In mechanics, mass has two defining attributes: Firstly, it is susceptible to a gravitational field. Secondly, attempts to accelerate a given mass m will face a resistive force of magnitude F=-p´/2m (p=impulse), or in the simple non-relativistic version: F=-ma, where a is denoting the degree of acceleration. Resistive in this context means, that a change of velocity comes at a price W(ork)=F*distance. In short, Mass has inertia.\n\nLet us now have a look at the situation with electrical self inductance. Self inductance L is the principal defining attribute of a coil. What does that mean? Imagine a superconductive coil with shortwired contacts, holding a stationary current going round in circles endlessly just like an ideal gyroscope in mechanics. There is also a constant magnetic Field B because of the current. \n\nHere comes the tricky bit: Think of a current I going in circles, and I´>0 would be giving the current gyroscope another spin. Any such attempt to increase the  current would again have to cope with some resistive "force" just as it was the case with our mechanical analogon. \nThis "force" appears now in form of the induced voltage U_ind = - L*I´. The more you increase the change rate of the coil current, the harder the current will have to stand up against the inversely directed voltage. All numbers here are governed by the self inductance L, which  is quite literally the coil's "magnetic inertia" (c.f. mechanical analogy).\n\nHope that helps.

The symbol for electrical load is Z called impedence.\n\nThis consists of the inducticve reactance, capacitative reactance and ohmic resistance.

In alternating current circuits, energy storage elements such as inductance and capacitance may result in periodic reversals of the direction of energy flow. The portion of power flow that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as real power. That portion of power flow due to stored energy, that returns to the source in each cycle, is known as reactive power.

It doesn't really have one. Its just a useful way of characterising the battery's behaviour.\n\nBatteries approximate to perfect voltage sources - in other words, the voltage across them does not drop no matter how much current you draw. (By contrast, solar cells approximate to perfect current sources).\n\nOf course, in reality the voltage does drop a little, and drops more the more current is drawn. The relationship is almost a straight line for small currents, and so it is useful to know the rate the voltage drops as the current increases, or dV/dI. Now of course the units of volts/amps is ohms.\n\nWhere this relationship is linear (small currents) you can also usefully include the internal resistance as a fictitious resitance in a circuit - it will do just as well as accounting for the change in voltage (can you see why?).

Impedance is related to alternating current Circuits.\nResistance is related to direct curent circuits. It has the Unit of inverse velocity. hence resists the motion of electrons in a conductor and as a result dissipates heat energy.Hence it is considered as a heat dissipating device..\n\nReactance is an energy storing device and is associated with coils which are magnetic energy producing device.\n\nHence a reactance stores energy and then gives it back .\n\nImpedeance is the sum of resistance  plus reactance but reactance is 90 degrees out of phase. Hence reactance is \ndescribed as imaginary quantity where resistance is real quantity.\nResistance is real because it dissipates energy and reactance is imaginary be cause it stores energy as magnetic and does not dissipate as heat energy.\nImpedeance in a circuit folows the same circuit rules as resistance.

Pulling quickly. Inertia is the reluctance of an object to change its state of motion, i.e from stationary to moving. You can see it as a delay in time that an object takes. And that's what you have to make use of. In other words, before the entire tissue roll starts to unroll after it experiences a force (by your hand on the piece of tissue), the tissue MUST come down.\n\nHope this helps=)

because the capacitor impedence = 1/ jwc ... for the dc current .. the frequency is equal to zero .. and w = 2(bi)f ... > w=0 .. the impedence = 1/0 = infinity ... so it's considered as an open circuit for DC

First problem: You have assumed all the mass of the meter stick is concentrated at the lower end; obviously, it is uniformly distributed along the length of the stick.  Assume that the mass is concentrated at the center; then, the length of the oscillator will be 0.865 meters, and the period should correspond.  There are some complications involving moment of inertia which I am ignoring.\nSecond problem: You may be solving for the wrong thing.  It looks like you are solving for the frequency of oscillation, rather than the maximum speed of motion.  Some careful work with units will help show you what is going on.

Definitions of inductance on the Web:\n\n    * The property of a circuit or circuit element that opposes a change in current flow, thus causing current changes to lag behind voltage changes. It is measured in henrys.\n      http://www.birnbach.com/TechnicalInformation/glossary/I.htm\n\n    * The property of an electric circuit that opposes a change in current flow.\n      http://www.customautosounds.com/faq.html\n\n    * (L) In general, the ability of a conductor to produce a magnetic field. In particular, magnetic flux divided by current, measured in henries (H). L=F/I. Or, the voltage (back emf) a conductor generates divided by rate of change of current in that conductor (self inductance) or another conductor (mutual inductance). L= -V/(dI/dt), where dI/dt is the rate of current change.\n      http://www.rcmicroflight.com/library/glossary.asp

Fosters reactance theorem \nThe Foster Reactance Theorem states that the poles and zeros of a reactive impedance function determine the frequency characteristics of the impedance. The poles and \nzeroes must alternate.\n\n\n(try some other sources,this may not b fully reliable)

The induction motor sets up a rotating magnetic field due to the phase lag batween the phases. This magnetic field "chases"  the rotor and tries to get it to rotate at the same speed. Ideally, if the motor is \n1. not loaded, and there are no losses due to \n2. friction, \n3. eddy currents, \n4. induction and \n5. resistance losses, \nthe rotor *will* catch up with the magnetic field and would rotate at the synchronous speed. \n\nHowever the world we live in is not ideal. All the losses mentioned above gets the rotor to always fall slightly behind the speed of the magnetic field. The difference is called Slip.\n\nNow if you load the motor, the rotor falls more behind the synchronous speed, kind of like the load is slowing it down. Larger the load, larger the slip. \n\nAnother way to look at this: If you study the speed torque characteristics of an induction motor, the torque at synchronous speed is 0. So if a rotor manages to catch up with synchronous speed, there is no more torque acting on the rotor, so it slows down again ever so slightly (due to various losses). as soon as it slows down the torque kicks in again and pushes it towards sync speed. the end result is that the rotor always is "almost at" sync speed. most motor designs have max torque at about 90% sync speed.

Think about the simpliest capacitor. It is clear that two metal plates that don't touch won't let a DC current pass, right? But the spacing is very thin so that the plate's charges can effect one another. When you first put current (even DC) to a discharged capacitor, it charges up and for a brief time it does conduct current. How long? Well it will charge to 2/3 of the total voltage in RC seconds (where R is the resistance of the circuit). So when AC current is "fast" enough, the cap is constantly in a charge/discharge state and current flows. The effective resistance (reactance) of the cap is 1/(2*pi*F*C). So the resistance goes down as the capacitance and the frequency rises.\n\nThe inductor, on the other hand is just a coil of wire. Again, it is easy to imagine that it will conduct DC. But when you first apply current (even DC) to a coil, the magnetic field will interact with the coil and produce an opposing voltage. This only occurs when the magnetic field is forming or collapsing (remember, magnetic fields that do not move do not produce electricity). So right when you change the current, the inductor will "resist" the change, but if the current doesn't change, it is just a wire. The reactance of a coil is 2*pi*F*L, so the resistance increases with frequency and inductance.\n\nNow, combining inductors and capacitors is another interesting subject, but you didn't ask about that....
