Mathematics QUESTION #978

Question 11262

Let $\alpha_\theta$ and $\beta_\theta$ be the distinct roots of $2x^2+(\cos\theta)x-1=0,\ \theta\in(0,2\pi)$. If $m$ and $M$ are the minimum and maximum values of $\alpha_\theta^4+\beta_\theta^4$, then $16(M+m)$ equals:

24
25✔️
17
27

Correct Answer Logic:

By Vieta's: $\alpha+\beta=-\frac{\cos\theta}{2}$, $\alpha\beta=-\frac{1}{2}$. Then $\alpha^2+\beta^2=(\alpha+\beta)^2-2\alpha\beta=\frac{\cos^2\theta}{4}+1$. And $\alpha^4+\beta^4=(\alpha^2+\beta^2)^2-2(\alpha\beta)^2=\left(\frac{\cos^2\theta}{4}+1\right)^2-\frac{1}{2}$. Let $u=\cos^2\theta\in[0,1]$. Max at $u=1$: $M=\frac{25}{16}-\frac{1}{2}=\frac{17}{16}$. Min at $u=0$: $m=1-\frac{1}{2}=\frac{1}{2}$. So $16(M+m)=16\cdot\frac{25}{16}=25$.

Electronics Engineering QUESTION #11739

Question 11265

A frequency counter displays $1.000\,003\,\text{MHz}$ for a $1\,\text{MHz}$ reference signal. The measurement error in ppm is:

$3\,\text{ppm}$✔️
$0.3\,\text{ppm}$
$30\,\text{ppm}$
$0.003\,\text{ppm}$

Correct Answer Logic:

Error $= \dfrac{|f_{measured} - f_{actual}|}{f_{actual}} \times 10^6 = \dfrac{1.000003 - 1.000000}{1.000000} \times 10^6 = 3 \times 10^{-6} \times 10^6 = \mathbf{3\,\text{ppm}}$. This ppm (parts per million) figure characterises oscillator and counter accuracy. TCXO stability is typically 0.5–2.5 ppm; OCXO provides < 0.01 ppm.

Dairy Food Science and Technology QUESTION #6000

Question 11266

The $Z$-value in thermal processing refers to:

The decimal reduction time at a given temperature
The temperature change required to produce a $10$-fold ($1$ log cycle) change in $D$-value✔️
The total number of logs of microbial reduction achieved
The activation energy of the spoilage reaction

Correct Answer Logic:

$Z$-value is the temperature increase ($^{\circ}\text{C}$ or $^{\circ}\text{F}$) required to reduce the $D$-value by a factor of $10$ (1 log cycle). For $C.\;botulinum$ spores, $z = 10^{\circ}\text{C}$ ($18^{\circ}\text{F}$). $Z$-value is used to calculate equivalent thermal processes: $F_T = D_T \times \log\left(\frac{N_0}{N}\right)$.

Agronomy QUESTION #2017

Question 11269

Primary tillage differs from secondary tillage in that primary tillage:

Is performed closer to sowing time with lighter implements
Breaks the soil to greater depths and is performed soon after harvest of the previous crop✔️
Is exclusively used for inter-row cultivation during crop growth
Involves only the surface 2–3 cm of soil

Correct Answer Logic:

Primary tillage refers to deep initial tillage (e.g., moldboard or disc plowing) performed after harvest to break up compacted soil. Secondary tillage involves shallower, finer operations (harrowing, leveling) performed closer to sowing to refine the seedbed.

Boilers Mechanical Engineering QUESTION #2526

Question 11270

A particle moves in a straight line with constant acceleration $a$. Starting from rest ($v_0=0$), the distance traveled in time $t$ is:

$s = at$
$s = \frac{1}{2}at^2$✔️
$s = \frac{at^2}{4}$
$s = 2at^2$

Correct Answer Logic:

For constant acceleration with $v_0=0$: integrating $a=\text{const}$ gives $v=at$, and integrating again gives $s=\frac{1}{2}at^2$.

Physics QUESTION #7022

Question 11272

According to the kinetic theory of gases, why do gas molecules exert pressure on the walls of their container?

They undergo a change in momentum when hitting the walls.✔️
They continuously stick to the walls.
They lose energy until they reach the wall.
They are attracted by the forces of the walls.

Correct Answer Logic:

Pressure is defined as force per unit area. Force is the rate of change of momentum. When molecules collide elastically with the walls, their direction changes, resulting in a change in momentum which exerts a force on the wall.

Mathematics QUESTION #6974

Question 11274

Find the value of $\displaystyle\int_{-\pi/2}^{\pi/2}\dfrac{\sin^2 x}{1+2^x}\,dx$

$4\pi$
$\dfrac{\pi}{4}$✔️
$\dfrac{\pi}{8}$
$\dfrac{\pi}{2}$

Correct Answer Logic:

Let $I=\displaystyle\int_{-\pi/2}^{\pi/2}\dfrac{\sin^2x}{1+2^x}dx$. Use the property $\int_{-a}^a f(x)dx$: replace $x\to-x$:

$I=\displaystyle\int_{-\pi/2}^{\pi/2}\dfrac{\sin^2x}{1+2^{-x}}dx=\displaystyle\int_{-\pi/2}^{\pi/2}\dfrac{2^x\sin^2x}{1+2^x}dx$

Adding: $2I=\displaystyle\int_{-\pi/2}^{\pi/2}\sin^2x\,dx=\displaystyle\int_{-\pi/2}^{\pi/2}\dfrac{1-\cos2x}{2}dx=\dfrac{\pi}{2}$

$I=\dfrac{\pi}{4}$

Administration QUESTION #9574

Question 11276

The 'Government of India Act 1935' introduced two significant provisions relevant to Pakistan's current administrative structure. What were these provisions, and how did they shape the post-independence civil service?

It introduced the provincial civil service and created the post of Governor General — both were retained after independence with minor modifications
It provided security of tenure for civil servants (no dismissal without hearing/right of appeal) and gave the provinces financial autonomy — establishing the principle of civil servant protection that was later codified in Pakistan's Civil Servants Act 1973✔️
It created the Federal Public Service Commission and the first competitive examination system for entry to the Indian Civil Service — the structural predecessor of Pakistan's FPSC
It established the first merit-based promotion system and abolished seniority-based advancement — a principle reversed by subsequent Pakistani governments

Correct Answer Logic:

The Government of India Act 1935 introduced two landmark protections: security of tenure (no dismissal without due process, including right of appeal up to Secretary of State) and provincial financial autonomy. The security of tenure principle became foundational to civil service independence in Pakistan — codified in the Civil Servants Act 1973 — while provincial financial autonomy laid conceptual groundwork for federalism and NFC-type resource-sharing mechanisms.

Civil Procedure QUESTION #5666

Question 11278

A plaintiff moves for summary judgment under Rule 56. The defendant opposes the motion with an affidavit from a witness that contains hearsay. The plaintiff does not object to the affidavit. The court grants summary judgment. On appeal, can the plaintiff raise the hearsay objection for the first time?

Yes, because hearsay is inherently unreliable and the court should have excluded it sua sponte.
No, because a party must object to the admissibility of evidence in a summary judgment motion to preserve the issue for appeal.✔️
Yes, because Rule 56 requires 'admissible' evidence, and hearsay is not admissible.
No, because summary judgment rulings are reviewed de novo and the appellate court will ignore the hearsay anyway.

Correct Answer Logic:

Generally, evidentiary objections not raised in the trial court are waived. In the context of summary judgment, if a party fails to move to strike or otherwise object to an affidavit, the objection is usually waived.
