    Circles

    good effort:D and yes its a lil dodgy, especially at the end where is says therefore 3-10 has been rotated 90 degrees about 0 (centre of clock) therefore 12-7 and 3-10 are perpendicular. but yeah its a dodgy question in the first place

    Circles

    Actually there's another two i don't get. 1. Prove that if two tangents are parallel then the line joining their points of contact is a diameter 2. If a parallelogram is circumscirbed about a circle (ie. each side is a tangent) then by listing equal segments or otherwise show that the...

    Hehe, the strangeness is what strikes me. Guess my lateral thinking ability this is mediocre. I tried to draw a diagram and attach it, but it was too big(i did it in paint).

    What are my chances?

    Selling those stuff heh? Damn, i should've done that a long time ago. I guess all these activities you would need to enquire into the school student body? As for the unis, i not leaving sydney, chances are the university for me is unsw. I don't know about newcastle, isn't that like far and...

    What are my chances?

    Yes i'm in yr 12 this year. What are charity works would you suggest or know of? And is med really the same standard throughout all unis? I only ever thought of Unsw. I guess there's still unversity of western sydney and macquarie

    i've tried connecting the lines to the centre but i can't establish a relationship to find the angles which they intersect (which is suppose to be 90)

    What are my chances?

    Jobs? i did get a pretty good comment for work experience. But other than that i haven't been doing anything. And i haven't been doing charity work because that usually gets organised by perfects and stuff. So i have no extraciricular activities to put on. Am i doomed? what could i do? go up and...

    What are my chances?

    Ok, i want to get to med at Unsw I think i will get a UAI of around 99.4-99.8, though i think my projected will be lower as i didn't put in enough effort earlier. I am not a prefect or part of the student council and rarely participate in extraciriculum activities. I'm pretty sure that I can do...

    Please explain

    I'm still here reading and getting a little confused please clarify each point 1. are electron replaced or just moved around in the conductor once a current flow past? it is same for DC and AC? 2. i recall abdhoo saying something about the current is 99.9% electrons. What makes the tiny...

    Please explain

    Does the flowing of electron change the neutral state of the conductor and the power source( if its possible)? I mean where are the electrons going?
  14. L

    Please explain

    in electrical conductivity, i know electrons are allowed to flow. Say the electrons in a metal are electrons (A), and the electrons in the electrical current electrons (B). When the electron flows to the metal and out to another conducting surface, do the electron get electrons (A) flow out or...
