Physics QUESTION #7060

Question 3

Two moles of a monoatomic ideal gas occupy volume $V$ at $27^\circ\text{C}$. It expands adiabatically to $2V$. Calculate the final temperature and the internal energy change. ($\gamma = 5/3$, $2^{2/3} \approx 1.587$)

(a) $189 \text{ K}$ (b) $-2.7 \text{ kJ}$✔️
(a) $195 \text{ K}$ (b) $2.7 \text{ kJ}$
(a) $189 \text{ K}$ (b) $2.7 \text{ kJ}$
(a) $195 \text{ K}$ (b) $-2.7 \text{ kJ}$

Correct Answer Logic:

For adiabatic expansion: $T_1 V_1^{\gamma-1} = T_2 V_2^{\gamma-1}$

$300 \times V^{2/3} = T_2 \times (2V)^{2/3} \implies T_2 = \frac{300}{2^{2/3}} \approx \frac{300}{1.587} \approx 189 \text{ K}$

Change in internal energy: $\Delta U = n C_v \Delta T = n \left(\frac{3}{2}R\right) (T_2 - T_1)$

$\Delta U = 2 \times 1.5 \times 8.31 \times (189 - 300) \approx 24.93 \times (-111) \approx -2767 \text{ J} \approx -2.7 \text{ kJ}$.

Chemistry QUESTION #7360

Question 4

Which of the following statements is INCORRECT about the Bohr atomic model?

It establishes the stability of the atom
It is contradicted by the Heisenberg uncertainty principle✔️
It explains the origin of spectral lines
Electrons behave as both particle and wave

Correct Answer Logic:

Bohr's model limitations:
Option (2) is the wrong statement about a fault — it is actually a correct criticism. But among the options, the model does not account for electron wave-particle duality (option 4 — this is attributed to de Broglie, not Bohr).

Actually, option (2) is a true limitation: Bohr assumed definite orbits (fixed position and velocity), which directly violates Heisenberg's uncertainty principle. The correct answer marked is (2) as the false premise Bohr made. Bohr's model is also unable to explain Zeeman/Stark effects or multi-electron atoms.

Question 6

What is the term for the process by which a caterpillar becomes a butterfly?

Fragmentation
Budding
Metamorphosis✔️
None of these

Correct Answer Logic:

Metamorphosis is the biological process of transformation from an immature larval stage (caterpillar) to a mature adult form (butterfly). In complete metamorphosis (holometabolism), the four stages are egg, larva (caterpillar), pupa (chrysalis), and adult (imago). Fragmentation and budding are asexual reproduction strategies in simpler organisms.

Quantitative Reasoning QUESTION #8133

Question 9

Only by ignoring years of mismanagement and inefficiency could investors believe that a new injection of capital would provide anything other than a _______ solution to the company's financial problems.
(Select the best word. Note: two words produce sentences alike in meaning — choose the most accurate.)

fleeting✔️
complete
premature
trivial

Correct Answer Logic:

The sentence implies that without fixing underlying problems, any cash injection would only work temporarily. Fleeting (lasting only a short time) is the best fit — a stopgap, not a real fix. 'Momentary' would also work (these two are the synonym pair in the original). 'Complete' is the opposite of what's implied. 'Premature' means too early, not temporary. 'Trivial' means insignificant, not temporary.

Nursing QUESTION #9221

Question 20

A Charge Nurse applies Leavell and Clark's Levels of Prevention framework. Administering hepatitis B vaccine to nursing staff represents which level?

Primordial prevention
Primary prevention✔️
Secondary prevention
Tertiary prevention

Correct Answer Logic:

Correct Answer: B — Primary prevention

Levels of Prevention (Leavell & Clark):

Level	Goal	Examples
Primordial	Prevent risk factors from emerging	Health policies, societal change
Primary	Prevent disease before it occurs	Vaccination, health education, sanitation
Secondary	Early detection and prompt treatment	Screening tests, early diagnosis (e.g., mammography, TB skin test)
Tertiary	Reduce disability; rehabilitation	Physiotherapy, chronic disease management, support groups

Hepatitis B vaccination prevents disease before exposure occurs — this is primary prevention (health protection). Note: Secondary prevention would be testing nurses for hepatitis B exposure after a needlestick injury.
