1) If a boat is moving downstream, will the velocity of the boat relative to the water be greater than the velocity of the boat relative to the stream bank? Explain.
3. If an airplane is flying in the same direction as the wind, will the velocity of the plane relative to the ground be greater than, less than, or equal to the velocity of the plane relative to the air? Explain.
5. If a boat is moving across a stream, will the speed of the boat relative to the bank equal the numerical sum of speed of the boat relative to the water and the speed of the water relative to the bank? Explain.
7. Does the addition of the velocities of things like airplanes and wind speed require use of the special theory of rela-tivity? Explain.
9. Was the ether (the assumed medium for light waves) pre-sumed to exist in a vacuum? Explain.
11. Did the Michelson-Morley experiment succeed in measur-ing the velocity of the ether relative to the Earth? Explain.
13. Which of Einstein's postulates deals most directly with the failure to detect motion of the Earth relative to the ether? Explain.
15. A chess game taking place on Earth is seen by observer A, who is passing by in a spaceship. Observer B is stand-ing on Earth looking over the shoulder of the players. Which of these two observers measures the longer time for the interval between moves in the game? Explain.
