What is the angle of declination and how do you use it?
An angle of declination is relevant when an observer is at a higher altitude than the object being observed. It is the angle made by the line of sight with the horizontal. Suppose this is angle x. Then if the altitude of the observer is known to be h, then line-of-sight distance to the object is h*sin(x). The object is h*tan(x) from the point below the observer at the level of the object.Conversely, if the line-of-sight distance from the object to the observer or the horizontal distance to the point directly below the observer is known, it is possible to calculate the height of the observer.
What is the Definition of face left and face right surveying?
taking readings using theodolite keeping the vertical circle of the instrument on left side of the observer is called a face left observation and to measure horizontal angle the instrument is rotated(swing) in horizontal plane with respect to the vertical axis in a clockwise direction called rigt swing.
How do you find the angle of depression?
The angle below horizontal that an observer must look to see an object that is lower than the observer. Note: The angle of depression is congruent to the angle of elevation (this assumes the object is close enough to the observer so that the horizontals for the observer and the object are effectively parallel; this would not be the case for an astronaut in orbit around the earth observing an object on the ground).
Is the sun particularly high in the sky at noon if it lies 63 degrees above the observer's horizon?
It is not particularly high but it may be the highest that it can get - depending on the observer's latitude.
What is meant by face left face right in theodolite?
When the vertical circle of the theodolite is to the left of observer, it is in face left position. Similarly when the vertical circle is to the right of observer it is in face right position.
Significant figures are digits read directly from the measuring instrument plus one more digit which is by the observer?

The point directly overhead of an observer is said to be his?
Zenith
What is the point on the celestial sphere directly above observer?
The zenith.
What is a modified Observer's assessment of Alertnesssedation score?
It's a research tool for measuring sedation subjectively.
Which instrument is used in observing distant objects by making them appear close to the observer?
astronomical telescope..
What term refers to the point in the sky which appears directly above the observer?
Zenith
What does the earth have that allows the latitude of an observer on earth's surface to be determined by measuring altitude of Polaris?
Axial tilt.spherical shape
Why is that trait useful in scientific investigation?
There are a great many traits that are useful in scientific investigation. Being an excellent observer is a useful trait for example.
A is the point on the celestial sphere directly above the head of the observe?
That's called the observer's "zenith".
What is periscope means?
a tubular optical instrument containing lenses and mirrors by which an observer obtains an otherwise obstructed field of view.
What is visable on the celestial sphere directly above the observer?
The point just overhead is called the zenith. The objects visible at that point depend on the date, the time of day or night, and the observer's location.
