Physics Unit 4 Exam discussion

[Apeman007]

For that field lines question, i didnt connect the loop because i thought the current from the wires going across to the solenoid would generate a field of their own and thus interact with the field around the solenoid/iron core. But then I only drew two lines going out the top and two lines coming in the bottom, which is technically only two field lines =\

[avram_grant]

you did not have to show lines going through the core as the question asked to draw 4 lines around the soft iron core

Hey everyone i got a mid-high A for mid yr, maybe a A+ for end of yr, and A for sacs
just curious what raw will i get?

[appianway]

Around 37?

high 30's, maybe low 40's depending on whether that A+ is a low/med/high and how good your physics cohort performs in comparison to other schools.

Mid As for sacs, B+ for mid year and possibly mid A for end of year?

For question 1. in the Light & Matter, would we have to refer to both interference AND diffraction to get full marks? I only referred to diffraction.

Shit, I only did interference I think, gg??

[methodsboy]

^^^^^^^^^^
i did both.. after discovering that i was rambling about the photoelectric effect and crossing about 4/6 lines for that question.... stupid VCAA didnt even put blank pages this year on the page!!
grrr

I did both.

GG, this thread is getting long, so im just gonna drop a post here to keep it going.

[Spluff]

I'm guessing we had to refer to both because it was a 3 mark question (even though only one clearly fulfills what was asked by the question). Fffffffff there goes my double 100%. (edit - itute only referred to one, maybe all hope is not lost).

[scope9]

itute says only interference, but if you explained defraction well enough then youd probably get the marks too

[vietsmista]

TrueTears id like to sincerely thankyou for providing us with that cheat sheet. Im pretty sure it has gotten me an A-A+, i cant find any errors. Does anyone know what a B+ and a high A would get me in terms of SS?

Ah crap is this ok?
I thought it was risky drawing loops cuz technically they did say "lines"
