    Where do you reckon a 92% raw mark will compare with the rest of the state?

    I concur. Doesn't change the fact that they love putting this type of shit in the exams -_-

    Question: In 1970 NASA launched Apollo 13, their third mission planned to land humans on the Moon. Half-way to the Moon a huge explosion crippled the spacecraft. The only way home for the astronauts was to fly around the back of the Moon and then fire the rocket engine to take the craft out...

    What about the EDS system in Japan? I understand the EMS system is purely electromagnetic repulsion. But I was under the impression that the EDS system levitated by means of the meissner effect.

    The relative motion I refer to is when you have the super conductor and then drop the magnet on top of it. Rather than falling and hitting the super conductor it will levitate i.e. stay suspended in the air not move upwards. Sorry if I'm confusing you haha

    Physics marathon (hsc)

    In order for magnetic levitation to occur, there must exist a relative motion between the magnet and the super-conductor so that current (and ultimately magnetic field) can be generated within the super conductor for the Meissner effect to occur. If the magnet is just sitting there then nothing...

    The "magnetic levitation" or maglev train in Germany utilises the Electro-Magnetic Suspension system to operate the high-speed, frictionless vehicle. This operates by employing the property of electromagnetic repulsion, where electromagnets are positioned on the track and the vehicle itself...

    Question: An astronaut embarks on a mission to the Andromeda galaxy travelling at 99.99% the speed of light whilst his twin brother remains on Earth. When he returns to Earth he finds he is now much older than his twin. By considering inertial and non-inertial frames of reference explain why...

    Re: General Thoughts: Mathematics Ext 1 Ah but for question 1 you must not multiply the middle term of the right expression by 2 :P

    Estimate your own ATAR

    ATAR calculator says 99.2 but I don't think it's very accurate haha. I reckon I'll get 96.

    What will this raw mark be aligned to?????????

    Remember that all EXT 2 students also do EXT 1 and without a doubt the majority ace it. Scaling depends on the average of the entire state and so I'd say you're probably looking at mid 70s to low 80s.

    General Thoughts: Mathematics Ext 2

    I felt this exam was one of the most difficult that I have seen over the past few years.
