MCQs Section QUESTION #4898

A Labor Department study states that the _____ in the past decade and accounted for more than sixty-two percent of the total growth in the civilian work force.

numbers of women employed outside the home grew by more than a thirty-five percent increase
numbers of women employed outside the home grew more than thirty-five percent
numbers of women employed outside the home were raised by more than thirty-five percent
number of women employed outside the home increased by more than thirty-five percent✔️

Correct Answer Logic:

Singular 'number' is correct for a specific measured quantity. 'Increased by more than thirty-five percent' is concise and non-redundant. Options A and E are redundant ('grew by a thirty-five percent increase'). Options B and C use 'numbers' (plural) incorrectly for a singular measured count.

Physics QUESTION #7041

Question 2

The force between two atoms is $F = \alpha \beta \exp \left( -\frac{x^2}{\alpha k T} \right)$, where $x$ is distance, $k$ is Boltzmann constant, and $T$ is temperature. Find the dimensions of $\beta$.

$M^0 L^2 T^{-4}$
$M^2 L T^{-4}$✔️
$M L T^{-2}$
$M^2 L^2 T^{-2}$

Correct Answer Logic:

The exponent must be dimensionless. Thus, $[\alpha] = \frac{[x^2]}{[kT]}$.

Since $[kT]$ has dimensions of energy $[ML^2T^{-2}]$, $[\alpha] = \frac{[L^2]}{[ML^2T^{-2}]} = [M^{-1}T^2]$.

Force $F$ has the same dimensions as $\alpha\beta$.

$[\beta] = \frac{[F]}{[\alpha]} = \frac{[MLT^{-2}]}{[M^{-1}T^2]} = [M^2 L T^{-4}]$.

Question 5

Solve the simultaneous equations: $2x + 3y = 12$ and $x - y = 1$.

x=2 y=3
x=3 y=2✔️
x=4 y=1
x=1 y=4

Correct Answer Logic:

From $x - y = 1$: $x = y + 1$. Substitute into first equation: $2(y+1) + 3y = 12 \Rightarrow 2y + 2 + 3y = 12 \Rightarrow 5y = 10 \Rightarrow y = 2$. Then $x = 3$.

Question 6

Which of the following statements regarding methadone is INCORRECT?

Can be given parenterally
Is an opioid antagonist✔️
Has a long elimination half-life
Has significant analgesic activity

Correct Answer Logic:

Methadone is a full opioid agonist, not an antagonist. It has high oral bioavailability, can be given parenterally, has a long half-life ($24$–$36$ hours), and is an effective analgesic.

Statistics QUESTION #1977

Question 7

In Bowley's coefficient of skewness defined as $S_k = \dfrac{Q_3 + Q_1 - 2Q_2}{Q_3 - Q_1}$, the value lies in the range:

0 to 1
$-1$ to $+1$✔️
$-3$ to $+3$
$-\infty$ to $+\infty$

Correct Answer Logic:

Bowley's coefficient of skewness is bounded between $-1$ and $+1$ because the numerator $Q_3 + Q_1 - 2Q_2$ can never exceed the denominator $Q_3 - Q_1$ in absolute value, since $Q_2$ always lies between $Q_1$ and $Q_3$.

Question 8

Find the average of the first 20 natural numbers.

9.5
10
10.5✔️
11

Correct Answer Logic:

Sum of first $n$ natural numbers $= \dfrac{n(n+1)}{2} = \dfrac{20 \times 21}{2} = 210$. Average $= \dfrac{210}{20} = 10.5$.

Question 9

Which equation represents the 'Alligation Alternate' method for mixing two concentrations $C_{1}$ and $C_{2}$ to get concentration $C_{m}$?

$\frac{Parts_{1}}{Parts_{2}} = \frac{|C_{2} - C_{m}|}{|C_{1} - C_{m}|}$✔️
$\frac{Parts_{1}}{Parts_{2}} = \frac{|C_{1} - C_{2}|}{C_{m}}$
$C_{1}V_{1} = C_{2}V_{2}$
$P = V \times D$

Correct Answer Logic:

Alligation alternate uses the absolute difference between the desired and available concentrations to determine mixing proportions.

$26,480

Correct Answer Logic:

Option A ($18,820) is correct.

Bank statement balance: $22,650

+ Uncleared deposits: +$3,110

− Unpresented cheques: −$6,290

− Bank error (overstated credit): −$650

Cash book balance = $18,820

Question 18

The Rayleigh (energy) method for approximating the fundamental natural frequency equates:

Maximum kinetic energy to maximum potential energy: $T_{max} = V_{max}$ giving $\omega_n^2 = k/m$✔️
Mean kinetic energy to mean potential energy
Damping energy to spring potential energy
Total energy to the product of mass and stiffness

Correct Answer Logic:

Rayleigh's method: for conservative systems in harmonic motion, maximum kinetic energy $T_{max}=\frac{1}{2}m(\omega_n X)^2$ equals maximum potential energy $V_{max}=\frac{1}{2}kX^2$. Setting $T_{max}=V_{max}$: $\omega_n^2=k/m$.
