Chemistry QUESTION #7355

Question 1904

The total number of atomic orbitals present in the fourth principal energy level ($n = 4$) of an atom is:

8
16✔️
32
4

Correct Answer Logic:

Formula: Total orbitals in shell $n$ = $n^2$

For $n = 4$: $4^2 = 16$ orbitals

Breakdown:

4s: 1 orbital
4p: 3 orbitals
4d: 5 orbitals
4f: 7 orbitals
Total = 1+3+5+7 = 16

The two divisions of the autonomic nervous system are:

Voluntary and involuntary
Cerebrospinal and cortical
Thalamus and hypothalamus
Sympathetic and parasympathetic✔️

Question 1907

In 1968, US Congressman John Conyers introduced a bill to establish a national holiday in honor of Dr. Martin Luther King Jr. The bill didn't make it to a vote, but Conyers was determined. He teamed up with Shirley Chisholm, the first Black woman to be elected to Congress, and they resubmitted the bill every session for the next fifteen years. _______ in 1983, the bill passed. Which choice completes the text with the most logical transition?

Instead,
Likewise,
Finally,✔️
Additionally,

Correct Answer Logic:

'Finally' logically signals that the bill passing in 1983 was the concluding event after fifteen years of resubmission.

Law QUESTION #9489

Question 1908

A files a suit claiming ownership of a well-defined plot. The Court, after hearing both sides, finds in favour of A on all issues but inadvertently omits to grant consequential relief of mesne profits although it was claimed in the plaint. A applies for amendment of the decree. B argues the decree is final and cannot be amended. What should the Court do?

Refuse; a decree once passed is final and cannot be amended
Allow A's application; the Court has power under Section 152 to correct clerical or arithmetical mistakes and accidental omissions in decrees, and under the inherent powers of Section 151 in appropriate cases✔️
Direct A to file a fresh suit for mesne profits
Refer the matter to the High Court

Correct Answer Logic:

Section 152 CPC empowers the Court to correct clerical or arithmetical mistakes in judgments, decrees or orders, or errors arising from accidental slips or omissions. The inadvertent omission of a claimed relief that was argued falls within correctable error. Additionally, Section 151 preserves inherent powers to do justice.

Question 1914

Cats can judge unseen people's positions by voice. Researchers measured surprise via ear and head movements when cats heard owners' voices from one or two speakers. How did researchers determine cats' surprise level?

They watched ear and head movements.✔️
They examined reaction to a stranger's voice.
They studied physical interaction with owner.
They tracked how each cat moved around the room.

Correct Answer Logic:

The text explicitly states "measuring cats' levels of surprise based on their ear and head movements."

Journalism / Mass Communication QUESTION #6396

Question 1915

The Four-Step Public Relations process uses SWOT analysis in its first step. What does the acronym SWOT stand for?

Strategy, Weaknesses, Opportunities, Tactics
Strengths, Weaknesses, Opportunities, Threats✔️
Speed, Width, Outreach, Timing
Scope, Workforce, Output, Target

Correct Answer Logic:

SWOT Analysis stands for: Strengths, Weaknesses, Opportunities, Threats. It is a strategic planning tool used as part of the situational analysis in the first step of the PR process (“Defining PR Problems”). In the PR context:

Strengths: Internal positive factors — what the organisation does well
Weaknesses: Internal negative factors — areas of improvement needed
Opportunities: External positive factors — favourable trends or situations the organisation can exploit
Threats: External negative factors — risks from competitors, regulations, or public perception

The SWOT analysis is the diagnostic foundation of the PR campaign. Without understanding the current situation comprehensively, the subsequent strategy, implementation, and evaluation steps cannot be done effectively. SWOT was originally developed as a general business strategy tool and has been widely adopted across public relations, marketing, and management.

Physics QUESTION #7083

Question 1916

A solid sphere (radius $r$, bulk modulus $K$) is in a liquid. A mass $m$ is placed on a piston of area $a$ to compress the liquid. Find the fractional decrease in radius $\frac{dr}{r}$.

$\frac{mg}{3Ka}$✔️
$\frac{mg}{Ka}$
$\frac{Ka}{mg}$
$\frac{3Ka}{mg}$

Correct Answer Logic:

Bulk Modulus $K = \frac{\Delta P}{-\Delta V/V}$.

The change in pressure is $\Delta P = \frac{mg}{a}$.
The fractional change in volume for a sphere is $\frac{\Delta V}{V} = 3\frac{dr}{r}$.
$K = \frac{mg/a}{3dr/r} \implies \frac{dr}{r} = \frac{mg}{3Ka}$.

Question 1917

'Bagging' of a boiler shell occurs when:

The boiler is put in a bag
Localized overheating causes the metal to bulge outward due to internal pressure✔️
The boiler is painted
The operator makes a mistake

Correct Answer Logic:

This is often caused by oil or scale preventing heat transfer at that spot.

Physics QUESTION #1183

Question 1918

The charging and discharging behavior of an ideal RLC circuit is:

Simple harmonic✔️
Linear
Elliptical
Unpredictable

Correct Answer Logic:

In an ideal LC (or lightly damped RLC) circuit, the charge on the capacitor and current in the inductor oscillate sinusoidally — this is simple harmonic oscillation. The differential equation for an LC circuit is $L\frac{d^2q}{dt^2} + \frac{q}{C} = 0$, identical in form to the SHM equation $\ddot{x} + \omega^2 x = 0$.

Question 1919

In how many of the years shown was the average number of pages per newspaper at least twice as much as the average in 1940?

[Note: This refers to a graph showing average daily circulation for Newspaper X over years 1940-1980, with values: 1940: 30 pages, 1950: 55 pages, 1960: 82 pages, 1970: 70 pages, 1980: 74 pages]

Four
Three✔️
Two
One

Correct Answer Logic:

The average number of pages in 1940 was 30. Twice this amount is $2 \times 30 = 60$ pages.

Check each year:

1940: 30 pages (not $\geq 60$) ✗
1950: 55 pages (not $\geq 60$) ✗
1960: 82 pages ($\geq 60$) ✓
1970: 70 pages ($\geq 60$) ✓
1980: 74 pages ($\geq 60$) ✓

Three years (1960, 1970, and 1980) had at least twice the 1940 average.

Physics QUESTION #7079

Question 1920

Determine the pressure required at the ends of a steel wire (length $10\text{ cm}$) to maintain a constant length when the temperature is increased by $100^{\circ}\text{C}$. (Given: Steel Young's modulus $Y = 2 \times 10^{11}\text{ Nm}^{-2}$ and coefficient of thermal expansion $\alpha = 1.1 \times 10^{-5}\text{ K}^{-1}$)

$2.2 \times 10^{7}\text{ Pa}$
$2.2 \times 10^{6}\text{ Pa}$
$2.2 \times 10^{8}\text{ Pa}$✔️
$2.2 \times 10^{9}\text{ Pa}$

Correct Answer Logic:

The thermal stress required to keep the length constant is given by the formula:

$\text{Stress} = Y \alpha \Delta T$
Substituting the values: $\text{Stress} = (2 \times 10^{11}) \times (1.1 \times 10^{-5}) \times 100$
$\text{Stress} = 2.2 \times 10^{8}\text{ Pa}$

Pressure is equivalent to the stress applied at the ends.
