Barometric levelling is based on the principle that atmospheric pressure:
सही उत्तर: ग) Decreases with increase in altitude
Since air pressure decreases with height, measuring pressure differences gives approximate elevation differences.

A levelling staff that is telescopic, with sections sliding into each other, is commonly known as:
सही उत्तर: ख) Sopwith staff
The Sopwith (telescopic) staff extends to about 4 m in sliding sections.

In the whole circle bearing (WCB) system, bearings are measured:
सही उत्तर: ग) Clockwise from north, from 0° to 360°
WCB is measured clockwise from the north end of the meridian, ranging from 0° to 360°.

In an automatic (auto) level, the line of sight is kept horizontal by:
सही उत्तर: ख) An internal compensator
An optical-mechanical compensator automatically maintains a horizontal line of sight once the instrument is roughly levelled.

-
The vertical angle that a freely suspended magnetic needle makes with the horizontal is called:
सही उत्तर: घ) Dip
Dip is the inclination of the magnetic needle to the horizontal, zero at the magnetic equator and 90° at the magnetic poles.

-
The horizontal angle between the true meridian and the magnetic meridian at a place is called:
सही उत्तर: क) Magnetic declination
Magnetic declination is the angle between true north and magnetic north at a place.

-
The horizontal angle a line makes with the true (geographic) meridian is called its:
सही उत्तर: ख) True bearing
Bearing measured from the true meridian (through the geographic poles) is the true bearing.

-
The two-peg test on a level is carried out to:
सही उत्तर: घ) Check whether the line of collimation is parallel to the bubble axis
The two-peg test is a permanent adjustment check for collimation error, i.e., whether the line of sight is horizontal when the bubble is central.

A plan drawn to a scale of 1 cm = 20 m is shrunk so that a line originally 10 cm long now measures 9.8 cm. The shrinkage factor is:
सही उत्तर: ख) 0.98
Shrinkage factor = shrunk length / original length = 9.8/10 = 0.98.

A map has an RF of 1/25,000. A distance of 8 cm on the map represents a ground distance of:
सही उत्तर: ग) 2 km
Ground distance = 8 × 25,000 cm = 2,00,000 cm = 2 km.
