I guess u r ryt..Thank u all/i will try to be rich n famous ..lol

So what is the best way to determine someone's potential?I mean his /her actual intelligence ..Not how much formulas or theories he/she knows..I mean what can one do with brain ..Are u understanding..Its ineffable

Thank you all..But can we improve iq or or our intelligence by solving puzzle/playing chess or sudoku?? What does happen to brain cells when we do these mind activities! Why are we only able to use 6%of our brain?

Yea..I agree with you on that../is it true that einstein made the puzzle and only 2% can solve it?/iq results vary too much..Marilyn vos savant iq varies from 167 to 220..She is in guinness book of records for highest iq..And it is said that iq of Sir einstein was around 180! But in his...

Hola..Pardon my intrusion for this question! I m 18..I heard about einstein puzzle nd solved it correctly in like 40 -45 minutes..Then after i googled about it,i read that it is beleived that only 2%people in world can solve it..I was a little happy..lol..Anyways..I want to ask what should be my...

Its infinite..Just make sure

Hi all .. I was studying this electric field due to infinite non conducting sheet having uniformly distributed positive charge..Electric field due to it is of same direction and magnitude at any point..Which is called uniform electric field!I understood why direction of field is always...

In case of charging with induction,when a positive rod is brought near the left side of neutral sphere,electron start moving to left and right side becomes postive due to lack of electrons.Now if we ground that sphere from right side and don't move the rod?Will electrons flow from ground to the...

Oh..I understand now.. Thank u all

Yes..It is but why it neutralizes the sphere? Why its different from case when 2 identical spheres ,one negatively charged nd one neutral share charge by conduction?

Grounding is used for dircharging.. In case of charging by conduction,let a sphere having excess negative charge is brought in contact with a neutral sphere..Half of the negative charge goes into neutral sphere..But when the former sphere having excess negative charge is grounded,why it becomes...

It will make spring constant of smaller springs equal to 2k..

But how can center of mass ever be below contact point..I mean contact point is at lowest point on the surface..When does a block topple?

Please explain me the toppling giving example of a block on horizontal surface? Is friction necessary? What's its deal with center of gravity?

But what will be the angular momentum of a rotating disk/sphere about point of contact as it is rotating with¥ about centre?
