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.
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...
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...
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...
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
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...
