The formula of determining the 
value is:
where both the distance are measured from the common origin.
10 % ethyl acetate/ hexane means it has 10 % ethyl acetate and 90 % hexane which are non-polar in nature. Hence, the non-polar compound will travel farther in the TLC plate along with the eluent and the polar compound will travel less as they remain attracted to the polar adsorbent 
.
Among 3-decanone and 3-decanol, 3-decanone will have high as it is non-polar.
Among toluene and benzoic acid, toluene will have high as it is non-polar.
Among cyclooctane and cyclooctanone, cyclooctane will have high as it is non-polar.
A because it requires energy from food to move which is mechanical
21.9444....
To solve:
Distance / time!!
You can remember by a triangle...
/D\
| M T |
To find distance, MxT
To find mass, D/T
To find time, D/M

Answer: B
. particle size
Explanation:
Let's begin by explaining that a molecular sieve is a device, whose composition allows the absorbtion of molecules that are small enough to pass through its pores, since it is made up of small pores of a precise and uniform size.
Thus, very small molecules manage to pass through the pores of the sieve, while large ones do not.
So, based on this premise, a molecular sieve separates the substances by their size.
Hence, the correct option is B.
