Hey

Im just back from the exam, how did everyone find it?
I thought it was ok, it had some hard parts n some easy parts
so who is gonna start writing solutions so i can see how i got on

[Nathan]

hmm...i dunno...i guess it went ok...i don;t think i got an A, probz a B

Anyway, my answers for the first 20 were;

1.E
2.D
3.B
4.A
5.D
6.C
7.C
8.B
9.E
10.C
11.A
12.E
13.B
14.C
15.D
16.E
17.B
18.C
19.C
20.B

The physics wasn't too bad although I can't really remember it. The rest of it didn't go so great.

Exam started, fine. About 20 minutes in the boy next to me (doing INT2) said "How come I always get the wobbley table!" to one of the invigulators. Then she gave him something to put under it and complained about her sore back. It wasn't really that funny but you know when you can't laugh things get much funnier. I was trying not to giggle for about 15 minutes.
Once I'd finally regained my composure a HUGE wasp landed on my hand and was really really scarey. Then it walked about on my papers while the invigulator tried to catch it. So after being scared I got the nervous giggles once again and was silently giggling for another 15 minutes.
Then I started needing a pee. Really really really badly. I have never needed one so badly in my life so I finished the exam and just about ran out of the hall. I didn't manage to check my answers though, and I hope my last questions are readable because my hands were shaking.

So although the questions weren't too awful (although I don't think I did too well on 21, that was when the wasp landed on my and put me off) I really don't know how I did. I didn't get to take out the paper either, which I'm annoyed about.
If anyone is feeling kind it would be very nice if someone scanned it and sent it to me. Then I might be able to compare solutions.

The first one was E and I didn't get any As until somewhere around 11 or 12 (I got two As in a row). Thats all I can remember.

[crazycat89]

it wasnt as bad as i thought... i have never liked taking info from graphs so imagine my annoyance at the first few question..grr lol

i thought it was easier than english anyway..

[Pyrefly]

Just got back too

I think it went ok...as you said there were some easy bits and some hard

I particularly didn't like the question asking what was the work done to move the proton. All I could see was the potential diff..no charge of protons. Ended up just shoveing in the charge for an electron in the hope that i will get marks for the rest of the question

And ya..i would quite like to see what answers you lot got

I did that too.
If the charge on and electon is -1 and a proton is 1 then they should be the same. At least thats how my reasoning goes.

I *think* that;s what they were expecting you to do, because there doesn't seem to be any other way to do it :S

and to start off section B..probz wrong, but;

21a] W=mgcos =2600x9.8xcos12=24900N (to 3sf)

b] F=24900-1400=23500 F=ma a=F/m = 23500/2600= 9.04ms^-2

c] v²=u² + 2as = 25+2x9.04x75 = 25+1356 =1381
v=37.2 (to 3sf)

First one?? wrong~~

[Nathan]

how so?
power is a scalar, weight is a vector

[Jade]

Hey,Yeh I thought it was ok
was a bit confused about the proton question so i just used charge of an electron aswell
Duno if it's right was just a last resort as I couldn't think of what to use.
Hopefully i have passed

ok, sorry, ｓａｍｅ　ａｓ　ｙｏｕｒｓ

i used the charge of an electron from the front of the question paper but i know that was probably wrong...
my multiple choice were : 1)E 2)D 3)B 4)A 5)C 6)C 7)E 8)B 9)B 10)C 11)A 12)A 13)B 14)D 15)D 16)E 17)A 18)C 19)C 20)B

[Pyrefly]

Ya i got E for the first one too

A- Aceceleration - vector, displacement - vector X
B- kinetic energy - scalar, speed - scalar X
C- momentum - vector, velocity - vector X
D- potential energy - scalar, work - scalar X
E- Power -scalar, Weight - vector correct


If thats not right...which one is wrong o0


(I was to slow to reply That means we all have 1 for sure )

[ice_illusion]

Ooh I remember that one.
I think I'll start writng down what I think I got for each and then draw it onto a grid and see how many I remember.

[Nathan]

lol

22ai] impulse=area under graph = 0.5x8e-3x70 + 0.5x2e-3x70 = .28+.07 = 0.35N

ii] didnt understand that one :S

iii] or that one :S

b] or that one

ＥＥＥ

i circled mine on the paper so i know exactly what i got

(I was to slow to reply That means we all have 1 for sure )

woot....1 outta 90

[SncZ]

i should have an A ... altho i feel really stupid for not realising what the charge of a proton was , altho i said ASSUME the charge of a proton is 1 and carried on so my answer for the speed way like 2x10^36 or something crazy.

overall i thought it was an easy paper.
