Complete the passage with the options that explain why converging lenses are used to correct farsightedness (hyperopia), whereas diverging lenses are used to correct nearsightedness (myopia).
In order to see an object, the cornea and lens of the eye form an image directly on the retina. The eyes of a nearsighted person cause the light rays of a object to converge too and therefore focus the image the retina. A diverging lens placed in front of a nearsighted eye compensates for the convergence so that an image forms properly on the retina. The eyes of a farsighted person cause the light rays of a object to converge too and therefore focus the image the retina. A " converging lens placed in front of a farsighted eye compensates for the convergence so that an image forms properly on the retina.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
