Civil Engineering QUESTION #6636

In the design of one-way slabs, the principal reinforcement is designed to resist:

Shrinkage stresses
Flexural moments in the long direction
Flexural moments in the short direction✔️
Torsional moments

Correct Answer Logic:

A one-way slab transfers most of its load to the supports in the short direction; hence the main reinforcement is placed parallel to the short span.

Physics QUESTION #7332

Question 7123

A projectile is thrown at angles $(45°-\theta)$ and $(45°+\theta)$ with the horizontal. The ratio of their horizontal ranges is:

$1:1$✔️
$2:3$
$1:2$
$2:1$

Correct Answer Logic:

Using $R = \dfrac{u^2\sin2\alpha}{g}$:

$R_1 = \dfrac{u^2\sin(90°-2\theta)}{g} = \dfrac{u^2\cos2\theta}{g}$

$R_2 = \dfrac{u^2\sin(90°+2\theta)}{g} = \dfrac{u^2\cos2\theta}{g}$

$R_1 : R_2 = \mathbf{1:1}$

Statistics QUESTION #1986

Question 7124

In hypothesis testing, if the level of significance $\alpha = 0.05$ and the power of the test is $0.80$, then the probability of a Type-II error $(\beta)$ is:

$0.05$
$0.95$
$0.20$✔️
$0.80$

Correct Answer Logic:

Power $= 1 - \beta$, so $\beta = 1 - \text{Power} = 1 - 0.80 = 0.20$. Type-II error $\beta$ is the probability of failing to reject a false null hypothesis, and power is the probability of correctly rejecting it.

Physics QUESTION #7094

Question 7128

A particle moves in a circle at a constant $10\text{ ms}^{-1}$. What is the magnitude of velocity change after turning $60^{\circ}$?

$10\sqrt{3}\text{ m/s}$
zero
$10\sqrt{2}\text{ m/s}$
$10\text{ m/s}$✔️

Correct Answer Logic:

The magnitude of change in velocity is $|\Delta v| = 2v \sin(\frac{\theta}{2})$.

$|\Delta v| = 2(10) \sin(60^{\circ}/2) = 20 \sin 30^{\circ}$
$|\Delta v| = 20 \times \frac{1}{2} = 10\text{ m/s}$.

Library Sciences QUESTION #1548

Question 7130

Douglas McGregor's Theory X assumption about library employees holds that:

Employees are self-directed, creative, and seek responsibility
Employees inherently dislike work, avoid responsibility, and must be coerced and controlled to perform✔️
Employee motivation depends primarily on salary levels
Employees are motivated primarily by social relationships at work

Correct Answer Logic:

McGregor's Theory X assumes employees are inherently lazy, dislike work, and need close supervision and coercion. Theory Y, by contrast, assumes employees are self-motivated. Library managers drawing on Evans et al. (2007) are encouraged to adopt Theory Y approaches to foster professional growth and staff engagement.

Nursing QUESTION #9246

Question 7132

A patient in the ICU is started on Propofol infusion for sedation at $50 \text{ mcg/kg/min}$. After 48 hours, the patient develops metabolic acidosis, elevated triglycerides, elevated CK, and kidney failure. What is the MOST likely complication?

Propofol-induced hepatotoxicity
Propofol Infusion Syndrome (PRIS)✔️
Opioid-induced hyperalgesia
Benzodiazepine withdrawal syndrome

Correct Answer Logic:

Correct Answer: B — Propofol Infusion Syndrome (PRIS)

Propofol Infusion Syndrome (PRIS) is a rare but life-threatening complication of prolonged high-dose propofol infusion.

Risk factors:

Dose $> 5 \text{ mg/kg/hr}$ (or $> 83 \text{ mcg/kg/min}$) for $> 48$ hours
Concomitant use of catecholamines or corticosteroids
Low carbohydrate intake
Children (higher risk)

Clinical features of PRIS (PRIS mnemonic):

Pink/lipemic plasma, rhabdomyolysis
Renal failure (AKI)
Increase in CK, triglycerides
Severe metabolic acidosis, cardiac failure

Management:

Immediately stop propofol infusion
Switch to alternative sedation (midazolam, dexmedetomidine)
Supportive care (CRRT for renal failure)
Treat metabolic acidosis

Chemistry QUESTION #7804

Question 7133

The pK_b of n-propylamine is approximately:

3.24
3.28✔️
3.32
3.35

Correct Answer Logic:

n-Propylamine is a weak base with K_b ~5×10⁻⁴, pK_b = -log(5×10⁻⁴) ≈ 3.30. Closest is 3.32? Actually standard value ~3.32. But MDCAT often uses 3.28 or 3.32. Given options, 3.32 is common.

Math (Module-1) QUESTION #5470

Question 7135

Line $t$ in the $xy$-plane has slope $-\frac{1}{3}$ and passes through $(9, 10)$. Which equation defines line $t$?

$y = \frac{1}{3}x - 13$
$y = 9x + 10$
$y = -\frac{x}{3} + 10$
$y = -\frac{x}{3} + 13$✔️

Correct Answer Logic:

$y - 10 = -\frac{1}{3}(x - 9) \implies y = -\frac{1}{3}x + 3 + 10 \implies y = -\frac{1}{3}x + 13$.
