I did so bad in this paper T_T. I didn't even have time to recheck my answers and at end of exams I noticed I forgot to convert 450g to kilograms for the Kinetic change in energy( the slope diagram question)

And the waves A, B explanation the questions were like chinese to me, had it ask in a more direct way I would have understood it was asking for where the nodes and antinodes were situated

And that final question, I completely forgot to consider mass of atoms ;_;

I think it was 2.2** I got 22** (forgot the 2 numbers after) Because I forgot to divide by 1000
And thank you for telling me about the mass, yeah coincidentally a friend of mine just told me the same thing before I went for mechanics paper lol
The mass actually is so small that you consider the mass of both atoms to be similar( so using only 1/r^3 is right)

Though I used, 1/4/3Pi(d/2)^3 :p
No Problem. How was mechanics? :)
