PHYSICS 2 UOM EXAMS (640-112 / 640-132 / 640-172 / 640-182)

[dcc]

From what I can gather, the subjects:

Physics 2: Advanced (640-112)
Physics 2: Physical Science & Technology (640-132)
Physics 2: Life & Environmental Sciences (640-172)
Physics for Biomedicine (640-182)

had their exam today (this morning).

How did you guys go?  I took 640-112, and I enjoyed it.  Some of the questions I did the old 'figure out what the area is by working backwards from the answer' trick, but most of it was cool

THOUGHTS?

I did 640-172 and found it rather interesting, especially the one about the magnet through a hole.

Is that induction?

[Gloamglozer]

What's the "figure out what the area is by working backwards from the answer"?

[Edmund]

Thanks to kamil9876's response, I was able to answer the magnet in hole question.

[Ahmad]

What's the "figure out what the area is by working backwards from the answer"?

More generally he's probably referring to the problem solving strategy of working backwards.

I did 640-172 and thought it was Ok. It had its easy questions and its hard questions.

Basically we have this law (Gauss' law), which basically boils down to:

Now, if I know what equals, I can write down a value for such that is equal to !  I did it on perhaps 3/4 questions where I couldn't figure out how to do it properly.

I did 640-172.. some easier questions but quite alot of harder/unexpected/unseen questions. there seemed to be alot of "proof" type questions, which I didn't like... Overall, don't think I did nearly as well as last semester
At least I can say goodbye to physics forever!!!!  

Yeah i have to agree with you on that one. There were a few questions i wasn't a fan of!

There was one on Ampere's Law (or not?). I wasn't sure how to derive it, only knew how to do it for Gauss' Law... And probably because I didn't knew the formula to magnetic field through a solenoid? Now what am I talking about  :idiot2:

Also, I forgot how to do the Sun/Earth radiation question and the nuclear radiation question (last part)...

[iamdan08]

Yeah that ampere's law question was not fun...i had no idea where to even start! lol.

[Edmund]

Which 172 lectures were you guys in iamdan08 and monicak?

[iamdan08]

I was in the 10am lectures. Do you think most people would have found that exam challenging?

Aha I'm in the 2pm lecture. Many were saying the paper was hard but I thought it was definitely easier than Physics 1. I think I got 72% or so last semester (approx 60% on the exam). Did way better this exam
