Jerimiah is studying wave a and wave b. wave a is traveling at 3 hertz, and wave b is traveling at 1.2 hertz.

what can be predicted about the waves if they were to crash into each other?

refraction would occur.
interference would occur.
the resulting wave would travel at 4.2 hertz.
the crest of wave a would overlap the trough of wave b.

Select all the correct answers. which statements fail to meet the requirements of a scientific claim? a) in the final 100 meters of a 10,000-meter race, an athlete's speed is more strongly related to anaerobic efficiency than to aerobic efficiency. b) flowers that reflect the most ultraviolet light are more likely to attract bees and other pollinators than flowers that reflect less ultraviolet light. c) even though evidence indicates that the solar system's planets follow elliptical paths, copernicus's model involving circular orbits is true. d) the evidence supporting newton's laws of motion was accurate in newton's time, but the universe operates differently today.
