Midterm thoughts

What did everyone think of the midterm?

I thought it was much more manageable than the first one.

piece of cake

little tricky but wayyyy better than the first...i think this time all the answers were B instead of A on form 0...lol

well...personally the thing i always thing about physics exams is that there's never enough time to finish every question...overall i thought it was more manageable than the first exam; however, i could've used some more time.lol

Only 4 answers were 'B'.

I think average will be very high this time...good or bad?

i thought the test was ok but then i looked at the answer key and was stunned.
lots of room for silly mistakes and some really tricky questions.

Yea it was a bit tricky..I got a mediocre 85. and I still don't know how to calculate that error problem. ANY IDEAS???

Basically, F= 1/(2Pi*sqrt(L*C) or F= 1/(2Pi*(L*C)^1/2. When calculating the relative error Delta F/F, you isolate all the constant values of the formula and set that as C to get F= C * (L*C)^ 1/2 so in this case C= 1/2pi

From there you must follow the relative error formula that delta F/F= n* (relative error of LC). To calculate the relative error of LC you do
sqrt((deltaL/L)^2+(deltaC/C)^2) and then you multiply whatever you get there by n, the exponent in this case 1/2 to get a 3.54% relative error.

Brian, I know in your world saying "I got a mediocre 85" seems like a normal thing to say, but it implies that anyone who did not get at least an 85 is less than mediocre. If you're trying to show off, remember these 4 things:

1. Plenty of people did better than you (me).
2. Nobody likes people who try to show off.
3. You might have done well on this test, but you suck at life.
4. Nobody cares.

Maybe Brian wasnt trying to show up and actually thought an 85 was mediocre considering that the test was really is. He probably thought an 85 amounted to at best 10 points above the average.

show off* I meant
and test was really 'easy' not is LOL

Hey I feel stupid for asking this but can someone explain how to read those histograms? I know how to read the bell curves but I'm not sure how to read the ones put up in this course. Thanks in advance.

Hey Brian I'm sorry about what I had said earlier. I was all caught up in the moment and had to resort to hateful and incendiary coments. This stems from my lack of self esteem because I was abused as a child I am i am horrendously ugly. Please forgive my harsh words. I really didn't get higher than you but I will try next time. Peace dude.
