When manufacturing precision-engineered components for a spacecraft, the length of a critical component needs to be determined with extreme accuracy. If this component should have a length of 30 cm to within ±0.1 mm, what percentage of uncertainty in the length is permissible, and how many significant figures should be used in the measurement of the length?
