    Natural vs supernatural question

    I think "supernatural" means some thing that occurs out of the predictable magnitude of the human's imagination. We generalize and predict what could happen or what suppose to happen, i.e. the brain-dead patient should never go out of his coma; nonetheless, it would be supernatural that one...

    Electron speed in wire in circuit

    Thank you very much for your reply, I am sorry I have apply my introductory physics into something that much more complex. Obviously, I have never had quantum machanic so pardon me. However, it is quite interesting that I now could see how Newtonian physics fail at the quantum level. Thanks all!

    Electron speed in wire in circuit

    But according to kinetic energy this small force would provide an enormous velocity (E = 1/2mv^2) to the electron that has mass m= 9. X 10^-31kg. Nonetheless, I would interest in in drift current. This may answer my question. So please give some more explanation if you can. Other argument...

    Electron speed in wire in circuit

    I do not agree because the electron would have so great speed from the electric force. I would move through the wire at any length in very little time. Furthermore, the electron would not have to collide with the atoms along the wire.

    Electron speed in wire in circuit

    I do not agree with the "answer" below. What do you think about it? Question: When you turn the key in an automobile, you complete a circuit from the negative terminal through the electric starter and back to the posstive battery terminal. This is a DC circuit and electrons migrate through the...

    Does everthing have life?

    My sincerity! From: wargreymonkktl To: prtcool I have seen a little confusion in your perception about physical elements and metaphysical elements. Let me explain in just a minute! 1. First of all, it is not logically to tell that human can physically create souls since soul in a...

    Is there any difference between Miscible and Soluble?

    I think To my best understanding that the words miscible and soluble that our friend mentioned here is talking about the physical properties of the solute and the solvent. as I know that when we mix substances together they are aither miscible or unmiscible. However, "soluble" refers to...

    How is knowledge transmited?

    When you talk about how the texts were write. You must look for what the purpose of these text. Obviously, You will not expect a high school student to read the book of college students and so on. We must look at who were the authors of the book that we are reading. you will not expect that...

    The Ultimate Question

    how about he has a booms that when it exploded it will make the matter become anti-matter and it means that the atoms will be vanished because we talk about conservation law only applies for matter. can you answer me that antimatter will follow the conservation law too? i am crazy to put that...

    Integration of newton equation?

    integration of newton equation??????? Newton's second law is insufficient to describe the motion of a particle. In addition, it requires a value for F, obtained by considering the particular physical entities with which the particle is interacting. For example, a typical resistive force may be...

    Throwing a tennis ball through a wall

    as you say that the quantum theory does not describe the macroscopic object tive. but a macroscopic object are compose of the "quantum" particles.there must be a relationship between them. there must be a possibility that it will tunnel through the wall is we can give the ball a motion so that...
