Question 3868

In transportation capacity analysis, what is the theoretical maximum capacity (vehicles/hour) for one lane at 100 km/h with 2-second headway?

1,000
1,200
1,500
1,800✔️

Correct Answer Logic:

Capacity = $\frac{3600 \text{ seconds/hour}}{\text{headway in seconds}} = \frac{3600}{2} = 1800$ vehicles/hour/lane. This represents maximum theoretical throughput; practical capacity is typically 70-80% of theoretical due to speed variations and driver behavior.

Physics QUESTION #1177

Question 3872

A photon having the same energy as an electron has wavelength __________ as electron's De Broglie wavelength.

Shorter
Longer✔️
Same
None of these

Correct Answer Logic:

For an electron: $\lambda_e = \frac{h}{\sqrt{2m_eE}}$. For a photon: $\lambda_{ph} = \frac{hc}{E}$. Ratio: $\frac{\lambda_{ph}}{\lambda_e} = \frac{hc}{E} \cdot \frac{\sqrt{2m_eE}}{h} = c\sqrt{\frac{2m_e}{E}}$. For typical energies, this ratio $\gg 1$, meaning the photon's wavelength is much longer than the electron's De Broglie wavelength at the same energy.

English QUESTION #4440

Question 3874

To become a write think of a plot-make points on how the story will progress and pen it down. The phrase ‘pen it down’ here means:

To writ
To write✔️
To throw the pen
To throw it down

Correct Answer Logic:

The phrase "pen it down" means **to write** because in this context, "pen" is used as a verb meaning "to write or compose," and "down" suggests putting thoughts onto paper. The passage ends with the instruction: *"Think of a plot—make points on how the story will progress and pen it down,"* which clearly encourages the reader to write the plot points on paper. The other options—"to writ" (an archaic or incorrect form), "to throw the pen," or "to throw it down"—do not fit the logical or grammatical meaning of the sentence.

Question 3876

In PERT analysis, if optimistic time is 5 days, most likely time is 8 days, and pessimistic time is 17 days, what is the expected time?

8 days
9 days✔️
10 days
11 days

Correct Answer Logic:

PERT expected time formula: $t_e = \frac{t_o + 4t_m + t_p}{6} = \frac{5 + 4(8) + 17}{6} = \frac{54}{6} = 9$ days. This beta distribution-based calculation weighs the most likely time more heavily than optimistic/pessimistic estimates.

Question 3878

The lactose content of milk accounts for approximately what percentage of its caloric content?

$5\%$
$27\text{–}30\%$
$45\text{–}50\%$✔️
$70\%$

Correct Answer Logic:

Lactose ($\approx 4.8\%$ in milk, $4\;\text{kcal/g}$) provides approximately $28\text{–}30\%$ of total milk calories. Whole milk energy: fat ($3.5\% \times 9\;\text{kcal/g} \approx 3.2\;\text{kcal/100 mL}$), protein ($3.2\% \times 4 \approx 1.3\;\text{kcal}$), lactose ($4.8\% \times 4 \approx 1.9\;\text{kcal}$). Lactose share $= \frac{1.9}{6.4} \approx 30\%$.

Question 3880

The scalar triple product $\mathbf{A} \cdot (\mathbf{B} \times \mathbf{C})$ geometrically represents:

The magnitude of the vector $\mathbf{B} \times \mathbf{C}$
The volume of the parallelepiped formed by $\mathbf{A}$, $\mathbf{B}$, $\mathbf{C}$✔️
The area of the triangle formed by the three vectors
The dot product of $\mathbf{B}$ and $\mathbf{C}$ projected onto $\mathbf{A}$

Correct Answer Logic:

The scalar triple product $\mathbf{A}\cdot(\mathbf{B}\times\mathbf{C})$ equals the volume of the parallelepiped whose three edges are represented by vectors $\mathbf{A}$, $\mathbf{B}$, and $\mathbf{C}$. If the result is zero, the vectors are coplanar.
