What is the value of retardation?

$\large{\mathfrak{\red{\underbrace{\overbrace{\orange{\boxed{\red{★Answer★}}}}}}}}$

An Rf value will always be in the range 0 to 1; if the substance moves, it can only move in the direction of the solvent flow, and cannot move faster than the solvent. For example, if particular substance in an unknown mixture travels 2.5 cm and the solvent front travels 5.0 cm, the retardation factor would be 0.5.

What is the formula to calculate retardation?

$\large{\mathfrak{\red{\underbrace{\overbrace{\orange{\boxed{\red{★Answer★}}}}}}}}$

What is the formula to calculate retardation?Retardation or deceleration is negative change in velocity per unit time. So, Here, retardation=change in velocity/time(seconds). Retardation= -acceleration

Answer 2

Answer:

a = Change in velocity/Time taken

So, you can get a negative acceleration value in the case of v<u, that is is known as retardation.
