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 θ = (z + δ) - 180° θ = 180° - (z + δ) θ = δ - z θ = z + δ θ = (z + δ) - 180° θ = 180° - (z + δ) ANSWER DOWNLOAD EXAMIANS APP
Surveying For any star to be a circumpolar star, its Declination must be 0° Distance from the pole must be less than the latitude of the observer Hour angle must be 180° Declination must be 90° Declination must be 0° Distance from the pole must be less than the latitude of the observer Hour angle must be 180° Declination must be 90° ANSWER DOWNLOAD EXAMIANS APP
Surveying The rate of change of parallax dp/dh with respect to change in h, may be expressed as fB/(H + h) fB/(H + h)² fB/(H - h) fB/(H - h)² fB/(H + h) fB/(H + h)² fB/(H - h) fB/(H - h)² ANSWER DOWNLOAD EXAMIANS APP
Surveying Which of the following errors can be neutralised by setting the level midway between the two stations ? error due to refraction only None of these error due to curvature only error due to both curvature and re-fraction error due to refraction only None of these error due to curvature only error due to both curvature and re-fraction ANSWER DOWNLOAD EXAMIANS APP
Surveying The latitude (λ) of a place and the altitude (α) of the pole are related by λ = α - 90° λ = 180° - α λ = 90° - α λ = α λ = α - 90° λ = 180° - α λ = 90° - α λ = α ANSWER DOWNLOAD EXAMIANS APP
Surveying The error due to eccentricity of inner and outer axes can be eliminated by double sighting taking mean of several readings distributed over different portions of the graduated circle reading both verniers and taking the mean of the two taking both face observations and taking the mean of the two double sighting taking mean of several readings distributed over different portions of the graduated circle reading both verniers and taking the mean of the two taking both face observations and taking the mean of the two ANSWER DOWNLOAD EXAMIANS APP
