That was terrible, was hoping for at least a B but think thats gone!

what did you draw for the intensity graph for the red laser?

Did anyone else get 42J for the counting squares one?

I thought it was a really nice paper apart from the 6 marker, couldn't have asked for a worse 6 marker!

Hopefully I got around 108UMS

agree! hopefully most people found it and then the grade boundaries will be lower. All the other papers i did i managed to get an A or B but this was awful

just higher intensity- so higher curve thingy

Grade boundary predictions?

drew it lower to the orginal graph but the same pattern...not sure if im right though

Indeed, it counted each square as 1 rather than whatever it was for each square :frown:

stupid mistake, thanks anyway

And wider!

I dont think it would be more intense, certainly wider but not sure about the more intense.

Text book says wider, nothing on intensity but it may have just missed it out

How did you draw the velocity time graphs?

Didn't think it was too bad tbh, I know I got the work done wrong by a factor of ten (10.4 or something) but other than that okay :smile:

I went higher and wider for the red laser :smile:

I still can't believe the 6 marker lol.... it was such a bad one. I could only think of about 4 points to write.

Did anyone get the weight of the ball to be 0.44N (or thereabouts). I was confused by this question at first until I saw the formula for the volume of a sphere.

Overall I thought it was a harder than average paper, so the grade boundaries will be lower-normal.
