Experimental Skills. Resistance and figure of merit of a galvanometer by half deflection method,. As you said that you have got 45 marks in jee mains and considering you have the EWS category but your percentile prediction would be difficult as these things are subject to change.
But according to my calculations your percentile would be somewhat around percentile. The first and the most important thing which every candidate and a spirit preparing for the JEE examination should keep in mind is that he needs to get his basics right in the class 11th and 12th standard. The main difference between the genius of the JEE advanced examination is the level of questions, and the number and quality of questions practiced.
There are several IIIT's whose cut offs range from lower to higher and that's why if you would tell me which IIIT are you talking about then i would be able to guide you in a more organized way.

In retrospect: The Feynman Lectures on Physics
Nuclear magnetic resonance NMR occurs when nuclei in an unmoving magnetic field is disturbed by an oscillating magnetic field; the nuclei generate an electromagnetic signal, whose frequency depends on the magnetic field applied. This happens near resonance, where the frequency of oscillation aligns with the frequency of the nuclei. The magnetic field strength, chemical environment, and isotope affect resonance. NMR spectroscopy is used to elucidate the structure of organic molecules, study crystals and non-crystals, and can be applied to medical diagnostic imaging. NMR has three basic steps: nuclear spins are aligned in a magnetic field, the nuclear spins are disturbed by a radio-frequency RF pulse, the NMR signal is detected during or after the RF pulse. Yevgeny Zavoisky observed MNR in , prior to Bloch and Purcell; however, he discarded the results as unreproducible.

5.10: Nuclear Magnetic Resonance (NMR) Theory and Solution NMR
This is the paper I always wanted to write. If you have been following my blog — and many of you have — you will want to digest this. The results are elegant and insightful. For example, the energy densities are proportional to the square of the absolute value of the wavefunction and, hence, to the probabilities, which establishes a physical normalization condition. Finally, as an added bonus, concepts such as the Compton scattering radius for a particle, spin angular momentum, and the boson-fermion dichotomy, can also be explained more intuitively.
I am posting the pdf files of my summaries of the lectures here, along with references to the corresponding sections of the textbooks, and links to any figures shown in the lectures and other relevant material. Lecture capture: For various technical reasons these lectures are not part of the University's lecture capture programme. However using the visualiser means that they are being "captured" in a more traditional medium: ink on paper. If anyone needs to see or copy something they missed, just ask me as a few of you already have.
Кармен. Ту, что работает в столовой. Бринкерхофф почувствовал, как его лицо заливается краской. Двадцатисемилетняя Кармен Хуэрта была поваром-кондитером в столовой АН Б. Бринкерхофф провел с ней наедине несколько приятных и, как ему казалось, тайных встреч в кладовке.
Треск лесного пожара, вой торнадо, шипение горячего гейзера… все они слились в гуле дрожащего корпуса машины. Это было дыхание дьявола, ищущее выхода и вырывающееся из закрытой пещеры. Стратмор так и остался стоять на коленях, парализованный ужасающим, неуклонно приближающимся звуком. Самый дорогой компьютер в мире на его глазах превращался в восьмиэтажный ад. Стратмор медленно повернулся к Сьюзан.
Не могу с ним не согласиться, - заметил Фонтейн. - Сомневаюсь, что Танкадо пошел бы на риск, дав нам возможность угадать ключ к шифру-убийце. Сьюзан рассеянно кивнула, но тут же вспомнила, как Танкадо отдал им Северную Дакоту. Она вглядывалась в группы из четырех знаков, допуская, что Танкадо играет с ними в кошки-мышки.
Она перевела взгляд на пустую шифровалку.
