1.Helium is created deep in the earth from the radioactive decay of uranium and thorium (which also gives the earth its internal heat), and is "mined" from natural gasand oil wells (it comes up with the natural gas and is separated and stored). It's also constantly seeping up from the ground all around us, but it is so light that almost all of it escapes into space fairly rapidly.
2. Neon is used in signs and light bulbs and creates a very bright light when electricity is introduced to it.
3. Argon is the most common and cheapest of the noble gases. It can be extracted from air by cooling the air down to the point where it liquefies, then doing a fractional distillation of the resulting liquid to isolate the argon fraction. Most household incandescent light bulbs are filled with argon.
4.Krypton is used in higher grade light bulbs and is also put in between some panes of glass in energy efficient double-pane windows.
5.Strobe lights and camera flashes are commonly made using Xenon.
6. Radon gas is radioactive, and it seeps out of the ground all over the world collecting in basements and causing lung cancer. It is generated by the radioactive decay of thorium, of which there is a lot in the earth's crust. You can install special fans and venting systems to remove the radon from your house, which may be a good idea if the levels in your geographical area are unusually high.
Fundamental Rights are contained in Part III— called "Magna Carta” of theConstitution. The idea was borrowed from USA. Initially there were 7 fundamental rights, now there are only 6. (The Right to Property was deleted by the 44th amendment in 1978. It is now a judicial right—it has been moved to Article 300(A).)
The Supreme Court judgement in Keshwanand Bharti vs Kerala case provided that Fundamental Rights can be altered by the Parliament as long as the basic structure of the Constitution remains intact.
The Minerva Mills case ruling of the Supreme Court, however, ruled that Fundamental rights are basic part of the Constitution. The power to alter them was snatched away.
Fundamental Right of Equality provides for:
—Equality in government jobs (Article 16).
—No discriminations (Article 15).
—No untouchability (Article 17).
—Abolition of titles (Article 18).
The important freedoms granted are:
—Against exploitation (Article 23).
—Against child labour (Article 24).
The Right to Constitutional Remedies is provided under Article 32.
Habeas Corpus—"may I have the body”—it orders to present reasons as well as physical presence of a body in court, within 24 hours of arrest. Mandamus—issued to person, office or court—to enforce duties—also called "Param Aadesh”.
Prohibition—issued to inferior courts, by superior courts—it prohibits (stops) action of acts outside their jurisdiction.
Quo Warranto—it asks how one has gained unauthorised office.
Certiorari —Higher Court takes over case from lower courts.
Dr Ambedkar has called this article as "soul” of the Constitution.

What were the points of conflict between the moderates and extremist in the Indian National Congress during the initial stages of the nationalist movement? Methods of which of the two ideologies ultimately guided the nationalist movement in the later years?
Formation of the Indian National Congress in 1885 was the fist organized step to manifest the need for a nationalist movement. The initial years of the Congress were marked by the learning of the democratic methods. Till the beginning of the twentieth century, the methods of the nationalist leaders continued to be highly democratic and respectful in nature. These methods evolved under the bonafide belief of the leaders that the British government was responsive towards various needs and suggestions of the people of India and were willing to make certain changes as requested by them from time to time.
But, gradually the people began to get disillusioned with this method of nationalism. It was realized that on most of the issues the British government adopted dilatory tactics and avoided taking any decisions. Most of the petitions ultimately bore no results. The Congress leaders who still believed in these methods were referred to as the moderate leaders.
The moderates failed to produce any results and most of the moderate leaders like Surendranath Banerjea and Gopal Krishan Gokhale failed to lead the masses and could not force the British government to take any steps towards the welfare of the people of the country. Within the Congress, certain new generation leaders like Lala Lajpat Rai, Bipin Chander Pal and Bal Gangadhar Tilak began to disagree with the methods of the moderate leaders and formed a new faction with the Congress which wanted to deviate from the traditional methods of written protests and petitions and wanted direct action in the form of agitations and strong physical protests. This group of the nationalist was not satisfied with the demand for dominion status and wanted complete independence from the British rule. These leaders came to be known as the extremists.
Gradually, the people could gauge the fruitlessness of the moderates. The extremist Congress leaders with their ideal of ousting the British from India, could get more support from the masses and the moderate leaders gradually disappeared into oblivion and irrelevance. The newly found confidence of the extremist leaders was accentuated by the advent of Gandhiji on the Indian nationalist scene.
With his firm belief in truth and non-violence, Gandhiji emerged as a leader of the masses. The ideology and methods of the extremist leaders got a fillip and resurrected nationalist movement caught the fancy of the masses. With appropriate direction to the movement, efficient leadership and plethora of movements and agitations, the masses not only got involved in the nationalist movement but also believed that it was only the aggressive and non-violent policy of agitation that could result in ultimate independence for the country.
one off topic question, that I am posting here, because I think most of this threads followers are engineers, recently ONGC has came up with the recruitment notification. There they asked for Computer engineers, I am a BTECH in IT, so am I eligible?as in most cases CSE/IT are considered equivalent.

Mechanical Waves act as the propagation of a disturbance through a material medium due to the repeated periodic motion of the particles of the medium about their mean positions, the disturbance being handed over from one particle to the next. Electromagnetic Waves are the disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Matter Waves are the waves produced in electrons and particles.
Mechanical waves are of two types:
Transverse Wave
Longitudinal Wave.
I think majority would be knowing about these waves .For electromagnetic waves the existence of medium is not essential for propagation. The Periodic changes takes place in electric and magnetic fields hence it is called Electromagnetic Wave.
Properties:
In vacuum E.M waves travel with light velocity.
E.M waves can be polarized.
E.M waves are transverse in nature.
Medium is not required for propagating the E.M waves.
E.M waves have momentum.
Matter waves are called De Broglie waves .
They show or depict that everything in the world has i.e. every matter has wave like nature.It is named so because De Broglie equations are basically equations that suggest the dual nature of matter.
Which of the following is not a fertilizer product -
0 answers 1) Urea
1 answer 2) Murate of Potash
0 answers 3) Di Amonium Phosphate
13 answers 4) Calcium Carbonate
2 answers 5) All are fertilizers
Ä‚—
we know Urea and Diammonium phosphate are fertilisers so lets focus on other two
Potassium chloride was historically known as "muriate" of potash and is used as a fertliser regarding calcium carbonate we know its a strong base hence it is used to reduce the acidity in soil and water. It can be spread over the ground before planting and as an alkali, it works to bring acidity in the soil down to create move favorable conditions for growing plants.
