Hey, my lichess username is wrong in the form. It is actually truss_4. Can u change it. Thnx.

let jack be J and Ruby be R. Hence: 1) J = 2R and 2) R+25=3J As a result, you can solve for J and R using a simultaneous equation where: R+25 = 3*(2R) => Therefore 5R = 25 => Therefore R = $5 Hence J = $5 * 2 = $10 initially As a result, they both had $15 together initially. Hope this helps...

This is good advice (although it may be a bit heavy in work) but I certainly don't agree with the last one. I certainly think spreading the time evenly is NOT stupid and you can certainly manage a 99+ without 6 band 6s (4 mid b6s and 2 high b5s and got a 99.25 in a ~325 ranked school). But...

lol. I feel like a dumb idiot even though im starting uni in a month. :)

79/100 is not bad especially as it is like the beginning/middle of year 12 (at least in terms of assessments. My year 11 physics first assessment was like 10/20 (prac exam) and I really did hate the boring stuff until electromagnetism but by the end of the year, physics really does pay off. If...

This is best done using vector notation. Consider the vectors XY and XZ as given in the coordinates. Therefore: XY = Y-X = (2,λ) XZ = Z-X = (λ+1,2) Hence, if we take the dot product of XY and XZ, we would get the following: XY . XZ = (2 x (λ+1)) + (λ x 2) = 4λ + 2 = 0 (As a dot product of 0...

Yep. Bad study habits (Got a bit carried away). Anyways - the best thing for the report is to start it as soon as possible which is as soon as you have the data. Also I strongly, strongly suggest u finish everything by the end of term 1 so that u have enough time to actually study for the HSC...

So, sadly ur not assessed on ur report... I just went a bit ham with it which in hindsight is way too much but I was having some real fun with it (specially when asking some other people in the field about their thoughts)... enjoyed it too much thas all. The bell har thing is the model and it...

Assuming u have finished a scientific research proposal, the next stage for me in finalising the experiment involved answering a few key questions: 1) Did I understand what the literature is telling me and can I make a decent question out of it? 2) Can I add or verify anything in the existing...

That is a good topic with lots of recent accessible papers. Maybe look at modelling factors for diseases like malaria in developing countries (first thoughts but would be an interesting suggestion.. might be too difficult) - also I am willing to help if u need to.

hmm for q10.. i dunno if it is 14 just because of the fact that I have tried like 10 different combinations of these 9 dots and a max of 8 combinations is all I found. Might be wrong but I'm just trying to help (I have no real proof - might be pigeonhole principle who knows)

It is precisely "Modelling the Australian Wildfires’ influx in CO2 and soil runoffs and its impact on the shell formation in marine organisms". I have linked it below. (it is ok but not the best) [edit: just noticed Etho_x ur doing science extension. That is nice... good to see more people not...

Most teachers be fudging (especially in our school) or why would they wanna be doing eduction with that ATAR, I wouldn't know. (obv opinion bcs most people I have seen are not passionate in teaching just had a really trashy atar but ur case.. i cannot speak for)

not 6 hrs a week - 12 hrs a week but ok (yeah well it isn't cap because I had other issues and didn't have time to study. lol.)

99.25

If u enjoy it, I will not question it but with an ATAR goal of 90 - you would be aiming real high. Take care of urself a bit bro... post-hsc, I was drained as hell because went into crazy study mode for the hsc similar to how u are doing consistently now (my reasons being different because of...

Etho_X lol. I studied 12 hours a week (not a day)... isn't that a bit much - there are other things to do in life, right. 6-8 is okay but still overkill...

Hmmm... I think this explains it a bit better. Think of the atomiser as a spray bottle with a salt solution where the metal cation is dissociated and it is an individual atom encased within the "atomised solution" - like spray droplets with ion atoms. What the atomiser does is spread it over the...
