Probably not, the SQA sorts the papers I think before they are sent out to markers (by Royal Mail I heard, so there's a chance of bags of scripts lying on a marker's front door unattended). And in any case, the marker could just pocket the £20 and still mark you wrong, there's no way you can force him to uphold his end of the bargain.
For the one about a point source, did anyone write that it wasn't a point source due to the irradiance decreasing as the distance increased
I remember doing a wee bit of private research on Lasers (being a point source) and I read that the intensity increased with distance , wasnt sure if this was valid or not .
Irradiance does decrease with distance, and that happens wether it's a point source or not, but the way to prove this wasn't one was that I*d^2 was not a constant for the three values

Scholar: "An ideal point source is one which is infinitesimally small and radiates with equal irradiance in all directions." Seems to rule out lasers from being a point source
In fact I remember reading somewhere that lasers are indeed not point sources and their irradiance remains constant at short distances.

Woops I am a total Div I wish I looked over that section, well more than just reading over it once
