Answer»

Fundamental rights are essentially human rights but are regulated by the Constitution in Indua. These are essential for overall development of a citizen. They integrate him with the society and at the same time as they incorporate educative value also, a citizen is able to understand the importance of all the members of the society. The Constitution also provides for enforcement of these rights hence they have legal value also which empower a citizen to protect, respect and fulfill the rule of law.

1. What were the important causes of two World WaAns, The main causes of two world Wars:

Answer»

Treaty of Versailles

TheTreaty of Versaillesended World War I between Germany and the Allied Powers. Because Germany had lost the war, the treaty was very harsh against Germany.Germanywas forced to "accept the responsibility" of the war damages suffered by the Allies. The treaty required that Germany pay a huge sum of money called reparations.

The problem with the treaty is that it left the German economy in ruins. People were starving and the government was in chaos.

Japanese Expansion

In the period before World War II, Japan was growing rapidly. However, as an island nation they did not have the land or the natural resources to sustain their growth. Japan began to look to grow their empire in order to gain new resources. They invaded Manchuria in 1931 and China in 1937.

Great Depression

The period before World War II was a time of great economic suffering throughout the world called theGreat Depression. Many people were out of work and struggling to survive. This created unstable governments and worldwide turmoil that helped lead to World War II.

"Courts in India take decisions on a very large number of issues."Explain the statemen

Answer»

The Indian justice system is one of the most important pillars of the Indian democracy. But for all its power, it remains erratic, under-staffed and above all slow. The result – prominent cases such as the 1984 Sikh riots still await a final decision with many of the accused and those seeking justicehaving diedin the long 32-year wait. The direness of the situation can be gauged from that particularly embarrassing episode last year when ex-Chief Justice T.S. Thakur broke down in front of Prime Minister Narendra Modi, pleading for more resources to deal with theoverwhelming resource crunch. That old saying, justice delayed is justice denied, sadly holds true for India.

The Indian Judicial System follows a three-tier system – the lower courts, the state High Courts and the Supreme Court, India’s highest constitutional court. All three systems, currently face many challenges.

Why Do Courts Take So Long To Deliver Justice?

Securing justice is riddled with difficulties from the very start for the ordinary Indian. The procedural difficulties one faces in getting their case heard is a big contributor to the chaos in the system. From getting an FIR registeredto going to a lower court which takes its own time to decide cases and maybe even the High Court or Supreme Court in case of dissatisfaction, means a case can take years to decide. Add to this the huge number of vacancies existing in the Courts, and the situation gets truly distressing.

According to official figures, there are more than 27 millionlegal cases pendingin various courts in India, 6 million of which have been stuck in courts for 5 years or more. To manage this caseload, India has only 16,000 courtrooms and barely enough judges to preside over and carry out hearings. The Supreme Court is currently short of five judges with two due to retire in March 2017. 24 High Courts currently have 464 vacant posts for judges. In subordinate courts, this number is as high as 4,166. There is one judge for every 73,000 people in India, seven times worse than the United States.“If the nation’s judges attacked their backlog nonstop—with no breaks for eating or sleeping—and closed 100 cases every hour, it would take more than 35 years to catch up,”Bloomberg Businessweek hadcalculated.

This, even when the Law Commission of India, had recommended a fivefold increase in the number of judges in Indian courts as far back as 1987. This gaping hole in the vacancies not only creates inordinate delays in getting justicebut has brought the entire system to the brink of collapse and repeatedly contributed to what can be rightfully called ‘miscarriage of justice’.

The lack of manpower in the lower judiciary, aka the sessions court, is particularly problematicsince a major chunk of pending cases is lying in the subordinate courts. While the wheels of judicial reform through the National Judicial Appointments Commission Act did spin in terms of a new system of recruitment of judges, it got stayed through a court order that is yet to take off again.

The deeper malaise,though, lies not just in the corruption in the system or the quality of workforcebut the amount of resources the government earmarks for spending on judiciary. For the 2016 budget, only 0.2% of the budget was dedicated to the law ministry – one ofthe lowest allocationsgiven to a law ministry in the world. In comparison to India, the United Kingdom allocates up to 1.4% of its budget and USA a whopping 4.3%.

India is secular country. justify

Answer»

India is a secular state, which means that there is no official religion in India. The great Indian leaders like Gandhi and Nehru did not accept this ideology of official religion. They declared India as a secular state, which is the common Home of the Hindus, Muslims, Sikhs, Christians, Parsis and all other citizens. The result of this secularism is that in India all posts are open to members of all communities. Muslims, though a 31 percent minority, have been Presidents of Indian Republic. Dr. Zakir Hussain was one such president and Sri Fakhruddin AH Ahmad was another. In India, the Muslims, Sikhs, Christians, Parsis, Jains and members of all mino­rity communities have been ministers, governors and ambassadors without any distinction of caste and creed.

(4State the characteristics of Parliamentary Government

Answer»

The most prominent feature of a parliamentary form of government that, the Executive and the Legislature are endowed on the same authority, i. e. The Parliament.Apart from that, unlike presidential form of government, The President here acts as a nominal or ‘de jure’ executive and The Prime Minister acts as the ‘de facto’ or real executive.The party that has a Majority in the Parliament becomes the ruler party.In parliamentary system(in India) the lower house of the Parliament can be dissolved by the President.The parliamentary form of government is a system of democracy in a country. The political parties or the elected independent parliamentarians when put their head together showing allegiance to a parliamentarian , & who takes the office of the government is the basic feature of a parliamentary government. Remaining other parliamentarians become the oppositions irrespective of belonging to political parties or independents . This is in nutshell one of the basic features of a parliamentarian government.

sure and human habiswater and soil| Wanli generated theythe air. waterRadioactivemarkets.comRadioactive moteand heavy water,mines, atomie testePAGE NODATERadioactive Element

Answer»

Radioactive element. an element subject to spontaneous degeneration of its nucleus accompanied by the emission of alpha particles, beta particles, or gamma rays. All elements with atomic numbers greater than 83 are radioactive. Naturally occurring radioactive elements include radium, thorium, and uranium.

polonium is the most radioactive element

Radioactive decay(also known asnuclear decay,radioactivityornuclear radiation) is the process by which an unstableatomic nucleusloses energy (in terms of mass in itsrest frame) by emittingradiation, such as analpha particle,beta particlewithneutrinoor only a neutrino in the case ofelectron capture, or agamma rayorelectronin the case ofinternal conversion. A material containing such unstable nuclei is consideredradioactive. Certain highly excited short-lived nuclear states can decay throughneutron emission, or more rarely,proton emission.Radioactive decay is astochastic(i.e. random) process at the level of single atoms. According toquantum theory, it is impossible to predict when a particular atom will decay,[1][2][3]regardless of how long the atom has existed. However, for a collection of atoms, the collection's expected decay rate is characterized in terms of their measureddecay constantsorhalf-lives. This is the basis ofradiometric dating. The half-lives of radioactive atoms have no known upper limit, spanning a time range of over 55orders of magnitude, from nearly instantaneous to far longer than theage of the universe.A radioactive nucleus with zerospincan have no defined orientation, and hence emits the totalmomentumof its decay productsisotropically(all directions and without bias). If there are multiple particles produced during a single decay, as inbeta decay, theirrelativeangular distribution, or spin directions may not be isotropic. Decay products from a nucleus with spin may be distributed non-isotropically with respect to that spin direction, either because of an external influence such as anelectromagnetic field, or because the nucleus was produced in a dynamic process that constrained the direction of its spin. Such a parent process could be a previous decay, or anuclear reaction.[4][5][6][note 1]The decaying nucleus is called theparentradionuclide(orparent radioisotope[note 2]), and the process produces at least onedaughter nuclide. Except for gamma decay or internal conversion from a nuclearexcited state, the decay is anuclear transmutationresulting in a daughter containing a different number ofprotonsorneutrons(or both). When the number of protons changes, an atom of a differentchemical elementis created.The first decay processes to be discovered were alpha decay, beta decay, and gamma decay.Alpha decayoccurs when the nucleus ejects an alpha particle (helium nucleus). This is the most common process of emittingnucleons, but highly excited nuclei can eject single nucleons, or in the case ofcluster decay, specific light nuclei of other elements.Beta decayoccurs in two ways: (i) beta-minus decay, when the nucleus emits an electron and an antineutrino in a process that changes a neutron to a proton, or (ii) beta-plus decay, when the nucleus emits apositronand a neutrino in a process that changes a proton to a neutron. Highly excited neutron-rich nuclei, formed as the product of other types of decay, occasionally lose energy by way of neutron emission, resulting in a change from oneisotopeto another of the same element. The nucleus may capture an orbiting electron, causing a proton to convert into a neutron in a process called electron capture. All of these processes result in a well-defined nuclear transmutation.By contrast, there are radioactive decay processes that do not result in a nuclear transmutation. The energy of an excited nucleus may be emitted as a gamma ray in a process calledgamma decay, or that energy may be lost when the nucleus interacts with an orbital electron causing its ejection from the atom, in a process calledinternal conversion.Another type of radioactive decay results in products that vary, appearing as two or more "fragments" of the original nucleus with a range of possible masses. This decay, called spontaneousfission, happens when a large unstable nucleus spontaneously splits into two (or occasionally three) smaller daughter nuclei, and generally leads to the emission of gamma rays, neutrons, or other particles from those products.For a summary table showing the number of stable and radioactive nuclides in each category, seeradionuclide. There are 28 naturally occurring chemical elements on Earth that are radioactive, consisting of 33 radionuclides (5 elements have 2 different radionuclides) that date before the time of formation of the solar system. These 33 are known asprimordial nuclides. Well-known examples areuraniumandthorium, but also included are naturally occurring long-lived radioisotopes, such aspotassium-40. Another 50 or so shorter-lived radionuclides, such asradiumandradon, found on Earth, are the products ofdecay chainsthat began with the primordial nuclides, or are the product of ongoingcosmogenicprocesses, such as the production ofcarbon-14fromnitrogen-14in the atmosphere bycosmic rays. Radionuclides may also beproduced artificiallyinparticle acceleratorsornuclear reactors, resulting in 650 of these with half-lives of over an hour, and several thousand more with even shorter half-lives. (SeeList of nuclidesfor a list of these sorted by half-life.)

Describe in brief the language policy ofIndia(CBSE 2008)

Answer»

(𝒊) 𝑵𝒐 𝑵𝒂𝒕𝒊𝒐𝒏𝒂𝒍 𝑳𝒂𝒏𝒈𝒖𝒂𝒈𝒆: Our Constitution did not give the status of national language to any one language. Hindi was identified as the official language. But Hindi is the mother tongue of only about 40 per cent of Indians. Therefore, there were many safeguards to protect other languages.

(𝒊𝒊) 𝑺𝒄𝒉𝒆𝒅𝒖𝒍𝒆𝒅 𝑳𝒂𝒏𝒈𝒖𝒂𝒈𝒆𝒔: Besides Hindi, there are 22 other languages recognised as Scheduled Languages by the Constitution. A candidate in an examination conducted for the Central Government positions may opt to take the examination in any of these languages. States to have their own official languages. Much of the government work takes place in the official language of the concerned State.

(𝒊𝒊𝒊) 𝑺𝒑𝒓𝒆𝒂𝒅 𝒐𝒇 𝑯𝒊𝒏𝒅𝒊 𝒘𝒊𝒕𝒉 𝒕𝒉𝒆 𝒄𝒂𝒖𝒕𝒊𝒐𝒖𝒔 𝒂𝒑𝒑𝒓𝒐𝒂𝒄𝒉: Unlike Sri Lanka, the leaders of our country adopted a very cautious attitude in spreading the use of Hindi. According to the Constitution, the use of English for official purposes was to stop in 1965. However, many non-Hindi-speaking States demanded that the use of English continue. In Tamil Nadu, this movement took a violent form. The Central Government responded by agreeing to continue the use of English along with Hindi for official purposes. Promotion of Hindi continues to be the official policy of the Government of India. Promotion does not mean that the Central Government can impose Hindi on States where people speak a different language.

what was the simon commission? why did the indian national congress opposed it.

Answer»

The Indian Statutory Commission was formed in 1927 to gauge the progress of constitutional reform in India. It consisted of seven members and was usually referred to as the Simon Seven or the Simon Commission. All seven members of the commission were also members of the British Parliament

It was opposed by national Congress because:1)It was an ‘all-white’ commission,that is to say,no representation of any Indian in the ‘Simon Seven’.Reasons being to avoid any ‘bias’ and ‘incompetency’.Naturally,protests started.

2)Secondly,at that time,Indians were all ‘charged-up’ and they wanted nothing less than complete freedom from the British yoke but Simon Comission again talked about ‘dominion-status’.So,ultimately,it was boycotted.
