Physics Anyone? ~ PLEASE HELP

Can anyone please help me? I don't understand anything of this ... I'm in year nine and a total catastrophy in physics... T.T

I need to know about the magnetic field of a current-carrying conductor, the Lorentz-power, What Isotopes are, characteristics of radiation.. the alpha/beta/gamma radiation...

ALL THIS! FOR TOMORROW! T.T

If anyone iswilling to spare someknowledge for my stupid brain please do it! PLEASE!

That's a lot of content you have to cover by tomorrow...
I'm in year 10, I live in england but it should be similar to what you're learning. I use this site: http://www.bbc.co.uk/education/subjects/zpm6fg8
Not sure if it has anything about lorentz power, but it has some of the other stuff you mentioned so... I hope it still helps somewhat? :o
