Anyone want to discuss any q’s that would be lovely. If anyone has found the answers that would be great.

2

I thought it was pretty hard to be honest. I’m hoping for a 75+. Did you get 360 ohms for that one question with parallel circuit? Also, did you get 76s for one of the early part 2 questions?

3

Here are a couple more that I remember off the top of my head:

Towards the end, I think questions 80 something, I put that power would stay the same and for the question after that, I put that equivalent resistance increased.

55-56, I did not get at all… I think it asked about finding the mass of a proton in terms of joules or something.

for the accel. question, in part 2, I got 2.88 m/s^2

4

I thought it was pretty hard. Was the refracted angle 60 degrees?

5

56

6

I thought that it was a fair test.

7

I thought it was difficult and tricky… especially the one were you had to convert from grams to kilograms (almost messed up on that one)

8

I came out thinking it was fine but now I’m starting to question everything.

9

Does anyone remember if weight and force of friction was supposed to be negative for that one short answer question?

10

I shoot I forgot abt that. I hope not

11

*oh

12

Yes I got 360 ohms but the time one I got 22sec but i think I got wrong. Your prob right

13

And yeah 2.88 I got and the eq resistance was higher in series than in parallel because its R2+R2 etc

14

R1 + R2 meant to say

15

Right. All I can remember sorry. I don’t know how I did on the multiple choice… either really well or really bad. Only time will tell I guess. You remember any more answers/questions?

16

for the question regarding the energy of the proton, all you had to was use e=mc^2. m= rest mass of proton (on ref table) and c= speed of light (again on ref).

17

Does anyone remember the short answer question where they asked you to find the time and they give you the components?

18

The one with the football?

19

yeah! How long was the ball in the air or something like that?

20

I, and two people I asked, got 1.52 seconds for the football question.
Just plug the numbers into the vf=vi+at formula and multiply the time by 2
