Why do supermarkets sell clothes and electronic equipment?
Because they want to make themselves look like walmart. They want to make more money so they sell other stuff.
A DC jack exists for the purpose of supplying direct current to a device from an external source, as opposed to the batteries inside the device. The external DC power would likely come from an AC to DC adapter that you plug into the wall. Such a jack can also work with car adapters too, provided it it converted to the correct voltage. So using an external source keeps you from using the batteries. With some equipment, that can charge the battery as well, but devices using disposable batteries are wired as to not charge the batteries.
What is purpose of Electronic medical records?
Electronic medical record (EMR) systems assists health care professionals to store and share patient information across disciplines and across facilities. The EMR system "provides timely and efficient access to medical records without compromising patient privacy, and allow[s] patients to engage in their own health care" (Jerome, DeLeon, James, Folen, Earles, & Gedney, 2000, p. 409). The EMR is a computerized patient charting system. Computerized charting allows for entry of interdisciplinary data and examination of specific patient information. Computerized charting of assessment data, diagnostics, interdisciplinary treatment plans, and evaluation of treatments enhances continuity of care across shifts and across disciplines. Computerized charting requires that a minimum standard is documented, preventing the omission of essential patient information.

Locking goods into place or having them monitored by electronic systems is known as what?
Target hardening
Are there any devices you can use to mess up pot o gold machines to pay out?
A high powered magner attached to the side used to work, but now technology has made pretty much any tampering impossible, sorry. Tbh the prison sentence wouldn't be worth the payout.

How stagger tuned amplifier works?
This deals with detailed information about filter theory.
One source is the Van Valkenburg and Shaman text Analog Filter Design.
Another text is by Chen, similar title.
Putting three poles at the same break frequency reduces the bandwidth.
At the designed corner frequency the gain response is now down by 9 dB so
the 3 dB point is pushed to a lower frequency.
Stagger tuning gives the three pole roll off but also maintains the designed bandwidth.
For example:
If you want a three pole Butterworth characteristic you can use a state-variable op-amp network tuned to have a Q of 10 (or a zeta of 0.5, depending on your background) and a single LPF op-amp stage.
Neither of these is tuned as a Butterworth but together they give the effect of a three pole Butterworth.
The State Variable op-amp network has several other names such as the Tow-Thomas Biquad or the Huelsman-Kerwin-Newcomb network.
It can provide a biquadratic function, meaning a quadratic in the numerator and a quadratic in the denominator.
12v means it is suitable for any 12v dc current purpose
the 18ah means it has an amp hour rating of 18 its a measure of how long the battery can work from full charge until it would need to be charged again
ex. the bigger the ah rating the longer you could turn the starter for before the battery would run flat

What does the CE on electronics' labels mean?
It means that it complies with ALL relevant European community standards.
Brief explanation about the types of waveguides?
A waveguide is a structure which guides waves, such as electromagnetic waves or sound waves. There are different types of waveguide for each type of wave. The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves.
Waveguides differ in their geometry which can confine energy in one dimension such as in slab waveguides or two dimensions as in fiber or channel waveguides. In addition, different waveguides are needed to guide different frequencies: an optical fiber guiding light (high frequency) will not guide microwaves (which have a much lower frequency). As a rule of thumb, the width of a waveguide needs to be of the same order of magnitude as the wavelength of the guided wave.
Can you heat your water with a 9v battery?
Sure. But not much water, a 9 volt battery has very little power (energy).
What is the difference between HTTP and HTML?
HTML is a description "language" for how to present information that passes via http, HTML stands for Hyper Text Markup Language and has multiple "versions" that change as our use of the world wide web changes.
Hyper Text Transfer Protocol, http, is a computer protocol or set of procedures, describing how computers may pass information in an orderly fashion. The great thing about http is it is not just related to one single protocol but is built to deal with a conglomeration of many protocols allowing different things to be handled easily in one well known package.
Http says how to pass the info, HTML says how to organize the raw data and present it at the other side.
HTML is one of many markup languages (SGML, XHTML, DHTML...) but is the most used as it was the one chose to present info over the world wide web.
Buy an unrestricted CDI unit. I would suggest Daytona. Be sure to check how many pin's you have, so you know that it is going to fit.
What are advantages of gas insulated sub station?
it requires lesser space compare to normal. design of switch gear is more compact , has the potentials to increase system reliability and has less maintenance and longer service life.
A PNP transistor can be used as a power amplifier in a circuit because it can handle high power levels and provide amplification by controlling a large current with a small input signal. In Figure 52, the PNP transistor is configured in a common emitter configuration, allowing it to amplify the input signal by controlling the current flowing through the load connected to its collector terminal. The transistor acts as a switch that modulates the output current based on the input signal, providing amplification of power.
Does Fry's Electronics Drug test employees?
Yes, their application refers to a 'test for substance abuse;' it is a urinalysis test for "abusive levels of any chemical substance." The vague statement is from the application. Unsure what type of urine test it is.

what is the main difference between electrical and electronics ?
In short: electrical circuits handle transfer of energy - electronic circuits handle transfer of information

We only need the information to answer the question.
What is difference between coaxial cable and twisted pair cable?
The answer is in the name of the cables; co-axial cable has an outer an inner part which share a common axis (hence the name co-axial). Usually the outer part acts as a screen to protect the inner part from electrical interference. Twisted pair cable consists of a number of pairs of cables. Each pair is twisted together and is used for a single signal; one side of the pair sends the normal signal, the other sends the inverted version. At the receiving end, the normal and inverted signals are subtracted, because any electrical noise is likely to affect each of the pair of cables equally (because they are coupled together by being twisted), subtracting the two should produce a noise free resulting signal. There are variations; sometimes each pair is screened - improving the noise immunity, particularly from other signals in the same cable - sometimes the entire bundle of cables is screened. Occassionally, both the individual pairs are screened and the bundle is also screened.
