    B Explanation of what a parameter is

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

    B Explanation of what a parameter is

    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.

    B Deriving pV=NkT from N=Na*n and k=R/Na

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

    B Deriving pV=NkT from N=Na*n and k=R/Na

    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

    B Deriving pV=NkT from N=Na*n and k=R/Na

    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...

    B What is Flemming's Left Hand Rule and How Does it Relate to Current Flow?

    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...

    B What is Flemming's Left Hand Rule and How Does it Relate to Current Flow?

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

    B What is Flemming's Left Hand Rule and How Does it Relate to Current Flow?

    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...

    Magnetic field/circular motion equation derivation

    How would you derive f=BQ/2pim ? I've got as far as F=BQv, but now I don't know which centripetal force equation to use; either F=mv2/r or F=mw2r Update: no worries I've done it

    B Gravitational field strength calculation

    Ahh I see that makes sense, thank you

    B Gravitational field strength calculation

    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...
