light question plz

http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Physics (0625)/0625_w10_qp_61.pdf
question 1 can u xplain wat exactly si triangle method??for gradient
question 3 c
question 4 light question paert a i
I HATE LIGHT QUESTIONS

I hope you can understand this :/
you just substitute and write your derivation in part (iv) and (v).

In the next paper, you don't have to use the gradient method
but the gradient method anyway is like:

• The vertical distance between (0, 0) and (70, 98) is 98.
  
  
• The horizontal distance between (0, 0) and (70, 98) is 70.
  
  
• 98 ÷ 70 = 1.4

So the gradient here will be 1.4, i.e, vertical distance/ horizontal distance.

3)c) statement: no
justification: within limits of experimental accuracy (always use this statement ), l increases V decreases, say this by by reference to results.

4)a)i) just like i marked the pins on the previous diagram.

My Name, i doubt you will even see this

question 2 last part it ll be above the original graph
question 6 last part

http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Chemistry (0620)/0620_w11_qp_61.pdf
question 2 part c ii
question 4 part g

2, last part) sketch straight line to the LEFT of the original
6, last part) 5 cm3, just see on the graph.

2, c, ii) read the graph!!
4, g)
) temperature changes would be same/faster/owtte (1) metal in excess (1)/
temperature changes would be greater (1) lower volume (1)

LOL U CHEETR u copie d mark scheme
i dont get the part g
explain

hahaahaah! i no gradient method fenix

see, metal is in excess, so as much of it as possible will react and keep colliding and a faster temp change wud be seen.

question 1
question 2 c wat scale sems appropiate ?
http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Physics (0625)/0625_s12_ms_61.pdf
question 2 d draughts
question 3 how do i show i used graph just by linees and arrows right.
question 4 last part y do they put 3 lines for a few words i hate that

PLEEZ AND THANKU FENIX

u aske dfor them ( doubts)

THIS THREAD WILL ALWAYS HAVE DOUBTS UNTIL...........IM DOEN WITH IGCSE

Question 1)
1. connect A, B and C to the cross that is on the opposite side of each of them.
2. mark x in the middle of the region the three lines enclose after having been joint. then drag a line from this point to the bottom edge of the card.
3. Viewing line directly in front of card/ avoid parallax error/ view directly

draughts meaning a current of air
draw the graph, no?
i hate that too dey put that for ppl having a fat font. or mayb who hav a lot of cancellations. or if u wanna elaborate and cant b specific

guys
what is the answer for this question ??
thanks in advance

The elements in the compound are separated.
Sodium is basic. Travels to cathode, UI shows blue in that region.
Chlorine is acidic, and travels to the anode. UI shows red in that region.

Chlorine is not acidic. It is neutral.

Chlorine in water too?
