Physics Unit 4 Exam discussion

[avram_grant]

i agree - lots of theory but very similar to past papers...

[dylanru]

It was certainly longer than previous exams due to the wored explanation questions however it was no more difficult. I found it pretty easy especially electric power and light and matter was easy if you had the theroy down. Anyone got deailed study answers?

[Slappo]

for once.. i used my cheat sheet

haha it was good exam, defs harder than unit 3.. but if u know ur theory back to front especially with section 2 or with a decent cheat sheet.. not that hard =D

too many "explain" questions. i wrote on every line i could lol.

did anyone else get a massive number for the energy of the photon? like 8000eV? i was getting very worried.

[m.hudson.1990]

Yeah same here...i got just under 8000(8.9x10^3) i think...triple checked it...its right

[avram_grant]

i got 8.87x10^3 eV

[toomoo]

True grant!

[m.hudson.1990]

yeah that was it...just under 9000 was what i meant to say

[avram_grant]

does anyone have suggested solutions for entire exam?

8.9*10^3

Good exam I reckon.  In my opinion, a great way to separate the A+ students.  Instead of making a dodgy paper (like '07), they put more "explain" questions in.

we didnt have to put it in sig figs did we :S
apart from the question where we were required to.

[avram_grant]

did anyone get 498V after its stepped down?
