Can someone explain to me how is the answer clockwise?
Right hand grip rule: thumb points in the direction of NORTH pole, fingers thus curl in the direction of current. Hence, anti-clockwise.
^
can someone also go over the right hand grip rule or curl rule or whatever it is called for determining current direction ( I get the LHPR but I don't get the other one )
*EDIT*
The magnetic field direction is up as you said because the magnetic field lines leave from north to south I get...

Also emission time
Classical theory predicts relatively high emission times for low intensity light, it instant though...that is just another aspect
I saw there's a collection of HSC Advice, here's a collection of mainlywhat NOT to do
1. Don't get bummed over one assessment task and be like gg fuck hsc and quit everything (went from a high band 5 --> band 3 or low band 4)
2. Don't get cocky, if you are ahead of your class MAINTAIN that...
re: HSC Physics Marathon Archive
Just think about it in terms of forces...there is a magnetic field force (unknown) and a gravitational field force (this is known and equal to f = ma aka mass on balance * 9.8)
thus F(known) = Bil(B is unknown)
etc..
No aligning is completely different. Aligning refers to the process your raw mark in the HSC exam undergoes. So if you get 63% in the chemistry HSC exam, this 'aligns' to a HSC mark of say 78. Thus, your external HSC mark is 78. What you get internally is determined by your cohort's performance...
I write heaps of jokes in my answers
For the general maths HSC I wrote definitely vodafone rates when calculating the speed of this download thing
In my chem trials I didn't know this question so I just crossed out some words, reworded it, changed the marking scheme and answered it. Teacher...
