Ahh crap, i wrote b) in light years, instead of years..... Oh well stupid mistake. Hopefully they wouldnt mind ^^

Dw, man i used a speaker to :D . yes its an appliance, if TV is one, why isnt a speaker? Yep, electrical energy -------> sound energy And by heading i ment TITLE. You had to have one :) that was like the first thing i wrote just to make sure.

This is how i done that question. First you look at the intial pH of both acids, i.e BEFORE the titration. 1 had a ph of 2, and the other of about ~1.2 or smthing. then you use the formula [H+] = 10^-pH To find the [H+] concentration. Obviously the acid which had ~1.2 pH was more concentrated...

Wooh :) based on your answers and the discussion of the thread im most likely gonna get 80+ raw :D just stuffed up that 34.5A by using 2I question but should get some marks, ohh and i left the projectile motion 3 marker, that was like impossible for me. Apart from that everything seems right :D...

Hmm. just noted this... yep seems like it is rotating the wrong way.

lol, forgive my noobness.. i didnt see the quote button even tho it is like the biggest button on the page.

I got X pretty sure thats correct

We had a similare question in our trial paper. name 2 appliances in household or industry in which electrical energy can be converted into more useful type of energy. Well in my trials i wrote oven, converts electrical into heat energy in order too cook food, and in industry an electric motor...

hmmm, i dont think so, considering the amount of space that was given. We had something similare in our trials, i got full marks. I'm thinking 1 mark for each appliance and the final mark given for a heading for your table :D yep i remember losing a mark in my assessment for not including a heading

most my answers are similare, and i also got the same as you for the tourque t=fd d = 0.3 To thecorey0 , i got the same frequency as you, yes frequency has too be quite big, since speed of light is soo large, and wavelengths are relatively small. Also wasnt question 23) b = 34.5A , i found out...

Appliance - Television Speakers Transformation = electrical energy converted into sound energy use- provides sound for the pictures on televisions. Something like that for 3 appliances

Yep, got that too. :D ohh and i seen the projectile motion with the plates and i was like :o Skip, But that was the only one i skipped, the rest Wasn't that hard hmm yea thats what i thought, arent real LHC the strongest magnetic fields on the planet.... use around 10T? i seen 0.025 and got a...

5) is C F = GmM- d^2 You guys have to realize.. Distance DOES NOT CHANGE! if distance would change with orbits, and due to eclipses, then why is the value of the distance from the Earth to the Moon, or the distance from the earth to the sun a constant, i.e 1 AU Ok wait, i read the above...

Lol, i proceeded based on our syllabus. because our syllabus taught us the most suitable way to convert nitrogen into ammonia is by adding hydrogen... which is the haber process And because there was no quesiton on the haber process, i thought u had t use it... ohh well.... guess im wrong...

Lol, to be honest, i forgot if it asked about acid 1 or 2, but i definately done KCL as the salt. and i wrote phenolthalien indicator to be between 7.5-9 is that still correct?

^ +1 Same here, except for eutrophication i wrote how it kills aquatic life, and chokes water. it was only for 2 marks, so im guessing mentioning wat eutrophication is and what it does would get u 2/2

yes that question was relatively easy. My salt formed was KCl Hcl + KOH ------> KCL + H20

i got the ethanol mass correct, and also the emf. but for nitrogen content in the bread .... I got 0.8% anyone else get this?

+1 i wrote most of the correct stuff comparing with use :) makes me feel alot better since i stuffed up MC Anyone did anyone find about 6 lines for a 6 marker way too less? Overall, i think they could have given us much more space to write our answers

Yep this was a really screwed up multiple choice... And what did every1 get for question 14, i done the calculation and got A, but thats not what most ppl got.... Also Question 8 would be B would it not? CO3^2- makes a percipitate with pb^2+ But most ppl got A.. hmm
