The normalisation procedure for normalisation of 12th marks in JEE MAINS is totally stupid and annoying to students . It seems that the procedure was developed by some mantles without even thinking of droppers .Let's consider two students ;Student A : Let A passed the qualifying exam in year 2013. A is a product of exam oriented RATTAFICATION SYSTEM OF CBSE . A doesn't have any scientific or engineering brain but has a good command over English . A has very good relation with his teachers , so he gets full marks in practicals (30/30 in physics and chemistry and 70/70 in music ) . So A has already got 130 marks without studying anything . Due to the good hand   ...

"Take care of the minutes and the hours will take care of themselves."~Lord Chesterfield~Time seems to be at a premium in today's fast paced life. To be successful in every aspect of life, it is essential to set your priorities and meet the deadlines. As a student, an individual should manage his time throughout the year. A lack of effective time management skills may increase your stress level. There are some effective time management strategies that you must follow:Make a To Do ListFirst of all, prepare a to-do list from mundane to the critical work. By doing so, you can focus on the important objectives. Work on the tasks which you want to   ...

The detailed example now has been posted on official JEE Mains website and that confirms the worst fears.A difference of only 25 numbers in Board Marks (out of 500) between two students scoring 96% and 91% would be transplanted as a difference of 263 marks (343-80 for same percentile diff). That is inflating diff by 1000%. Almost all JEE Mains top scorers are likely to be blown away.Below is the table showing relative steep difference at top percentile (which matters for admission in NITs.)%ile    JMains     Board        BoardNumbers Numbers Percent2.31    10        ...

 Author: nitin.p070Newton's law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. (Separately it was shown that large spherically symmetrical masses attract and are attracted as if all their mass were concentrated at their centers.) This is a general physical law derived from empirical observations by what Newton called inductionEvery body attracts every other body in this universe with a force which is proportional directly to the product of the masses of the bod   ...

 Author: Smruti Ranjan SarangiOscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs. Learn more about OscillatorsOscillation is the periodic variation, typically in time, of some measure as seen, for example, in a swinging pendulum. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is use   ...

 Author: P. Surya PrakashThe water stored in a dam possesses potential energy by virtue of its height. When this water is allowed to fall, its potential energy change into kinetic energy. Due to its kinetic energy, the falling water can rotate the turbines and produces electricity. Thus PE is converted into KE. In other words, the total energy remains constant when a body changes its position, though one form of energy may be converted into another. This leads to law of conservation of energy.Chemical thermodynamics is the branch of thermodynamics which deals with study of processes in which chemical energy is involved. The study of thermodynamics is based on t   ...

 Author: BennyEngineers specify physical quantities in two different—but conventional— systems of units: the United States Customary System (USCS) and the International System of Units (Systeme International d'Unites or SI). Practicing mechanical engineers must be conversant with both systems. They need to convert quantities from one system to the other, and they must be able to perform calculations equally well in either system. In this textbook, examples and problems are formulated in both systems so that you can learn to work effectively with the USCS and the SI. As we introduce new physical quantities in the following chapters, the correspon   ...

 Author: Rahul JaswalYou may have heard about the three laws of motion at some point of time in your life, or maybe not. If you're a science freak, you'd definitely know what the three laws are, but if you're still reading this, then you sure do want to know about three of the most important laws in the history of time, Newton's Laws of Motion.These laws, as the name suggests describe the relationship between forces acting on a body and its motion due to these forces. These were formed by Sir Isaac Newton and published on July 5, 1687. He would use these laws to explain more about the motion of many physical objects and systems. The Laws of moti   ...

By Leah FischCatalytic alkene reduction is a common mechanism that you will come across when reviewing alkene reactions. Reduction is the reaction in which you reduce the oxidation number of an atom, by either adding electrons or hydrogens to the atom in questionsIn an alkene reduction, what starts out as a carbon to carbon double bond where the pi bond is just two electrons, you wind up with a hydrogen atom attached to each of the sp2 (double bond) carbon atoms. The initial pi bond had just 2 electrons, but the hydrogen atoms each come along with another electron for a total of 4. This addition of 2 electrons, 1 for each hydrogen, is by definition, the reduction pr   ...

By Garik TateFirst before we discuss the individual blocks and groups the compose the periodic table of elements lets talk about the system its organized in. For the purpose of this I am going to assume you are looking at a periodic table while you are reading this.First there are the blocks. There are 3 blocks S D and P. The first block (the S block) is on the left of the table and is composed of the first two vertical lines (also called groups). it should be noted that hydrogen does not belong in any of the 3 blocks. The two groups that compose them are the alkali metals and alkaline earth metals.Then there is the D block. The D group is like a mixture between fir   ...

By Charles DementorA chemical reaction is a process that always results in the conversion of reactants into product or products. The substance or substances initially involved in a chemical reaction are called reactants. A type of a chemical reaction is usually characterized by the type of chemical change, and it yields one or more products which are, in general, different from the reactants.Generally speaking, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds. Chemical equations are often used to describe the chemical transformations of elementary particles that occur during the reaction   ...
