re: HSC Physics Marathon Archive Simply 1 + a/g

re: HSC Physics Marathon Archive You reckon?

~40 marks lost on calc and MC? Exam seems a bit dodgy... But HSC exams are geared towards theory rather than calc. Assuming your conceptual understanding is solid, you can def pull back in the HSC

is this a question or just troll...

Interesting answer. So you reckon the rod will stop?

Re: HSC 2015 4U Marathon As Carrot stated. Also, to get to that degree of accuracy, surely theres a more efficient method o.o

Re: HSC 2015 4U Marathon how did you get to that root lol

Re: HSC 2015 4U Marathon have you done the locus involving arcs of circle?

Re: HSC 2015 4U Marathon In hsc, they dont expect you to algebraically prove this locus type q. this is one of those geometrical locus :D

Re: HSC 2015 4U Marathon ^ just draw the line between -2 and 2

Tbh, you're wasting more time asking around/looking for bargains/buying the goddamn book compared to simply visiting either Dan, nerd's or Spiral's resources and just grind the living out of those (this is exactly what i did, and out of say 20 books i bought, i didn't even attempt 20% of it lol)

Sounds like mif

^ lol I actually rote learn as I do more papers. This way, i consolidate AND improve my answers based on different marking criteria as well as being exposed to the variety of new questions that pop up now and then

I can totes relate.

re: HSC Chemistry Marathon Archive I feel like the salt bridge q. has been asked already KNO3 contains the K+ and NO3- that do not precipitate in ALL solutions (thus able to maintain electrical neutrality...) Could also talk about electrical conductivity and migration speed, but dont think...

Just tell your teacher that it's WAY TOO EASY - they'll give you another textbook to do (thats what i did, lol)

yup^

i reckon each ball represents 1s

which part specifically?
