Psychology QUESTION #9737

Question 6

Stanley Milgram's obedience experiments revealed that ordinary individuals are capable of inflicting harm on others when instructed by an authority figure. Which factor was found to DECREASE obedience in his studies?

The experimenter wearing a white lab coat
The learner being in a different room
The authority figure leaving the room✔️
The experiment being conducted at Yale University

Correct Answer Logic:

Milgram found that obedience decreased significantly when the authority figure (experimenter) was not physically present and gave instructions by telephone. Other factors that decreased obedience included: the learner being in the same room (increasing emotional closeness), the presence of two defiant peers, and moving the study from Yale to a less prestigious location. Physical proximity to authority strongly predicted compliance.

Nursing QUESTION #9225

Question 8

A Charge Nurse notes that a mechanically ventilated patient has a tidal volume (V$_T$) set at $700 \text{ mL}$ and a respiratory rate (RR) of $14 \text{ breaths/min}$. What is the minute ventilation $\dot{V}_E$?

$9.4 \text{ L/min}$
$9.8 \text{ L/min}$✔️
$10.2 \text{ L/min}$
$8.6 \text{ L/min}$

Correct Answer Logic:

Correct Answer: B — $9.8 \text{ L/min}$

Formula for Minute Ventilation:
\[\dot{V}_E = V_T \times RR\]
\[\dot{V}_E = 700 \text{ mL} \times 14 = 9800 \text{ mL/min} = 9.8 \text{ L/min}\]

Clinical significance:

Normal $\dot{V}_E$ = $5 - 8 \text{ L/min}$
This patient's $\dot{V}_E$ of $9.8 \text{ L/min}$ is elevated, risking hyperventilation and respiratory alkalosis
Lung-protective ventilation targets $V_T = 6 \text{ mL/kg}$ ideal body weight (IBW) to prevent ventilator-induced lung injury (VILI)
If IBW = 70 kg, then target $V_T = 6 \times 70 = 420 \text{ mL}$

The Charge Nurse should alert the intensivist to review ventilator settings.

Question 12

What is the primary limitation of Euclidean Zoning in modern urban planning?

It allows mixed-use development
It separates incompatible uses too rigidly✔️
It provides too much flexibility
It ignores environmental concerns

Correct Answer Logic:

Euclidean Zoning (named after Village of Euclid v. Ambler Realty Co.) rigidly separates land uses into single-use zones, leading to sprawl, increased travel distances, and reduced walkability—contradicting contemporary mixed-use and sustainable development principles.

Electronics Engineering QUESTION #11703

Question 13

The Harvard architecture used in many microcontrollers differs from Von Neumann architecture primarily in that:

It uses only 8-bit data buses
Program memory and data memory have separate buses allowing simultaneous fetch and execute✔️
It does not support interrupts
It uses RISC instruction sets exclusively

Correct Answer Logic:

Harvard architecture uses physically separate memory spaces and buses for instructions (program) and data. This allows the CPU to fetch the next instruction while simultaneously reading/writing data memory — a key performance advantage. Von Neumann uses a shared bus, creating the 'Von Neumann bottleneck.' AVR, PIC, and ARM MCUs use modified Harvard architecture.

Question 14

A 100-metre long train passes a bridge at 72 km/hr in 25 seconds. What is the length of the bridge?

400 m✔️
170 m
600 m
None

Correct Answer Logic:

Speed $= 72 \text{ km/hr} = 72 \times \dfrac{1000}{3600} = 20 \text{ m/s}$
Total distance covered in 25 s $= 20 \times 25 = 500$ m
Length of bridge $= 500 - 100 = 400$ m

Dairy Food Science and Technology QUESTION #5954

Question 16

The 'draw-off temperature' during cheddar cheese making (temperature at which whey is drained) is typically:

$15\text{–}18^{\circ}\text{C}$
$38\text{–}40^{\circ}\text{C}$✔️
$55\text{–}60^{\circ}\text{C}$
$25\text{–}28^{\circ}\text{C}$

Correct Answer Logic:

In cheddar making, after cutting, cooking, and cheddaring, the whey is drained ('pitched') and the curd is milled and salted at approximately $38\text{–}40^{\circ}\text{C}$. The cooking step (scalding) heats curd-whey mixture to $37\text{–}40^{\circ}\text{C}$ to promote syneresis before draining.
