In a major decision, the IIT Council chaired by Union Human Resource Development minister Smriti Irani has agreed to change the IIT-JEE Advanced eligibility criteria- from the existing top 20 percentile to top 20 percentile or 75 per cent marks in the Class XII board exam, whichever is lower.
Recommended by the IIT Joint Admission Board (JAB) earlier this month, the changed JEE eligibility criteria will be a major relaxation for IIT aspirants from the CBSE board system and state boards which are seen as more generous with their marking system.
The Graduate Aptitude Test in Engineering (GATE) is an entrance examination and scholarship test held by the seven Indian Institutes of Technology (IITs) and Indian Institute of Science (IISc) Bangalore. The Ministry of Human Resource Development (MHRD) creates procedures for postgraduate admissions.
The GATE 2015 examination identifies candidates for admission to postgraduate programmes in Engineering (Masters degree programme, both Master of Technology (M.Tech) and Master of Engineering (M.E.), technology, architecture, science and related disciplines at the national level.
The Indian Institutes of Technology (IITs) are considering relaxing the top 20 percentile criterion for eligibility for their engineering entrance exam, JEE Advanced.
The plan was suggested in the meeting of the Joint Admission Board (JAB) of the IITs last week.
A relation is a function if no pair of the relation has the same first elements. On the graph,two points will lie in the same vertical line if and only if the first coordinate of the two points are same. Therefore if a vertical line intesect the Relation graph at two points then it is not a function. This is called the Vertical line test. If all vertical lines intersect a curve at most once then the curve represents a function
1) First and most important things is calmness and relaxness, Be relax and reach the examination before time. Keep a positive attitude throughout the whole test and try to stay relaxed. If you start to feel nervous take a few deep breaths to relax.
2) Dont just start the paper as soon you get it. Do some planning. When you first receive your test, do a quick survey of the entire test so that you know how to efficiently budget your time.
3) Be Time Efficient. Watch the clock. Don’t spend a huge amount of time trying to get the points for one problem! If you spend too much time trying to get the points for one problem, you may not be able to finish the exam and lose more points than you gained by taking all that time for that one problem.
Show that the uncertainty relation forces us to reject the semi classical Bohr model for the hydrogen atom
In Bohr atom model we deal with the electron as a classical particle. The allowed orbits are defined by the quantization rules:
The radius r of a circular orbit and the momentum
Here our problem is to prove that the Bohr hydrogen atom approaches classical conditions when n becomes very large and small quantum jumps are involved.
To prove this let us compute the frequency of a photon that is emitted in the transition between the adjacent state
Nuclear fission is said to have occurred when nucleus of an atom splits into several small fragments. In nuclear physics nuclear fission either occurs as a nuclear reaction or as a radioactive decay process in which nucleus of an atom splits into smaller and lighter nuclei. The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a very large amount of energy even by the energetic standards of radioactive decay.
