Suppose an astronaut travels very fast from the Earth to the nearest star system, Alpha Centauri, located 4.30 light years (ly) away as measured by an Earth-bound observer. (a) How long does it take the astronaut to travel 4.30 ly at 0.99850 c (as measured by the Earth-bound observer)

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude. (brainiest if you get it right! ) ~kayla

If y gets smaller as x gets bigger and y have an relationship?

Place me with this question is my last question
