What scientific figures are digits read directly from the measuring instrument plus one more digit which is blank by the observer?
The digits read directly from the measuring instrument, plus one additional estimated digit by the observer, represent the concept of significant figures in scientific measurements. The significant figures include all known digits plus one uncertain digit, which reflects the precision of the measurement. This practice ensures that the precision of the measurement is communicated, allowing for appropriate calculations and comparisons in scientific work.

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 point from where an azimuth originates on a map?
An azimuth originates from a reference point, typically known as the observer's location or a specific point of interest on a map. This point serves as the starting reference for measuring the angle, which is expressed in degrees, in a clockwise direction from true north. The azimuth helps in navigation and orientation by indicating the direction to a particular destination relative to the observer's position.
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 many zeniths are there?
In a general sense, there is one zenith for each observer at a specific location on Earth, defined as the point in the sky directly above them. However, if you consider multiple observers in different locations, there can be countless zeniths, as each person's zenith corresponds to their unique position on the planet. Thus, the number of zeniths is effectively infinite when accounting for all possible observer locations.
Is this statement true or false the horizon is the point where to an observer the earth and sky appear to meet?
True. The horizon is the line where the Earth's surface and the sky seem to meet from the perspective of an observer. It is influenced by the observer's height and the curvature of the Earth.
Significant figures are digits read directly from the measuring instrument plus one more digit which is by the observer?
Estimated
Significant figures are digits read directly from the measuring instrument plus one more digit which is what by the observer?
estimated
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.
What term refers to the point in the sky which appears directly above the observer?
Zenith
Point directly overhead?
The point directly overhead an observer is called the zenith. It is located at a 90-degree angle from the observer's position, directly in line with their vertical axis. Astronomically, the zenith is used as a reference point for celestial coordinates and observing objects in the sky.
What is the role of an objective observer in evaluating the validity of scientific experiments?
The role of an objective observer in evaluating the validity of scientific experiments is to assess the methods, data, and conclusions of the study without bias or preconceived notions. Objective observers help ensure that the experiment was conducted properly and that the results are reliable and can be trusted by the scientific community.
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.
How a sextant work?
i guess planets
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.
