Light leaves the lamp and travels in straight lines from its point source. As you move away from the source, the angle between you and the light changes and this the length and position of your shadow changes.

What is the surface development in term of drawing and define what is the true length in the surface development?
th surface development is the flat, 2D shape that has to be cut in order to make a 3D form when folded and assembled together. true length is the actual or real lenght of any edges ordistane across a face . it is imperative to know or determine the true length in order to obtain an accurate form after mounting or joining of the flat surface develoopment.length distortion occurs according to position of viewer;for an inclinedsurface, the actual or true length appears reduced th surface development is the flat, 2D shape that has to be cut in order to make a 3D form when folded and assembled together. true length is the actual or real lenght of any edges ordistane across a face . it is imperative to know or determine the true length in order to obtain an accurate form after mounting or joining of the flat surface develoopment.length distortion occurs according to position of viewer;for an inclinedsurface, the actual or true length appears reduced
What is the unite for gradient in a topographic map?
"Gradient" of a point quantity is a measurement of how fast it changes in a specific direction. For topography, the gradient of the land is its slope in some direction. It would work out to be dimensionless, because it has to be change in elevation/distance which is length/length no matter what units you use for the elevation or distance.

How has the world's orbit changed since the 8.9 magnitude earthquake and the tsunamis?

If the lamppost is not the light source then lampost's shadow is 112/(64/20) ie 35 inches.
How does the position of the sun in the sky relate to the length of the shadow cast by an object?
The position of the sun relates to the length of the shadow cast by an object because, when the sun is above the object there is no shadow yet, when the sun is say to the east of the object a shadow is cast towards the west, the farther the sun for example east the longer the shadow will be towards the west.
How would the change in the suns path from summer to winter affect the length and position of shadows?
Exactly the same as the change in the sun's position from noon to sunset affects them ... they stay exactly opposite the direction of the sun, but they get longer.

A person of height 1point72 m is walking away from a lamppost at 1 m per s the light on the lamppost is 5 point 8 m above the ground at what rate is the length of the persons shadow changing?
That rate changes as the person's distance from the lamp-post changes. If you specify how far away he is from the lamp-post at some instant in time, we can calculate how fast the length of his shadow is changing at that same instant. This is a perfect example of a simple differential calculus problem.
