1 The spaceship at S wishes to touch the surface of the giant planet and proceed to point X in the shortest distance possible. To what point P on the planet surface should the spaceship travel? 1. Point a 2. Point b 3. Point c 4. Actually, all yield the same total distance.

2 The spaceship at S wishes to touch the surface of the giant planet and proceed to point X in the shortest distance possible. To what point P on the planet surface should the spaceship travel?

13 Suppose you want to send a beam of laser light to a space station above the atmosphere and just above the horizon. You should aim your laser 1. slightly higher than 2. slightly lower than 3. directly along the line of sight to the space station.

17 The photographer wishes to photograph the rainbow but is disappointed to find the cameras angle of view is not wide enough to see the whole rainbow. To get the whole rainbow, she would be better off if she were 1. closer to the rainbow. 2. farther from the rainbow. 3. … neither, for shed get the same portion of rainbow in either case.
