Measure of change in elevation in a certain distance is called what?
The measure of change in elevation in a certain distance is called gradient.
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 a change in elevation?
the measure of change in elevation in a certain distance is called gradient
What is change in elevation called?
the measure of change in elevation in a certain distance is called gradient
A mesure of the change in elevation over a certain distance?
Topography.
A measure of the change in elevation over a certain distance?
This would be the slope or the gradient.
To take a clear picture of an image in a mirror should the camera be focused on the image or the mirror?
An image in a mirror is a "virtual" image which takes on certain characteristics. One of these characteristics is that the apparent distance is equal to the distance from the observer to the mirror plus the distance from the mirror to the subject. If the observer and subject are the same, then the apparent distance is twice that of the subject to the mirror. If the observer is 3 feet from the mirror and the subject is 20 feet away, the apparent distance is 23 feet. If you focus on the subject and have distance markings on your lens, you can prove this to yourself.
What does an elevation map do for you?
an elevation map shows you the different heights of a certain area
What is a measure of the change in elevation over a certain distance?
This is mathematically known as slope or "rise/run".
How do you find length of a tree?
Using trigonometry. By measuring a certain distance from the tree and knowing the angle of elevation you can use the tangent ratio: tan = opp (the height of the tree)/adj (the distance) Rearrange the formula: opp = adj*tan
The change in elevation from one contour line to the next is called what?
The change in the elevation between isolines is called a contour line. Contour lines on a topographical map resemble a volcano.
