I thought this exam wasn't half bad tbh.
I left a couple answers blank I must admit. The Keplar's Law question, and the damping question!
A couple dodgy mistakes and answers I made/gave were...
Forgot that a W was a Js, so just used E=12, instead of E=12x60x60...would using E=12 only drop one of the marks, I did all the other conversions correctly???
For the escape velocity I simply wrote that Helium is lighter than air, so floats up!! Any chance whatsoever for a mark?
I think that's about it, undoubtedly there will be other errors in there!
Hoping for at least a B, but we shall see!
