Question 2
Which generation of computers introduced transistors to replace vacuum tubes?
  • Fourth
  • Third
  • Secondβœ”οΈ
  • First
Correct Answer Logic:
Second Generation computers (1956–1963) replaced vacuum tubes with transistors, invented at Bell Labs in 1947. Transistors were smaller, faster, cheaper, more reliable, and consumed less power. Examples: IBM 7094, UNIVAC 1107. Third generation used ICs; fourth used microprocessors.

Physics QUESTION #7047
Question 3
A pinhole camera box of length $L$ has a hole of radius $a$. The spot size is the sum of geometrical spread and diffraction spread. At what value of $a$ is the spot size $b_{min}$ minimized?
  • $a = \sqrt{\lambda L}$ and $b_{min} = \frac{2\lambda^2}{L}$
  • $a = \sqrt{\lambda L}$ and $b_{min} = \sqrt{4\lambda L}$βœ”οΈ
  • $a = \sqrt{\frac{\lambda L}{2}}$ and $b_{min} = 2\sqrt{2\lambda L}$
  • $a = \frac{\lambda^2}{L}$ and $b_{min} = \frac{2\lambda^2}{L}$
Correct Answer Logic:

Spot size $b \approx \text{geometric spread} + \text{diffraction spread} = a + \frac{L\lambda}{a}$.

To minimize $b$, differentiate with respect to $a$ and set to zero:

$\frac{db}{da} = 1 - \frac{L\lambda}{a^2} = 0 \implies a = \sqrt{\lambda L}$.

Substituting back: $b_{min} = \sqrt{\lambda L} + \frac{L\lambda}{\sqrt{\lambda L}} = 2\sqrt{\lambda L} = \sqrt{4\lambda L}$.

Question 5

What mass of \(\mathrm{Al}_2\mathrm{O}_3\) is produced from 18.5 g Al? \(4\mathrm{Al} + 3\mathrm{O}_2 \rightarrow 2\mathrm{Al}_2\mathrm{O}_3\)
  • 30.8 g
  • 32.6 g
  • 34.9 gβœ”οΈ
  • 36.5 g
Correct Answer Logic:

Molar mass Al = 27 g/mol: moles Al = 18.5/27 = 0.685 mol. From stoichiometry: 4 mol Al β†’ 2 mol Alβ‚‚O₃, so mol Alβ‚‚O₃ = 0.685/2 = 0.3425 mol. Molar mass Alβ‚‚O₃ = 102 g/mol: mass = 0.3425Γ—102 = 34.94 g β‰ˆ 34.9 g.

Mathematics QUESTION #962
Question 8
For a \(3 \times 3\) matrix \(M\), let trace\((M)\) denote the sum of all diagonal elements of \(M\). Let \(A\) be a \(3 \times 3\) matrix such that \(|A| = \dfrac{1}{2}\) and trace\((A) = 3\). If \(B = \text{adj}(\text{adj}(2A))\), then the value of \(|B| + \text{trace}(B)\) equals:
  • 56
  • 132
  • 174
  • 280βœ”οΈ
Correct Answer Logic:
For \(n=3\): \(\text{adj}(\text{adj}(M)) = |M|^{n-2} M\). So \(\text{adj}(\text{adj}(2A)) = |2A|^1 \cdot 2A = 8|A| \cdot 2A = 8A\). Thus \(|B| = |8A| = 8^3|A| = 512 \cdot \frac{1}{2} = 256\) and \(\text{trace}(B) = \text{trace}(8A) = 8\cdot3 = 24\). So \(|B| + \text{trace}(B) = 256 + 24 = 280\).

Question 14
Savannahs are best described as:
  • Tropical rain forests
  • Dense forests with a closed canopy
  • Grasslands with scattered treesβœ”οΈ
  • Grasslands with closely grown trees
Correct Answer Logic:
Savannahs are tropical or subtropical grasslands with scattered, widely spaced trees and shrubs. They are characterised by a continuous grass layer and an open tree canopy (covering 10–30% of the ground). Savannahs experience distinct wet and dry seasons. They cover ~20% of Earth's land surface and are found in Africa (Serengeti), South America (Cerrado), and Australia. They differ from tropical rainforests (closed canopy, high rainfall) and temperate grasslands (no trees).

Question 20

A business owner purchased a delivery vehicle and made these payments:

ItemAmount ($)
Delivery vehicle purchase price28,000
Fitting shelves inside the vehicle3,000
Painting business logo on the vehicle2,000

What was the total capital expenditure?
  • $28,000
  • $30,000
  • $31,000βœ”οΈ
  • $33,000
Correct Answer Logic:

Option C ($31,000) is correct.

Capital expenditure includes costs that bring a non-current asset into use or improve its capacity:

  • Vehicle purchase price: $28,000
  • Fitting shelves (improves functionality): $3,000

Total CapEx = $31,000

Painting the logo ($2,000) is revenue expenditure β€” a marketing cost that does not add to the asset's useful life.
