Plumb bob lines at two different places in geodetic surveying will _____.

Calculate the true reduced level (m) of a point A after correcting the refraction and curvature. The staff reading at the point taken from an instrument set at a distance of 2 km from the point A is 2.56 m. The staff reading from the same station on a bench mark of reduced level is 100 m is 1.34 m.

Which one is the CORRECT expression for the horizontal distance between the instrument and the staff for the anallactic telescope, if S is the staff intercept, K and C are multiplying and additive constant?

With an increase in the denominator of the representative fraction, the scale of the map will _____.

Calculate the length of one division of the vernier scale, if least count of the combination of main and vernier scale is 0.02 mm. The least count of the main scale is 1 mm.

Which one is the CORRECT statement?

Which of the following statement is CORRECT for whole circle bearing?

Calculate the length (m) tangent of a 5 degree curve, if the deflection angle is 60 degree.

Calculate the limiting length (m) of the offset, if the maximum allowable error in laying offset is 2 degree. The scale of the map is 1 cm = 100 m.

Calculate the error in the staff reading on a staff at a distance of 100 m due to out of the center of the bubble by 4 divisions. The sensitivity of the bubble tube is 30 seconds per 2 mm divisions.
