Guys can someone help me please. My AS practical exam is in 2 days and the teacher told us that 90% chance that electricty (judging by previous papers) is not coming which leaves only mechanical physics (don't scream and shout if electricty comes) . So i have a few questions
1) when attaching springs in series do you measure the extension of 1 spring or all of them?
2) when attching springs in parallel do you take the average extension of the springs because they all don't extend by same amount exactly
Thanks
