Problem 1 The forward and inverse distances of a line in an X Y system: a. b. c. Are different Are the same Depends on the azimuth Problem 2 Total station distances are based on: a. Speed oflight b. Time of electromagnetic propagation c. Multiple wave lengths plus phase shift Problem 3 Legally, surveyors must report distances that are: a. Horizontal b. Vertical c. On a slope, as measured Problem 4 The sag correction for tapes is always: a. Positive b. Negative c. Can be either

Solution

1) Option B is correct. In a line forward and backward distances are same.

2)Option B is correct. it depends on the electro magnetic propagation.

3)Option A is correct. The distances that are measured in surveying are horizontal distances. So, he has to submit horizontal distances.

4)Option B is correct. It is always negatives.
