The quantum mechanics states that there is not any interaction between an accelerating electron and atoms...
Homework Answers
The free electrons are distributed randomly within a perfect crystal. If applying an external electric field, all free electrons are tending to polarise opposite direction to the electric field. Because of an electron is a negative charge carrier. These accelerated free electrons are provided the current. If the increase in the electric field, the current will increase. After some time providing current becomes saturation due to all free electrons are polarized in one direction at a particular value of the applied electric field. Thus, if an increase in the electric field beyond that the particular value of the electric field, the current remains the same ( saturation value).

You sometimes create a spark when you touch a doorknob after
shuffling your feet on a carpet. Why? The air always has a few free
electrons that have been kicked out of atoms by cosmic rays. If an
electric field is present, a free electron is accelerated until it
collides with an air molecule. It will transfer its kinetic energy
to the molecule, then accelerate, then collide, then accelerate,
collide, and so on. If the electron

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
