Microwaves are detected by a ghosts b electromagnetic fields c micowave ovens d cooling systems?
None of the above. * Ghosts are not a part of physics. * Electromagnetic fields in a static sense do not exist. Electromagnetic radiation does; it consists of a changingelectric field which causes a changing magnetic field which causes a changing electric field which causes . . . and so on forever. Electromagnetic radiation moves off at the speed of light ; it has different properties depending on how fast the fields are changing, including radio waves, microwaves and light.. * A microwave oven generates microwaves. Microwave radiation cannot "detect" itself. * Cooling systems are designed and built to cool. They can't detect anything, including microwaves.
Do electron holes literally move?
This is a very good question, that is not easy to answer. That is because a "hole" is a imaginary particle, a concept, with some special characteristics. Here you'll find the detailed answer:
http:en.wikipedia.org
In short you could say that the movement of a hole is the combined movement of lots of electrons, but that is meaningless if you don't understand the concept.
It's like a hole in the road. If you dig a hole next to it, using the rubble to fill it up, has your hole moved? Where it was, there is now no hole. But there is a hole nearby. Electrons in a semiconductor valence band behave like this. You can't get a current because the electrons are all packed neatly with nowhere to move. But if one is missing, there is a hole, and the electron next door can jump into it leaving a hole behind, so it looks like the hole moved.
Sample problems in stress and strain?
A cylindrical reactor consists of a cylinder and a head. The cylinder and the head have flanges and a gasket seal; the head is attached to the cylinder by a set of 8 three-quarter inch stainless steel bolts. There is a gasket between the two flanges and a Bourdon gauge attached to the cylindrical portion (not shown). The inside of the reactor is 18 inches in diameter.
On My Baby Girl DS game how do you get her to turn to the sound?
I wish i could help but i can a little bit just shake it at her face then move side to side
A pylon holds up the wires carrying electricity. If there were no pylons the wires would drag onto the floor and if you were to tread on them you would get electrocuted by the wires.
That greatly depends on the type of steel you are welding, but you should be safe with a CO2 Argon mix, otherwise known as Steel mix, it is good for mild to medium grade steel.
Can I put a sim card from one carrier into an unlocked phone from a different carrier?
Theoretically yes but you should make sure the unlocked phone you are transferring your SIM card into also supports the same cellular providers operating frequency. Its like this, every GSM cellular service provider operates in one or two of these possible frequencies 850/900/1800/1900 MHz. This will depends on the carrier and the country in which service provider operates, its usually 850/1900 in North America and 900/1800 in Europe and Asia. Most of the phones sold in the USA/Canada work in the North American frequency and not in other, so make sure your new unlocked phone works in the particular frequency for your provider.
No - just operated incorrectly. Several TV programs discussing findings regarding this subject reveal two [that I can recall] problem areas in the design and conctruction of the Titanic. 1. The bulkheads, which were supposed to form individual watertight compartments, should have gone much higher, in the hull, than they did. The lower upper edges of the bulkheads, as the ship began to sink by the bow, allowed the seawater to enter the first, then second, third, and so on compartments, thus causing the the ship to sink. 2. Metalurgic analysis of the metal hull plates revealed that the steel "receipe" was extremely poor, in that it was rendered very weak and brittle, resulting in the ice berg cutting a long gash through several compartments. Had the steel been like ours of today, the hull plates would not have failed, and there would not have been any flooding of any compartments, thus no sinking.

Do I Make copies face up or face down?
Assuming you're talking about using a photocopier - or a scanner... the information you want copied - is usually placed face down. The scanning/copying components are normally in the base of the equipment.
Can you reverse the polarity of AC and DC?
We have the capacity to reverse the polarity of a DC voltage, at least as regards what we apply it to. When we consider a DC motor, like, say, the ones in the little "robot wars" we see on TV, the motors can be run in reverse by reversing the polarity of the applied DC voltage. We normally consider AC as already reversing its polarity. It is, after all, AC, which is alternating current. The current alternates because the voltage alternates. We'll avoid any further discussion of the polarity of AC voltages here and leave it at that.
Answer
The problem, here, is that 'polarity' has several different meanings.
Polarity, in the sense of 'electric charge' cannot really be applied to a voltage (potential difference) although it can be to a potential (although the polarity is relative; it depends on the point of reference).
Polarity, in the sense of 'direction', can be applied to a voltage. For example, is the voltage acting clockwise or counter clockwise around a circuit?
Polarity, in the sense of 'connection', can be applied to a voltage. For example, it's important that the line conductor is connected to the centre terminal of an Edison lamp holder or to one or other of the slots in a receptacle (power socket).
Can you have a plan phone and use prepaid with it?
Yes. As long as you are out of your contract or willing to pay the cancellation fees - you can unlock your phone and bring to a prepaid network. Once you unlock your phone, you just need to purchase a SIM card.
I personally did this a few months ago, and switched to Straight Talk. I know there are other prepaid networks that can take unlocked phones as well.
A superhero (sometimes rendered super-hero or super hero) is a type of Character possessing "extraordinary or superhuman powers" and dedicated to protecting the public.
(wikipedia)
Lara croft does not have "extraordinary or superhuman powers" although she can fight very well so i'd say she's a hero, which is as good as a superhero, since they both save the world.
Steering wheel warning light comes on?
The steering wheel warning light will come on in a vehicle when a problem has been detected within the steering system. This can include low power steering fluid or incorrect pressure.
Free unlock codes for Motorola c168i?
I dont think you can get free unlock code for this model..but you can get affordable code from TheUnlockArena.com
How long do you charge a 9.6v rechargable battery pack for?
The charging time does not depend on the voltage of the battery. You have not supplied enough information to give a reasonable estimate. edit: Get a smart charger, and never have to worry about charge time again!
Why do the Amish not use electricity?
The Amish have no problem with electricity, but they worry about what electricity can bring to their homes, such as radio, television, and other things that may connect them with the people they consider "outsiders." They want to be as little connected with "outsiders" as possible. However, some Amish bishops allow a few families to have electric lighting.
What is the gold kt weight in a computer?
Gold weight is one thing, karat is the purity of the gold.
In old computers there was alot of gold in the contacts as gold is the best conductor of electricity. As computers evolved there tends to be less and less gold . Most computers today have little to none . Thus maybe a couple of dollars worth to nothing.
