Could I see your calculations
and I only see a single question in which you put 2s, where did the other answers come from?

Yeah just use the formula to work out length
then re-sub this value into the formula again but change g=3.71

Yeah just use the formula to work out length
then re-sub this value into the formula again but change g=3.71
so is it L= gx (2/2pi)^2
so its 9.81x(2/2pi)^2 = 0.993
then i did 2pisqrt (0.993/3.71)= 3.25?
is that the answer am i doing it right correct me if this is right?
