An astronomical sextant has main scale divisions of 20 minutes. If the desired least count for an extended vernier is 10 seconds, design the extended vernier.
In the prismatic compass, the graduations start from zero, marked at the _______ end of the needle and run______
A tachometer is set up at point A, and the staff readings at point B are 1.77 m, 2.12 m, and 2.34 m. The inclination of the line of sight is 1 degree 9 minutes (1°9').
Calculate the vertical distance between points A and B. Take k = 100 and C = 0.3.
The local means time at a place located in longitude 90 ° 40' E when the standard time is 6 hours and 30 minutes and the standard meridian is 82 ° 30' E is
In the leveling between two points A and B on the opposite sides of a pond, the level is first set up near the point A and staff reading on A and B are2.5 m and 2.0 m respectively. Then the level is moved and set near the point B, staff reading on points A and B are 1.2 m and 1.7 m respectively. Calculate the difference of heights between the two points A and B (in metre).
