    who else is surprised with chem and phys?

    I got 91 for chem and was expecting 95ish tbqh, also 86 for phys when I was expecting around 93

    General Thoughts: Chemistry

    Correct me if I'm wrong, but aren't there probes that are able to detect nitrates/phosphates?

    Multiple Choice

    Thanks 11 - misread :( 20 - Took it as PbCl instead of PbCl2. Ah well, only 2 mistakes (or 3 depending on Q 12)

    Multiple Choice

    Aside from Q12, anyone want to explain to me why my answers are wrong? (Posted on the front page, seem to disagree with most answers on a few q's)

    General Thoughts: Chemistry

    Your answer is correct. I made a mistake (got 0.04 moles instead of 0.004) :(

    Except that would mean you start counting from the chain closes to the Cl, meaning it would be 2-chloro-3fluorobutane

    Multiple Choice

    They're not meant to :P. From my understanding, 2-chloro-3-fluorobutane should've been the answer, but it wasn't there.

    Something around 25 I think

    I was fairly confident with my answers too (most is the same), looking through differences now

    Multiple Choice

    In unviersity level, yes. From HSC content - no (Electronegativity takes preference over alphabetical in university naming)

    Section I - Multiple Choice

    10 wasn't the peak, ~8 was. If you use 8*10^-6 you get B.

    That tower question

    If you mentioned that it would accelerate at an accelerating rate, probably. (The value of g increases as the object falls).

    Section I - Multiple Choice

    I had 5C and 7B

    That tower question

    The earth spins at a (fairly) constant rate, the further away an attached object is from earth, the faster it moves. Therefore, it has a velocity relative to earth, allowing it to enter orbit through centripetal force. That's my understanding anyway

    Re: General Thoughts: Physics This lol

    That tower question

    The mass on the tower on the equator would have a higher velocity than earth's rotation, allowing it to stay up and orbit. The mass on the tower of the north pole has no velocity relative to earth though
  18. S

    That tower question

    Yeah, that's pretty much what I had, since it would be released at the same velocity of a geostationary satellite.
  19. S

    That tower question

    Did people put the object dropped from the tower at the equator will orbit the earth, and stay motionless relative to the tower? I've spoken to 30ish people about it, everyone had something different :(

    Re: probability question You'll should get them :)
