Sir I am a 9th class student and I've a doubt that a simple pendulum has a time period of 2 sec at the earth's surface. if it is taken to a height equal Re, above the earth's surface, where Re is the radius of the earth, find the time period.
I have a doubt... Work done is force × displacement So how electric work is done?? Because in case of electricity there is no displacement.. So how the electric work is done??
@@jayantideshpande8459in a closed circuit workdone is of two types one is due to chemical mechanism of battery and other is movement of electrons due to electric potential In physics we consider due to electric potential in wire W= F.d, F = qe so e× d is dv W=q dv here d is net distance or displacement between two electrodes Here we just pass electrons from negative terminal to +ve terminal not within the battery If we add both work done( p and c) then net is 0
🙏☺️ sir, we are blessed with teachers like you to clear our doubts and I have started to think that Google is not the place where physics is learnt or understood properly. Teachers and reference books are the place where we can get our doubts cleared. Google can give us the principles and phenomena behind numerous natural or artificial events instantly but GOOGLE IS NOT ENOUGH TO DEVELOP A SYSTEMATIC THOUGHT PROCESS NEEDED TO UNDERSTAND PHYSICS. Thanks again to enlighten us 🙏☺️.
Johannes Kepler was a mathematician, astronomer, astrologer, and natural philosopher . In short , he was a true allrounder and knowledge seeker . A simple example of how a good student can also achieve great things . A complete contrast of how Einstein was with his teachers and school . Both are great and it simply proves a point , one needs to invest time in seeking knowledge in a proper manner , it will never go waste 🙂
Dr H C Verma Sir, Your knowledge is amazing .... well-known fact! But what's even more amazing and rare is the humility that goes with it. Thank you sir, for being the exemplary human you are :)
Thank you for writing & publishing concepts of physics, a book loved by millions. Thank u for making physics my fav subject, back in 2012. A warm gratitude for you sir. God bless u.
Sir I am from Patna,My name is Swastik Jha I have watched one of your lecture on why does yellow light doesn't split while passed through prism from that particular instant my curiousty for getting answers of interesting question went up so for that I started watching answers of all question you have answered on this channel and they are extreme fabulously explained by you .There is a humble request from me plss try to make one shot lecture of of any extra interesting chapter like Walter lewin does atleast in a year.

Two blocks of same mass are hanging from pully one is hanging vertically another is kept on a plane and makes angle theta at the pully. If the 2nd one is moving with a1 acceleration the first one will move with a1cos theta or a1cos theta - v1 sin theta dteta/dt
Sir i think temperature and time are proportional to each other as motion of molecules stops when we freeze something and motion of molecules accelerate when we increase temp . So do all the molecules freeze when we set temp to -273kelvin? i know this temp is imaginary.
Consider a mass-pulley system. There is a wedge of mass M and equal wedge angles θ lying on a rigid horizontal table. The coefficient of friction between the wedge and the table is µ. There are two blocks of mass m1 and m2 lying on the incline of the wedge. The coefficients of friction between the blocks and wedge are µ1 and µ2 as shown in the figure. Consider m1 > m2 and the coefficients of friction (µ, µ1 and µ2) to be less than tan θ. Gravity is acting mi downwards with acceleration due to gravity g. What should be the value of so that the system m1/m2 is in equilibrium?
Requesting for your reply since 2 years, though in class 9th, I have completed theory, all numericals from the books written by prof.

Hello Sir, i was solving gravitation and the last question of the exercise that is q. 39, it made me curious... Can you throw some light on it about why you chose the escape velocity to be speed of light...
Sir, पृथ्वी सतह पर औसत गुरुत्वीय त्वरण 9.8m/s^2 जो ध्रुव पर सबसे अधिक एवं भूमध्य रेखा पर न्यूनतम होता है। गहराई पर जाने पर और ऊंचाई पर जाने घटता है। पृथ्वी के केंद्र पर 0 होता है। मेरा प्रश्न यह है कि पृथ्वी सतह से कितनी ऊंचाई पर गुरुत्वीय त्वरण शून्य होगा?
