    As it usually goes let's see if we can regurgitate the questions and get someone who can actually do the subject to answer them properly for us.

    1) To win a 400m race, the runner needs:
    - biggest initial velocity?
    - biggest acceleration?
    - biggest average velocity?
    - ??

    unknown) Discuss why Graphene might not be suitable for all applications in spite of its high breaking stress (compared to Steel)

    unknown) I got Cornstarch for the viscosity

    1) highest average velocity

    unknown 1) it has high strength only along a single axis. Also it's material properties for thermal and electrical conduction are completely different. There are so so so many reasons. Not sure what they'd want for A-level tbh...

    unknown 2) what's the question?
