What did everyone tick for the battery question. I ticked the 1st one, no idea if it was right.
3rd one

You're meant to plus the voltage in a series circuit so you were meant to tick the third box, 9+3= 12V

The potential difference is shared according to my revision guide

It was the one with positive and negative ends, third box i think

I ticked the 3rd one. It was a pure guess

Was going to tick that aswell :/

I got that but all of my classmates subtracted
7. Was the answer before, as or after?
8. (Original post by Monsor)
The last question was 22 m/s^2

Posted from TSR Mobile
That's what I got the first time round but it explicitly said that it was the "upwards force" and not the resultant force...on the equation sheet it's F=ma where F is the resultant force, I doubted that they intended the "upwards force" and the "resultant force" to be the same thing. In the big scheme of things it seems somewhat insignificant but who knows!

Just a general point: for the battery question with the tick boxes you just needed to make sure that the cells were all facing clockwise (or anticlockwise I can't remember) so that the charges all flow one way.

Erm I know it's shared but you have to add them up m8...
This is the aqa additional science book..

10. Everyone try and remember the questions (what they asked/said) and marks awarded so we can make an unofficial markscheme!

Got 8.7A for one of them
For that last one I got 12m/s^2, fairly sure you had to take into account the 840N weighing the guy down and calculate the overall resultant force
Hard paper though
Yes, I took away 840 from the bigger number because you needed the resultant force in the equation. Paper was fairly hard.

1a) what was the main error with the oil experiment (1mark)
13. Was 84kg correct for one of them? Jet pack question I think
Was 84kg correct for one of them? Jet pack question I think
i got that

Yeah I got that to
16. The graph with the 2 curved lines was stressing me out i almost ran out of time because i was staring at it for ages

That graph absolutely mind ****ed me
18. Did anyone get 52 N for the boy doing pull-ups question?
19. I got the 8.7A
20. 52 Newton. I'm deffo wrong thou
