Boilers Mechanical Engineering QUESTION #2393

Question 2

The bandwidth $\omega_b$ of a closed-loop control system is defined as the frequency at which the closed-loop magnitude $M(\omega)$ drops to:

$M(\omega_b) = M(0)/2$
$M(\omega_b) = M(0)/\sqrt{2}$ (i.e., $-3$ dB below $M(0)$)✔️
$M(\omega_b) = 0$
$M(\omega_b) = M(0) \cdot \sqrt{2}$

Correct Answer Logic:

Bandwidth: $M(\omega_b)=M(0)/\sqrt{2}$, i.e., the response is $-3$ dB below its low-frequency value. In dB: $20\log M(\omega_b)=20\log M(0)-3$ dB. Larger bandwidth means faster system response.

Statistics QUESTION #2009

Question 4

In the ANOVA table for an RCB design with $SS_{error} = 2.6249$ and error $df = 24$, the standard error for the difference between two treatment means $(\bar{y}_{i.} - \bar{y}_{j.})$ is:

$\sqrt{\dfrac{MS_E}{b}}$
$\sqrt{\dfrac{2 \cdot MS_E}{b}}$✔️
$\sqrt{MS_E}$
$\dfrac{MS_E}{b}$

Correct Answer Logic:

The standard error for comparing two treatment means in RCBD is $SE_{diff} = \sqrt{\dfrac{2 MS_E}{b}}$, where $b$ is the number of blocks (replications per treatment). Here $MS_E = 2.6249/24 = 0.1094$, so $SE_{diff} = \sqrt{2(0.1094)/9} \approx 0.1559$.

Question 8

A drink contains 20% mango juice and the rest is apple juice. What is the ratio of mango juice to apple juice?

$4 : 1$
$1 : 4$✔️
$1 : 20$
None of these

Correct Answer Logic:

If the drink contains 20% mango juice, then it contains 80% apple juice (100% - 20% = 80%). The ratio of mango to apple juice is $20 : 80 = 1 : 4$. This means for every 1 part mango juice, there are 4 parts apple juice.

Physics QUESTION #7038

Question 9

A screw gauge has a pitch of $0.5 \text{ mm}$ and $100$ circular divisions. When tightened without an object, the zero of the circular scale is $3$ divisions below the mean line. For a thin sheet, the readings are: Main Scale $= 5.5 \text{ mm}$, Circular Scale $= 48$. Find the sheet thickness.

$5.755 \text{ mm}$
$5.950 \text{ mm}$
$5.725 \text{ mm}$✔️
$5.740 \text{ mm}$

Correct Answer Logic:

$LC = \frac{0.5}{100} = 0.005 \text{ mm}$.

Zero Error: Since the zero is 3 divisions below the mean line, it is a positive zero error. Zero Error $= +3 \times 0.005 = +0.015 \text{ mm}$.

Observed Reading: $5.5 + (48 \times 0.005) = 5.5 + 0.240 = 5.740 \text{ mm}$.

Actual Thickness: Observed Reading $-$ Zero Error $= 5.740 - 0.015 = 5.725 \text{ mm}$.

Law QUESTION #9495

Question 10

A plaintiff institutes a suit for recovery of a loan on the basis of a promissory note. The defendant files a written statement but does not raise the defence of limitation. The Court frames issues but the defendant never raises limitation at trial. Can the Court, on its own motion, dismiss the suit on the ground that it is time-barred?

Yes; under the Limitation Act, every suit filed after the prescribed period is barred, and the Court must dismiss it regardless of whether it is pleaded, if the suit is apparently time-barred on the face of the plaint✔️
Yes; but only in appeals
No; limitation must be specifically pleaded by the defendant and the Court cannot raise it suo motu
No; a Court can only act on issues that are framed

Correct Answer Logic:

Section 3 of the Limitation Act 1908 imposes a mandatory obligation on every Court to dismiss a suit, appeal, or application that is prima facie time-barred, even if limitation has not been pleaded as a defence. The Court acts suo motu in such cases.

Law QUESTION #9472

Question 11

A obtained a decree against B in Civil Court Multan. B owns no property in Multan but has substantial moveable property in Karachi. A applies to the Multan Court to transfer the decree to the Civil Court Karachi for execution. B opposes, arguing A should file a fresh suit in Karachi. Which position is legally correct?

A is correct; the Multan Court may transfer the decree to the Civil Court Karachi on application by the decree-holder✔️
A should apply directly to the Karachi Court without routing through Multan
Transfer is only permissible if B consents
B is correct; a fresh suit is required to execute a decree in a different city

Correct Answer Logic:

Section 39 CPC empowers the Court which passed a decree to send it for execution to another Court if the judgment-debtor resides or has property within that other Court's jurisdiction. A separate suit is not required. The Multan Court has authority to transfer on A's application.

Physics QUESTION #7043

Question 12

Unpolarised light with intensity $I_0$ passes through polaroid A, then through polaroid B. If the transmission axis of B is at $45^\circ$ to A, find the final intensity.

$I_0$
$\frac{I_0}{2}$
$\frac{I_0}{4}$✔️
$\frac{I_0}{8}$

Correct Answer Logic:

After passing through polaroid A, the intensity becomes $I_1 = \frac{I_0}{2}$.

According to Malus's Law, after passing through polaroid B:

$I_2 = I_1 \cos^2 \theta = \frac{I_0}{2} \cos^2(45^\circ) = \frac{I_0}{2} \times \left( \frac{1}{\sqrt{2}} \right)^2 = \frac{I_0}{4}$.

Which of the following is true?

$\text{Na}^+$ is smaller than $\text{Na}$✔️
$\text{Cl}^-$ is less than $\text{Cl}$
$\text{Na}^+$ is greater than $\text{Na}$
