... It doesn't make me feel better, he's made so many mistakes in that book that I've lost count + For part A is it really necessary to use the delta_y formula in this scenario?

Calm down I haven't done projectile in ages EDIT: You're argument for Part A is the same as what I said except I said that "assuming the speed stays the same" which means constant velocity which means no acceleration.

a) So when they say that the rockets are jettisoned they mean that they are shut down. So assuming that it travels the same speed back down to Earth you do: Time = Distance / Speed Time = 980 / 49 Time = 20 seconds b) Then you use the formula (delta y) = ut + 0.5at You want to find...

I had the same thought for the second and third image, but wow your interpretation for the first image was amazing :D I thought of it as the discovery of how reliant we are on the internet in this era to answer questions that we should be able to answer ourselves And I guess there is some...

Yeah of course Like every 2 hours I chill on BoS for a bit

I've been doing it for a week now and it isn't so bad :) My normal routine is 5 am - 9:30 pm but I've got to up my game for half-yearlies

Keep physics Like you mentioned it's low in content, but it takes longer to understand that content and apply it to different scenarios I hear that legal has more content than eco and bio O.o + If you want to get that 99+ ATAR physics will be of great help to you if you cant get a...

50 / 50 I do that for weekdays But for weekends I like to catch up on sleep so 10 am - 10 pm

4 am - 10 pm

Usually in the Option Module I've seen heaps on ethanol though (there was one in the 2014 paper)

You'll be fine I have my doubts on Physics and English :/

Lel I misinterpreted that My friends say I do that when I'm solving maths equations

wat

gg Economics They should have worded the "all other things being equal" as "ceteris paribus" (The only definition I remember from prelim eco lel)

Try to lift up Physics, Chemistry, Mathematics 2 Unit and Vietnamese Continuer's to top 5 then you're set :D

You're on your way to a 90+ ATAR But that doesn't mean that you should slack off because there will be people in your grade going all out to improve their ranks, so keep up the good work and don't give them the opportunity to do so :)

re: HSC Chemistry Marathon Archive As DrSoccerBall said you can't titrate two acids as they will not neutralise + The indicator depends on the acid and base combination being used. e.g. For strong base and weak acid it's phenolphthalein (We added the phenolphthalein to the standard...

I'm kidding TBH it actually seems like an interesting job :)
