answ 2. Due to the travel of the earth around its (non-circular) path on the ecliptic; and the tilt of the Earth's axis, the path of the (say) tip of the flagpole will not repeat exactly until a year has passed.

The path of the shadow of this 'flagpole gnomon' will describe a passage known as the Equation of Time.

This you can look up in an encyclopedia or a search engine.

what causes shadow length?

The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
