOH$.

Accounting & Finance QUESTION #6081

Question 19

A firm maintains an allowance for doubtful debts at 5% of trade receivables. This year, trade receivables were $8,000, which represented a 20% decrease from the previous year. How will this change affect the current year's profit?

Decrease by $100
Decrease by $400
Increase by $100✔️
Increase by $400

Correct Answer Logic:

1. Current Receivables = $8,000. Current Allowance = $8,000 $\times$ 5% = $400.
2. Last Year Receivables = $8,000 / 0.80 = $10,000. Last Year Allowance = $10,000 $\times$ 5% = $500.
3. Change = $500 - $400 = $100 reduction in allowance.
A reduction in allowance is credited to the income statement, thus increasing profit by $100.
