OMG THAT EXAM PAPER WAS WEIRD.
Seriously... some of the questions I didnt know what to calculate!
Did anyone do the rubber extension question that was 6 marks?
I put the stand clamp and attatched the rubber, measure it, add known mass, measure length of rubber again, calculate delta L and find K using the equation F=KdeltaL.
Do repeats to increase accuracy and plot a graph of force against extention.
...please someone telll me Iam right... T__T I swear I am gonna cry if thats wrong.
