Wavelength. Each wavelength is a certain color. For instance, shorter wavelengths (like 470nm) will be blue or violet, while longer wavelengths (like 650nm) will be red. Hope this helps! :)
You could attach the pulley to a secure object on the top of the ramp, and crank the pulley to bring the wagon up said ramp into a loading bay perhaps, or a track.
Hope I helped.
Its the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System.
Answer:
The resulting coordinate is
Explanation:
From the question we are told that
The mass of the first dice is 
The mass of the second dice is 
The mass of the third dice is 
The coordinate of the first dice is 
The coordinate of the second dice is 
The coordinate of the third dice is 
Generally the resulting coordinate of the center of mass of the dice in the x-axis is mathematically evaluated as

i.e the summation of the moments about their x-axis divided by the magnitude of their masses
substituting values


Generally the resulting coordinate of the center of mass of the dice in the y-axis is mathematically evaluated as



Thus the resulting coordinate is
