Key Points

In 1854, the first cotton mill was set up in Bombay and It grew as an important port for the export of raw cotton from India to England and China.

• This cotton crop became a huge demand and farmers started investing in it.
• Cotton turned the market upside down.
• A huge number of labours started working in mills.
• In Bombay, about 84 mills were established by Parsi and Gujarati businessmen by 1900.
• The construction and development of mills in cities started and the first mill in Ahmedabad was started in 1861.
• The growth of cotton mills demanded manpower.
• Poor peasants, artisans, and agricultural labourers started working in the mills.
• The textile industry of India faced problems such as difficulty competing with the cheap textiles imported from Britain.
• In most countries, the government-supported industrialization by applying and imposing heavy duties on imports which eliminated competition and protected infant industries.
• The first major spurt in the development of cotton factory production in India was during the First World War when textile imports from Britain were declined and Indian factories were called upon to produce cloth for military supplies.

The correct answer is ​Prohibition of employment of children in factories and mines.

Key Points

• RIGHT AGAINST EXPLOITATION : (Asked in UPSC Prelims 2017)
  • Prohibition of Traffic in Human Beings and Forced Labour
    • Article 23 prohibits traffic in human beings, begar (forced labour), and other similar forms of forced labour.
    • Any contravention of this provision shall be an offence punishable in accordance with the law.
    • This right is available to both citizens and non-citizens.
    • It protects the individual not only against the State but also against private persons.
    • The expression ‘traffic in human beings’ include
      • Selling and buying of men, women, and children like goods
      • Immoral traffic in women and children, including prostitution
      • Devadasis
      • Slavery.
    • To punish these acts, the Parliament has made the Immoral Traffic (Prevention) Act, 1956.
    • The term ‘begar’ means compulsory work without remuneration.
    • It was a peculiar Indian system under which the local zamindars sometimes used to force their tenants to render services without any payment.
    • In addition to begar, Article 23 prohibits other ‘similar forms of forced labor’ like ‘bonded labor’.
      • The term ‘forced labor’ means compelling a person to work against his will.
  • Prohibition of Employment of Children in Factories
    • Article 24 prohibits the employment of children below the age of 14 years in any factory, mine, or other hazardous activities like construction work or railway.
      • But it does not prohibit their employment in any harmless or innocent work.

⇒ 0.0023 + 0.024 + 0.025 + 0.26 × √k = 15.6513

⇒ 0.0513 + 0.26 × √k = 15.6513

⇒ 0.26 × √k = 15.6513 – 0.0513

⇒ 0.26 × √k = 15.6

⇒ √k = 15.6/0.26

⇒ √k = 60

⇒ k = (60)²

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C
So lightest in weight is C.

There are five such 5's as shown below

3 5 9 5 4 5 5 3 5 8 4 5 6 7 3 5 7 5 5 4 5 2 3 5 1 0

According to question,
A's weight is twice as much as of B.
1. A = 2B.
B's weight is four and half times as much as of C.
2. B = 4.5C
C's weight is half times as much as of D.
3. C = D/2.
D's weight is half as much as of E.
4. D = E/2.
E weight is less than A but more than C.
5. A > E > C
from 1 and 2
6. A = 2B = 9C
from 6 and 3
7. A = 2B = 9C = 4.5D
from 7 and 4
8. A = 2B = 9C = 4.5D = 2.25E
so from 8 and 5
A > B > E > D > C

So A is the heaviest in the weight.

The logic followed here is:

The place value of A is 1, D is 4, O is 15 and U is 21. 

In each of the given figure the alphabet and its place value are given except  U and 23 in figure D.

Hence, figure D is the odd one from the given figures.

According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A  (through these points by the shortest distance), he has to follow a path point A → B → F → E.

Thus travelling from point A, he will pass the first point B.

Hence, the correct answer is "Point B".

Hence, the person will be allowed to write a written test.

Microsoft Word or MS-WORD (often called Word) is a Graphical word processing program that users can type with. It is made by the computer company Microsoft. Its purpose is to allow users to type and save documents. It's an application software

School principal fulfils many roles and dealing with students' disruptive behaviour is among the least preferred by them. So, the teacher must try to discipline the students using various means like assigning responsibility to the undisciplined, finding out the underlying cause of his behaviour, and so on. Only after she has done everything without any effect on the student should she send the student to the principal.

Clearly, the force is time-dependent.  

Work required to turn the dipole is given by
W=MB[cosθ_i- cosθ_f]
Here θi is the initial angle made by a dipole with a magnetic field and   is the final angle made by a dipole with a magnetic field.
magnetic moment is normal to the field direction.
so, θ_i=0 and θ_f=90
W = 1.5 × 0.22 [ cos0° - cos90° ]
W = 0.33J
 
magnetic moment is opposite to the field direction.
so, θ_i=0 and θ_f=180
now, W = 1.5 × 0.22 [ cos0° - cos180°]
= 0.33 [ 1 - (-1) ]
= 0.66 J

In the direction of electric field the electric potential decreases. This is because electric potential is the work done against the direction of the electric field.

When a ball is thrown upwards, the vertical component of its velocity decreases as it rises because of the acceleration due to gravity (g), which acts downward.

• Gravity opposes the upward motion, reducing the ball's vertical velocity until it becomes zero at the highest point.
• After reaching the highest point, the ball starts descending, and the vertical velocity increases in the downward direction.

Thus, as the ball rises, the vertical component of its velocity decreases.

The  law states that the strain in a solid is proportional to the applied stress within the elastic limit of that solid body i.e. stress = k x strain.

Both the objects with different masses will attain the same v when striking the ground because acceleration and height is the same. 
As, K.E=(1​/2)mv²P.E=−GMm​p/r=mv
Thus K.E, P.E, and p will be different.
 

Long-sighted people who have lost their spectacles can still read a book by looking through a small (3-4 mm) hole in a sheet of paper because by doing so due to the diffraction at the hole the focal length of the eye lens is effectively decreased. Hence the correct option is C.
 

Initial velocity of car = 36 km/hr due north
Final velocity of car = 36 km/hr due west

The magnitude of change in velocity:

(since velocity is a vector, so direction has to be taken into account)

Acceleration = (Change in Velocity) / Time 

= [36(√2) * 5/18] / 5
= 2(√2) m/s² in South West

The frequency of radiation arising from the two close energy levels in hydrogen known as Lamb shift i.e. 1057 MHz is radio waves as it belongs to the short wavelength end of the electromagnetic spectrum. this wavelength correspond to microwave region of electromagnetic waves.

As the two identical coaxial circular loops carry a current i each circulating in the same direction, their flux add each other. When the two are brought closer, the total flux linkage increases. By Lenz's law a current will be induced in both the loops such that it opposes this change in flux. As the flux increases, the current in each loop will decrease so as to decrease the increasing flux.

An electric dipole is a separation of positive and negative charges. The simplest example of this is a pair of electric charges of equal magnitude but opposite sign, separated by some (usually small) distance. A permanent electric dipole is called an electret.

This is the question based on impulse momentum theorem.

A sentence having two past tenses is inappropriate (did and punished present in the same sentence). Thus, the first verb can be changed to the past perfect form to make the sentence grammatically suitable and correct. 'Although I had done my homework, the teacher punished me.'
Option 2 is thus correct.

Key Pointsसमास :- समास का तात्पर्य है ‘संक्षिप्तीकरण’।

दो या दो से अधिक शब्दों से मिलकर बने हुए एक नवीन एवं सार्थक शब्द को समास कहते हैं।

समस के भेद -

दिए गए विकल्पों में सही उत्तर विकल्प 3 ‘देशाटन’ है। अन्य विकल्प इसके अनुचित उत्तर हैं।

Key Points

• देशाटन का अर्थ होता है:- देश भ्रमण, पर्यटन करना।
• देशाटन का समास विग्रह:-
  • देश में अटन (भ्रमण)।
• अतः देशाटन शब्द तत्पुरुष समास का उदहारण है। क्योंकि यहाँ “का“ विभक्ति का लोप हुआ है। अतः सही उत्तर देशाटन होगा ।

अन्य विकल्प:-

Additional Information

• समास का तात्पर्य है ‘संक्षिप्तीकरण’। हिन्दी व्याकरण में समास का शाब्दिक अर्थ होता है छोटा रूप; जब दो या दो से अधिक शब्दों से मिलकर जो नया और छोटा शब्द बनता है उस शब्द को हिन्दी में समास कहते हैं।
• समास के उदाहरण:-
  • रसोई के लिए घर इसे हम रसोईघर भी कह सकते हैं।
  • राजा का पुत्र’ – राजपुत्र
• समास के निम्नलिखित छह भेद होते हैं—
• अव्ययीभाव समास - यदि एक शब्द की पुनरावृत्ति हो और दोनों शब्द मिलकर अव्यय की तरह प्रयोग हों वहाँ पर अव्ययीभाव समास होता है संस्कृत में उपसर्ग युक्त पद भी अव्ययीभाव समास ही मने जाते हैं।
• उदाहरण:-
  • प्रतिवर्ष =हर वर्ष
  • आजन्म = जन्म से लेकर
• तत्पुरुष समास - इस समास में दूसरा पद प्रधान होता है। यह कारक से जुदा समास होता है। इसमें ज्ञातव्य – विग्रह में जो कारक प्रकट होता है उसी कारक वाला वो समास होता है। इसे बनाने में दो पदों के बीच कारक चिन्हों का लोप हो जाता है उसे तत्पुरुष समास कहते हैं।
• उदाहरण:-
  • देश के लिए भक्ति = देशभक्ति
  • राजा का महल = राजमहल
• कर्मधारय समास - इस समास का उत्तर पद प्रधान होता है। इस समास में विशेषण -विशेष्य और उपमेय -उपमान से मिलकर बनते हैं उसे कर्मधारय समास कहते हैं।
• उदाहरण:-
  • पीताम्बर =पीत है जो अम्बर
  • महात्मा =महान है जो आत्मा
• द्विगु समास - द्विगु समास में पूर्वपद संख्यावाचक होता है और कभी-कभी उत्तरपद भी संख्यावाचक होता हुआ देखा जा सकता है। इस समास में प्रयुक्त संख्या किसी समूह को दर्शाती है किसी अर्थ को नहीं |इससे समूह और समाहार का बोध होता है। उसे द्विगु समास कहते हैं।
• उदाहरण:-
  • नवग्रह = नौ ग्रहों का समूह
  • दोपहर = दो पहरों का समाहार
• द्वन्द समास - इस समास में दोनों पद ही प्रधान होते हैं इसमें किसी भी पद का गौण नहीं होता है। ये दोनों पद एक-दूसरे पद के विलोम होते हैं लेकिन ये हमेशा नहीं होता है। इसका विग्रह करने पर और, अथवा, या, एवं का प्रयोग होता है उसे द्वंद्व समास कहते हैं।
• उदाहरण:-
  • जलवायु = जल और वायु
  • अपना-पराया = अपना या पराया
• बहुव्रीहि समास - इस समास में कोई भी पद प्रधान नहीं होता। जब दो पद मिलकर तीसरा पद बनाते हैं तब वह तीसरा पद प्रधान होता है। इसका विग्रह करने पर “वाला है, जो, जिसका, जिसकी, जिसके, वह” आदि आते हैं वह बहुब्रीहि समास कहलाता है।
• उदाहरण:-
  • गजानन = गज का आनन है जिसका (गणेश)
  • त्रिनेत्र =तीन नेत्र हैं जिसके (शिव)
