Answer:
If light passes in an angle to a surface with a particular refractive index it refracts. This change in direction is due to a change in velocity. As light , for example, travels from air through water, it slows down, allowing it to continue travelling at a different angle or direction.
Step-by-step explanation:
H(3.2) represents the height of a rock 3.2 seconds after it is propelled by a slingshot.
Answer:
3 + (2 + 5) =(3 + 2) +<u>5</u>_
3 + <u>9</u>_ = 9 + 3
A/4 + 2 = 6....subtract 2 from both sides
A/4 = 6 - 2
A/4 = 4...multiply both sides by 4, eliminating the 4 on the left side
A = 4 * 4
A = 16
-4 = r/20....multiply both sides by 20, eliminating the 20 on the right side
-4 * 20 = r
-80 = r
