Accounting & Finance QUESTION #6112

Jaime's data: Capital start $14,000; Capital end $12,300; Loan received $4,000; Cash drawings $17,200; Private phone charges paid by business $300. What was the profit for the year?

$11,800
$15,500
$15,800✔️
$19,200

Correct Answer Logic:

Option C ($15,800) is correct.

Total drawings = Cash drawings $17,200 + Private phone $300 = $17,500

The loan is a liability, not capital introduced.

Profit = Closing capital + Drawings − Opening capital = $12,300 + $17,500 − $14,000 = $15,800

Boilers Mechanical Engineering QUESTION #2483

Question 2

The velocity of a node B of a driver link in rotational motion (angular velocity $\omega = \dot{\phi}$, link length $L_{AB}$) is given by:

$v_{Bx} = -L_{AB}\dot{\phi}\sin\phi,\quad v_{By} = L_{AB}\dot{\phi}\cos\phi$✔️
$v_{Bx} = L_{AB}\dot{\phi}\cos\phi,\quad v_{By} = L_{AB}\dot{\phi}\sin\phi$
$v_{Bx} = L_{AB}\dot{\phi}^2\cos\phi,\quad v_{By} = -L_{AB}\dot{\phi}^2\sin\phi$
$v_{Bx} = -L_{AB}\ddot{\phi}\cos\phi,\quad v_{By} = L_{AB}\ddot{\phi}\sin\phi$

Correct Answer Logic:

Differentiating position equations $x_B=x_A+L_{AB}\cos\phi$ and $y_B=y_A+L_{AB}\sin\phi$ with respect to time: $v_{Bx}=-L_{AB}\dot{\phi}\sin\phi$ and $v_{By}=L_{AB}\dot{\phi}\cos\phi$.

Chemistry QUESTION #5556

Question 5

In the photosynthesis process, how many ATP molecules are consumed in the synthesis of each glucose molecule?

18 ATP✔️
10 ATP
8 ATP
6 ATP

Correct Answer Logic:

The Calvin cycle (dark reactions) requires 18 ATP and 12 NADPH to fix 6 molecules of $CO_2$ into one glucose molecule: $6CO_2 + 18ATP + 12NADPH \to C_6H_{12}O_6 + 18ADP + 12NADP^+$. Each turn of the cycle uses 3 ATP and 2 NADPH; 6 turns are needed for one glucose.

Question 7

In $\mathbb{Z}_{18}$, what is the order of the cyclic subgroup generated by element $6$?

$2$
$3$✔️
$6$
$9$

Correct Answer Logic:

Order of $\langle 6 \rangle = \frac{18}{\gcd(6,18)} = \frac{18}{6} = 3$.

Nursing QUESTION #9310

Question 8

A post-operative patient complains of sudden severe chest pain and shortness of breath on day 3. SpO₂ drops to 88%. Which is the nurse's first priority action?

Administer prescribed analgesic for pain
Perform a 12-lead ECG
Sit the patient upright and administer oxygen✔️
Call the physician and wait for orders

Correct Answer Logic:

Using the ABC (Airway, Breathing, Circulation) framework — the immediate first action is to address oxygenation:

Sit patient upright (High Fowler's) — maximizes lung expansion
Administer supplemental oxygen — target SpO₂ ≥ 94%
Call for help / activate rapid response team
12-lead ECG (to differentiate PE vs MI)
Establish IV access
Prepare for further investigations (D-dimer, CT pulmonary angiography for PE)

This presentation on day 3 post-surgery is classic for Pulmonary Embolism (PE) — the peak incidence is 2–7 days post-operatively. Hypoxia is life-threatening and must be corrected before diagnostic workup. A nurse who waits for physician orders before applying oxygen is delaying potentially life-saving treatment.

Question 9

Choose the sentence with the correct tense and sentence structure:

He is going to the market yesterday.
I had been waiting for the bus and it arrives.
She will finish her homework before she went to bed.
They were playing football when it started to rain.✔️

Correct Answer Logic:

Option D correctly uses past continuous ('were playing') for an ongoing action interrupted by another past action ('started to rain' - simple past). The other options mix tenses incorrectly.

Planning QUESTION #4997

Question 10

What does 'primate city' phenomenon indicate in urban systems?

Equal distribution of city sizes
Dominance of one disproportionately large city✔️
Multiple cities of similar size
Declining urban population

Correct Answer Logic:

A primate city is disproportionately larger (typically 2+ times) than the second-largest city, dominating the urban system economically and politically. Common in developing countries, it often indicates centralized development and regional imbalances.

Quantitative Reasoning QUESTION #66

Question 11

For decades, economists believed that increased productivity would naturally lead to higher wages. However, recent studies indicate that while productivity has surged, wage growth has stagnated, suggesting that other structural factors — such as labor market policies, globalization, and technological automation — may be influencing income distribution.

Sub-Questions:

Question 1

Which of the following best expresses the main idea of the passage?

A) Productivity and wage growth are always directly proportional.
B) Wage stagnation is primarily caused by technological advancements.
C) Increased productivity no longer guarantees higher wages due to other influencing factors.✔️
D) Globalization is the sole reason for unequal income distribution.

Question 2

What does surged meaning in this paragraph?

Soar
Sudden✔️
Inclined
Unexpected

Correct Answer Logic:

The passage emphasizes that higher productivity no longer ensures wage increases because of other structural factors — exactly what option C states.

Psychology QUESTION #9821

Question 13

Sources of frustration include:

Environmental lacks
Environmental obstacles
Incompatible motives
All of the above✔️

Correct Answer Logic:

Frustration arises from all three sources: environmental lacks (absent resources), environmental obstacles (barriers to goals), and incompatible motives (approach-avoidance conflicts where competing goals cannot both be satisfied).

Question 14

If $a : b = 3 : 4$ and $b : c = 6 : 7$, find $a : b : c$.

9:12:14✔️
3:04:07
6:08:07
3:06:07

Correct Answer Logic:

$a:b = 3:4$ and $b:c = 6:7$. Make $b$ common: $b = \text{LCM}(4,6) = 12$. $a:b = 9:12$ and $b:c = 12:14$. So $a:b:c = 9:12:14$.

Physics QUESTION #1165

Question 16

At constant pressure and volume, the exact relation between $C_p$ and $C_v$ is:

C_p > C_v
$C_p / C_v > 1$
$C_p - C_v = R$
All of these✔️

Correct Answer Logic:

All three relations are simultaneously true for an ideal gas: (A) $C_p > C_v$ because at constant pressure extra heat is needed to do work against expansion. (B) $C_p/C_v = \gamma > 1$. (C) The Mayer relation: $C_p - C_v = R$ (per mole). So all of these are correct.

Dairy Food Science and Technology QUESTION #5989

Question 17

Sodium hexametaphosphate and trisodium citrate are used as emulsifying salts in processed cheese. Their mechanism involves:

Acting as antimicrobial agents preventing mold growth
Chelating $\text{Ca}^{2+}$ from the casein-calcium phosphate complex, solubilizing and dispersing casein proteins to form a stable protein-fat emulsion upon heating ('creaming of casein')✔️
Lowering the $\text{pH}$ to improve acid-gel formation
Crosslinking casein proteins through phosphate bridges

Correct Answer Logic:

Emulsifying salts in processed cheese work via $\text{Ca}^{2+}$ chelation (sequestration). By removing $\text{Ca}^{2+}$ from casein-calcium-phosphate linkages, they break down the protein matrix, allowing individual casein molecules to hydrate, unfold, and interact with fat at the interface during heating ('creaming of casein').
