S1 (Viva Voice) Part A Question 1

S1 (Viva Voce) Part B Reflection:
 The challenges were that i had almost no time to prepare so  i was saying what ever came into my mind 
that made me stop and pause for a while and think back on what to do 
What i should have done is to should have made a script to guide myself in the explainnation

  1. Part (i): You have pointed out that both lengths are equal, so can formulate the equation. You have also attempted to explain the solving of equation using the 'balancing act'. Excellent!

    For (ii): The substitution was systematically explained.

    For (iii): The explanation on the unit conversion was very well explained. However, did you check you final answer? It should be 0.023 m^2.
