If a scientist is studying a model that is a widely accepted theory about the position of planets and sun, the model would most likely help the scientist to understand facts that can't be easily observed. That will make the correct answer to be C.
Answer:
v= 4.9 m/s in east direction ( or v=4.9 m/s * i )
Explanation:
Since the passenger moves along the train ( in the north direction relative to the train) then if the train is traveling east relative to the ground , the passenger will also travel to the east relative to the ground .
Then the magnitude of the velocity will be
v= 1.40 m/S + 3.5 m/s = 4.9 m/s
v= 4.9 m/s
and the direction will be east ( if the x axis represents east direction and y-axis the north direction , then the velocity vector will be v=4.9 m/s * i )
Wave speed = (wavelength) x (frequency)
Wave speed = (0.5 m) x (2 /sec)
<em>Wave speed = 1 m/s</em>
