If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and this wave exhibits reinforcement, the component waves must
a. be traveling in the opposite direction of the resultant wave.
b. have a different frequency than the resultant wave.
c. be in phase with each other.
d. have a different wavelength than the resultant wave.

Energy is the ability to do work which measures what

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
