HEYYY EVERYONE !! PLEASE HELP! <33 There are many diseases that can affect the eyesight of people. These diseases are often caused by many different things such as poor nutrition, heredity, or accidents. Choose a disease that affects the eyes and research it, then write an informational brochure about the disease. Your brochure should include what the disease is and how it is caused, how the disease can be treated if the disease can be prevented, the effect it has on your eyesight, pictures of your disease, and any other important information about the disease. Have great day!

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c. m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
