colour
Explanation:
chromatography differentiate out parts of solutions as in the form of different colours
The angle turned is obtained as 3.77 rads.
<h3>What is the angle of rotation?</h3>
We have the following information about the disk;
velocity 1= 7200 RPM
velocity 2 = 0 RPM
time taken = 0.01 seconds
We must convert from RPM to rad/s using the relation;
2π·7200/60 = 754 rad/s
Using;
θ = ωavt
θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds
θ = 3.77 rads
