Mathematics QUESTION #1267

Question 4584

Changing the order of integration in $\displaystyle\int_0^2\int_0^{\sqrt{x}}f(x,y)\,dy\,dx$ gives:

$\displaystyle\int_0^{\sqrt{2}}\int_0^{y^2}f(x,y)\,dx\,dy$
$\displaystyle\int_0^{2}\int_0^{y^2}f(x,y)\,dx\,dy$
$\displaystyle\int_0^{\sqrt{2}}\int_{y^2}^{2}f(x,y)\,dx\,dy$✔️
$\displaystyle\int_0^{2}\int_{\sqrt{x}}^{2}f(x,y)\,dx\,dy$

Correct Answer Logic:

Original region: $0\leq x\leq 2$, $0\leq y\leq\sqrt{x}$. Equivalently: $y$ ranges from $0$ to $\sqrt{2}$; for fixed $y$, $x$ ranges from $y^2$ to $2$ (since $y\leq\sqrt{x}\Rightarrow x\geq y^2$). So: $\int_0^{\sqrt{2}}\int_{y^2}^{2}f(x,y)\,dx\,dy$.

Question 4585

The Tourism Management course covers 'managing urban tourism.' Which of the following is identified as a key challenge specific to urban tourism management?

The Constitution of Pakistan QUESTION #9399

Question 4589

All elected members
Muslim members only✔️
Members who have taken oath
All members including those elected on reserved seats

Correct Answer Logic:

Article 91(3) specifies: 'the National Assembly shall, to the exclusion of any other business, proceed to elect without debate one of its Muslim members to be the Prime Minister.' The requirement that the PM be a Muslim is a constitutional qualification distinct from ordinary membership qualifications — a non-Muslim cannot be PM regardless of other credentials.

Boilers Mechanical Engineering QUESTION #2440

Question 4596

The logarithmic decrement $\delta$ is used to experimentally measure damping. It is defined as:

$\delta = \ln\frac{x(t)}{x(t+T_d)} = \frac{2\pi\alpha}{\omega_d} = \frac{2\pi\zeta}{\sqrt{1-\zeta^2}}$✔️
$\delta = \frac{x(t+T_d)}{x(t)}$
$\delta = \frac{\omega_d}{\alpha}$
$\delta = \frac{c}{2m}$

Correct Answer Logic:

Logarithmic decrement: $\delta=\ln\frac{x(t)}{x(t+T_d)}=\frac{2\pi\alpha}{\omega_d}=\frac{2\pi\zeta}{\sqrt{1-\zeta^2}}$. It allows $\zeta$ to be determined from experiment.

Agronomy QUESTION #2067

Question 4600

In an additive intercropping system, the total plant population of each component crop compared to its sole crop population is:

Reduced by 50% for each component crop
Maintained at the full sole crop density for each component — extra land area is effectively 'added' to accommodate both crops, unlike replacement series where populations are reduced✔️
Determined only by the LER value of the previous season
Equalized between the two component crops regardless of their sole crop densities

Correct Answer Logic:

In additive intercropping, one crop (main crop) is maintained at its full sole crop density and the intercrop (sub-crop) is added into the existing arrangement — no reduction in either component's population relative to sole cropping. This contrasts with replacement (substitutive) intercropping, where populations are proportionally reduced. Additive systems maximize total productivity.
