yeah i just hope that 13/14 mark experiment is one i know properly.. do u have a list of experiments we are supposed to know?
i know that the main ones are
1) finding emf and internal resistance
2) finding spring constant
3) young's modulus

any others..

Also learn the experiment where you have to find the resistivity of a wire.
Once they asked the students to determine the power of a person...

oh yeah sorry i forgot to mention those two as well .. you seem really prepared..

 

[Nafis Daiyan]

I am pretty well prepared
You said that you have a problem with straight line equations...give an example of a question and I'll try my best to explain

yeah may 13 question 8 unit 3

First of all, c=fw [w=wavelength...i can't write lamda here ]
therefore, f=c/w
eV=hc/w
Make V the subject, as they want V on the y-axis:
V=hc/ew
V=hc/e * 1/w

Compare it with the equation of a straight line, y=mx +c.
Here, y=V, m=hc/e, x=1/w and c=0
m is the gradient of the line, so the gradient of this line should be hc/e...

okay but i just cant wait to discuss answers lol
