Answer:
(1.9756, -2.1951)
Explanation:
The center of mass equation is: = , where m represents the masses and x represents the position.
In order to find the coordinates of the center of mass, we need to use this equation for both the x-values and the y-values.
<u>x-values:</u>
<u /> = = = = = 1.9756
<u>y-values:</u>
<u /> = = = = = -2.1951
<u>center of mass:</u>
(1.9756, -2.1951)
Higher frequency,higher energy,shorter wavelength
