Correct Answer Logic:

For large $N=1/x$, $[k/x]\approx kN$ with error at most 1.

$x\sum_{k=1}^{15}\left[\dfrac{k}{x}\right] \approx x\sum_{k=1}^{15}\dfrac{k}{x} = \sum_{k=1}^{15}k = \dfrac{15\cdot16}{2} = 120$

More rigorously: $[k/x] = k/x - \{k/x\}$ where $0\leq\{k/x\}<1$. Then $x\cdot\{k/x\}

Question 3
An auditor determines that the probability of a material misstatement occurring is $P(M)$ and the probability that the internal controls fail to detect it is $P(C)$. If the auditor's goal is to keep the total Audit Risk $AR \le 0.05$, which analytical approach is required?
  • Rely solely on the $P(C)$ provided by management
  • Increase the extent of Substantive Testing to reduce Detection Risk✔️
  • Decrease the sample size to save time
  • Ignore $P(M)$ if the company is a Public Company
Correct Answer Logic:
According to ISA 200, Audit Risk is a function of the risks of material misstatement and detection risk. If inherent and control risks are high, the auditor must reduce Detection Risk through increased substantive testing to maintain a low $AR$.

Physics QUESTION #4387
Question 5
For two equal positive charges, the electric field is weakest:
  • Midway between them✔️
  • Along the perpendicular bisector
  • Close to either charge
  • At infinity
Correct Answer Logic:
At the midpoint between two equal positive charges, the electric fields due to each charge are equal in magnitude but opposite in direction, so they cancel out. The resultant electric field is zero (weakest) at this point.

Correct Answer Logic:
Adam Smith introduced the theory of absolute advantage in his landmark 1776 work 'The Wealth of Nations.' He argued that international trade is mutually beneficial when each country specialises in producing goods it can produce more efficiently (at lower absolute cost) than others. David Ricardo later extended this to comparative advantage. Alfred Marshall contributed to marginal utility theory; Lionel Robbins defined economics as the science of scarcity.

Correct Answer Logic:
On smooth: \(a_s = g\sin45°\). On rough: \(a_r = g(\sin45°-\mu_k\cos45°)\). Time ratio: \(t_r/t_s=2\). Since \(L = \frac{1}{2}at^2\): \(t\propto 1/\sqrt{a}\). So \(\frac{t_r}{t_s}=\sqrt{\frac{a_s}{a_r}}=2\Rightarrow \frac{a_s}{a_r}=4\Rightarrow a_r=\frac{a_s}{4}\). \(g(\sin45°-\mu_k\cos45°)=\frac{g\sin45°}{4}\Rightarrow 1-\mu_k=\frac{1}{4}\Rightarrow \mu_k=0.75\).

Physics QUESTION #4381
Question 20
The unit of temperature coefficient of resistivity is:
  • $\dfrac{1}{C}$
  • $\dfrac{1}{K}$✔️
  • $\dfrac{1}{A}$
  • $\dfrac{1}{\Omega}$
Correct Answer Logic:
Temperature coefficient of resistivity $\alpha$ is defined by $\rho = \rho_0(1 + \alpha \Delta T)$. For dimensional consistency, $\alpha = \dfrac{\Delta\rho}{\rho_0 \cdot \Delta T}$, so its unit is $K^{-1}$ or $\dfrac{1}{K}$.
