<h2>Answer: a. Yellow
</h2>
According to the additive theory of color, when we join the <u>three primary colors of light</u> (Red + Green + Blue) we get White light.
On the other hand we have <u>secondary colors of ligh</u>t that are:
Yellow = Red + Green
Magenta = Blue + Red
Cyan = Blue + Green
Now, if we know that:
Red + Green + Blue = White
And:
Red + Green = Yellow
Then:
<h2>Yellow + Blue = White</h2>
Seriously this is fun dont know why u want me to enjoy this so ummmm hmmm lolololol the equation for this would be s=vif+1/2at^2 so time is lets see plug it and vell vi=0 since it started from rest so s=1/2at^2 and plug it in the displacement and time 110=1/2 a 5.21^2 and solve it and u get 8.1m/s^2
C. Because they are in the same group, so they have the same number of valence (outer) electrons
it forms a system because a system contains two or more organs or structures
