re: HSC Physics Marathon Archive wow thanks integrand .... (like, could you list some? will appreciate.)

re: HSC Physics Marathon Archive Any other 'scenarios' regarding the HSC exams?

re: HSC Physics Marathon Archive seems legit

nice facebook dp, reppin that juice

it's the last function. look at the formula you posted

yes, so let's take f(o),f(1),f(2),f(3).f(4) first and last is f(0) and f(4) we take 4x(f(1)+f(3)) then 2xf(2)

First formula should be h/3 not h/2 then it's the same thing as the second one you should take a look at youtube videos if you are confused by the different definitions/forms of the Simspon's Most people primarily get confused by 'odd' or 'even'. You have to establish this knowledge yourself by...

Another Q: What is the difference between a voltage vs time graph and a Current vs time graph? Assume initial position to be parallel to the field and an AC gen.

re: HSC Physics Marathon Archive I see where you're coming from. We can't technically examine the strength of the eddy-currents produced in P and R, since one is an insulator and the other has a break that reduces the size of the potential eddy-c. (I reckon there's a flaw in this question) Q...

For Q5 of the below attachment, how would you know whether to start on +I or -I for the graph

re: HSC Physics Marathon Archive I've asked 4-5 of my friends to try those relativity questions you posted anom. Most got the first three OR the last three correct. I think what confused them was t(0),m(0),l(0). Those variables with a (0) means "proper", so the actual length, mass, time...

re: HSC Physics Marathon Archive a) 11470.8kg b)21.79m c)2.29x10^-12 s d) 2.29s e) 229.4kg f) 0.872m

check ur formula sheet, if not, then textbooks. this is related to transformers

As for the explanation, we want to calculate the time on the spaceship (and we are also onboard). The time on earth relative to us is 1 hour. So the relativistic time is 1 hour. As a guide, relativistic time>rest time, so we should obtain a lower value (i have no clue what im saying, please...

v(primary)I(primary)=v(secondary)I(secondary) sub in and yeah (law of cons. of E)

re: HSC Chemistry Marathon Archive - Oh i thought it was the relative ease of conductivity through an actual wire, hence why electrons flow through yeah... - separated because each half-cell has a different reaction occurring (ox/red)

Not sure about exact dot points. But should prob mention: - Induction of current (F-law) due to changing mag. flux + motor effect - Back-emf (L-law) during propelling and braking - Mention the speed of rotation vs back-emf

re: HSC Physics Marathon Archive r^3/t^2=r^3/t^2 sub in values for earth and mercury. rearrange to get period then square root. ggwp if u used GM/4pi^2 i dont think it works. correct me if im wrong, but that is a constant specific to earth, no?

re: HSC Chemistry Marathon Archive That's a very good point. I've been doing heaps of trials now, and I feel the questions are quite specific and the marking criteria is even more specific. When I looked at past hsc papers, most of the questions targeted a variety of dotpoints at once instead...

re: HSC Chemistry Marathon Archive The feels for berry. :(
