Because my Physics teacher is incapable of explaining things like this, or fobs me off saying that "you study this at A-Level", I was wondering whether you guys could help me with some Physics stuff.
Firstly, what actually is a volt? I hear the term "potential difference" which makes me think it's a difference between two things, but I have no idea how one would then "change" a voltage, and generally what it is.
Secondly, apparently putting a coil of wire perpendicular to a magnetic field induces a flow of charge in that coil (from what I can remember). Why does it do this?
And finally, why does strontium emit beta radiation as opposed to alpha and gamma? What makes an element give out a particular type of radiation in decay?
Thanks for any responses!
