Anyone else here suprised with you Engineering Studies mark. I am hella supprised that my mark was 90 and B6... especially after that exam.

Were any of the options on the IUPAC naming question even correct?

Ratios.

I started like that when I realised the question specifically mentioned calculations.. I went below "End of question" on the page so the marker probs be mad.

Re: General Thoughts: Physics What did you get for powerloss. I only got something like 1.6MW. So they would have to generate 101.6MW at the power station. Compared the others, this was the lowest to reach 100MW at the substation.

The last Q for Quanta to Quarks was a cracker.. Loved it.

Winning... I knew going over trick questions from past papers would help.. There was 3 that I had seen in past ones that I got tricked on when practicing.. Pays off :)

Does anyone agree with my reasoning behind choosing B for 8?

For question 8. Very similar to one from 2006 except it was current, not force. Look at answer. Doing it like that you get B as I answered.

0.2/Sin30

Umm isn't 8 A... The conductor is at 90deg to the field (its going into the page).. I swear I saw this trick from a past paper a few years back.

Re: General Thoughts: Physics Thats what I did (-cosx)

Re: General Thoughts: Physics Yep I got 20 = B. Changed wavelenth to frequency and used E = hf, changed to eV.

I said orbit, but to tell you the truth I had NFI and just wrote total baloney.

I actually haven't seen a question on this in the past papers I have been going over. If you have seen one please post it up. I would prefer a binding energy question over Standard Model of Matter question any day of the week!

So how do we find the amu of something with so much accuracy (I am talking 5 or 6 decimal places). In my textbook they use this accuracy in the data tables, are we expected to use this much accuracy if they don't provide us the info in a table etc. and if they do, how do we do it. I only...

on fml.. please no huge mark question on this

Okay, sample answers aren't a very good sample then lol

There was another post somewhere (shared across to the Chemistry section) however I have tried finding it without success (was on it the other day). Today I was doing a question and cross checking with the supplied sample answers. Data given was mass (2 sig figs), current (1 sig fig) and...

Yep, last year we did the Pendulum and projectile motion (which contained a little ramp and rolling the ball down thence off the table).
