# Edexcel IGCSE Physics Paper 2P 17th June 2016 --OFFICIAL THREAD-- watch

1. this paper was the easiest one ever done.....hopefully can get 55+ not less than 55
2. there was 1 question how the investigation can be improved.... 3 points
what did u write....

and secondly of that how to enable digital signals to carry more data..

1..by Multiplexing.
2.. by increasing bandwidth...

i wrote these.
3. the multiple choice question-how far do beta particle travel in air
4. What did you write for that question which was about improving the quality of the test.....?
5. nope,they came up...shame....lol

i checked my answers with My Physics Teacher.. he told i was correct.

i wrote these...

1. Take repeat of readings and average.
2. Avoid parallax error when measuring the length of pipe.
3. Avoid zero error when taking measurement

i m pretty much sure now . because i have confirmed with other site as well.
8. Can anyone write the mark scheme fr physics paper 2 pleeeeeeeese!!!!!!
9. 50 cm was correct...... if u have any queries . do ask me...i m pretty much sure i can figure it out

What did you write for that lift question....I was like the man experiences a shock beause of the potential difference that exists that causes an electrostatic discharge.....
11. Actually in my textbook it says beta particles can travel 5000 cm through air....so I wouldn't be too confident.
12. Can someone write the marksheme
13. conradliebers Where the mark scheme we're all waiting for youuuu
14. It's not 50cm.
15. its 50m
16. bbc bitesize says 'beta radiation travels tens of centimetres in air'
Spoiler:
Show
its 50cm
17. first i put 50m then i swtiched it to 50cm
18. is anyone going to make an unofficial mark scheme ?
Spoiler:
Show
I will if no one else wants to

do it plezzz
20. To improve the test can you say: use a more accurate/ precise ruler (mm), use same type of pipe?
