So there is a current carrying wire which produces its own magnetic field. Relative motion between a electromagnet and a wire causes emf, the direction can be calculated through Fleming’s left hand rule, where the index finger is the direction of the magnetic field from the electro magnet and...

if your interested in what marks you roughly will need to get a 95 go to talent 100's atar calc and the column that says atar equivalent is what the subject actually would be equivalent to if it was an atar.

eng and modern scale the best out of those subjects and due to legal and business's poo poo scaling you will have to do a better in these subjects to get a 95 atar equivalent.

this happens with every HAST school, it just means that you sit the exam at your preference 1 school, and the other schools just take the data from when you sat it at your first preference.

if your good at selective tests style exams do the HAST, i think there are also other good schools who offer positions based on HAST. If not i would still suggest putting one of the HAST test schools down in case you get a good percentile, because they dont care about your preference placements.

once u learn math properly u never forget.

This is the 2021 integration marathon thread, as i have noticed users submitting integrals on previous year's threads. I will start off: 1/(x+x^6) sorry for bad formatting

He didnt integrate, he realized it was a semi circle and after a sub and then he used the area of a circle formula to find the area beneath the curve. This is just an instance where it is easier to use properties of the curve rather than integrating it.

ye sure, but for clarity they still have concentrations.

quick proof: c = n/v= n x 1/v = mass/MM X 1/v = m/v X 1/MM = 1/MM X P. where P is density which is constant for solids and liquids and 1/MM is a constant as it is molar mass which is fixed. Thus concentration is constant. sorry for poor formatting.

well actually they do have a concentration, its just that having a constant concentration in the eq constant provides no additional information so they just disregard that info.

ye when i watched the mit integration bee i felt it was an easy expansion + reverse pro rule, iirc neither of the contestants got it right.

no i mean a hsc mark of 94 will get you a 99.95 provided that all your other subjects give you 99.95 atar equivalent.

Be careful of where you allocate your time, because even though a mid to high e4 in ext 2 is desirable the effect of scaling becomes less and less iirc 94 in ext 2 scales to a 99.95. Therefore your time is better spent on weaker or worse scaling subjects.

series and sequences is easy enough to finish in a couple hours, so i say just learn series and sequences first.

I didnt pay attention in science from yr 7-10 but just self studied mod 1 for phys and chem in the summer hols and it was enough to do well.

teachers dont care how you present info in the sciences. my teachers have said that for longer response questions even dot points are accepted. this is unless the question instructs a procedure e.g. flowchart.

I would suggest to look through past papers of top 10 schools and there is usually marking guidelines with comments on where there are common mistakes among students, i did this and just practiced those sections prior to doing the module in school. So you could watch vids on those sections.

As a whole for phys and chem, I would say you don't need flashcards. However, there are certain topics that you need to ROTE learn, e.g. hydrocarbons in chem.
