Apologies for late posts

Dear Friends, I am really sorry for the late posting of the posts and I feel that it might have somehow been a problem to all of you. Hence I promise you that I will be posting at least three topics revision notes on my blog every week. I wanted to do more but due to my own schedule I am unable to push it further. I have got high hopes from this blog and now being in college I can devote myself to this blog even more.

Just to let you know, from now onwards this blog will mostly be a go to place for those students who are looking for some reliable resource from where they can get enough revision for there weekly tests or phase tests or any related tests of JEE/NEET. I was also a JEE aspirant but due to my lack of note making, I could not get into the IIT's. But nevertheless, I am now a student of DTU civil branch and I strongly recommend you all to make proper notes and go through them as this creates the difference between an IITian and the rest. But still, if due to some reason you end up with not so good notes, then these revision notes will be really handy ONLY WHEN YOU HAVE PAID SOME ATTENTION IN YOUR CLASSES AND AT LEAST SOLVED CLASS EXAMPLES.

Therefore I wish you all the best for your future endeavours and stay tuned for the notes.

Simple Harmonic Motion

SHM is a kind of periodic motion. We can say that all SHM's are periodic but all periodic motion are not SHM.  Conditions for SHM: The acceleration of the body or the particle should be proportional to the negative of displacement. The total Mechanical Energy of the system remains conserved. There must be a state of stable equilibrium. Equation of SHM Consider a particle revolving around a circular path of radius ''a''. with a constant angular velocity  ω. Let at time t=0, the particle is at the position A then the projection of the particle will be at the point B on the y-axis. So when the particle comes at the top the projection also comes at the top. Hence we can see that the particle is doing periodic motion but the projection is doing SHM. Hence the time period of the SHM is same as the time period of the circular particle. The derivation of the actual equation of the SHM is a bit complex and it is difficult for me to show it here so...

Limitations of Mendeleev's Periodic Table

Mendeleev arranged 63 elements known at that time in the periodic table. According to Mendeleev “the properties of the elements are a periodic function of their atomic masses.” The table consists of eight vertical column called ‘groups’ and horizontal rows called ‘periods’ Limitations of mendeleev’s classification : (i) He could not assign a correct position of hydrogen in his periodic table, as the properties of hydrogen resembles both with alkali metals as well as with halogens. (ii) The isotopes of the same element will be given different position if atomic number is taken as basis, which will disturb the symmetry of the periodic table. (iii) The atomic masses do not increases in a regular manner in going from one elements to the next. So it was not possible to predict how many elements could be discovered between two elements.
