Here are my answers, i thought the exam was easier than some of the past papers i did so hopefully i got an A/A*

-For the maximum speed i wrote 17m/s
-The GPE one and KE one i got 7.2
-Momentum was 5 m/s
-The energy transferred was 360j (i think)
-The charge was 51 ohms
-The current was 1.6A at 0.01 seconds

They are the only ones i can remember, what did everyone else get? I think they are right, physics is my strongest subject and i got an A* in the mock
Maximum speed was 22.5 and the energy transfered was 612J

Was the question where you had to draw in refraction only 1 marks? Didnt read it properly oops!
It was to complete a diagram where the angle of incidence is equal to the critical angle. I think you just had to draw a ray along the normal.

No Nuclear Fission doesn't happen in Cornwall ahahahaha
It happens in stars, right?

Hi, I said momentum cant be created or destroyed, would this get the mark?
I think you had to put that the momentum is conserved because it is the same before and after the collision but that may also get you the mark because it's right

Sorry bro but I doubt you could get an A* with those answers. I also put 17m/s but apparently the answer is 22.5m/s. The GPE and KE answers were almost definitely 3.6. Energy transferred was 612J because 12V does not mean power. Charge is no measured in ohms, its measured in coulombs (C). Finally, you had to work out the current at 0.1 seconds not at 0.01 seconds, so the answer was sadly 1.7A not 1.6A.

You could probably get an A though!

The GPE and KE were 3.6J...

I agree, also was the current 1.7A?

The total momentum before the collision is equal to the total momentum after the collision
I thought you might have to mention in a closed system too, so put it to be safe?

I agree.
I Made an educated guess about the current haha and thought X comes before Y so maybe the current flows X to Y! And I got up x

yeah that's what I put
14. i was hoping stars would've come up

I dint think she can put it now the exam is over haha x

GPE and KE is 3.6
Energy transferred was 612 or something like that
The charge is in coulombs not ohms
Apparently max speed is 22.5m/s but I put 17m/s as well.

LOL
17. Has anybody made a full unofficial mark scheme yet??

18. Possible grade boundaries for p2???

I did 50/2 so got 25 m/s for the maximum speed, as that was when I thought gradient was steepest. Is this wrong?

Ahah I was just about to say. All of his were wrong XD Surprised he didn't get put in for the foundation paper
