    Difference and benefits of qubits compared to regular bits?

    If I understand right: They are using statistics to know the state of a 2 bits after only measuring a single bit. The computations are more efficient this way. By using more fundamental mediums than coils (ram) or plates (hdd) to store information they can derive statistical methods for...

    We make the world by participating in it

    What does it mean to observe or measure something? A measurement is the act of determining the value of some observable. But this means the system is left in a state where the uncertainty of the observable vanishes, yes? Generally whatever the state of the system before measurement, at the...

    Circular Work Vs. Straight line work

    Well in one case the object is going straight up while in the other it is following a longer path. I suppose the question is if this effects the work. No machine can increase work (with the exception of my computer), so it should be the same, even though the force is multiplied by a longer...

    Circular Work Vs. Straight line work

    Work and energy are not equal though.

    Mass Defect & the Strong Force in Nucleons

    The binding energy is the energy required to bring the potential energy up to zero where the potential energy in the bound states is negative. The change in potential energy is due to the force. If an object is outside of the range of the force then there is not much potential for the object...

    Does Spin Have Rotational Kinetic Energy?

    I don't think it can be said that r=0 just because the particle demonstrates properties of a point particle. The concept of a point particle is still theoretical. Even if it was found that space was discrete and could have "points" would those points not have a volume associated with them...

    Photoionization what will happen to compounds?

    Yea, it really comes down to the binding energy of the orbital. There is a chart here for Si http://en.wikipedia.org/wiki/Electron_binding_energy

    Reference for the Temperature Dependent Speed of Sound in Common Solids

    I am not sure but since we are only talking 100's of degrees Celsius, not thousands I wouldn't expect so.

    Mass Defect & the Strong Force in Nucleons

    When the Nucleons are bound it is as if though they are in a non-inertial frame. Just like an object on Earth has less energy then an object further away, the nucleon has less potential energy in the bound state then they would in the free state. The energy is usually said to be potential...

    Reference for the Temperature Dependent Speed of Sound in Common Solids

    The effect on densities of solids between those temperatures is small. From wiki: "A one percent expansion of volume typically requires a temperature increase on the order of thousands of degrees Celsius." That is why you only find temp based charts for gasses. Just use a standard chart...

    Why weight on an incline is different?

    I would approach it as a simple misunderstanding, and that you thought it might be a trick question. Let he/she come to the conclusion that your brighter then the average, don't go in holding the attitude that you are.

    Why weight on an incline is different?

    Oh yes, if the question asks only "What is the weight" it is mg. That is almost like a trick question. However if the question is asking what the force is along the plane then it is not simply mg. The word weight is usually only used for something pressing straight down due to being in a...

    Why weight on an incline is different?

    grams are a unit of weight. Edit (opps a unit of MASS, not weight) (mass)(gravitational acceleration) is measured in Newtons which is a unit of force. F=ma The force along the plane is mgsin45 since the plane is at a 45 degree angle to the direction of force. So the force in both cases is mg...

    Conductor Tension Due to Birds Landing & Flying Away

    Are you talking about the tension on a line between the two poles or some sort of internal tension between the strands? For a line between two poles the tension never goes to negative (compression?) because of a perpendicular force on the line. The tension should only depend on the...
