    Questions on Advanced Science (UNSW)

    Thanks for the replies all, I was just concerned because I was hearing requirements of like over 90. As for major, I was planning to do physics.

    Questions on Advanced Science (UNSW)

    Hey guys, recently I've been feeling a bit lost (and a bit discouraged) about my course choices for University. I had been pinning for Science (Advanced) for a good.. 6 months and plan to do a dual degree with Commerce if possible. My first concern has been the job prospects. I've read...

    Any way to learn Chemistry Course in a week??

    Old topic but... that's hilarious. No wonder he didn't get good marks - have you SEEN the surfing answers?

    2007 HSC Solutions

    Couldn't find them - I'm trying to look for solutions to this specific past paper: http://www.boardofstudies.nsw.edu.au/hsc_exams/exam-papers-2007/pdf_doc/info-process-tech-07.pdf

    Two Relativity Questions

    Thanks for this and everyone's answer! Upon further research about this, I think I grasp the idea now - that acceleration factors into how SR works. Whilst browsing I found a website that definitely helped in any questions I had about SR...

    Two Relativity Questions

    The twin paradox does seem to make sense for the reference frame for a person Earth, as they would view the person on the spacecraft as aging less. However, as you mentioned before, the person on the spacecraft would see a person on Earth age less, i.e. from the reference of the person on the...

    Two Relativity Questions

    Sorry to be that guy that picks out every little thing, I just really want to understand this XD Well obviously everything doesn't return back to normal when a spaceship returns back to Earth - the people who have travelled will have aged less (e.g. growing a small moustache compared to a...

    Two Relativity Questions

    So this would mean that if the person in the ship experiences 1s, an outside observer would experience roughly 2.3 seconds. Scaled onto this example, the person on Earth would be experiencing less time then before (i.e. from 2.3 seconds -> 1 second) BUT NOW rather than the travelling person...

    Time Dilation Confusion :S

    What you're implying is that the time aboard the ship (2.3 seconds) is larger than the outside observer time (2 seconds). This means that for every 2 seconds of outside observer time, 2.3 seconds would pass for the traveller. If this were scaled up i.e. 2 years has passed for the observer and...

    Two Relativity Questions

    I came across a problem that I can't seem to fully understand: If, for example, a person was travelling at 0.9c relative to the Earth (or a person on Earth), then according to relativity, the person moving would experience a "slower" time then the person on Earth. However, in the reference...

    Need clarification for an acceleration-time graph on a rocket launch.

    I've been receiving some conflicting information and just wanted to clarify. For a rocket launch, is the acceleration-time graph a linear increase, or is it an increase at an increasing rate.

    Year 11 2014 Chat :)

    Does anyone know the confirmed dates of the 2015 HSC? Been looking around but haven't got a clue. Cheers in advance.
