Physics QUESTION #985

Question 8

A symmetric thin biconvex lens is cut into four equal parts by two planes $AB$ and $CD$. If the power of the original lens is 4 D, then the power of a part of the divided lens is:

1 D
8 D✔️
2 D
4 D

Correct Answer Logic:

Cutting along $AB$ (perpendicular to axis) halves the lens — each half-lens has the same radii but acts as a plano-convex lens; power doubles to 8 D. Cutting along $CD$ (along the axis) does not change power. Each quarter piece has power 8 D.

Question 9

If $T:\mathbb{R}^3\to\mathbb{R}^2$ is a linear transformation with $\text{rank}(T)=2$, then by the Rank-Nullity Theorem, the dimension of the kernel is:

$0$
$1$✔️
$2$
$3$

Correct Answer Logic:

Rank-Nullity Theorem: $\dim(\ker T)+\text{rank}(T)=\dim(\mathbb{R}^3)=3$. Given $\text{rank}(T)=2$: $\dim(\ker T)=3-2=1$.

Question 11

A compounded suspension requires sucralfate $1$ g tablets $\times 8$, sorbitol $70\%$ solution $40$ mL, water to $120$ mL. What percentage (w/v) does sucralfate represent in the final preparation?

In a sales mix decision, the product with the highest contribution margin per unit should be:

Sold exclusively, regardless of customer demand.
Prioritized when resources are constrained.✔️
Avoided to reduce risk.
Discounted to maximize revenue.

Correct Answer Logic:

The product yielding the highest contribution margin per scarce resource should be prioritized to maximize total contribution and profit. Selling exclusively ignores demand and other constraints.

Economics QUESTION #1710

Question 20

According to the World Bank's income classification using GNI per capita (Atlas method), Pakistan is currently placed in which income category?

Low-income developing economy
Upper-middle-income economy
Lower-middle-income developing economy✔️
None of these

Correct Answer Logic:

The World Bank classifies Pakistan as a lower-middle-income country (LMIC). As of recent classifications, Pakistan's GNI per capita falls within the lower-middle-income range (approximately USD 1,136–4,465). It is above the low-income threshold but well below the upper-middle-income threshold. This classification affects Pakistan's access to concessional lending (IDA blend status) and its obligations under various international agreements.
