tomctutor Thanks so much for this! Just one question though, I got E for 10 (that they were all correct) but in your marking scheme it says the answer to that was D, so III (The mass of a galaxy can be estimated by the orbital speed of the stars within the galaxy) wasn't correct, but on page 40 of the course spec at https://www.sqa.org.uk/files_ccc/Hig...pecPhysics.pdf it says "Knowledge that the mass of a galaxy can be estimated by the orbital speed of stars within it."

I'd appreciate it if you could clarify this. Thanks so much again for this, I really appreciate it!

Sbneelu: Yes thats in the spec I agree, thankyou will ammend my soln.
Its a hard one, I was thinking of Galileo Principle
"the motion of a body due to gravity independent of its mass"
but realized it is dependent on the Mass of the source of the gravitational field!
Thankyou again boobie by me.:ashamed2:

Thanks for uploading this, mildly annoyed that I seem to have gotten 24 wrong, but otherwise happy, wonder if anyone’s got the second paper.

Shouldn’t 1b) have the mass as 57x10-3 for the mass as it’s 57g rather than kg?

For question 2a) would you use w=mgsin0 instead of w=mg or am I just stupid?

For you questions 1-2 of section 2:

For bi) You have said 57kg instead of 0.057kg as the question says 57g. So you answer is off by a factor of 1000 and so is bii.

Thanks for these!

For Q9b, I didn't do anything with a graph but I said you could measure the irradiance with the lamp at different distances to the light sensor and then multiply I by the square of d for each measurement to get Id^2 = k. If k was constant for all the measurements, then Id^2 = k. That can be rearranged to I = k/d^2, which is the inverse square law. How many marks do you think I'd get for that?

You should be able to get full marks (3/3) as long as you talked about the other things in terms of measurements and calculations

My guess is 2 marks. If you look on 2007 higher marking scheme. Then just before the answers show up, there is a whole section on wrong calculations and how much you get for it
