Four students are having a discussion about the question, "What is gravity?" Student A: "Gravity is the force that pulls stuff down."
Student B: "I read somewhere that gravity is an attractive force, and it exists between all objects that have
mass."
Student C: "That doesn't make any sense. If that's true, then why don't all objects start clumping together and
moving toward each other?"
Student D: “Doesn't it have something to do with the size of the objects? You're pulling on objects, but Earth is
bigger, so it has a stronger pull."
Question 1
How would you respond to each of the students?

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
