Why does the mark scheme show the current to 3 sf? Would i lose marks if i gave the answer to 2 sf since the least amount of sf given in the question is 2sf.
Its January 2013, but then you're giving a more accurate measurement than the actual question are you not?
Yeah that's what I'm thinking - guessing that's why it says 2 or more. However the actual answer is to 3 as is with the other questions so I'm assuming they want 3. That's what I usually do anyway
