Whats a step-wise function? Like what if a hsc question was like explain why frequency increases with photocurrent...surely that isn't what u're supposed to give right? @carrotsss (u both hv contradiciting things so thats why i tagged u)

Millikan oil drop is module 8, so maybe thats why you don't know. But using F=qE and F=mg, equating it and making d the subject (E=V/d), you get d=qV/mg. Subbing in known values should get you the correct answer.

I mean essentially you just want to change the LHS algebraically into something which you can use your n=k/assumption. Then simplifying that should give you the RHS. Do you have specific examples? Usually induction questions are pretty straightforward.

could you perhaps explain why photocurrent increases with increase to frequency? Carrots said it doenst increase so im kinda a bit confused as to who to listen to

hes the og

i need to catchup, do phys mod8 over the holidays (more than halfway through) and also i got to do maths (which i hvnt even started, hv to tmrw tho cus lesson is close)

FRFR i now go to my parents workplace to do work :) its after hrs so no ones there its just me (now imma go study phys my break is over :( )

ur letting a yr11 dictating what u write

idk it was shared on our schools cohort drive lmao

just wanna make it clear THIS IS NOT MINE i hv nothing to do w this

wait i have a good one give me a sec

this guy studies 6hrs everyday btw

cultural is good a lot of people do it.

ha imagine trials keep the grind going ✊

here goes my rant o_O english went smoothly, probably the only subject I feel like I couldn't have gotten any better. tho i didn't do any practice, i just sat the test on the day lmao (idk if that was a good idea, i just cbf cus i spent the previous wk purely on memorising) maths was ggs, 3u i...

It's just part of the binomial theorem, the nc3 and nc4 is always there for any expansion, same as nc1, nc2, etc. It's another way to write pascal's triangle, or (n 3) ( except it's meant to vertical that's why i did nc3 instead)

So it's pretty much just binomial expansion. Do you know how to do it?

So we can rearrange what's in the bracket to make it simpler: (1+y(x+y))^n Since the question asks for the coeff for x^3y^5, Expanding it using binomial theorem you will get something like nC3 (y(x+y))^3 + nC4 (y^4(x+y)^4) But you realise the only term that works is nC4 (y^4(x+y)^4 since the...

I'm not sure what formula you used to find 71.62, but heres my method Use this formula, this is the force per unit length for a parallel conductor. This question is asking you to find current. Rearranging for current and subbing in known values you will get I1*12=225. (Here I've assumed that...
