2 free periods erryday? WOT ... (or perhaps you have shorter periods) and our school still doing conics rofl

Re: HSC 2015 3U Marathon so simplify first to get t=4ln(t+1) use log laws to move the 4 then equate and solve using polynomials

Uhh, the syllabus does not require you to specifically name scientists that observed/didn't observe the deflection. But your teacher is incorrect

Depends on the relative size of the CFCs. But I've never heard of a span of 50 years to reach it. From sources, it takes ~4-10 years Is this part of the syllabus o.o

Re: HSC 2015 2U Marathon lol, that mif Q

Both bad (HSC level) :P, although physics def more interesting as you research concepts in depth

re: HSC Physics Marathon Archive I think the question is looking for 'closest' - none of the answers define 'true' weightlessness. The definition of apparent weightlessness is seen in (A). Whereas (D) is likely the 'closest' to 'true' weightlessness

re: HSC Chemistry Marathon Archive For IUPAC ekman, is it really 1-chloroethene? There can be no other position for the chloride anyway, so shouldn't it be just chloroethene o.o

re: HSC Chemistry Marathon Archive Systematic - Ethene Common - Ethylene Preferred - (Doesn't matter) IUPAC (official naming) - Ethene I think

re: HSC Physics Marathon Archive What are you thoughts on this Q: http://imgur.com/uuZqLkY

Well, Josh said that the length of wire is 30cm and thus we no longer need to multiply by sin30. He further backed his argument as he said that the answer (to an identical question) in an independent paper was C

What answer did you get Fizzy? JoshMosh2 argued that it was C (apparently this was the case in an independent exam) - he said that we don't use the sin30 and simply do F=3x10^-4x 3 x 0.3 So I'm extremely confused as I was under the assumption that F=3x10^-4x 3 x 0.3 x sin30 Initially, the...

What is the answer to this : http://imgur.com/uuZqLkY Please explain why the answer is C, thanks

Yup Naplan accurately predicted my Band 2 english skills

Say I'm ranked 5th internally, whats the raw mark I need to have to state rank physics
