Question

With a caliper (Δr=0.05 mm), the edge L of a pure copper plate is measured only once. The value read by the experimenter is L=10.00 mm. It is known that the density of copper is ρ=(8.8900±0.0058)×10³kg/m³. What is the mass of the cube with its uncertainty?

a) m ± um = (8.890 ± 0.078) g

b) m ± um = (8.890 ± 0.078) kg

c) m ± um = (8.890 ± 0.078)×10-3 g

d) m ± um = (8.90 ± 0.078) g

e) m ± um = (8.90 ± 0.08) g
