Answer:
98N and 147N
Explanation:
We have the following information:
We can find the static fricton force as follow,
Where N is the normal force (mg)
Static friction force at 147N is greater than the force applied hence body does not move.

<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>
