Thank you very much, I understand it better now

I see now, thank you very much for your help.

Thank you for replying, so are m and b parameters here because they have a fixed value (are constants) for this particular line equation?

Please could someone explain, pretty simply, what a parameter and also its relation to graphs? And if possible give a couple of examples. I have trawled through the internet and can't find anything which I understand. Thank you very much.

Ohhh ok, I see how its done now, thank you

Ah yeah sorry, it wasn't clear, basically I wanted to know what you would derive pV=nRT from and then how you would derive it from those equations, but also it would be good if you could tell me how to get from pV=nRT to pV=NkT

I've attempted to use N=Na*n -where N is that total number of particles of a gas, Na is the Avogadro constant and n is moles. And then attempted to use k=R/Na -where k is the Boltzmann constant and R is the molar gas constant. I got as far as N/n=R/k but then not sure how to get from this to...

ahh ok I see thanks!

Ok so in a question about electromagnetic induction, say it says 'state the direction of the flow of current in a conducting rod' you would use Flemming's right hand rule to determine that But then say it said 'state the direction of movement of an electron in a conducting rod'- it would be in...

Ok, so for Flemming's right hand rule does it also represent conventional current?

For Flemming's left hand rule, your second finger represents the direction of flow of current (in the current carrying wire perpendicular to a magnetic field), so does the direction of the current show the direction of flow of electrons or does it show the direction of the conventional current...

Ahh I see that makes sense, thank you

In what scenarios would you use the equation g= F/m instead of g=GM/r2 (or vice versa), for calculating gravitational field strength? Update: is g=F/m used to find the force acting on a mass in a gravitational field (of strength g), whereas g=GM/r2 used to calculate the gravitational field...

Thank you!

What is the momentum of a ball at the exact point where it comes into contact with a wall?
