1. Couldn't find a thread so decided to make one,,,

how did u guys do??
2. Generally a decent paper though I messed up in a 3 mark question. hoping for 60/80 and abov... What happens if you didn't find the angle between the B-field and the conductor and you used F=BIL direct? would I lose all marks?

Yes, unfortunately, you will get 1/3 for that question maximum
Do you remember all the questions, because I have already forgot them a little ?
4. What was the angle guys? I found 17° and multiplied it with cos17

Do not remember the final answer< but the one I MEASURED was something like 58

Me too, i couldn't find an angle :'(

What was your answer in the last question to the part that said ( what other measurement she should have in order to find the speed of the balls?)

Not sure the we were asked about additional measurements. I wrote that the collision is inelastic and explained why

Aaaah, sorry, got you now I said the time between two nearest photos, so that speed could be calculated.

9. For the diagram about the Baryon-Meson, I used a pencil to fill the circles with the quark composition, does it really matter if it was in pencil or pen? since it was a DIAGRAM, that's why I used a pencil

You used a protractor I suppose? I also got 17 degrees but I used sin17 since we required the vertical component not the horizontal

Yes i used a protractor. It was a magnetic field so i thought the horizontal component must be at right angle to the field
