It will make our life easier.
It helps us organize our daily activities.
This helps our work can be done faster.
Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture.
It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.

Answer:
3.24m/s^2
Explanation:
The following data were obtained from the question:
U = 4m/s
V = 16m/s
t = 3.7secs
Acceleration is change in velocity with time i.e
a = (V — U) / t
a = (16 — 4) / 3.7
a = 12/3.7
a = 3.24m/s^2
