Carbon exists in various forms called allotropes. Which of the following is not an allotrope of carbon?

Correct Answer: soot
(B) Soot is not a pure form of carbon. It is residue from incomplete combustion. Soot contains many organic compounds and inorganic compounds in addition to fine particles of graphite. The composition of soot varies with the distance from the flame that produced it.

Combined carbon content in iron and steel is determined by treating the sample with dilute HNO3. So that combined carbon forms a soluble brown nitrated compound, the intensity of which is matched with that of a standard sample of similar composition treated under similar condition. The intensity of color produced is proportional to the carbon content of iron of steel sample. This method of combined carbon determination is called the

Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.

What is Gandhian philosophy? It is the religious and social ideas adopted and developed by Gandhi, first during his period in South Africa from 1893 to 1914, and later of course in India. These ideas have been further developed by later "Gandhians", most notably, in India by, Vinoba Bhave and Jayaprakash Narayan. Outside of India some of the work of, for example, Martin Luther King Jr. can also be viewed in this light. Understanding the universe to be an organic whole, the philosophy exists on several planes - the spiritual or religious, moral, political, economic, social, individual and collective. The spiritual or religious element, and God, is at its core. Human nature is regarded as fundamentally virtuous. All individuals are believed to be capable of high moral development, and of reform. The twin cardinal principles of Gandhi's thought are truth and nonviolence. It should be remembered that the English word "truth" is an imperfect translation of the Sanskrit, "satya", and "non-violence", an even more imperfect translation of "ahimsa". Derived from "sat" - "that which exists" - "satya" contains a dimension of meaning not usually associated by English speakers with the word "truth". There are other variations, too, which we need not go into here. For Gandhi, truth is the relative truth of truthfulness in word and deed, and the absolute truth - the Ultimate Reality. This ultimate truth is God (as God is also Truth) and morality - the moral laws and code - its basis. Ahimsa, far from meaning mere peacefulness or the absence of overt violence, is understood by Gandhi to denote active love - the pole opposite of violence, or "Himsa", in every sense. The ultimate station Gandhi assigns non violence stems from two main points. First, if according to the Divine Reality all life is one, then all violence committed towards another is violence towards oneself, towards the collective, whole self, and thus "self"-destructive and counter to the universal law of life, which is love. Second, Gandhi believed that ahimsa is the most powerful force in existence. Had himsa been superior to ahimsa, humankind would long ago have succeeded in destroying itself. The human race certainly could not have progressed as far as it has, even if universal justice remains far off the horizon. From both viewpoints, non violence or love is regarded as the highest law of humankind.
