The cylinder completely covers the marks on the metre rule. Describe, with the aid of
a diagram, how you would judge that the centre of the cylinder is directly above the
10.0 cm mark.

I saw this type of questions some other places, this was s08 in paper 6, and the MS only says: (b) clear explanation/diagram [1]

So, what would be the diagram/explanation ?
Thank you.

For Paper 6, whenever we're asked to draw the circuit diagram for a circuit, are we supposed to draw the power source in a specific way?
Like...Negative on the right and positive on the left, or the other way around

What's the symbol for the thermistor we should know?!?!
I'm always seeing different thermistors...
One time, the line going through the resistor goes from left to right, the other time, right to left

Which should I use?!?!?

How do you connect a voltmeter to measure the p.d across two lamps in PARALLEL?

i'll answer ur question but plz answer me mine ,k?

umm the voltmeter is always connected in parallel to lamps/resistors ..in this circuit , u draw another parallel line that looks the same as the ones u drew the lamps on but instead u put a voltmeter

hope i helped

Alright
So T/s starts from 1.0
Each 5 squares = .1
So it goes:
1.0    1.1.   1.2 alll the way up till 2

for l/cm
You can start from 40
each square is = to 1
thats the only way you can do it
