    Electric vs Magnetic Field: Transferring Energy

    I just want to clarify whether electric field is the one which can transfer its energy to some object while magnetic field cannot. If yes, how come magnetic field cannot transfer its energy?

    How does infa-red heat things up?

    'Temperature' of an object is related to the average energy of the particles make it up. The surface particles of the object will interact with the incoming infrared ray (which is an electromagnetic wave) due to the fact that particles are made of charges. This process of heat transfer is called...

    Sommerfeld quantization condition

    [b]1. The allowable radius of spinning electron in uniform magnetic field using sommerfield quantization condition [b]3. Subs mv/r=qvB and some of its variation (like th period 2pi*r /v) into the closed int of pdq=nh and I got r=sqr((nh)/(2pi*qB)). Is this correct. I can't find anything about...

    Measuring Young's Modulus: Clamped vs Freely Supported Ends

    I have a project to measure young modulus by measuring the deflection of a beam under point mass. I have derived the equation but i am confused to how the end of beam should be placed to obtained best precision. Should it be both clamped end, freely supported end or a mixture of both? My idea...

    Is (n!/n^n)*exp^n a Convergent or Divergent Summation?

    1)summation for n=0 to infinity for (n!/n^n)*exp^n. Can anyone help to prove whether this is convergent or divergent?

    Maximum Force Analysis for FB and FC Limits in a Tension System

    I think in this case Fc does not have vertical component, so we need not to care about it. the diagram try to fool us i think. so FA(max)=FB(max)=5kN.

    The Necessity of Supply: Maintaining Standing Waves

    sorry i think it is not quiite clear this is the full question. one end of a cord is attached to a vibrator while the other end is attached to a fixed position. a standing wave is resulted.althought energy is not transmitted by a standing wave, the vibrator must still provide power. Why is this?

    Does Newton's Third Law Explain the Different Fall Rates of Water and Glass?

    when air resistance is not negligible actually the water will be slower than the glass based on surface area and the glass assumed to have greater weight than total weight of water(under circumstance that the glass fall upside down position). and then the water exert force to the inner base of...

    Understanding Ultimate Ratio of Equality

    hi, 1)can anyone help me to understand ultimate ratio of equality? (from this extract) Cor. Hence if two quantities of any kind are any how divided into an equal number of parts, and those parts, when their number is augmented, and their magnitude diminished in infinitum, have a given ratio...
