i was just thinking over line that my teacher told - "Newton's second law is ultimate truth" i feel why one can say 'F=ma' is more prestigious th 'work energy method' Though i know they are one and same thing, i was planning to derive (using principle of reverse engineering) second law of...

ok i provide you a large charge carrier carrying charge of 1010101010 :-p electrons now define current vs one 'charge carrier' like single electron Your 'amounts are same' but current...

well yeah like you cannot explain current in amounts and time only for eg. 1-CURRENT = θ/T θ IS YOUR SPOKEN AMOUNT T IS YOUR TIME 2-BUT QUESTION WILL COME WHAT AMOUNT AND NOW IF YOU USE SOME THING LIKE 10 COULOMB CHARGE 3-MY NEXT INTERROGATION IS WHAT IS COULOMB THEN PROBABLY (by definition)...

Well thank your for your respective posts but I'm just in high school and concepts like divergence and curls have not been given to me it was just a question in my paper for school exams preparation that came and i went thinking till this point So just small question Is there any blunder...

Well many complex questions may be placed over this the question becomes very diverse AND DIVERSE firstly you must refer to vsepr theory then facts like "lone pair lone pair" repulsion are more etc adding to it someone mAY put forward the favorite exceptions like "drago's rule" etc...

i had a question in my paper why electrostatic field lines cannot be discontinuous in charge free region i guessed a weird (but an innovative proof) Tell me is it correct So here it goes "Let's assume that ELOF can be discontinuous Then i draw a diagram of broken electric field Now...

Hey guys i had a question in my paper why electrostatic field lines cannot be discontinuous in charge free region i guessed a weird (but an innovative proof) Tell me is it correct So here it goes "Let's assume that ELOF can be discontinuous Then i draw a diagram of broken electric...

F(external)=ma mg-N=ma direction of a downward or if a is upwards N-mg=ma N=mg+ma

the a i made is acceleration of lift. so it's pseudo force acts downwards and equation comes out same. also 'a' is negative ,and the positive direction of 'a' is upwards so 'a' overall in example one NET ACTS DOWNWARDS. don't match it with sign convention because my explanation itself has an...

AS FAR AS I KNOW IT DEPENDS ON CONVENTION THE VALUE OF g if you take upward direction as positive it'll be positive but maybe i am wrong, i ve a link that supports me (maybe) https://www.physicsforums.com/showthread.php?t=260060

actually it all depends on sign convention

actually the formula seems a bit of no use to me.I always sketch the free body diagram of lift in my brain and then doing some pseudo force work the question is solved ALWAYS! in the first part for sure lift accelerate downwards. the guys who done with the formula considered "a" (the base of...

centripetal acceleration is caused to continue circular motion so at every point. so at that point it has to accelerate the mass toward center so as to change it direction. now for at the point it has angular velocity omega then centripetal acceleration will vary with that only

i may be wrong but free expansion may be a way out i.e. expansion in insulated evacuated chamber http://en.wikipedia.org/wiki/Free_expansion

thanks abitslow, you really worked hard over the text but your work was tooo.. scientific and high fi, i mean that I AM JUST in 11th AND FOR SURE THE INITIAL LINES WERE GONE OVER MY BRAIN (over that quantum part and mot..) also my question was that what was the difference between the two...
