Can we say that the First law of Newton defines the force whereas the Second law gives the magnitude of force?

Dear All, If two layers of thickness d1 and d2 stacked on each other and having their absolute refractive index n1 and n2 . Can we find effective refractive index of the combination with this data? Thanks in advance. Jayesh.

Hi, Thanks and sorry for late reply. But what I am asking is that in primitive stage of civilization human being are generating fire by rubbing the stones only. I am asking for this phenomenon.

Hi all, When we rub two stones and get a spark , is there any chance of static charge accumulation or it is just the mechanical energy of friction is transferred in form of heat energy. Thanks in advance. Jayesh.

Hi, I think am unable to understand the reply, could you please explain in details. Thanks. Jayesh Trivedi

Dear All, How laminated core helps in reduction of the eddy current? How reduction of area is useful in reduction of eddy current? Thanks.

Hi All, Thanks for the reply. But can I please get some more elaborate answer considering the forces. I agree that the free objects would fly into space. But I also think the effective g would be more because the pseudo centripetal would vanished. Please correct me and reply. And wishing...

Dear All, Hi I am a teacher and also new to the forum! Can someone guide me what happens if Earth stops rotating suddenly! Thanks. Jayesh.
