What is the name of semicircle joining the poles?
tne name of the semicircle joining the poles to poles is called merdian
What is the line between the two poles called?
The lines joining the two poles are longitudes.
If Two vertical poles have heights 6 ft and 12 ft a rope is stretched from the top of each pole to the bottom of the other how far above the ground do the ropes cross?
For this particular problem, the point of intersection is 4 feet above the ground.The general formula for this situation is as follows:Let h=height of the shorter poleLet H=height of the taller poleThen the height of the point of intersection, let's call it y, will bey = (hH)/(h+H) or more symmetrically, 1/y = 1/h + 1/HThis may be deduced by simple algebra and the comparison of sides of similar triangles.An interesting aspect of this problem is that the distance between the poles does not appear anywhere in the solution! No matter how far apart you stretch the poles, the height of the point of crossing remains the same - it just slides along a horizontal line at the calculated height.Another point of interest is that the ratio of the horizontal distance from one pole to the crossing point ( call it x ) divided by the total distance between the two poles ( call it D ) also remains the same as the poles are moved apart. Specifically,(x/D) = H/(h+H) = (a constant for a fixed set of poles)
What are the endpoints of the axis of globe are called?
The ends of the axis are the North and South Poles.
What is the Imaginary circle passing through the poles now called?
International Date Line
Are lines of latitude perpendicular parallel or intersecting?
Lines of latitude are horizontal and run parallel to the poles
What is the measurement of the telephone pole?
How deep do they put telephone poles in the ground
Why are telephone poles called telephone poles?
Telephone poles are just wood poles that hold the telephone cable,the telephone terminal and telephone drops, (wires going to individual houses) in the air and out of the way. Areas that have no poles usually are newer areas, they have the same type wires only they are buried in the ground.
Which objects must be perpendicular to the ground if the ground is flat?
Objects like walls, poles, and trees must be perpendicular to the ground if the ground is flat. This ensures that they are standing upright and stable on the level surface.
How many telephone poles in the US?
There are approximately 120 million telephone poles in the United States.
Can line of latitude be thought of like telephone poles?
Yes, you can think of lines of latitude as running parallel to each other like telephone poles. They are imaginary lines that circle the Earth horizontally and are used to measure distances north or south of the Equator. The Equator itself is at 0 degrees latitude.
Do the longitudinal lines run parallel to the Equator?
No, the longitudinal lines run perpendicular to the Equator, from the North Pole to the South Pole. They converge at the poles and are farthest apart at the Equator.
What are 3 qualities of the lines of longitude?
-- they are semi-circles -- they are not parallel -- they join the north and south poles -- they are perpendicular to the equator -- the higher the latitude, the closer together any two longitudes are -- at the poles, all longitudes are the same point -- for every longitude west, there is an equal longitude east
Is the Equator a parallel line?
Meridians are imaginary semi-circles that connect the north and south poles. Parallels are imaginary full circles around the Earth, and every point on a parallel is the same distance from a pole. The equator is the longest parallel. Every point on it is equal distances from both the north and south poles. The latitude of the equator is zero, and all other latitudes are measured from it.
What are the effects of creep?
tilted telephone poles, ect.
What are telephone poles worn down by in the dessert?
sand
How many telephone poles are in one mile?
