    How are YOU studying for the HSC trials and when are they?

    I already have! :) I'm a teacher at a school. Interested in students' study habits I encourage it! That was one thing which helped me during my HSC. I definately would not have gotten the marks which i did for some of the subjects if i didnt have a tutor. I would love to see a kind of...

    Air Resistance

    Dude.. think about that equation.. The density is referring to the density of the medium which the object is travelling through.. So, really.. Drag force is independent of mass of the object itself. BUT If that is so.. Then all objects the same "shape" so to speak would experience the same...

    How are YOU studying for the HSC trials and when are they?

    My school is having the trials week 3-4, Physics is Wk4 thursday morning. Having seen the independent trial paper, which most public schools use, it covers pretty much everything.. I for one am not going to use it, cuz i think it is a bit easy and i have a notorious reputation for making hard...

    Trial Studying - Need help on a QN

    cbf doing it, but you need to use the time dilation formula and rearrange it to make v^2 the subject.

    Commodore...Falcon...Accord Euro...Aurion

    200kw Aurions are shite, sorry. My car smashes them. I have an AU falcon, my car even beat them when basically standard. Seeing as you have the pic of the XR6t, then you should know that the new xr6t produces 270kw and over 500Nm torque. I personally prefer the B-Series xr6t's cuz the turbo...

    Air Resistance

    Well, yes it has an effect. Of course it does. With the HSC syllabus, they are using the "simple gravity pendulum" which actually assumes no air resistance and friction. I would say that air resistance definately is a valid response, but seeing as this can be said for just about every single...

    Help About Amplifier and Sub...

    Should be able to. Is it a 2ch bridgeable amp? You can operate it in "tri mode" but you will need passive crossovers.

    How much do you spend on petrol a week?

    Depends largely on the car. I have done a bit of work to my car and have had it tuned to advance the cam timing to take advantage of the extra purity in the petrol. In a normal car, with U91 you may experience a small bit of 'detonation' due to the low octane rating, especially when the...

    Do you like Holdens or Fords?

    SS are v8's tho, i mean 6cyl :) SS Commo with a blower still wouldnt run low 12's down the 1/4 anyway and i doubt they would get 300 @ the wheels! on the xr6turbo forums there was a heavily modded xr6t that ran mid-11's with over 300 at the wheels going for $18k, un freeeeknbelieveable! I did...

    How much do you spend on petrol a week?

    1 tank per week, which is around $75 (BP Ultimate 98 FTW!)

    Do you like Holdens or Fords?

    Ford anyday! You can buy a 300rwkw BA xr6t for under $20k. Cant buy a decent looking holden that will run low 12's for less than $20k My general rule is Fords for 6's and Holdens for 8's, i love the Holden v8s.

    Help with Quanta to Quarks!

    1. Lyman series is not in the new syllabus, dont bother. 2. Particles orbiting a central point (i.e., nucleus) would continuously emit EMR due to change in velocity (hence acceleration) around the nucleus occuring all the time. Acceleration requires a force, a force can be equated to work...

    Balmer-Rydberg Equation Questions

    Looking at the syllabus there are two main points: -Process and present diagrammatic information to illustrate Bohrs explanation of the Balmer series - Solve problems and analyse information using the Balmer-Rydberg equation So i actually suppose you could be assessed on different initial...

    Balmer-Rydberg Equation Questions

    to find the radius its simply the following: n^2*r so for n=2 the radius would be 4x, n=3 would be 9x and n=4 would be 16x. You are not required to know this, nor the derivation. Aerath, why did you use the initial energy level as n=1 in those questions? The HSC syllabus is only concerned...

    Very Confusion (Multiple Choice)

    Using following equations: Time of flight = 2*u*Sin(theta)/g As theta moves from 0-90 Time of flight increases to a maximum --> 50 degrees has a longer time of flight Range = u^2Sin(2theta)/g As theta moves from 0-45 Range increases to a maximum, as it falls from 45-90 it falls to zero...

    Anyone gonna go for it? I got one a few years back, has been quite good :) I sucked at the interview, but my marks were good enough to get me through :) I even got my photo taken for all the bloody flyers everywhere. All the kids at my school give me shit! It's definately worth it if you...
