1. ## Identity Laws

Thank you for explaining it so well I must seem really stupid... Could someone also help me with what complex numbers are?
2. ## Identity Laws

I'm not sure, this is what my textbook says: Identity Laws There is a unique number 0 with the property that 0+a = a+0 = a There is a unique number 1 with the property that 1*a = a*1 =a I have no idea what that means.... By the way i'm not very good at maths so a simple explanation would be appreciated...
3. ## Identity Laws

What are these laws and how do they fit into mathematics? I am having trouble understanding them...

9. ## straight line motion and force

thanks guys for being so helpful
10. ## physics questions

why are alpha and beta particles deflected in opposite directions in a magnetic field? and also are x-rays most similar to alpha, beta or gamma rays?
11. ## alpha particle penetration

Why wolud you expect alpha particles, with their greater charge, to be less able to penetrate materials than beta particles of the same energy?
12. ## micro-organisms

hi I would like to know about these things... structure of micro-organisms culturing micro-organisms life processes of micro-organisms I am just starting a biology course so if it is possible could someone please tell me about these things? thanks
13. ## straight line motion and force

Distance, speed, constant acceleration, motion time graphs (including gradients and simple areas), mass, force (push, pull, friction, weight, reaction) i have had trouble understanding what these things are and how to calculate them so if someone could help me that would be great!
