It does go lower....

no, look, when you supply heat to water it changes into vapour. the energy supplied is used to break the bonds, and so the temperature of the liquid does not change. this is the same if a gas is cooled, except that heat is given out.

8 a ii) hooooow? I drew the electrons ( negative) on the left and the positive on the rig, why is it up and down?

 

[Roselian]

My God, I think I lost way more marks than I thought. Struggling to remember my answers...

Aaargh, got the entire electricity question wrong!

electrons attract repel other electrons. this leaves unbalanced protons on the left side. electrons move to the right.

Hi, in the energy transfer question why did u multiply by 1 second and not 120s (lightning question)

 

[Abu mota]

And cud u plz post the beta particles question

 

[JOEJOE]

PLZZZ do variant 2 anyone i beg u

 

[EpicLol]

PLZZZ do variant 2 anyone i beg u

sry I cant my whole school only took variant 1

Hi, in the energy transfer question why did u multiply by 1 second and not 120s (lightning question)

because 1 lighting stikes in like 1 second.....or lower.....and then after 120 seconds the lighting strikes for 1 second again, so the duration of strike is 1 second, the time interval between two strikes is 120 seconds.... hope u understand now

awesome!

[yousef]

I have the question paper ppl, so if anyone has any doubts on how they did on certain questions, then they can post what they remember and I can repost the exact question to see if u ppl got it right

Just post questions/doubts/answers anything about physics paper 3 or 6

can you scan the other pages(questions)..please

not sure....
