Surveying When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is θ = δ - z θ = (z + δ) - 180° θ = z + δ θ = 180° - (z + δ) θ = δ - z θ = (z + δ) - 180° θ = z + δ θ = 180° - (z + δ) ANSWER DOWNLOAD EXAMIANS APP
Surveying The meridian of a place is A great circle passing through the place and the poles A great circle whose plane is perpendicular to the axis of rotation and it also passes through the place A semi-circle which passes through the place and is terminated at the poles An arc of the great circle which passes through the place and is perpendicular to the equator A great circle passing through the place and the poles A great circle whose plane is perpendicular to the axis of rotation and it also passes through the place A semi-circle which passes through the place and is terminated at the poles An arc of the great circle which passes through the place and is perpendicular to the equator ANSWER DOWNLOAD EXAMIANS APP
Surveying If θ and δ be the latitude of an observer and declination of a heavenly body respectively, the upper culmination of the body will be south of zenith if its zenith distance, is θ + δ δ - θ ½ (θ - δ) θ - δ θ + δ δ - θ ½ (θ - δ) θ - δ ANSWER DOWNLOAD EXAMIANS APP
