    Physics marathon (hsc)

    Eh, it wanted to know about its launch point so I just threw that at them. OHHH now I see the diagram. S= Sun, the arrows earths orbit and the odd thing is Mars or the Star?

    Physics marathon (hsc)

    a) A natural Earth 'run up' is available before launch. As the Earth rotates rapidly, a rocket posesses a large easterly tangential velocity at launch. This rotation is strongest at the equator, minimising the values of g and providing the fastest tangential velocity. The higher the altitude of...

    Cheers Lads :D
  4. K

    Physics marathon (hsc)

    gather, process and present secondary information to discuss how shortcomings in available communication technology lead to an increased knowledge of the properties of materials with particular reference to the invention of the transistor Yeah I dont have any notes on this and HSC online is...

    Chemistry and physics study

    I normally go through my syllabus notes, resummarise all of them further onto a4 sheets of paper, then attempting past papers. Read my notes few times through each day. Then just before exam you can read over your a4 sheets that you prepped earlier. Thats just how I study

    Well actually this is a syllabus dot point Process information to discuss Einstein's and Planck's differing views about whether Science Research is removed from social and political forces Planck stayed with Germany and Einstein argued that his work should only benefit society blah blah blah...

    [HELP] Einsteins Relativity and Light

    Michelson Morley experiment threw Aether theory out, Einstein suggested Light was constant, used his thought experiments to explain this, however thought experiments are limited to common sense. As time developed this theory was able to be proved true using the flying of atomic clocks to...

    Physics marathon (hsc)

    It probably will, that would be how you would conclude it. So add, however the body will encounter air resistance resulting in thermal energy decreasing its orbit and returning to Earth. But anyways, this was just a thought experiment of Newton, that if he launched his cannonball fast enough...

    Physics marathon (hsc)

    With that cannonball question isn't that just a Newton thought experiment to explain the concept of escape velocity? If the cannon is powerful enough to launch it to the poles then due to the curvature of the earth and the excessive speed of the cannonball, then it will never return to earth and...

    past papers!

    Im a represenative for the Prince of Ghana Foundation of Academia and I have just uncovered a stockpile of very good Papers testing physics. However Ghanain Legislation requires Collective acceptance of this stockpile so If you give me your email address, your name, credit card number, CVC...

    Part-Time jobs!

    I work in fastfood, and because my store is in NSW's Lowest socioeconomic region work is always interesting with all the characters you meet, such as people complaining that their 21 piece bucket has 22 pieces in it, requesting a formal complaint because another customer walked in while they...

    What are you going to do the moment you finish your HSC ?

    Walk out of SOR, Jump in the air, everything will freeze and fade to black and white, then my school photo will appear on screen with the quote "Keelan went on to university and became a bank teller, he married his childhood sweetheart and had 3 kids. He now lives in his home in Philadelphia...

    Sections III, IV - Extended Response

    I was kinda assuming it was going to be nothing like the Specimen. Lucky I can bullshit and make up reasonable stats, Told BOS that Volkswagen promoted its new fuel efficient passat with footage of terror and war then the closing quote "Berlin to Warsaw on one tank" and how it was banned by Govt...

    Section I - Multiple Choice

    We do it in Finance section. Global Influences or something. If you had general understanding of currency and reasoning you could deduce that three were bad one was good

    Section I - Multiple Choice

    Let me stress now that my reasoning may not be correct, this is just what I thought in the exam. 6: B It was obvious not to be C or A. I went with Marketing because they developed an item that I assumed customers would want, whereas Selling approach businesses make whatever they can and try and...

    Section I - Multiple Choice

    I thought we got over this argument :( Honestly chaps lets leave it to the board, Anyone wanna play Fifa, PS3?
  20. K

    Section I - Multiple Choice

    Exactly, its only question 6, it should only be a 3-4 question tops. But heres something to ponder. Why was the business developing a shirt that doesn't stain or get crushed? DISCUSS
