Questions: -What do you observe on the filter paper strip after 2 to 3 hours?
-What conclusion can you draw from this experiment about the components of the black ink?

Tbh i cant really see the words do u ming taking an upclose picture?

First part- As the water moves upward along the filter paper strip, the different pigments present in the black ink separate out as different points. After drying the paper, there is a colored pattern on the strip.

Second part- Black ink is made up of different colored pigments, and chromatography separates it into its constituent components.

Explanation:

Plato

yes it is balanced

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
