Psychology QUESTION #9729

According to the James-Lange Theory of emotion, which sequence correctly describes how emotions arise?

Stimulus → Emotion → Physiological response
Stimulus → Physiological response → Emotion✔️
Stimulus → Simultaneous emotion and physiological response
Stimulus → Cognitive appraisal → Emotion

Correct Answer Logic:

The James-Lange Theory proposes that emotions are the result of our perception of bodily (physiological) changes, not the cause. The sequence is: stimulus → physiological arousal → conscious emotional experience. For example, we feel afraid because we notice our heart racing, not the other way around. This theory is contrasted with the Cannon-Bard Theory, which argues that emotion and physiological response occur simultaneously.

Question 342

When using Grade 40 or Grade 50 steel reinforcement, the minimum steel ratio required by ACI 318 to control temperature and shrinkage cracking in slabs is:

0.10%
0.15%
0.18%
0.20%✔️

Correct Answer Logic:

Per ACI 318, for Grade 40 or 50 deformed bars, the minimum temperature and shrinkage steel ratio $\rho_{min} = 0.0020$ (i.e. 0.20%) of the gross cross-sectional area.

Journalism / Mass Communication QUESTION #6402

Question 343

In the context of media theory, the Libertarian Theory of the press is sometimes described as having a significant weakness. What is this weakness according to the textbook?

It gives governments too much power to control media content
Absolute freedom with no accountability leads to situations where all people have the right to speak and receive information freely, but no one takes responsibility for the wrong effects — ethics vary across multicultural societies, leading to constant complaints about each other's media✔️
Libertarianism requires too many government regulations to function
Libertarian media are too commercially focused to serve public interest

Correct Answer Logic:

The Libertarian Theory represents the polar opposite of Authoritarianism. Its strengths are compelling — competitive exposure of alternative viewpoints, media as a government watchdog, full editorial autonomy for journalists, no censorship, accountability only to law. However, the textbook identifies a key weakness: “Such an extensive freedom is also a problem as all people have the right to speak and receive information freely, but no one takes responsibility of the wrong doings. The ethics in multicultural or pluralistic societies vary from place to place; hence there is always complaint against the media of each other's society.” This weakness motivated the development of the Social Responsibility Theory, which retains press freedom but adds a framework of ethical obligation and self-regulation. Pure libertarianism struggles in pluralistic societies where different communities have different values and different ideas about what constitutes responsible communication.

Correct Answer Logic:

Option C gives standard basis for symmetric matrices. Option A has only 2 matrices (dimension 3 needed). Option B matrices are linearly dependent. Option D contains non-symmetric matrices.

Civil Procedure QUESTION #5667

Question 349

A defendant in a federal civil case fails to return a waiver of service requested by a plaintiff. The plaintiff then incurs $500 in costs to effectuate formal service. Under Rule 4(d)(2), what must the court do?

The court 'may' impose the costs if the defendant lacked 'good cause'.
The court 'must' impose the expenses of service and reasonable attorney's fees for the motion to collect, unless the defendant shows good cause.✔️
The court cannot impose costs if the defendant eventually prevails on the merits.
The court can only impose costs if the plaintiff proves the defendant acted in bad faith.

Correct Answer Logic:

Rule 4(d)(2) states that if a defendant located within the US fails, without good cause, to sign and return a waiver, the court 'must' impose the expenses later incurred in making service and reasonable expenses, including attorney's fees, of any motion required to collect.

Biology QUESTION #7277

Question 352

Which one is the wrong pairing for the disease and its causal organism?

Root-knot of vegetables — Meloidogyne sp.
Late blight of potato — Alternaria solani✔️
Black rust of wheat — Puccinia graminis
Loose smut of wheat — Ustilago nuda

Correct Answer Logic:

The wrongly matched pair is Late blight of potato — Alternaria solani. Late blight of potato is caused by Phytophthora infestans (an oomycete), not Alternaria solani. Alternaria solani causes early blight of potato. The other pairings are correct: Meloidogyne causes root-knot, Puccinia graminis causes black rust, Ustilago nuda causes loose smut.

Physics QUESTION #1172

Question 354

A charge moving in a uniform static magnetic field experiences:

A force perpendicular to magnetic field and velocity✔️
Increase in momentum
Decrease in momentum
Decrease in velocity

Correct Answer Logic:

The magnetic force on a moving charge is given by the Lorentz force: $\vec{F} = q(\vec{v} \times \vec{B})$. The cross product means the force is always perpendicular to both the velocity $\vec{v}$ and the magnetic field $\vec{B}$. Since the force is perpendicular to velocity, it does no work, so speed (and hence momentum magnitude and kinetic energy) remains unchanged.

Mathematics QUESTION #979

Question 355

The sum of all values of $\theta\in[0,2\pi]$ satisfying $2\sin^2\theta=\cos 2\theta$ and $2\cos^2\theta=3\sin\theta$ is:

$4\pi$
$\dfrac{5\pi}{6}$
$\pi$✔️
$\dfrac{\pi}{2}$

Correct Answer Logic:

From $2\sin^2\theta=\cos2\theta=1-2\sin^2\theta \Rightarrow 4\sin^2\theta=1 \Rightarrow \sin\theta=\pm\frac{1}{2}$. From $2\cos^2\theta=3\sin\theta \Rightarrow 2(1-\sin^2\theta)=3\sin\theta \Rightarrow 2\sin^2\theta+3\sin\theta-2=0 \Rightarrow \sin\theta=\frac{1}{2}$ (taking positive root). So $\theta=\frac{\pi}{6}$ or $\frac{5\pi}{6}$. Sum$=\frac{\pi}{6}+\frac{5\pi}{6}=\pi$.

Question 357

A buyer and seller agree on the sale of a unique antique vase for $\text{\$50,000}$. Before delivery, the vase is destroyed in a fire through no fault of the seller. What is the status of the contract?

The seller must find an identical vase or pay damages.
The contract is discharged by impossibility/frustration of purpose.✔️
The buyer must still pay the $\text{\$50,000}$ because risk of loss passed at the time of the contract.
The seller is in breach for failure to deliver.

Correct Answer Logic:

Under the doctrine of impossibility (or impracticability), if the subject matter of the contract is destroyed without the fault of either party, the duties under the contract are discharged.

Mathematics QUESTION #6980

Question 358

A box holds 15 green and 10 yellow balls. If 10 balls are picked one at a time with replacement, find the variance of the number of green balls picked.

$\dfrac{12}{5}$✔️
6
4
$\dfrac{6}{25}$

Correct Answer Logic:

This is a binomial experiment: $n=10$, $p=P(\text{green})=\dfrac{15}{25}=\dfrac{3}{5}$, $q=\dfrac{2}{5}$.

$\text{Variance} = npq = 10 \times \dfrac{3}{5} \times \dfrac{2}{5} = 10 \times \dfrac{6}{25} = \dfrac{60}{25} = \dfrac{12}{5}$

Maths QUESTION #2819

Question 359

Divide Rs. 4500 among A, B, and C in the ratio $3:4:5$.

A=Rs.900 B=Rs.1200 C=Rs.1500
A=Rs.1000 B=Rs.1500 C=Rs.2000
A=Rs.1125 B=Rs.1500 C=Rs.1875✔️
A=Rs.1200 B=Rs.1500 C=Rs.1800

Correct Answer Logic:

Total parts $= 3 + 4 + 5 = 12$. A $= \dfrac{3}{12} \times 4500 = 1125$, B $= \dfrac{4}{12} \times 4500 = 1500$, C $= \dfrac{5}{12} \times 4500 = 1875$.

Physics QUESTION #1176

Question 360

The Zeeman effect is due to the interaction of:

External magnetic field and total magnetic field of the specimen✔️
External electric field and magnetic field of specimen
L, S coupling
None of these

Correct Answer Logic:

The Zeeman effect is the splitting of spectral lines when an atom is placed in an external magnetic field. It arises due to the interaction between the externally applied magnetic field and the total magnetic moment (orbital + spin) of the atom. The energy levels split according to $\Delta E = m_l \mu_B B$.
