Well , infact i was searching for some docs on SI , and I came across this question. I think I can give you a brief idea about your query Decoupling means to disconnect- Decaps are used to decouple one part of electrical n/w from other. noise caused by other elements are bypassed to ground by this capacitor and thus it nullify the effect. Dynamic IR is all abt the Ldi/dt effect of the wires. The capacitor will try to cancel the inductive impedance

What is dynamic stretching?

"Dynamic" means that you are in motion while you perform the exercise. An example of dynamic stretching would be putting your toes on the edge of a step and bouncing as your heels drop below the edge. This would stretch the gastrocnemius. Dynamic stretching can be dangerous because it can lead to muscle tears and other injuries if done improperly so you should learn proper stretching techniques from a qualified trainer.
