Physics QUESTION #1022

Question 2

A parallel plate capacitor made of circular plates is being charged such that the surface charge density on its plates is increasing at a constant rate with time. The magnetic field arising due to displacement current is:

Non-zero everywhere with maximum at the imaginary cylindrical surface connecting peripheries of the plates✔️
Zero between the plates and non-zero outside
Zero at all places
Constant between the plates and zero outside the plates

Correct Answer Logic:

By Ampere-Maxwell law, the displacement current $I_d = \varepsilon_0 \frac{d\Phi_E}{dt}$ creates a magnetic field. Inside the capacitor, $B \propto r$ (increases with radius), and is maximum at the rim of the plates. Outside the rim, $B \propto 1/r$. So B is non-zero everywhere with maximum at the cylindrical surface connecting plate peripheries.

Dairy Food Science and Technology QUESTION #5891

Question 3

The water activity $(a_w)$ of whole milk powder is maintained below which value to ensure microbiological safety and prevent caking?

$a_w = 0.95$
$a_w = 0.85$
$a_w = 0.60$✔️
$a_w = 0.30$

Correct Answer Logic:

Whole milk powder should have $a_w < 0.60$ (typically $0.1\text{–}0.3$) to prevent microbial growth (most bacteria require $a_w > 0.90$) and enzymatic reactions. Moisture content is kept below $3\text{–}4\%$.

Geography QUESTION #1247

Question 4

The process involved in Himalayan orogeny is:

Volcanism
Plate convergence✔️
Plate divergence
None of these

Correct Answer Logic:

The Himalayan mountain range was formed by the convergence (collision) of the Indian Plate and the Eurasian Plate, which began approximately 50 million years ago. As the Indian subcontinent moved northward and collided with Eurasia, the intervening Tethys Sea sediments were folded and uplifted to form the Himalayas. This is a classic example of continent-continent collision.

Accounting & Finance QUESTION #6051

Question 6

A business records a credit sale of Rs. 350 (no cash involved) using accrual accounting. How will this transaction be reflected in the financial statements?

Rs. 350 would appear on the balance sheet as a sale
Rs. 350 would appear on the income statement as a sale✔️
Rs. 350 would appear on the statement of cash flows as a cash outflow
The transaction would not be reported since no cash was exchanged

Correct Answer Logic:

Under accrual accounting, revenue is recognized when it is earned, not when cash is received. A credit sale of Rs. 350 means the business has earned the revenue, so it is recorded in the income statement as sales revenue. The receivable (Rs. 350) is recorded on the balance sheet as an asset, but the sale itself appears on the income statement. Cash-basis accounting would delay recognition until cash is received, but accrual accounting does not.

Question 7

Which technique is most effective for reducing urban heat island effect?

Increasing building density
Expanding asphalt surfaces
Green infrastructure and tree planting✔️
Removing vegetation

Correct Answer Logic:

Green infrastructure (green roofs, urban forests, parks) reduces urban heat island effect through evapotranspiration, shading, and lower surface temperatures compared to concrete and asphalt.

Math Physics Chemistry Biology QUESTION #7784

Question 9

Depolarization of the postsynaptic membrane is caused by diffusion of which ion?

Calcium ions
Chloride ions
Potassium ions
Sodium ions✔️

Correct Answer Logic:

Depolarization occurs when Na⁺ enters the postsynaptic neuron (excitatory postsynaptic potential). Cl⁻ influx causes hyperpolarization (inhibitory). Ca²⁺ triggers neurotransmitter release, not directly depolarization.

General Knowledge QUESTION #11537

Question 10

Identify the odd one out among the options below:

Operating System✔️
Interpreter
Compiler
Assembler

Correct Answer Logic:

The Operating System is the odd one out. Interpreter, Compiler, and Assembler are all language translators — they convert source code into another language (machine code). An Operating System is system software that manages hardware resources and provides services to applications, not a language translator.

Question 11

According to Dilling's rule, the child's dose is calculated as:

$D_{A} \times \frac{Age}{20}$✔️
$D_{A} \times \frac{Age}{Age+12}$
$D_{A} \times \frac{Weight \text{ (lb)}}{150}$
$D_{A} \times \frac{Age}{24}$

Correct Answer Logic:

Dilling's rule: $\text{Child dose} = (\text{Age}/20) \times \text{Adult dose}$.

Question 14

What does the phrase 'ONCE IN A BLUE MOON' mean? (Note: An idiom's meaning cannot be guessed from the individual words)

Very frequently
Every month
Very rarely✔️
During nighttime

Correct Answer Logic:

'Once in a blue moon' is an idiom meaning something that happens very rarely or infrequently. A 'blue moon' is a rare astronomical event, which is why it represents rarity. Example: 'He visits us once in a blue moon.'

Accounting & Finance QUESTION #9623

Question 18

A vehicle repair costing Rs. 5,000 was incorrectly debited to the Vehicle Asset Account instead of the Repairs Expense Account. The rectification entry is:

Debit: Vehicle Asset Rs. 5,000; Credit: Repairs Expense Rs. 5,000
Debit: Repairs Expense Rs. 5,000; Credit: Vehicle Asset Rs. 5,000✔️
Debit: Cash Rs. 5,000; Credit: Repairs Expense Rs. 5,000
Debit: Repairs Expense Rs. 10,000; Credit: Vehicle Asset Rs. 5,000; Credit: Cash Rs. 5,000

Correct Answer Logic:

The correct entry should have been Dr. Repairs Expense / Cr. Cash. The incorrect entry posted was Dr. Vehicle Asset / Cr. Cash. The credit was correct; only the debit needs correction. To rectify: remove the incorrect debit from Vehicle Asset (Cr. Vehicle Asset Rs. 5,000) and give the correct debit to Repairs Expense (Dr. Repairs Expense Rs. 5,000).

Mathematics QUESTION #7467

Question 19

If sum of all the solutions of the equation $8\cos x \cdot (\cos(\frac{\pi}{6}+x) \cdot \cos(\frac{\pi}{6}-x) - \frac{1}{2}) = 1$ in [0, π] is kπ, then k is equal to:

$\frac{8}{9}$
$\frac{20}{9}$
$\frac{2}{3}$
$\frac{13}{9}$✔️

Correct Answer Logic:

Simplifying the product: $\cos(\frac{\pi}{6}+x)\cos(\frac{\pi}{6}-x) = \frac{1}{2}[\cos(\frac{\pi}{3}) + \cos(2x)] = \frac{1}{2}[\frac{1}{2} + \cos 2x] = \frac{1}{4} + \frac{\cos 2x}{2}$. The equation becomes: $8\cos x(\frac{1}{4} + \frac{\cos 2x}{2} - \frac{1}{2}) = 1$, which gives $8\cos x(\frac{\cos 2x}{2} - \frac{1}{4}) = 1$, or $4\cos x(\cos 2x - \frac{1}{2}) = 1$. Since $\cos 2x = 2\cos^2 x - 1$: $4\cos x(2\cos^2 x - 1 - \frac{1}{2}) = 1$, giving $4\cos x(2\cos^2 x - \frac{3}{2}) = 1$, or $8\cos^3 x - 6\cos x - 1 = 0$. Solving this cubic and finding solutions in [0,π], then summing them gives $k = \frac{2}{3}$.

Correct Answer Logic:

An algorithm is a series of steps that solves specific problems. A step-by-step checklist for processing invoices is exactly analogous — it provides ordered instructions to reach a defined outcome, just as an algorithm does in computing.
