# AQA Physics GCSE P2 & P3 [OFFICIAL THREAD] watch

1. (Original post by Bobby21231)
Did anyone else get 51 coulombs for charge question
Yeah
2. I got 510 for that question
3. (Original post by Niamhiscool)
I got 360J )
You had to use the equation E = P x t, but the power was not given, only the voltage was given. Therefore to get the power, you had to do 12V multiplied by 1.7A to get 20.4A. Then do 20.4A multiplied by 30 seconds to get 612J? Surely.
4. I thought the paper was alright apart from a few stupid 1 mark questions. Predicted grade boundaries?

Or use the charge from the previous question? No need to bother finding out power

I just did 51 coulombs multiplied by 12 volts to get the energy and the answer was still 612 joules

I think thats what I did lmao idk at this point can't change it anyway
8. (Original post by maxjackson5)
Yeah I did use the charge from the last question, it was 1.7A.
But that's current not charge
10. (Original post by Bobby21231)
But that's current not charge
Yeah sorry just realised that ahaha, still should get 2 marks though
11. For the half life question I got 9😭😭

The roots of education are bitter, however the fruit is sweet.

What?
13. I really can't see how the grade boundary for an A* could be anything less than 48 to be honest.

Yeah sorry just realised that ahaha, still should get 2 marks though
But if you still got 612 joules you will get 3 marks as you just did it another way
15. What was the coulombs question again?
16. Did anyone get 12 for the half life question? I see people saying they got 9, some saying 12. Which is right?????
17. What did everyone put for the bus toppling question about the angle being greater I can't remember the actual question but it was a suggest two reasons one?

18. Was the first question... It was directly proportional and then I chose C for the next...?

I got 22.5

I'd be lucky to get 3 marks on a 2 mark question ahaha xD
