Magic Jack is available at numerous online stores as well as many retailers in North America and Europe.

Prices vary significantly so it is worth shopping for the best price.

Typical life? Some go in toys, others go in missiles. They range from blinking lights in the store to solar panels on your roof.

Life span can be a few seconds to many decades. Some semiconductor facilities have failure rates of over 50%. I would guess the typical life would be getting thrown away after test would be the closest to typical.

Statics deals with stationary objects(bridge). Dynamics deals with things in motion(cannonball).

A Civil Engineer deals with statics a lot more. They design buildings, bridges, roads, ect.. to NOT MOVE. In fact, in Civil Engineering if something moves it is Failure! That is how failure is defined.. movement.

A Mechanical Engineer deals with dynamics a lot more. They design machines, mechanisims, and things with moving parts. Like levers, pulleys, etc. They WANT things to move and design them accordingly.

The study of Statics (objects at rest) and Dynamics (objects in motion) is the basis for much of engineering. Along with a class called strength of materials, which deals with the mechanics of the materials used in the machine, building, etc.

Assuming that the receiver uses a high-side local oscillator and an IF of 455 KHz,

the image frequency is 910 KHz above.

When tuned to 1600 KHz, the image frequency would be 2,510 KHz.

Resistance is decreases then the voltage drop across it is decreases because of ohms law (V=IR),due to this power can also be decreases because of P=VI. so finally we can say that resistance decreases ,power also decreases.

What kind of a charger it this? You should check the manual first.

It may mean several things. Maybe there's no equipent ground on the outlet you are using. Or maybe the battery draws unexpectedly high current, like there is a short circuit in it, etc. etc...

In metal conductors, an electric current is a drift of free electrons from a negative to positive. Period! 'Conventional' current (positive to negative) is, as its name indicates, nothing more than a convention -based on an assumption made before the true nature of electricity was determined. In other words, it doesn't exist! So no experiment can 'prove' that conventional current exists because it doesn't exist!

The direction of conventional current was based on the assumption, by the likes of Benjamin Frankin, who assumed that an electric current was some sort of fluid which, of course, would flow from a high (positive) pressure to a low (negative) pressure. The discovery of the structure of the atom confirmed that a current (a flow of electrons, in metal conductors) flowed from negative to positive.

Think of it this way. When you look at a led display in a waiting room ('take a ticket'), are the illuminated leds moving to the right, or are the unilluminated leds moving to the left? Think of the illuminated leds as electron flow, and the unilluminated leds as conventional flow.

Then the brightness of the light buld increases.

an Hartley oscillator uses a tapped inductor ( i.e an inductor with an additional connection at a suitable position in turns of the coil. ) with a specific tap ratio as per the circuit gain and design. For Low Frequency oscillators large inductances are required which have large number of coil turns. It is possible to get suitable ratios for such values hence this circuit is prefered.

The feed back factor in the oscillator refers to the output which is usually sinusoidal.

Resistors are tiny devices on circuit boards. Prices should range but should not be expensive but dependent on the materials used and the nature of conductivity.

This might be a description of a radio antenna.

This refers to the voltage Vds that counteracts the opening of the n-channel (NMOS), at the drain end. Since the width of the channel is a function of Vgs - Vtn, the mosfet saturates (pinches off) when Vds is greater or equal than/to Vgs - Vtn.

Wave carriers are aircraft carriers that are being crushed by giant waves.

From about 9 kilohertz (kHz) to thousands of gigahertz (GHz). This portion is referred to as the RF Spectrum. As the frequency is increased beyond the RF spectrum, electromagnetic energy takes the form of infrared (IR), visible light, ultraviolet (UV), X rays, and gamma rays.

The ranges, or frequency bands, are as follows.

3kHz to 30kHz v.l.f. Very low frequency

30kHz to 300kHz l.f. Low

300kHz to 3MHz m.f. Medium

3MHz to 30MHz h.f. High

30 MHz to 300MHz v.h.f. Very high

300MHz to 3GHz u.h.f. Ultra-high

3GHz to 30GHz s.h.f. Super-high

30GHz to 300GHz e.h.f. Extra-high

It is a variable resistance.

As you turn the volume control from low to high - or press buttons to do the same thing on miniature electronic items like mobile phones and MP3 players - the resistance of the volume control is reduced so that a higher current carrying audio waves can get through to the amplifier and so to the item's loudspeaker or headphones.

AM means Amplitude(=height) modulation, so the frequency stays the same and the message is coded into variations of the strength of the signal.

FM stands for Frequency modulation. Here the strength of the signal stays the same and the message is coded into changes in frequency instead.

the power can flow either way through autotransformer (345/120 kV) ?

To determine the wavelenght of a signal, invert it. This would take 88.9 MHz, invert it (1/88.9) giving you 0.01125 microseconds. Now, determine the speed of the signal. Generally, for an FM radio signal, the speed is the speed of light, which is 3 x 108 meters per second. So multiply 0.01125 by 3 x 108, giving 3.75 meters. The question asked for nanometers, so multiply by 1 x 109, giving 3.75 x 109 nanometers for a signal frequency of 88.9 MHz.

2.4GHz microwave, a band assigned for low power unlicensed users (including microwave cookers) that must tolerate interference from any other user of the band, even if the interference makes them inoperative.

I think g is also allowed on 4.8GHz microwave.
