Answer:
A
Explanation:
Frequency is defined by repetitions or periods per second. If we take any segment from each graph, we would see that graph A has the most repetitions per second.
The period of A is the shortest since the frequency is equal to 1/T, the smaller the period, the higher the frequency.
Blue light is scattered in different directions by tiny molecules of air in our Earth's atmosphere. Blue is scattered more than other colors because moves at shorter and smaller waves.
The sunset colors result from molecules and small particles in the atmosphere change the directions of light rays, causing them to scatter. The short-wavelength blue and violet are scattered by molecules in the air much more than other colors of the spectrum.
Answer: friction has no role to play in this case. because friction usually occurs between to parts which come in contacts. examples (a)our joints in the human body (b)two mechanical parts (shafts).
Explanation:
However what this topic relates to is gravity.
