JEE-Main, unlike JEE-Advanced, has a fixed exam structure and is not subject to change every year. Up until 2018, the JEE-Main Paper-I was three hours long and consisted of thirty questions in each of the three subjects (physics, chemistry and maths). 4 marks are awarded for correct answers and 1 mark is deducted for incorrect answers.
The AIEEE was introduced in 2002, since the newly established NITs, IIITs and GFTIs wanted an entrance examination paper of a higher standard than the Common Engineering Test (CET), which was formerly used for admission to all non-IIT engineering colleges and some state government colleges also in few states, including even RECs and IIITs, owing mostly to the rising competition and the goal of ...
JEE (Advanced) is conducted in two papers of three hours each – Paper-1 and Paper-2 (both compulsory) consist of questions from three major subjects: physics, chemistry and mathematics. Unlike most of the other exams, the type, the number of questions being asked in the paper, the total marks and the marking scheme varies from year to year ...
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
On 18 June 2012, a more specific format was proposed by a joint meeting of the councils of IITs, NITs, and IIITs. As per this proposal, the exam would be called the Joint Entrance Examination (JEE) and would be made up of two parts, JEE-Main [9] and JEE-Advanced. Two distinct "patterns of admission" would be used.
From 2012, the old pattern was Phased out and the WBJEE would consist of only MCQ questions which differs from the previous years by the fact that 2 Marks Short answers type questions are replaced by MCQ with the same weightage of marks. In 2016 there will be a different type of pattern in Biology question paper. Category-I consists of (Q.1 to ...
Work and heat are not thermodynamic properties, but rather process quantities: flows of energy across a system boundary. Systems do not contain work, but can perform work, and likewise, in formal thermodynamics, systems do not contain heat, but can transfer heat.
During this period there was little distinction between physics and mathematics; [18] as an example, Newton regarded geometry as a branch of mechanics. [19] Non-Euclidean geometry, as formulated by Carl Friedrich Gauss, János Bolyai, Nikolai Lobachevsky, and Bernhard Riemann, freed physics from the limitation of a single Euclidean geometry. [20]
