Key Points

• For an electric iron heater element should have higher resistance, high melting point, and high specific heat, using this information find the element mentioned in the option which will be suitable for an electric iron.
• copper, tungsten, nichrome, iron, platinum We know that the function of an electric iron is to remove wrinkles using pressure and heat.
• Since for using this machine for the long term, a heating element should not be melted.
• We know that there are two conditions under which an element gets melted.
• An element should have high resistance so that it can hold its configuration in a high voltage current.
• It should have a high melting point such that it can sustain high temperatures.
• So, from all the given Nichrome is used as a heating element in electric iron which is an alloy consisting 80% of Nickel and 20% of Chromium melting point of this element is 1400 degrees Celsius with high resistance which makes this element best for use as a heating element. Hence, Option 4 is correct.
• The reason which makes the Nichrome best for heating elements is when it is heated in the air it develops an outer layer of chromium oxide which makes it stable in air and this chromium layer helps the element from oxidizing further during heating.

Solar energy is converted into electrical energy by photovoltaic cells.

Photo voltaic cells:

• Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) cells or through mirrors that concentrate solar radiation.
• This energy can be used to generate electricity or be stored in batteries or thermal storage.
• A solar cell, or photovoltaic cell, is a semiconductor device that converts the energy of light directly into electricity by the photovoltaic effect.
• Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. 
• The photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel.

Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out.

Given:

The perpendicular drawn from point A (4, 1) divides the join of B (2, -1) and C (6, 5).

Concept used:

1. Straight Line equation using two points = 

2. If two straight lines are perpendicular, then their slopes are opposite reciprocals of one another, or the product of their slopes is −1.

3. If point R internally divides the line segment joining (x1, y1) and (x2, y2) in m : n ratio, then the coordinate of R is given by .

4. y = Mx + C (where M is the slope)

Calculation:

Equation of BC

⇒ 3x - 2y = 8      ....(1)

The slope of (1) = 3/2

The slope of the straight line that is perpendicular to (1) = (-1) div (3/2) = -2/3

Hence, the equation of the straight line that is perpendicular to (1)

⇒ y = (-2/3)x + K (K is a constant)      ....(2)

A (4, 1) is on (2). So, it must satisfy (2).

Hence,

1 = (-2/3) × 4 + K

⇒ K = 11/3

So, equation (2) becomes

⇒ y = (-2/3)x + 11/3 (Putting the value of K)

⇒ 2x + 3y = 11      ....(3)

By solving (1) and (3) we get,

x = 46/13 and y = 17/13

So, the intersecting point of (1) and (3) is H(46/13, 17/13). (Letting the (46/13, 17/13) to be H)

Hence, the foot of the perpendicular of A(4, 1) is (46/13, 17/13).

Let the point H divides BC in m : n ratio.

According to the concept,

⇒ m/n = 5/8

∴ The perpendicular drawn from point A (4, 1) divides the join of B (2, -1) and C (6, 5) in 5 : 8.

Given:
x² - 4x - 77 = 0
Solving the given quadratic equation by splitting the middle term,

Sum of the square of the roots = 11² + (-7)²

∴ The sum of the square of the roots is 170

Given:

Calculations:

According to question,

(17% + 19% + 16%) of 350

= 52% of 350

= 0.52 × 350

= 182

Hence, The Required value is 182.

Given:

By dividing the above equation by ;

By cubing both sides;

Given:

12 men complete the work in 8 days

First two days all 12 men do the work

On the third and fourth days 2 men did not report for work

Formula Used:

Total work = no. of men doing the work × number of days taken to complete the work

Total work = 12 men × 8 days

⇒ Total work = 96 units

According to question,

First two days all 12 men come to work

So, work completed by 12 men in 2 days

⇒ 12 × 2 = 24 units

Remaining work after 2 days = 96 - 24 = 72 units

According to question only 10 men worked for 2 days

Work done by 10 men in 2 days = 10 × 2 = 20 units

⇒ Remaining work = 72 - 20 = 52 units

Remaining work completed by 10 men in days = 5.2 days

∴ Total time taken = 2 days + 2 days + 5.2 days = 9.2 days

Given,
When positive numbers x, y and Z are divided by 31, the remainders are 17,24 and 27.
If a number (x) is divided by (a) leaves remainder (b), then x = ax n + b [where n is an integer]
Let the numbers be,
x = 31 x 1 + 17 = 48
y = 31 x 1 + 24 = 55
z=31x1+ 27 = 58
(4x-2y+3z) = 256
Now,
256 = 31 x 8 + 8
When (4x - 2y + 3z) is divided by 31, the remainder will be 8.

The correct answer is 'Option 2' i.e. 'The magazine will be published by the team next month.'

 Key Points

• The given question is in Future Simple Tense. The structure of the passive voice for Future Simple tense is: Will/Shall +be+ Past Participle form of the verb.
• The original sentence tells us that 'The team' will be doing the action (publish) in the future.
• The correct passive form will describe the action (publish) being done by the team (now 'by the team') to the magazine (now the subject).
• The correct passive form of the verb 'will publish' is 'will be published'.

Therefore, the correct answer is - 'The magazine will be published by the team next month.'

Additional Information

• Option 1 is incorrect because it uses the simple past tense, not future tense.
•  
• Option 3 is grammatically incorrect because 'will be published' is the correct form, not 'will be publish'.
• Option 4 is incorrect because it uses the past continuous tense, not future tense.

Correct Sentence: During his long discourse, he did not touch on that point.

There are some verbs/nouns/adjectives which are followed by fixed preposition given below:

• ​Exonerate from, refrain from, suspicious of, touch on, inured to, accused of, predilection for, respite from, vexed at, etc.
• For example: ​After spending some time on the island they became inured to the hardships.
• The phrasal verb 'touch on' means to briefly talk or write about (something).
• ​According to the rule and the example given above, 'touch on​' will be used in the underlined part of the sentence.

The correct pair of antonym is Barbaric - Civilised.

Barbaric: savagely cruel; exceedingly brutal.

• For example: The explorer was killed by the barbaric people that island.

Civilised: polite and well-mannered.

• For example:  I believe in a civilised political dialogue even if there are differences or ideological issues.

Thus, from the above-given explanation, it is clear that both 'Barbaric' and 'Civilised' are antonyms to each other.

If we go on to read the sentence further, it would indicate that the sentence is talking about the growth and dissemination of trade, commodities, and ideology of the empire with the empires in the east and west. It follows from logic that for this to happen, the Mongol empire needs to have relations with other empires in the east and the west. So, options A and C can clearly be eliminated since they convey the opposite meaning. Similarly, option D does not make any sense in the sentence. 'Connected' conveys the desired meaning in the context.

The given sentence talks about the fact that the empire disintegrated due to the struggle to claim the throne between his grandsons. This is known as the struggle for 'succession'.

The sentence is talking about commodities, technology, and ideology together. Therefore, we need a word that would fit in with all of these ideas. The sentence states that all of these were disseminated across the continent. Since the joining word used here is 'and', therefore, it can be inferred that the blank should contain a word that conveys a similar idea to that of 'dissemination'. Now, based on these criteria, options B and C can be eliminated, since ideology cannot be brought or sold. Option D can be ignored since it does not blend in grammatically with the sentence. Now, clearly, option A fits in best in the given context. 

Quell: put an end to (a rebellion or other disorder), typically by the use of force.

Repress: subdue (someone or something) by force.

Conceal: not allow to be seen; hide.

Exhale meaning: to breathe out.

And other words are the antonyms of Exhale.
