Answer: A) black
Explanation:
Let's begin by explaining that a primary color is one that can not be obtained by mixing any other color. In this sense, red, green and blue are the primary colors of light (using the additive theory of color), but not the primary colors of the pigments.
For the case of pigments (using the subtractive color theory) the primary colors are cyan, magenta and yellow. This is because the pigments generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.
Hence, according to the subtractive theory, if we join the three primary colors of the pigments, we will obtain the black. Unlike the additive theory of light, in which if we join the three primary colors we will get white light.
This means:
If a paper that absorbs red-orange-yellow-green-blue-indigo-violet is illuminated with white light, the collors our eyes will see is black.

Answer:
B 23m/s
Explanation:
From the above information we get,
Initial velocity= 3m/s
Acceleration by gravity = 10 m/s2 (approx)
Time taken =2 seconds
v=u+at (First Equation Of Motion)
v= 3 + 10 × 2
v= 23 m/s
Answer: 1.2%
Explanation:
Given
If one borrows $12,250
and give $147 interest on it
Then the interest is given from the formula
Thus, the annual rate of interest is 1.2%
