AMALGAMATE means to combine or merge different things into one unified whole. Its antonym is separate — to divide or pull apart. 'Study' means to examine. 'Circulate' means to move around. 'Reduce' means to make smaller. Only 'separate' directly opposes the merging/combining meaning of amalgamate.

Chemistry QUESTION #1089

Question 2448

The ratio of wavelengths of light absorbed by hydrogen atom for $n=2\to n=3$ and $n=4\to n=6$ transitions is:

$\dfrac{1}{9}$
$\dfrac{1}{4}$✔️
$\dfrac{1}{36}$
$\dfrac{1}{16}$

Correct Answer Logic:

For hydrogen: $\frac{1}{\lambda} = R_H\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$. Transition 1 ($n=2\to3$): $\frac{1}{\lambda_1}=R_H\left(\frac{1}{4}-\frac{1}{9}\right)=R_H\cdot\frac{5}{36}$. Transition 2 ($n=4\to6$): $\frac{1}{\lambda_2}=R_H\left(\frac{1}{16}-\frac{1}{36}\right)=R_H\cdot\frac{5}{144}$. Ratio: $\frac{\lambda_1}{\lambda_2}=\frac{5/144}{5/36}=\frac{36}{144}=\frac{1}{4}$.

Education QUESTION #10903

Question 2449

A portfolio in education is a collection of:

School records
Teacher's work
Student work✔️
Office work

Correct Answer Logic:

An educational portfolio is a purposeful collection of student work gathered over time that demonstrates learning progress, achievement, effort, and reflection. It may include essays, projects, tests, artwork, reflections, and other work samples. Portfolios are used for authentic assessment, showing the development of student competencies over time. They give students agency in their assessment and provide a richer picture of learning than single tests.

Question 2450

Raymond B. Cattell advanced the study of personality traits by using a statistical method called:

Locus of control
Identification
Factor analysis✔️
Phrenology

Correct Answer Logic:

Cattell used factor analysis to reduce many surface traits to a smaller set of underlying source traits (16PF). Factor analysis has since been used by Eysenck and Costa & McCrae (Big Five) in personality research.

Statistics QUESTION #1960

Question 2451

If $P(A)$ is the probability of event A, which expression correctly gives the probability of its complement $A^c$?

$1 + P(A)$
$1 - P(A)$✔️
$P(A)$
$P(A) - 1$

Correct Answer Logic:

By the complement rule of probability, $P(A^c) = 1 - P(A)$. Since $P(A) + P(A^c) = 1$, the complement probability is always $1 - P(A)$.

Electronics Engineering QUESTION #11730

Question 2456

A power analyser measures: $V_{rms} = 230\,\text{V}$, $I_{rms} = 10\,\text{A}$, $P = 1840\,\text{W}$. The power factor and reactive power $Q$ are:

$\text{PF} = 0.80$; $Q = 1380\,\text{VAR}$✔️
$\text{PF} = 0.85$; $Q = 1200\,\text{VAR}$
$\text{PF} = 1.0$; $Q = 0\,\text{VAR}$
$\text{PF} = 0.90$; $Q = 1000\,\text{VAR}$

Correct Answer Logic:

$S = V_{rms} \times I_{rms} = 230 \times 10 = 2300\,\text{VA}$. $\text{PF} = \dfrac{P}{S} = \dfrac{1840}{2300} = \mathbf{0.80}$. $Q = \sqrt{S^2 - P^2} = \sqrt{2300^2 - 1840^2} = \sqrt{5290000 - 3385600} = \sqrt{1904400} \approx \mathbf{1380\,\text{VAR}}$.

Question 2457

The shutdown point for a competitive firm in the short run occurs where price falls:

Below average total cost but above average variable cost
Below the minimum point of $AVC$✔️
Below average fixed cost only
To exactly equal marginal cost at any output

Correct Answer Logic:

A firm shuts down when price drops below minimum $AVC$, since it cannot even cover variable costs by operating.

Question 2459

The total axial deformation $\delta$ of a bar of length $l$, cross-sectional area $A$, modulus of elasticity $E$, under axial force $F$ is:

$\delta = \frac{AE}{Fl}$
$\delta = \frac{Fl}{AE}$✔️
$\delta = \frac{FA}{El}$
$\delta = FAEl$

Correct Answer Logic:

From Hooke's Law: $\sigma = E\varepsilon$, where $\sigma = F/A$ and $\varepsilon = \delta/l$. Solving: $\delta = Fl/(AE)$.

Psychology QUESTION #9833

Question 2460

Self-assertive behaviour is an example primarily of:

An abundancy motive
A stimulation motive✔️
A survival motive
A security motive

Correct Answer Logic:

Self-assertion — expressing one's needs, opinions, and boundaries — is driven by a stimulation motive (need for agency, growth, and self-expression). It goes beyond survival needs and reflects higher-order drives for autonomy and impact.
