If there aren't any road improvements needed, such as adding turn lanes, then a complete traffic signal system for a typical four-way intersection will cost about $250,000 to $300,000. When additional costs like control equipment, project inspection, and design are taken into account the cost edges closer to $300,000.f there aren't any road improvements needed, such as adding turn lanes, then a complete traffic signal system for a typical four-way intersection will cost about $250,000 to $300,000.

Magnification. Magnification produced by a spherical mirror gives the relative extent to which the image of an object is magnified with respect to the object size. It is expressed as the ratio of the height of the image to the height of the object. It is usually represented by the letter m. If h is the height of the object and hâ² is the height of the image, then the magnification m produced by a spherical mirror is given by. The magnification m is also related to the object distance (u) and image distance (v). It can be expressed as:
The magnification you will get for your telescope is given by: magnification = (telescope focal length)/(eyepiece focal length) To look at planets like Jupiter and Saturn, you will need a magnification of about 180; with that you should be able to see the planets and their moons. If you want to look at the planet alone with higher resolution, you will need a magnification of about 380.
