Answer» Answer: 1)Friction depends on the smoothness or roughness of the two surfaces which are in contact. A rough surface produces greater friction as COMPARED to a smooth surface. 2)Laws of REFLECTION: The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane. The second law of reflection states that the angle of reflection is equal to the angle of incidence. 3)The top food sources of VITAMIN A in the U.S. diet include dairy products, LIVER, FISH, and fortified cereals; the top sources of provitamin A include carrots, broccoli, cantaloupe, and squash |
