While kayaking near Catalina Island, you look straight down into the water and notice a turtle staring up at you. Assume your face/eyes are about 1 meter from the surface of the water. The index of refraction of seawater is 1.4. Required:
a. If to you, the turtle appears to be 2 m below the surface of the water, how deep underwater is the turtle actually?
b. How far above the surface of the water does the turtle perceive you (your eyes/face) to be?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
