Psychology QUESTION #1467
Question 2663
Who is associated with the concept of fluid intelligence and crystallized intelligence?
  • Jean Piaget
  • Raymond Cattell✔️
  • Charles Spearman
  • Howard Gardner
Correct Answer Logic:
Raymond Cattell (and later John Horn) proposed the distinction between fluid intelligence (Gf) — the ability to reason and solve novel problems, independent of acquired knowledge — and crystallized intelligence (Gc) — accumulated knowledge and skills from experience and education. This distinction is central to the Cattell-Horn-Carroll (CHC) theory of cognitive abilities.

Physics QUESTION #7075
Question 2665
An X-ray tube functions at a potential of $1.24$ million volts. Calculate the shortest wavelength produced by the photons in this tube.
  • $10^{-3} \text{ nm}$✔️
  • $10^{-2} \text{ nm}$
  • $10^{-4} \text{ nm}$
  • $10^{-1} \text{ nm}$
Correct Answer Logic:
The shortest wavelength ($\lambda_{min}$) is given by $\lambda = \frac{hc}{eV}$. Using $hc \approx 1240 \text{ eV}\cdot\text{nm}$, we have $\lambda = \frac{1240 \text{ eV}\cdot\text{nm}}{1.24 \times 10^6 \text{ eV}} = 1000 \times 10^{-6} \text{ nm} = 10^{-3} \text{ nm}$.

Nursing QUESTION #9137
Question 2666
A nurse is monitoring a woman receiving IV Magnesium Sulfate for eclampsia prophylaxis. Which finding requires IMMEDIATE cessation of the infusion and administration of the antidote?
  • Serum Mg²⁺ level of 4–7 mEq/L
  • Respiratory rate of 10/min with absent patellar reflexes✔️
  • Urine output of 35 mL/hour
  • Mild sedation and flushing
Correct Answer Logic:

Magnesium Sulfate Toxicity monitoring is a critical nursing responsibility:

Serum Mg²⁺ LevelClinical Effect
\(1.5{-}2.5\,\text{mEq/L}\)Normal therapeutic range
\(4{-}7\,\text{mEq/L}\)Therapeutic anticonvulsant range
\(5{-}10\,\text{mEq/L}\)Loss of deep tendon reflexes (first sign of toxicity)
\(10{-}13\,\text{mEq/L}\)Respiratory paralysis ← DANGER
\(>15\,\text{mEq/L}\)Cardiac arrest

Stop infusion IMMEDIATELY if:

  • Respiratory rate \(<12/\text{min}\)
  • Absent patellar (deep tendon) reflexes — earliest clinical sign
  • Urine output \(<25{-}30\,\text{mL/hr}\) (Mg is renally excreted)
  • O₂ saturation falling

Antidote: Calcium Gluconate 1 g (10 mL of 10% solution) IV over 10 minutes — must be at bedside at all times.

Urine output of 35 mL/hr is acceptable (minimum 25–30 mL/hr). Flushing and sedation are normal side effects, not toxicity signs.

Mathematics QUESTION #4126
Question 2667
For $f(z) = \frac{1}{z} = \frac{\cos(\theta)}{r} - i\frac{\sin(\theta)}{r}$ in polar form, compute $u_r$ and verify C-R equations. What is $u_r$?
  • $-\frac{\cos(\theta)}{r^2}$✔️
  • $-\frac{1}{r^2}$
  • $\frac{\cos(\theta)}{r}$
  • $\frac{1}{r}$
Correct Answer Logic:
$u = \frac{\cos(\theta)}{r}$, so $u_r = -\frac{\cos(\theta)}{r^2}$. Also $v = -\frac{\sin(\theta)}{r}$, so $v_\theta = -\frac{\cos(\theta)}{r}$. Then $\frac{1}{r}v_\theta = -\frac{\cos(\theta)}{r^2} = u_r$. C-R satisfied.

Math Physics Chemistry Biology QUESTION #4281
Question 2668
The complementary base pairing in DNA is important because it:
  • Maintains the tertiary structure of enzymes
  • Provides energy for all cell metabolism
  • Enables protein to fold properly
  • Allows DNA to act as a genetic blueprint during replication✔️
Correct Answer Logic:
Complementary base pairing (A–T, G–C) ensures accurate replication — each strand acts as a template, making DNA the reliable genetic blueprint.

Geography QUESTION #1248
Question 2669
Fossils are never found in:
  • Shale
  • Granite✔️
  • Sandstone
  • None of these
Correct Answer Logic:
Fossils are only found in sedimentary rocks (such as shale, sandstone, limestone) because they form from the gradual burial and compression of organic remains in sediments. Granite is an igneous rock formed from the cooling of magma at high temperatures and pressures — any organic material would be destroyed under such conditions. Therefore fossils are never found in granite or other igneous/metamorphic rocks.

Chemistry QUESTION #7414
Question 2673
The acidity of diprotic acids in aqueous solution increases in the order:
  • \(\text{H}_2\text{S} < \text{H}_2\text{Se} < \text{H}_2\text{Te}\)✔️
  • \(\text{H}_2\text{Se} < \text{H}_2\text{S} < \text{H}_2\text{Te}\)
  • \(\text{H}_2\text{Te} < \text{H}_2\text{S} < \text{H}_2\text{Se}\)
  • \(\text{H}_2\text{Se} < \text{H}_2\text{Te} < \text{H}_2\text{S}\)
Correct Answer Logic:
Acid strength of hydrides (Group 16):
Down the group, bond length increases (H–X bond gets weaker), making it easier to release H⁺. Therefore acid strength increases down the group:

\(\text{H}_2\text{O} < \text{H}_2\text{S} < \text{H}_2\text{Se} < \text{H}_2\text{Te}\)

Note: This trend is opposite to electronegativity trend, and is governed by bond dissociation energy.

  • It involves no paperwork
Correct Answer Logic:
Audits are deep, structured evaluations used to ensure that security programs meet national and international standards.

  • The leave period is counted toward pension only
  • The leave is regularized as earned leave
Correct Answer Logic:
Rule 8-A explicitly provides that if such a government servant is not punished he shall rejoin duty and the leave period shall be treated as duty on full pay.
