← HistoryWhich outcome arises when a mariner attempts to determine latitude using a Kamal in conditions of high humidity?
A)Inaccurate angle measurements result✓
B)Stars appear brighter erroneously
C)Alidade armatures fracture rapidly
D)Parallax error becomes insignificant
💡 Explanation
High humidity causes the cords supporting the Kamal's knot to stretch due to hygroscopic expansion, altering the graduation interval. This causes errors in angular measurement due to linear interpolation gone-wrong because the length is no longer reliably correlated to angle, therefore accurate latitude estimation is lost on celestial bodies, rather than any changes in observation or parallax.
