What should be the height of an electric pole from ground and on factors will it depend?

This depends on voltage and temp rating of the line (at a minimum, there may be other factors such as needing to get over a road, river, etc., topography of the land...). There is a minimum height lines (the actual wire, not the pole necessarily) must maintain - for 12.5kV, they should not dip below 20' (US). They may normally sit at 28', though (as an example) when lightly loaded. If heavily loaded, the line will heat up and stretch, causing sag to increase (possibly down to 20').

What factors does potential energy depend on?
Height and mass
What two factors does potential energy depend on?
Height and mass
Which ball size will bounce the highest?
Bounce height will not depend on the ball's radius. It will however depend on the material of the ball and the speed at which it hits the ground
Why does the height of a ball decrease every time it hits the ground?
The height of the bounce decreases because of many factors but two main factors are gravity and friction. * * * * * Gravity has nothing to do with the decrease in height. The two main factors are friction and the fact that the collision is not elastic.
Is 112lbs heavy for a 13 year old?
It would depend on two factors: is the child male or female; and what is their height.
How are electric current and potential difference related?
Potential engergy is the engergy an object has based upon the height from the ground. Electric current also seeks an electrical ground. The symbols and equations are quite similar as I recall in my Physics.
What factors determine the gravitational potential energy of an object.?
Height above the ground, and mass of the object itself.
Is there a formula to determine the bounce height of a basketball?
No. The bounce height may depend on a variety of factors, especially the hardness of the floor, and the properties of the ball, including the amount of air it has.
What are two main factors that affect where groundwater becomes surface water?
The height of the water table and the height of the ground surface. Got it from past TAKS tests.
What is the overall height of a school bus from ground up?
Even if you are referring to a big school bus, the overall height will depend on the model. Excluding clearance markers, antennas, etc, the average height is 10-12 feet.
Which two factors does gravitational potential energy depend on?
mass m and height h Potential Energy = mgh where g is acceleration of gravity
Height of electric poles in India?
height of electric pole in India is 8m in residence area.
