सही: ० / ०
-
The UTM grid system is normally used between the latitudes of:
सही उत्तर: घ) 80° S and 84° N
Beyond about 84° N and 80° S, the Universal Polar Stereographic (UPS) system is used.

In the UTM system, the central meridian of each zone is given a 'false easting' of:
सही उत्तर: ग) 500,000 m
A false easting of 500,000 m ensures all eastings within the 6° zone are positive.

A map scale of 1 inch to 1 mile expressed as a representative fraction is:
सही उत्तर: ख) 1 : 63,360
1 mile = 5280 ft × 12 = 63,360 inches, so RF = 1 : 63,360.

-
The 'deflection of the vertical' at a point is the angle between:
सही उत्तर: क) The direction of the plumb line (gravity) and the normal to the reference ellipsoid
It arises because the geoid and ellipsoid are not parallel, and it links astronomical and geodetic coordinates.

-
A theodolite is set up 100 m (horizontal distance) from a staff station, and the vertical angle to the target is +5°. Neglecting instrument and target heights, the difference in elevation is about:
सही उत्तर: घ) 8.75 m
Difference in elevation = D tan α = 100 × tan 5° ≈ 8.75 m.

-
A gyro-theodolite is especially useful in tunnel and mine surveying because it can:
सही उत्तर: ग) Determine true (astronomic) north underground, independently of surface connections
The gyroscope seeks the meridian under the earth's rotation, giving azimuth where stars and GNSS are unavailable.

-
The positions of bridge piers in a wide river, where direct taping is impossible, are commonly fixed by:
सही उत्तर: ख) Angular intersection from the ends of a measured base line on the bank
Theodolites at the ends of a shore base line set out computed angles; the piers lie where the lines of sight intersect.

-
A surface float travels 50 m along a straight reach of a river in 40 seconds. The surface velocity is:
सही उत्तर: क) 1.25 m/s
Velocity = distance ÷ time = 50 ÷ 40 = 1.25 m/s.

-
The 'upper culmination' (transit) of a star occurs when it:
सही उत्तर: घ) Crosses the observer's meridian at its maximum altitude
A star culminates twice daily on the meridian; at upper culmination it reaches its highest altitude.

-
The equinoxes are the two points (or instants) at which the sun:
सही उत्तर: ग) Crosses the celestial equator
At the equinoxes the sun's declination is zero, as it crosses the celestial equator, and day and night are nearly equal.
