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 Joint Entrance Examination – Main (JEE-Main), formerly All India Engineering Entrance Examination (AIEEE), is an Indian standardized computer-based test for admission to various technical undergraduate programs in engineering, architecture, and planning across colleges in India.
However, with the two stage JEE-Main + JEE-Advanced structure from 2013, [48] the number of candidates in JEE-Advanced is fixed at 150 thousand students in 2013 and it is increased in subsequent years to 250 thousand as of 2022. [49] The total seats available in each institute (Seat Matrix) is summarized in table below. [50]
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.
The resonance effect of the LC circuit has many important applications in signal processing and communications systems. The most common application of tank circuits is tuning radio transmitters and receivers. For example, when tuning a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.
The sound generator is turned on and the piston is adjusted until the sound from the tube suddenly gets much louder. This indicates that the tube is at resonance. This means the length of the round-trip path of the sound waves, from one end of the tube to the other and back again, is a multiple of the wavelength λ of the sound waves. Therefore ...
Increase of amplitude as damping decreases and frequency approaches resonant frequency of a driven damped simple harmonic oscillator. [1] [2]Resonance is a phenomenon that occurs when an object or system is subjected to an external force or vibration that matches its resonant frequency, defined as the frequency that generates the maximum amplitude response in the system.
In chemistry, the mesomeric effect (or resonance effect) is a property of substituents or functional groups in a chemical compound. It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom. [ 1 ]
