What else can I help you with?
Significant figures are digits read directly from the measuring instrument plus one more digit which is what by the observer?
estimated
Is 55 degrees above the horizon very low in the sky - ie very close to the horizon?
If the horizon is on a level line of sight, a vertical line directly above the observer forms an angle of 90 degrees. 55 degrees would be quite high, being above 45 degrees.
Is ten minutes long?
According to Einstein's famous Theory of Relativity, the answer depends on the observer's frame of reference, and it can be different for different observers. If the observer is sitting on a hot soldering iron or standing on a campfire, then ten minutes appears to be many years long. If the observer's girl friend is sitting on his lap, then ten minutes appears to be shorter than the bit time on a multi- gigabit fiber trunk. Everything is relative to the individual observer. It could be stimated by an activity. for instance, If you want to hold your breath for ten minutes is long but if you are having fun doing something, ten minutes is a very short time.
An observer who is 6 ft tall has an angle of elevation of 60 to the top of a tree and is standing 20 ft from its base How tall is the tree?
ABOUT 2O FEET
Why does Emc squared?
Because the speed of light is the same for every observer, no matter how fast or in what direction he may be moving. Everything else in between is just algebra.

The point directly overhead of an observer is said to be his?

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.
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.
What is the imagenary point in the sky directly above an observer on Earth?
That's the observer's 'zenith'. Since it's referenced to the "observer's head", each observer has a different zenith.
What is an imaginary point in the sky directly above the observers head?
The zenith.
