The solar elevation angle at the Arctic Circle on September 21 at noon would be 0 degrees. This is because the Arctic Circle experiences the autumnal equinox on September 21, when the sun is directly above the equator and does not rise above the horizon at the Arctic Circle.

Which two lines of latitude show the edge of an area where at least one night in the summer the sun never sets and one day in the winter the sun never rises?
The Arctic Circle (66.5 degrees North) marks the latitude where the sun doesn't set at least once in summer. The Antarctic Circle (66.5 degrees South) indicates the latitude where the sun doesn't rise at least once in winter.
How do you find the angle of elevation from the tip of the shadow of a 12 foot flag pole to the top of the pole is 60 degrees?
You can use trigonometry to find the angle of elevation. Let x be the distance from the tip of the shadow to the base of the pole and the height of the pole be y. Then, tan(60 degrees) = y/x. Given that the height of the pole is 12 feet, you can solve for x to find the angle of elevation.
What is the dofference between azimuth and elevation?
Elevation is a vertical lift and azimuth is a rotation around a vertical axis. An example of its use is in radar. The radar antenna rotates towards its target, its azimuth, and then lifts vertically to elevate the receiver then locks on to the target.
Do lines of latitude have names?
Lines of latitude do not have names within the conventional system of measuring latitude using degrees. Lines of latitude are commonly referred to by the numerical value of their angle from the equator, such as the Tropic of Cancer (23.5°N) and the Antarctic Circle (66.5°S), but they are not formally named like lines of longitude.
The angle between the suns position in the sky and the horizon is what?
The angle between the sun's position in the sky and the horizon is called the altitude of the sun. It is the measurement from the horizon to the center of the sun's disk. This angle changes throughout the day as the sun moves across the sky.
What is the difference between angle of Elevation and angle of Depression?
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
Which type of objectives have angle of elevation?
The angle of elevation is looking at an object above your line of sight.
What is a central angle?
Central Angle An angle in a circle with vertex at the circle's center.
What does angle of depression in geometry mean?
It is the alternate angle to the angle of elevation
What is an angle in a circle whose vertex is at the center of the circle?
Central Angle
What the difference between a circle and a angle?
They are quite similar but a angle isbasically part of the circle. if a had an angle of 90 degrees then it is aquarterof the circle. the circle it the whole thing and the angle is part of the thing
Why are sun's rays never vertical towards the arctic circle?
The sun's rays are never vertical towards the Arctic Circle due to the tilt of the Earth's axis, which is approximately 23.5 degrees. This axial tilt causes the sun to follow a lower angle in the sky during the winter months, preventing direct vertical sunlight. As a result, areas within the Arctic Circle experience prolonged periods of low-angle sunlight in winter and continuous daylight in summer, but the sun never reaches a vertical position at noon.
What is the relationship between the angle of elevation and the highest point?
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
At a certain distance the angle of elevation to the top of a building is 60 From 40ft further back the angle of elevation is 45 Find the height of the building?
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
What is an arc central angle and radius of the circle?
Radius: A line from the center of a circle to a point on the circle. Central Angle: The angle subtended at the center of a circle by two given points on the circle.
What is a inscribed angle?
An inscribed angle is an angle with its vertex on a circle and with sides that contain chords of the circle.
What instrument measures angle of elevation and angle of depression?
A sextant.
