Hello everyone, I've just finished my year 12 exams and am expecting some good scores. In my earlier tests, as we do some in Jan and the rest in June in the UK, I achieved full marks in; Chemistry, Biology, Mathematics, Physics and Further Mathematics which I'm pleased about. So I'll be...

So what is smell exactly? I'm sorry if this is really basic but I'm quite confused by it. Does our brain produce the smell and it is a bi-product of chemicals? Or is it a wave like sound? Or is it something else? I'm just curious as I know what Photons and Sound is but I've never really heard...

This isn't homework, just a bit of extra study that is annoying me. Can't really seem to get my head around this bit. If you have a worked equation of Coulomb's law and all known variables; Force, Distance between two objects and the charge in Coulomb's, how do you represent this in a graph...

Thank you very much for that, helped a lot. One more thing though, how can I induce the charge into the balls (while knowing the actual charge)? The ways I have been doing it haven't been working. The equation F= k times q1q2/r2 requires me to know the charge in Coulombs (q). Those weren't my...

New to this forum as you can probably tell, if this is in the wrong place please move this. I'm doing AS Physics in a school in London and we are doing coursework for Physics. I'm trying to measure Coulomb's forces and am having a bit of trouble. The way I'm setting it up is using a torsion...
