for the melting curve, marks allocated is [2]
i drew a line from -2(dc) to 1(dc), straight line for a few grid
then a curve to 4(dc)
The electricity part:
I wrote, it will require more energy to heat up all the water,
causing wastage of electricity than compared fig12.1.
For the focal length, my teacher said that you have to label
that part and write the distance there and they will mark
according.
for this paper is quite easy, they might not accept candidate
who just referred to the graph to get the distance of focal, you
may need to draw dotted line to show that, that is the focal with
your distance. If you do, even ur dis is 1.6, will they accept it,
according to Fig 6.1 labelled in qn.
For the negative plate, i state that gain neg char up the wire,
attracted by positive, then when attracted. aft tt its all crap.
hope i get at least 1 mark. cos i mixed up by writing when the
particles reaches pos plate, it GAINS electron, then charges
changed positive towards the negative plate.
