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?
