Physics QUESTION #7228

Question 1

The dimensional formula of $\Delta Q$, the heat supplied to a system, is:

$M^1L^2T^{-2}$✔️
$M^1L^1T^{-2}$
$M^1L^2T^{-1}$
$ML^1T^{-1}$

Correct Answer Logic:

Heat is a form of energy. Therefore its dimensional formula is the same as that of energy (work).

$[\Delta Q] = [W] = [Fd] = MLT^{-2} \cdot L = ML^2T^{-2}$

Electrical Engineering QUESTION #2194

Question 4

A synchronous generator with inertia constant $H = 5\,\text{MJ/MVA}$ is rated at $100\,\text{MVA}$. The angular momentum coefficient $M = GH/(\pi f_s)$ used in the swing equation (at $50\,\text{Hz}$) is approximately:

$3.18\,\text{MJ s/rad}$✔️
$5.00\,\text{MJ s/rad}$
$0.318\,\text{MJ s/rad}$
$1.59\,\text{MJ s/rad}$

Correct Answer Logic:

Stored kinetic energy $= H\times S_{rated} = 5\times100 = 500\,\text{MJ}$. Swing equation inertia: $M = \frac{GH}{\pi f_s} = \frac{100\times5}{\pi\times50} = \frac{500}{157.08} \approx 3.18\,\text{MJ·s/rad}$.

Question 7

The product of mass and velocity is known as:

Work
Moment
Impulse
Momentum✔️

Correct Answer Logic:

Momentum is defined as the product of mass and velocity: $\vec{p} = m\vec{v}$. It is a vector quantity measured in $\text{kg·m/s}$. Work is force times displacement, impulse is force times time (equal to change in momentum), and moment refers to torque.

Agronomy QUESTION #2017

Question 9

Primary tillage differs from secondary tillage in that primary tillage:

Is performed closer to sowing time with lighter implements
Breaks the soil to greater depths and is performed soon after harvest of the previous crop✔️
Is exclusively used for inter-row cultivation during crop growth
Involves only the surface 2–3 cm of soil

Correct Answer Logic:

Primary tillage refers to deep initial tillage (e.g., moldboard or disc plowing) performed after harvest to break up compacted soil. Secondary tillage involves shallower, finer operations (harrowing, leveling) performed closer to sowing to refine the seedbed.

CISA QUESTION #1722

Question 13

Which of the following statements most accurately characterises the concept of auditor independence?

Independence is not a relevant concern for auditors employed by a consulting firm.
Independence is an essential requirement specifically for external audits.✔️
An internal auditor achieves independence solely by completing a formal certification programme.
The audit committee formally confers independence upon the auditor.

Correct Answer Logic:

Auditor independence is the cornerstone of a credible and objective audit. An auditor who has a personal, financial, or organisational relationship with the entity being audited risks rendering a biased opinion. Independence is most critical — and most strictly required — in external audits, where the results will be relied upon by third parties. Internal auditors may face structural independence limitations due to their employment relationship with the auditee.
