The drawings show two examples in which a ray of light is refracted at the interface between two liquids. In each example the incident ray is in liquid
A and strikes the interface at the same angle of incidence. In one case the ray is refracted into liquid
B, and in the other it is refracted into liquid
C. The dashed lines denote the normals to the interfaces.
D. Rank the indices of refraction of the three liquids in descending order (largest first).

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
