kr:are you telling me that R=V/I
and R=Pr/A are not related????

forget about the law of force and sh!t(sorry), i know that it was wrong.
the reason i wrote that force law is bcoz i manged to get physics books that they study in the first year in al-azhar university in gaza,and i finished it today :)
so i didn't know that much,now im better than ever ;)
im also reading this book about nuclear physics(also from gaza university).
and dont be afraid of "demotive" me,and i got that kernel :)
btw where i can buy physics books? other that jarir bookstore
