← HistoryWhich outcome occurs when an astrolabe's alidade rotates excessively during observation?
A)Parallax error reduces angular accuracy✓
B)Corrosion accelerates on brass components
C)Index slippage alters degree measurements
D)Gear meshing suffers increased wear
💡 Explanation
Parallax error causes reduced angular accuracy because incorrect alignment with the target increases with rotation; the observer's line of sight deviates from correct celestial position, therefore angular measurements are inaccurate; rather than mechanical failures.
