the best option would be d.) examples of constructive erosion.
It is actually caused by the environment, so its false. :)
Answer:
The electrons in an atom can only occupy certain allowed energy levels. ... Only certain energy levels are allowed, so only certain transitions are possible and hence specific wavelengths are emitted when an electron drops to a lower energy level.
"The wavelengths are getting longer, meaning the star is moving away from the observer" is the one among the following choices given in the question that this means about the length of light waves and movement of the star. The correct option among all the options that are given in the question is the fourth option or option "D".
Answer:
0.65 m/s
Explanation:
Applying the equation,
v = u + at
35 = u + a×2.3 -(1)
Again, applying the equation,
s = ut + 
a
41 = u×2.3 + × 
35.65 = 2u + 2.3a -(2)
comparing first and second we get u= 0.65 m/s
