OT OF 6. Field notes should be discarded when a project is complete. OT OF 7. Sketches in a field book should be drawn to an accurate scale. OT OF 8. A zenith angle is measured in the horizontal plane. OT OF 9. The sensitivity of a level vial is determined by its radius of curvature. OT OF 10. In leveling, balancing plus sight and minus sight distances corrects for instrument collimation errors. uaus causes the line of sight to appear to be too high.

Solution

6. FALSE - They shall be kapt as future record

7.FALSE - need not to be drawn to accurate scale as it will consume more time to survey.

8. FALSE - zenith angles are measured in vertical plane

9. TRUE -  The sensitivity is determined by the radius of curvature of the vials which the bubble moves across.

10. TRUE
