Question 5

A necessary and sufficient condition for a linear feedback system to be stable is that:

All poles of the closed-loop transfer function have positive real parts
All poles of the closed-loop transfer function have negative real parts✔️
The gain $K$ is greater than 1
The system has no zeros in the right-half s-plane

Correct Answer Logic:

Stability condition: all poles of the closed-loop transfer function must have negative real parts (lie in the left-half s-plane). If any pole has a positive real part, the response grows without bound (unstable).

Chemistry QUESTION #7385

Question 6

The four orbitals 4d, 5p, 5f, and 6p, arranged in order of decreasing energy, give the correct sequence:

5f > 6p > 5p > 4d✔️
6p > 5f > 5p > 4d
6p > 5f > 4d > 5p
5f > 6p > 4d > 5p

Correct Answer Logic:

Using $(n + \ell)$ rule:

5f: $n+\ell = 5+3 = 8$
6p: $n+\ell = 6+1 = 7$
5p: $n+\ell = 5+1 = 6$
4d: $n+\ell = 4+2 = 6$, but lower $n$ so lower energy than 5p

Decreasing energy order: 5f > 6p > 5p > 4d

Mathematics QUESTION #7465

Question 17

A man is walking towards a vertical pillar in a straight path, at a uniform speed. At a certain point A on the path, he observes that the angle of elevation of the top of the pillar is 30°. After walking for 10 minutes from A in the same direction, at a point B, he observes that the angle of elevation of the top of the pillar is 60°. Then the time taken (in minutes) by him, from B to reach the pillar, is:

10
20
5✔️
6

Correct Answer Logic:

Let the height of pillar be $h$ and the man's speed be $v$. Let distances from pillar be $d_A$ at A and $d_B$ at B. From angles: $\tan 30° = \frac{h}{d_A}$ gives $d_A = h\sqrt{3}$, and $\tan 60° = \frac{h}{d_B}$ gives $d_B = \frac{h}{\sqrt{3}}$. Distance AB = $d_A - d_B = h\sqrt{3} - \frac{h}{\sqrt{3}} = \frac{3h-h}{\sqrt{3}} = \frac{2h}{\sqrt{3}}$. Time for AB is 10 minutes, so $v = \frac{2h}{\sqrt{3} \cdot 10} = \frac{h}{5\sqrt{3}}$. Time from B to pillar = $\frac{d_B}{v} = \frac{h/\sqrt{3}}{h/(5\sqrt{3})} = 5$ minutes.

Question 18

What does the Location Quotient (LQ) measure in regional economic analysis?

Absolute employment in a sector
Regional specialization in an industry✔️
Total regional GDP
Population density

Correct Answer Logic:

Location Quotient formula $LQ = \frac{(e_i/e)}{(E_i/E)}$ compares a region's share of employment in sector $i$ to the national share. LQ > 1 indicates regional specialization; LQ < 1 indicates underrepresentation relative to national average.

Accounting & Finance QUESTION #9620

Question 20

A provision for bad debts is maintained at 5% of year-end debtors. On July 1 the opening provision balance is Rs. 3,400. During the year, bad debts written off total Rs. 5,000. At June 30 the debtors' closing balance (after write-offs) is Rs. 75,000. What is the net charge/credit to the Profit & Loss Account in respect of bad debts and the provision for the year?

Charge Rs. 5,350 (bad debts Rs. 5,000 + provision increase Rs. 350)✔️
Charge Rs. 5,000 (bad debts only; provision decreases)
Credit Rs. 2,650 (net provision release)
Charge Rs. 8,750 (bad debts Rs. 5,000 + new provision Rs. 3,750)

Correct Answer Logic:

Required closing provision = 75,000 × 5% = Rs. 3,750. Opening provision = Rs. 3,400. Since the provision must increase, additional provision charged to P&L = 3,750 – 3,400 = Rs. 350. Bad debts of Rs. 5,000 are also charged to P&L. Total P&L charge = Rs. 5,000 + Rs. 350 = Rs. 5,350.
