0 1 . 2 A metal wire of diameter d box is held in the gap between the anvil and the spindle. Just before the reading of d is taken, the gap is closed using the ratchet and not the thimble. Explain why the gap is closed in this way. [1 mark] 0 1 . 3 The mass per unit length μ of the metal wire is given by 2 4 μ = πρd where ρ is the density of the metal. Values of d and μ are used to calculate ρ. The percentage uncertainty in d is 1.2%. The percentage uncertainty in μ is...
