Electrical Engineering QUESTION #2168

In the two-wattmeter method for a balanced three-phase load, $W_1 = 1500\,\text{W}$ and $W_2 = 500\,\text{W}$. The load power factor is:

$0.866$✔️
$0.707$
$0.5$
$0.75$

Correct Answer Logic:

$\tan\phi = \frac{\sqrt{3}(W_1-W_2)}{W_1+W_2} = \frac{\sqrt{3}(1000)}{2000} = \frac{\sqrt{3}}{2}$, so $\phi = 30°$ and $\text{pf} = \cos 30° \approx 0.866$.

Mathematics QUESTION #7490

Question 7

The sum of first 20 terms of the sequence 0.7, 0.77, 0.777, … is:

$\frac{7}{81}(179-10^{-20})$
$\frac{7}{9}(99-10^{-20})$
$\frac{7}{81}(179+10^{-20})$✔️
$\frac{7}{9}(99+10^{-20})$

Correct Answer Logic:

Each term: $0.7 = \frac{7}{9}(1-10^{-1})$, $0.77 = \frac{7}{9}(1-10^{-2})$, etc. Sum = $\frac{7}{9}\sum_{k=1}^{20}(1-10^{-k}) = \frac{7}{9}[20 - \frac{10^{-1}(1-10^{-20})}{1-10^{-1}}] = \frac{7}{9}[20 - \frac{1-10^{-20}}{9}] = \frac{7}{9} \cdot \frac{180-1+10^{-20}}{9} = \frac{7}{81}(179+10^{-20})$.

Accounting & Finance QUESTION #9659

Question 10

A firm's goods are sold at a margin of 25% on sales. Purchases = Rs. 155,000; Opening Stock = Rs. 10,000; Closing Stock = Rs. 15,000. What are total Sales?

Rs. 200,000✔️
Rs. 150,000
Rs. 187,500
Rs. 175,000

Correct Answer Logic:

COGS = 10,000 + 155,000 – 15,000 = Rs. 150,000. Margin = 25%, so COGS = 75% of Sales. Sales = 150,000 × 100/75 = Rs. 200,000. The margin formula: Sales = COGS/(1 – Margin%) = 150,000/0.75.

"She didn't even take her gloves off. She lowered her eyes and drummed on the table..."

Correct Answer Logic:

Dabbing her "lovely nose" (pleasant appearance) after loathing the puff (unpleasant attitude) shows contrast.

Federal Rules of Evidence (US) QUESTION #3794

Question 13

During a civil trial, a witness for the plaintiff testifies. On cross, the defense asks a question that implies the witness is lying because he was paid a bribe by the plaintiff. On redirect, the plaintiff offers a statement the witness made to his wife *before* the alleged bribe was paid, which is consistent with his trial testimony. Is the statement admissible?

No, it's hearsay.
Yes, as non-hearsay to rebut a charge of recent fabrication or improper motive under Rule 801(d)(1)(B).✔️
No, because the statement was made to his wife and is privileged.
Yes, but only for impeachment and not as substantive evidence.

Correct Answer Logic:

Rule 801(d)(1)(B) defines as 'not hearsay' a prior consistent statement offered to rebut a charge of recent fabrication or improper influence/motive, provided the statement was made *before* the motive to lie arose.

Mathematics QUESTION #4134

Question 17

$\vec{r}$
$\frac{\vec{r}}{r}$✔️
$\frac{\vec{r}}{r^2}$
$\hat{r}$

Journalism / Mass Communication QUESTION #6418

Question 20

The Digital Sutra was the earliest known printed text. In what year was it printed, and what type of text was it?

Koran printed in Baghdad in 794 AD
Diamond Sutra (a Buddhist scripture) printed in China in 868 AD using block printing✔️
Gutenberg Bible printed in Germany in 1453 using movable type
The first Bible printed in Andalusia in the 1480s using Hebrew script

Correct Answer Logic:

The textbook states: “the earliest known printed text, the Diamond Sutra (a Buddhist scripture), was printed in China in 868 A.D.” It was created using block printing — a technique where individual pages are carved into wooden blocks and pressed onto paper. This text predates Gutenberg's press by nearly 600 years. The Diamond Sutra is a famous Mahayana Buddhist scripture, and the printed copy (now held in the British Library) is remarkable for its technical quality, indicating the technique had been refined over time before this particular copy was made. Note the other important dates: paper milling in Baghdad began as early as 794 AD; Bi Sheng invented movable type in 1041 AD; Gutenberg developed the European printing press in the 1440s; and the first printing press in Muslim territory (Andalusia) operated in the 1480s.
