Administration QUESTION #9595

Question 6

A Work Cell layout clusters dissimilar machines into a 'cell' that completes an entire family of parts. Compared to a process layout, which specific performance improvement does a work cell most directly achieve?

Higher machine utilization rates — because work cells consolidate all machines in one area, reducing idle time across the plant
Reduced setup time, lower work-in-process inventory, faster throughput and simpler scheduling — because related parts move through a dedicated cell without travelling across the plant to different functional departments✔️
Greater product variety — because work cells can be reconfigured more quickly than functional departments
Elimination of quality defects — because cellular manufacturing assigns quality responsibility to a team rather than distributing it across functional departments

Correct Answer Logic:

Work cells (cellular manufacturing) achieve lean production benefits by: (1) grouping machines that process a part family into one cell, (2) eliminating inter-department travel and queuing, (3) reducing WIP inventory, (4) simplifying scheduling to within-cell routing, and (5) reducing setup times through part family similarity. Machine utilization may actually be lower (cells have dedicated machines that may idle), but throughput time and WIP improvements are the primary benefits.

MBBS QUESTION #10286

Question 7

A patient with polyuria and polydipsia fails to concentrate urine during a water deprivation test but responds appropriately (urine osmolality rises) after administration of exogenous desmopressin (an ADH analogue). This pattern is most consistent with:

Central (neurogenic) diabetes insipidus✔️
Nephrogenic diabetes insipidus
Primary polydipsia
Uncontrolled diabetes mellitus

Correct Answer Logic:

Central diabetes insipidus results from inadequate hypothalamic-pituitary ADH secretion; because the renal collecting duct receptors are intact, administering exogenous ADH (desmopressin) restores urine concentrating ability — in contrast to nephrogenic DI, where renal resistance to ADH means desmopressin produces little or no response.

Accounting & Finance QUESTION #6052

Question 8

Which one of the following qualifies as a capital expenditure?

Paying for renovations that upgrade and improve a building✔️
Paying carriage-outward charges related to delivering sold goods
Paying legal fees to recover outstanding amounts from customers
Paying performance bonuses to production workers

Correct Answer Logic:

Capital expenditure is spending that improves, extends the life of, or adds value to a long-term asset. Renovating and upgrading a building increases its value and useful life — this is capital expenditure. The other options are all revenue expenditures: carriage outwards, legal recovery fees, and wage bonuses are period costs that appear on the income statement and do not create lasting assets.

Aptitude QUESTION #10987

Question 9

A right circular cone of base radius $r$ and height $h$ is placed inside a hollow hemisphere of radius $R$ such that the cone's base coincides with the hemisphere's base circle and its apex touches the hemisphere's inner surface. If $r = \frac{R}{2}$, what is the ratio $\frac{h}{R}$?

$\frac{\sqrt{3}}{2}$✔️
$\frac{\sqrt{2}}{2}$
$\frac{\sqrt{3}}{4}$
$\frac{1}{2}$

Correct Answer Logic:

The hemisphere's center is at the base center. The apex is at distance $R$ from center. Using Pythagoras: $h^2 + r^2 = R^2$. With $r = R/2$, we get $h^2 = R^2 - R^2/4 = 3R^2/4$, so $h = \frac{\sqrt{3}R}{2}$. Thus $\frac{h}{R} = \frac{\sqrt{3}}{2}$.

Question 10

To express 2.08 in terms of percentage, one gets:

$208\%$✔️
$20\%$
$20.8\%$
None of these

Correct Answer Logic:

To convert a decimal to percentage, multiply by 100. Therefore, $2.08 \times 100 = 208\%$. This means 2.08 is equivalent to 208 percent.

Question 12

Carnivorous plants digest small animals primarily to obtain which nutrient?

Carbohydrates
Lipids
Nitrites✔️
Water

Correct Answer Logic:

Carnivorous plants (e.g., Venus flytrap, pitcher plant) grow in nitrogen-poor soils. They trap insects to obtain nitrogen (converted into nitrates/nitrites after digestion) for making proteins and nucleic acids.

Question 13

Simplify $\frac{12}{18}$ to lowest terms:

$\frac{6}{9}$
$\frac{4}{6}$
$\frac{2}{3}$✔️
$\frac{1}{2}$

Correct Answer Logic:

GCD of $12$ and $18$ is $6$. So $\frac{12}{18} = \frac{12 \div 6}{18 \div 6} = \frac{2}{3}$

Library Sciences QUESTION #1577

Question 14

Which preservation technique involves creating a digital surrogate of a rare or fragile physical item to reduce handling of the original while ensuring long-term access?

Lamination
Fumigation
Digitization✔️
Microfilming

Correct Answer Logic:

Digitization converts rare, fragile, or unique physical items (manuscripts, maps, photographs) into digital surrogates, allowing users to access the content without handling the original — thereby reducing physical wear, environmental exposure, and the risk of damage while ensuring broad and persistent access.

Boilers Mechanical Engineering QUESTION #2454

Question 15

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 $T_{max}=V_{max}$: $\omega_n^2=k/m$.

Chemistry QUESTION #7508

Question 17

0.5 moles of gas A and $x$ moles of gas B together exert a pressure of 200 Pa in a 10 m$^3$ container at 1000 K. Given that $R$ is the gas constant in J K$^{-1}$ mol$^{-1}$, the value of $x$ is:

$\dfrac{2R}{4+R}$
$\dfrac{2R}{4-R}$
$\dfrac{4+R}{2R}$
$\dfrac{4-R}{2R}$✔️

Correct Answer Logic:

Apply the ideal gas law: $PV = n_{\text{total}}RT$

$n_{\text{total}} = 0.5 + x$

$200 \times 10 = (0.5 + x) \times R \times 1000$

$2000 = 1000R(0.5 + x)$

$2 = R(0.5 + x) = 0.5R + Rx$

$Rx = 2 - 0.5R$

$x = \dfrac{2 - 0.5R}{R} = \dfrac{4 - R}{2R}$
