uac atar compass gave me 89.65 and matrix was 89.15🥲

true but theres no way youre ensuring enough depth for 9 marks in one page of recommended space when youre including formula derivations + diagrams for at least 2-3 scientists

the words of someone who wrote one page😂

i was banking on them not asking a trick question so i didnt put zero but flux is independent of current anyways so there would be an emf induced

probs a high band 4

0 for i since it won't conduct a current and whatever the emf was from 0.0-0.03s

yes by a bit i reckon

yikes 13/20 plusminus 1

my first line of working was literally ux = 0🥲

a lotta ppl on facebook got that

i did the same w diagrams and derivations n touched on the other scientists as well

on jah science ready is saving my whole atar rn

true but it becomes less and less accurate as the angle gets bigger so is there not a better way for those instances?

does anyone recognise the double slit formula x = λL/d? i can't find it on any hsc resource but i was taught it earlier this year from my teacher. all i can find is dsintheta = mλ or dsintheta = (m+1/2)λ. is that formula just a derivation of one of the two other formulas?

idk u probs can but i had to learn the whole syllabus over two days so my knowledge defo isnt the best but as far as the r value in calculations is it r = altitude of orbit + radius of earth or just r = altitude of orbit?

i tried it and i got the right answer when i used r = 6800km and 42000km but not when i used r = 6800km + radius of the earth etc. i thought the radius was actually the radius of the earth + the altitude; is this not true?

not entirely sure but positive work is done to move an object into higher orbits, so maybe use the formula for total energy which is E = -GMm/2r at both radii and then subtract to find the difference?

how likely is a short answer ac induction motor question for this yrs paper

from my teacher earlier in the year

does anyone recognise this formula: "ε = 2πfnBA"? it's the formula for the max emf in a dc motor but im not sure if we'd need it although i learnt it earlier in the year
