The question which asked What is wrong with the circuit?

I put-

1- The voltmeter & ammeter need to change places.

2- switch needs to be closed.

How many marks will I get?

You might get zero if the marking is harsh because the switch not being closed is the same as a light switch not being on its designed to be like that and the ammeter and voltmeter probably have to be described using scientific vocab eg. ammeter is connected in parallel and voltmeter connected in series and it needs to be the opposite way round.I put the ammeter and voltmeter as the 2 answers.

I don't think so, because nuclear radiation isn't man-made, its what the whole thing is called.

I think coulombs will be fine because i remember doing past paper and they are like accept 'coulombs' or a capital 'C'.

Do you think I will get 4 or 5 marks for this six mark question?:

Once it reaches at the end of the main sequence it expands into a red super giant. Then it collapses on its own gravity and explodes into a supernova. If the mass of the supernova is high enough, it will turn into a neutron star. If the mass is massive, it will turn into a black hole instead. In the black hole, light can't escape from it since it is so powerful that it is faster than the speed of light.

I have just had a thought if people missed the 2 hours thing and then calculated the first part wrong and then did the second part would they get the full follow on marks of only 1 mark/2 because the answer is still incorrect.I hoping its they don't so the grade boundaries go down.

Is a nuclear reactor accepted for the man-made question?, also would just 'speed' on it's own be ok for the question which asked what affects braking distance other than poor brakes?

You would probably get both marks I think not fully sure on the first one but I think the question said name a man-made source of background radiation and nuclear reactor fits into that, in my opinion.
