At 11 am on 9 December 1946 the Assembly began its first session, with 211 members attending. By early 1947, representatives of the Muslim League and princely states joined, and the Assembly approved the draft constitution on 26 November 1949.

Since its independence in 1930, in Mexico elections are held after 6 years to elect its president but till 2000 every election was won by PRI (Institutional Revolutionary Party). No opposition party won the elections because PRI used many dirty tricks to win the elections. All the government employs had to attend all the govt. meetings teachers were supposed to suppress the parents to vote PRI. PRI also controlled the media. 
Thus, we cannot say this type of system a democracy, at last we conclude that Mexico couldn't be called a democracy till 2000.

The correct answer is wood.

Concept:

Segregation of Waste: Waste Can be segregated as

• Bio-Degradable Waste: 
  • Waste that can be decomposed by microorganisms. 
  • It includes organic waste, e.g. kitchen waste, vegetables, fruits, flowers, leaves, wood, and paper.​
• Non-Bio Degradable Waste:
  • ​Waste that cannot be decomposed by microorganisms.
  • It includes plastic, rubber, glass, electronic waste, etc. 

Explanation:

Non-Biodegradables can be disposed of by following the 3Rs: 

• Reduce: If the old objects (bags, water bottles, clothes) are in good condition, it's better to keep using them rather than buying new things. 
• Reuse: Jam or pickle jars or plastic bottles can be used again to store small objects like buttons. 
• Recycle: Paper, glass, some plastics, and metals can be recycled. 

Wood is biodegradable, it can be made into compost but cannot be recycled. 

• The heat is transferred in form of conduction, convection, and radiation. 
• Radiation is the mode of heat transfer that does not require a medium. It happens through infrared radiation. 
• The infrared radiations are electromagnetic waves having a frequency less than the visible spectrum. 
• The infrared radiation is emitted from every hot body. 
• Earth is heated by infrared radiations of the sun. The radiations are reflected back by the earth which is captured by greenhouse gases. 
• The greenhouse gases absorbers some amount of heat and keeps the earth warm. 

Thus, infrared radiation is trapped on the earth’s surface by the greenhouse effect.

Additional Information

• The major Greenhouse gas is Carbon dioxide followed by methane, water vapor, and nitrous oxide.  
• UV rays have a frequency higher than violet and they help in the formation of Ozone. 
• The wavelength of different electromagnetic waves are given in the below diagram. 

Void ratio (e): 

• Void ratio is usually defined as the ratio of the volume of voids to the total volume of soil solid.

Porosity (n): 

• Porosity is defined as the ratio of the volume of voids to the total volume of the soil.

The relationship between void ratio and porosity are as follows:

The cofficient of price elastcity of demand is always negative which shows the inverse relationship between price and demand of a commodity if one of them increases the other decreases

Wages represent the compensation or payment received by individuals for their labor or work input in the production process. It is the reward for the physical or mental effort exerted by workers.

An agent's preferences are said to be stronglymonotonic if, given a consumption bundle , the agent prefers all consumption bundles that have more of at least one good, and not less in any other good.

Asif Ali Zardari was sworn in as Pakistan's 14th President, replacing Dr Arif Alvi. The oath was administered by Chief Justice of Pakistan Qazi Faez Isa at Aiwan-e-Sadr, the Presidential Palace. Zardari, aged 68, is associated with the Pakistan Peoples Party.

The correct answer is:

d) Between F and 2F

Explanation:

A convex lens forms a magnified real image when the object is placed between the focal point (F) and twice the focal length (2F).

Key Points:

• Real image: Formed when light rays actually converge (can be projected on a screen).

• Magnified: The image is larger than the object.

• Positioning:

  • If the object is at F, no image forms (rays become parallel).

  • If the object is at infinity, the image forms at F (diminished and real).

  • If the object is at 2F, the image is same size and real (not magnified).

  • Between F and 2F: Image is real, inverted, and magnified.

Final Answer:

d) Between F and 2F

In 1864, Newlands arranged the known 56 elements in the order of increasing atomic masses. He observed that the properties of every eighth element are similar to the properties of the first element. Based on this observation, he proposed the Law of Octaves for the classification of elements. Law of Octaves: When the elements are arranged in the increasing order of their atomic masses, the properties of every eighth element are similar to the first.

Light travels from rarer to denser medium when it enters into earth's atmosphere

It is a bright yellow odourless crystalline solid, that becomes orange and red when heated. It was formerly called plumbous iodide.

​​​​​​​So Option D is correct

Let AB be the wall and BC be the ladder.

Then, ACB = 60º and AC = 4.6 m.

⇒ BC = 2 x AC
= (2 x 4.6) m
= 9.2 m.

The correct chronological order of the following famous Ancient Indian astronomers and mathematicians is:

I. Aryabhatta

II. Varahamihira

III. Brahmagupta

IV. Bhaskara

The chronological order of these astronomers and mathematicians can be determined based on the time periods in which they lived and made significant contributions to their respective fields.

• Aryabhatta: Aryabhatta was an ancient Indian mathematician and astronomer who lived during the 5th century. He is known for his work on mathematics, including the concept of zero and the decimal system.


• Varahamihira: Varahamihira was an Indian astronomer and mathematician who lived during the 6th century. He made significant contributions to the field of astronomy, including the calculation of planetary positions and the prediction of eclipses.


• Brahmagupta: Brahmagupta was an Indian mathematician and astronomer who lived during the 7th century. He is known for his work on mathematics, including the development of algebra and the study of quadratic equations.


• Bhaskara: Bhaskara was an Indian mathematician and astronomer who lived during the 12th century. He made significant contributions to both mathematics and astronomy, including the development of trigonometry and the study of planetary motion.

Therefore, the correct chronological order of these famous Ancient Indian astronomers and mathematicians is I. Aryabhatta, II. Varahamihira, III. Brahmagupta, IV. Bhaskara.

Option A: I, II, III, IV is the correct answer.

After Balban's death in 1287, Delhi's kotwal Malik al-Umara Fakhruddin enthroned Balban's teenage grandson Muiz ud din Qaiqabad (or Kayqubad) with the title Muizzuddin. Qaiqabad was a weak ruler, and the administration was actually run by his officer Malik Nizamuddin. After Nizamuddin was poisoned by some rival officers, Qaiqabad summoned Jalal-ud-din from Samana to Delhi, gave him the title "Shaista Khan", appointed him as the ariz-i-mumalik, and made him the governor of Baran.

By this time, Qaiqabad's health had deteriorated, and two rival factions of nobles vied for the power in Delhi. One faction, led by Malik Aytemur Surkha, sought to maintain the power of the old Turkic nobility, and wanted to retain Balban's family on the throne. The other faction, led by Jalal-ud-din, supported the rise of the new nobility

Vijayanagara was the capital city of the historic Vijayanagara Empire which is located on the banks of the Tungabhadra River. It spread over a large area and included the modern era Group of Monuments at Hampi site in Ballari district and others in and around that district in Karnataka, India.

The correct option is B.
Between the years 1870 and 1880, Indian people had become politically conscious and by the year 1885, there was a platform ready for establishment of a political organization on a national basis. The credit for giving a definite structure to the all India organization goes to a retired British officer A.O. Hume. He was a liberal minded person. Hume had been feeling a need for a political organization which would bridge the gap between the rulers and the people being ruled. Hume wanted the people to adopt the path of valid politics instead of violence and aggression. With the efforts of Mr. Hume, "Indian National Union" was formed.
Hume obtained the permission from Lord Dafrin to convene a meeting of "Indian national Union" between 25th December and 313st December in Pune. The objective of the meeting was to acquaint the work force with one another, which was working for the national development and define a political agenda for the development.
Although the place of convention was decided to be Pune, the venue was changed to Mumbai in the last minute. The convention was held at Mumbai on 28th December 1885 in Gokuldas Tejpal Sanskrit College. At the suggestion of Sir Hume the meeting was named "Indian national Congress" and thus, Indian National Congress was born. There were 72 representatives in this convention of the Indian National Congress. Vyomesh Chandra Benarjee was the president of the first convention of Indian National Congress.
The Objectives of establishment of Indian National Congress- Historians believe that, with the direction from British Government Huma and his colleagues had founded Indian National Congress as a protective shield for British Government. Hume did not want the people of India to adopt violent and aggressive measures to register their discontent and anger against British Rule. Hume wanted to encourage people to take a legitimate path of protest like-appeals, memorandum, delegations to influence the British Government, in order to fulfil the demands.
The leaders of Congress accepted the leadership of A.O. Hume in the foundation of Indian National Congress because they were not in the position of having an open conflict with the British Government in the existing circumstances. This was more sensible to cooperate with Hume, in order to have a common platform wherein they could discuss the problems of the country.

Current is defined as the amount of electric charge flowing through a cross-section of circuits in unit time.
I = Q/T

In this analogy, subtract the position number of each alphabet from 26.
M ⇒ 26 - 13 = 13
O ⇒ 26 - 15 = 11
⇒ MO : 13 11
Similarly,
H ⇒ 26 - 8 = 18
J ⇒ 26 - 10 = 16
So, right answer is 18 16

The logic is x³ : (x+1)³ + 1
                   2³ : (2 + 1)³ + 1
                   2³ : 3³ + 1
                   8  :  28
27 = 3³
so next digit (n+1)³ + 1 = (3 + 1)³ + 1 = 64 + 1 = 65
