What is the relationship between a reflected wave's "angle of incidence" and "angle of reflection"?
those 2 angles add up to 180 degrees
those 2 angles are always equal
those 2 angle add up to 90 degrees
the "angle of reflection" minus the "angle of incidence" equal 45 degrees

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
