Biology QUESTION #4261

If a normal person marries with a colour blind female, what will be the possibility of a normal male child?

0%✔️
25%
50%
75%

Correct Answer Logic:

A colour blind female has genotype $X^c X^c$. A normal male has genotype $X^N Y$. All sons receive $X^c$ from mother and $Y$ from father, making all sons colour blind ($X^c Y$). So 0% chance of a normal male child.

Question 2

For a first-order reaction, 32% of the reactant remains after 570 s. Calculate the rate constant $k$ (in $\times10^{-3}\ s^{-1}$, rounded to nearest integer). [Given: $\log_{10}2 = 0.301$, $\ln 10 = 2.303$]

3✔️

Correct Answer Logic:

For first-order: $k = \frac{2.303}{t}\log\frac{[A]_0}{[A]} = \frac{2.303}{570}\log\frac{100}{32} = \frac{2.303}{570}\log\left(\frac{25}{8}\right)$. $\log\frac{25}{8} = \log 25 - \log 8 = (2\log 5)-(3\log 2) = 2(1-0.301)-3(0.301) = 2(0.699)-0.903 = 1.398-0.903 = 0.495$. $k = \frac{2.303\times0.495}{570} = \frac{1.14}{570} \approx 2\times10^{-3}\ s^{-1}$. Nearest integer = $2\times10^{-3}\ s^{-1}$.

Statistics QUESTION #2002

Question 7

Using the same company data (800 employees, 160 degree holders, 272 managers, 80 are both), the conditional probability $P(\text{college graduate} \mid \text{manager})$ is:

$\dfrac{80}{160}$
$\dfrac{80}{272}$✔️
$\dfrac{272}{800}$
$\dfrac{160}{272}$

Correct Answer Logic:

$P(\text{grad} \mid \text{manager}) = \dfrac{P(\text{grad} \cap \text{manager})}{P(\text{manager})} = \dfrac{80/800}{272/800} = \dfrac{80}{272} \approx 0.294$. This is the definition of conditional probability.

Question 8

Find the value of $x$ if $\sqrt{x} + 12 = 20$.

8
64✔️
16
400

Correct Answer Logic:

Subtract $12$ from both sides: $\sqrt{x} = 8$. Square both sides: $x = 8^2 = 64$.

Question 9

A sum of money doubles itself at Simple Interest in 10 years. What is the rate of interest per annum?

8%
10%✔️
12%
15%

Correct Answer Logic:

If principal $= P$, then SI $= P$ (since it doubles). $P = \dfrac{P \times R \times 10}{100} \Rightarrow 1 = \dfrac{R \times 10}{100} \Rightarrow R = 10\%$ per annum.

Commerce QUESTION #1216

Question 10

When issuing an unqualified opinion, the auditor who evaluates audit findings should be satisfied that the:

Amount of known misstatement is documented in working papers
Estimates of the total likely misstatement is less than materiality level✔️
Estimates of the total likely misstatement is more than materiality level
Estimates of the total likely misstatement cannot be made

Correct Answer Logic:

An unqualified (clean) audit opinion is issued when the auditor concludes that the financial statements are free from material misstatement. This requires that the estimated total likely misstatement (both known and projected) is less than the materiality level established for the audit. If misstatements exceed materiality, a qualified or adverse opinion is required.

Physics QUESTION #1182

Question 13

The rate of change of current in a coil is proportional to:

V
−emf✔️
R
None of these

Correct Answer Logic:

By Faraday's law of electromagnetic induction, the induced emf in an inductor is $\mathcal{E} = -L\frac{dI}{dt}$. Rearranging: $\frac{dI}{dt} = -\frac{\mathcal{E}}{L}$. So the rate of change of current is proportional to the negative of the induced emf ($-\mathcal{E}$). The negative sign (Lenz's law) indicates opposition to the change.

Question 14

The force F experienced by a conductor of length L carrying current when placed in a uniform magnetic field B is:

F = B/iL
F = IL/B
F = BiL✔️
F = L x B/I

Correct Answer Logic:

The force on a current-carrying conductor in a magnetic field is F = BIL sinθ. For perpendicular field F = BiL.

Question 16

For a proportional (P) control element with gain $K$, the transfer function is:

$Y(s) = K/s$
$Y(s) = Ks$
$Y(s) = K$✔️
$Y(s) = K s^2$

Correct Answer Logic:

A proportional element: $x_o(t)=K x_i(t)$, so in Laplace domain $X_o(s)=K X_i(s)$, giving transfer function $Y(s)=K$ (a constant gain).

Question 17

In the Event Management course, the 'AIDA' framework referenced under feasibility analysis refers to which concept?

An advanced inventory and distribution assessment for event catering
A marketing communication model: Attention, Interest, Desire, and Action — used to structure event marketing and promotional strategy✔️

AIDA (Attention, Interest, Desire, Action) is a foundational marketing communication model that guides how promotional messages for events are structured to move audiences from awareness to ticket purchase or attendance.
