The Mathematics of Lenses
Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a lens. The use of these diagrams was demonstrated earlier in Lesson 5 for both converging and diverging lenses. Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a quantitative form. While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and image size. To obtain this type of numerical information, it is necessary to use the Lens Equation and the Magnification Equation. The lens equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f)
Answer:
No element gains 4 electron in the case of transition element they bonds with covelent bonding whereby the electrons are shared around the last orbits
Explanation:
Answer:
Coefficient of friction is the ratio of friction force to normal force.
μ = F/N
Answer:
A
Explanation:
the current passed in car is fixed and responsible for electric devices in car moves in one direction only but there are some cars has alternating cars to make induced current in its coils allowing it to move without fuel(as exception)
911.1×155.9 = 14,202.49
14,202.49 in 3 significant figures would be either 14,200 or 1.42×10^4
