1. The orientation of the table is done by

2. The RL of the benchmark is 1000.0 m, and the back sight reading at the benchmark is 2.555 m. Find the staff reading of IS if the RL of IS is 1000.055 m

3. The types of survey used to fix property lines are

4. The advantage of anallatic lens is

5. The process of bringing the vertical circle to the right of the observer is called

6. "A curve of varying radius introduced between two branches of a compound curve is called

7. In a closed traverse by included angles, the sum of measured interior angles should be equal to

8. A chain 33 feet long and consisting of 16 links each 2(1/16) feet long is

9. Azimuth and altitude of a star

10. "Cross-sectioning" and "Longitudinal sectioning" is

11. If the staff is held vertical and the angle of elevation and depression are kept the same, then the horizontal distance between the instrument and staff station computed by observation will be

12. It is more difficult to obtain good results while measuring the horizontal distance by the stepping method

13. The three-point problem is concerned with:

14. For a tacheometer, the additive and multiplying constants are respectively

15. Short offsets are measured with

16. Bowditch's rule is applied to

17. A building is an obstacle to

18. The surface perpendicular to the direction of gravity is

19. Direction of the closing error is given by

20. In trigonometrical leveling, the combined correction is given by (where m=coefficient of refraction)

21. Right face and left face readings are taken to

22. The included angles of the theodolite traverse are generally measured

23. A 30 m long tape was standardized at a temperature of 30°C; at the time of measurement, the temperature recorded was 35°C. Then the correction for temperature per tape length is (coefficient of thermal expansion = 0.0001116/°C)

24. If the temperature increases, the sensitivity of a bubble tube

25. In a closed traverse, the closing error should not be more than (where N is the no. of sides of the traverse)

26. The bearing of line AB is 200° and that of BC is 270°, the included angle ABC is

27. Negative errors are caused in the chain when its length is

28. A 30m chain was found to be 20cm too long after chaining 1500m. The correct length of the total distance chained will be

29. Secular variation is an important factor because

30. The chord of curve less than peg interval is known as
