AIEEE (Now JEE-Mains) Question paper to download from 2002 to 2012 with solutions.

JEE-Mains (earlier AIEEE) is now difficult to judge that what will be the level of the question. Will it be AIEEE level or a level between AIEEE and IIT or NCERT level. Many of the students have this doubt but experts have suggested that students preparing for JEE-Mains exam must concentrate on AIEEE question paper. Well you must have to study your NCERT book to clear the concept but AIEEE questions are similar to that of Miscellaneous exercise questions. Such questions are application based also. So, for solving such questions you must clear your concept on the same.

Now if students have to solve AIEEE level questions then they must attempt the AIEEE questions which you can download from below. Question Papers which is present in pdf format are set according to the year and you can download it year wise. Downloading link is an external link and when you will click on it you will be redirected to another website. Solutions are also provided with question paper.

Register your board roll no. to JEE-MAINS application.

Recently a portal has been activated for the students who have applied for JEE-MAINS this year. As both Board marks and Jee-mains marks will decide your rank and also the engineering collage so it has become important to score good marks in both exams.

Admit Card Jee Mains

Now Jee-mains website has opened a portal which allows students to register your board roll no which will  aks you for your application number, candidate's name, mother's name, date of birth and a security pin . Candidates must  fill up the same information which they have mentioned earlier while registering for JEE-Mains. As both board and jee mains marks are going to be calculated together that's why they are asking for your board roll number. Last date to register the roll number is 25th April 2013

After submitting the information a new window will appear which will consist a brief detail about the candidate and there you have to register your board roll number at the main website of Jee Main.
Feel free to ask any doubt and query through comment or e-mail.

Exact meaning of infinity both as theoretical and mathematical concept.

Infinity means:-
1.Unlimited    OR   when we use this term in Mathematics as infinity-1 (to subtract 1 from infinity)
  then you can imagine it as to subtract an ANT from EARTH.

infinity means no limit. so we can't find the end point of infinity.

 Why infinity(*,/,+,-) with/by 10000000000000000
remains as it is.

Infinity is an hypothetical concept to which we consider to be, but actually can't find it.Because in actual it is not a place to which we can reach or area to which we can find.

In class 9th,10th,11th and 12th we encounter with the problems in Mathematics or Physics or even Chemistry which contains the concept of infinity or we need to find the answer at infinity or for infinite time,etc.Here we take infinity as a point(in physics as to find electric field at infinity or to bring a charge from infinity at electric field.) to which we imagine as a small point which is very far away but where it is or exactly what is the distance we don't know.

But when we *(multiply) infinity with some no. then also it results to infinity because after infinity we dont't know that what will be there or we haven't find a point greater than infinity.


Why 1/0 is equal to infinity.

1/0 = infinity.

as- consider an area or forest with 1Lakh trees and 5 men are there to cut 1 lakh trees.
here if we divide the work equally among them  then each of them will get 20,000 trees to cut as

1 lakh/5 = 20,000.

but when we want to cut 1lakh trees and we have no men to cut those trees then it means that

1lakh/0 = INFINITY.

because there is no man available to do work which means the work will not going to be finish or the time to finish this work will be infinity.

Here we know that work is not going to be completed but then also we can consider that this work will be finished till Infinity.

How global warming is biggest threat for humans and how can we protect our environment?

At present our biggest enemy at world level is Global Warming because we humans have approximately controlled every thing but still we are failed to rule over this problem. Humans are the only reason for global warming and only we can recover it but still its very much difficult task for us.

What is Global Warming and reason behind it?

Global warming is basically increased temperature on earth due to green house effect and the reason behind this is excess of Carbon dioxide gas in our environment. Co2 gas is not a harmful gas ,even though we humans inhale O2 gas and exhale Co2 gas but the thing is that its presence in excess amount is the reason. In our day to day life we use moter vehicle to travel a distance and that vehicle also release Co2 gas. Just think about it that there are Billions of people living in this planet and every one release Co2 gas in fact we all use different kinda moter vehicle which also produces Carbon dioxide gas and similarly there are lots of industries who are manufacturing goods and releasing carbon dioxide gas as a waste so basically i want to say that there are lots of ways through which carbon dioxide gas is releasing every day. Many things cause global warming. 
One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses. 

Global warming-As our enemy

At present our biggest enemy at world level is Global Warming because we humans have approximately controlled every thing but still we are failed to rule over this problem. Humans are the only reason for global warming and only we can recover it but still its very much difficult task for us.
Basically Global Warming is our biggest enemy because of human nature also as we all think about present and never plan for future in such cases because we don't have seen the outcome of this problem.If we are not going to take some steps against global warming or not going to recover from this problem then we all have few years to live on this planet. We should find some another planet to live if we can't take care of our home planet earth.

How can we protect our environment?

If we really want to solve the problem of global warming then we must measure some steps so that we can save our life and our planet earth too. We should plant more and more trees and also take care of it if we want to live our life further on this planet. As plants and trees are the biggest source which provide us Oxygen to live and food to eat. In fact trees and plants take carbon dioxide and for this they provide us oxygen gas. Which means that trees actually using this co2 gas and decreasing the concentration of co2 in our environment. People are doing many things to try to stop global warming.
One thing people are doing is carpooling. Carpooling is driving with someone to a place that you are both going to. This minimizes the amount of greenhouse gases put into the air by a car. Greenhouse gases absorb infrared radiation and prevent it from escaping to space. Carbon dioxide, methane, and nitrous oxide are very good at capturing energy at wavelengths.
Another thing that people are doing is being more careful about leaving things turned on like the television, computer, and the lights. A lot of people are taking time away from the television, and instead, they are spending more time outdoors. This helps our planet out a lot. Now, more people are even riding busses, walking to school, and riding their bikes to lower the amount of greenhouse gases in the air. Planting trees and recycling also helps. If you recycle, less trash goes to the dump, and less trash gets burned. As a result, there are fewer greenhouse gasses in our atmosphere. Watch what you buy. Many things, such as hairspray and deodorant, now are made to have less of an impact on the atmosphere. Less greenhouse gasses will rise into the air, and global warming will slow down.

Results of Global Warming

As global warming is increasing day by day so we can even notice this phenomenon by listening news regarding temperature report. Every year temperature is increasing and it is always found that the this temperature is higher than that of previous year's temperature. We can see flood in different areas which is due to the melting up of glaciers and thus results in the increase of water level in river, seas and oceans. 

Reformation of Ozone Layer(2013 news)

Recent study have found that there is a fine decrease on the graph of Depletion of Ozone layer. Previously it was decreasing with full acceleration but now the graph not only slows down but it has shown a good increment on the reformation of ozone layer.

What is Ozone Layer ?

Ozone layer is basically a gas [O3] in which 3 elements of oxygen are bounded with each other together to form a compound of Ozone. Ozone layer is a blanket which protect our earth from the harmful U.V rays. ozone layer gets its name from ozone gas, an allotrope, of the element oxygen. Ozone gas has become so synonymous with the ozone layer that people now refer to the layer as 'the ozone.' 

If we are going to encounter with these rays directly from the sun then we are going to face many disease and skin problems:-ultraviolet radiation causes erythema, sunburn, photo damage, photocarcinogenesis, damage to the eyes, alteration of the immune system of the skin, and chemical hypersensitivity. Skin cancers most commonly produced by ultraviolet radiation/rays.

                                                    -->

Ozone Layer depletion.

Many people among us are aware that our ozone layer was depleting in the near by areas of Antarctica which was increasing again and again. The ozone layer can be depleted by free radical catalysts, including nitric oxide , nitrous oxide, hydroxyl, chlorine , and bromine.Especially chlorofluorocarbons (CFCs) and bromofluorocarbons(BrFCs).

These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 100,000 ozone molecules. The breakdown of ozone in the stratosphere results in the ozone molecules being unable to absorb ultraviolet radiation. Consequently, unabsorbed and dangerous ultraviolet-B radiation is able to reach the Earth's surface. 

Ozone levels over the northern hemisphere have been dropping by 4.77% per decade. Over approximately 5.39% of the Earth's surface, around the north and south poles, much larger seasonal declines have been seen, and are described as ozone holes.

No Need to worry as Ozone layer is reforming again.

Recent study have found that there is a fine decrease on the graph of Depletion of Ozone layer. Previously it was decreasing with full acceleration but now the graph not only slows down but it has shown a good increment on the reformation of ozone layer.

From the last decade researchers have found that Ozone layer is recovering itself again which is a good news and the reason behind this is just humans intelligence only. After knowing that Ozone layer is being depleted and we are now in a big danger,we humans have reduced the use of chlorofluorocarbons (CFCs) which helped environment a lot and it is now recovering on its own.

What would have happened if we have increased the use of (CFCs) and other harmful gases?

If we will increase the use of those gases then it would be again found to be a big reason of worry about the future of the earth. If we would have not stopped all this then it might be possible that we have to leave the whole southern part of the earth and humans might be living on northern part of the earth only.

If we will not going to think about global warming also, then we might going to loose the whole earth and it will be impossible to recover from those hazardous injury which our earth is going to face in future. 

What is better to choose online or offline mode for Jee-mains 2014

After knowing about all aspects of JEE-Mains a big question arises that which mode/form should we opt. for-online or offline.?
The best advantage which i came to know about this mode is that if you will mark any answer/select any answer then you can re-correct it by going back to that question where as in offline mode we have to use black/blue ball pen to mark the question and once if its is marked then it can't be corrected again as no cutting is allowed.
Well both of them have their own benefits and demerits also and here i will explain you how:-

ON-LINE MODE:- 

Advantage:-

The best advantage which i came to know about this mode is that if you will mark any answer/select any answer then you can re-correct it by going back to that question where as in offline mode we have to use black/blue ball pen to mark the question and once if its is marked then it can't be corrected again as no cutting is allowed.

Disadvantage:-

As we are going to give the paper with the help of machine(computer) and with the  internet connectivity
then there is no guarantee that when they are going to be damage.Damage in the sense that -when we are giving the exam then computer might going to be hang or server can be down at that time.Moreover like other exams questions will appear one by one and if you are not able to solve those questions then you might got tensed.(::::-it is not confirm that questions are going to appear one by one.)

OFF-LINE MODE:- 

Advantage:-

In this mode the main advantage is that you can go through any of the section quickly(manually) and hence you can go through any of the question at any time.If you are preparing for IIT/AIEEE from any of the institute/coaching then you have practiced with this offline mode(pen and paper mode) only which provides an edge to your way of giving/attempting the exam.

Disadvantage:- 

As mentioned above that if you have selected(bubbled/marked) any of the answer in answer sheet then you are not allowed to re-correct it.

What will you do now..?

Now after knowing about advantages and disadvantages in both the section you can your self decide that which of the above mentioned is more convenient to you.So you have to choose that which will be better for you.
