    HSC Results and ATAR

    hey, so we get out results 2morro 6am , yes everyone is nervous im mostly shitting it, the fact that im probably gna get told of by the rents. Anyway, when we get our results, we only get our aligned HSC marks and bands Is there a way to accurately estimate ur atar with them? Would you just...

    galvanic cells

    the liquid junctions represent a n-type and p-type semiconductor, most likely in liquid state. The junction, when connected to a external circuit causes electrons to flow through the circuit once its exposed to sunlight (UV radiation). This is how they make solar cells. This isn't in the...

    Wow, you got it spot on... Picture memory? and and if you could be so kind, to also post the answers :D Dimensions you had to use your Rules... plate to plate = 1.6D point to point = 1.8D diameter = 0.8D Ect, ect, ect......

    i think i got around 18mm diameter... I know i got that for a question, but cant remember clearly if it was the diameter one.. but am pretty sure it was

    Why did you divide or multiply by 2? When you converted mm squared into m squared Did you do x 10^-3 OR x 10^-6 because its ment to be x 10^-6 hmm... im pretty confident i got it correct, but there is a possiblity of a stupid error

    .. Dont u reckon 50 smthing diameter is a bit too big? And for the Drag question I did: i think you where given Drag to Lift ratio 1:8 so Drag/Lift = 1/8 Hence, Lift = 8 x Drag Then i did Cos 'Theta' = lift/weight Weight and angle was given so i found out lift. Then used Tan 'theta' =...

    Diameter was 18mm i think by memory? And yes True length WAS 8m.. Ohh and can someone post up both the correct answers for the drawings? :D That is where i reckon i lost most my marks, the rest was relatively easy :)

    Engineering Marathon

    I would talk about hybrid vehicles.. eg electric and how an AC induction motor can be used to improve energy efficiency btw, this question is really vague, as its asking for 'improved energy efficiency'... in reality electric, hydro Solar etc.. at this moment, can now where near provide enough...

    Engineering Drawings

    umm in our course its only orthogonal, oblique, and isometric... but i guess its half and full sections that let me down, i dont know why, but i cannot understand complex Drawings.

    lol, Nahh i wouldnt say that... for assessments yea.. the top 5 are really good.. but for exams Its heaps competitive the whole class... maybe not like 2-3 ppl that are ranked the lowest
