Explain using the atomic particles what is happening when a wire heats up as current flows through it?

Electrical current is made up of protons and neutrons. Voltage itself doesn't do much, but when combined with amperage that's when things happen. Amperage is the force which makes the voltage flow. More amperage means more force, which means more friction on the molecular level. Friction causes heat which makes the wire warm.

How does recorded audio stay on an audio tape?
A magnetic field is created with varying intensity the current through a tape record head and either pulls or pushes the alignment of metal oxide particles either forward or backward with varying degrees of magnetic intensity. You can imagine this as the particles in the tape acting as little magnets each with their own degree of either positive or negative orientation. As a read head passes over the tape, the tape pushes and pulls the magnetic field in the read head and produces a small current. This is similar to current induction
When you listen to music do particles in air travel all the way from the stereo speaker to your ear?
No they do not. Sound moves in waves. | | | | | | | | | | | | | | | | | It is rather hard to explain. In the diagram above the lines are closer together in some places than others, these areas move along from left to right as shown below | | | | | | | | | | | | | | | | | | | | If you replace the lines with particles of air you can get a good idea of how sound waves move through the air. The air particles move for a bit when they get closer together but after the sound wave has passed they return to their original position, they don't move along with the wave.
Why does radio fuse blow on a chrysler sebring?
The fuse blows because the current through it exceeds the rated current limit of the fuse.
Where did most of the alpha particles fired at the foil go in the gold foil experiment?
Most of them went right through.
How do sound waves travel through media?
Sound waves travel through vibrations. If one particle starts vibrating it will pass on that movement to other particles that are close by. This means that sound travels quickly through solids as the particles are closely packed and readily pick up movement from their neighbours; it travels less quickly through liquids as the particles are close enough to pick up vibrations but not tightly packed like they are in solids; sound travels slowest through gases (weird, but true - even though we rely on gases to pass on the sounds we make in speech) because their particles are much further apart. If there are no particles - like in a vacuum such as you'd find in space - then sound can't travel at all!
What are the tiny particles that move through wires when a current flows?
electrons
Explain why sound travels quickest through a solid?
This is due to the particles and the density of the the object
The particles that move through a material to form an electic current are called?
Electrons
What is the continuous flow of electric charges through a material?
Yes, an electric current is the flow of charged particles.
What is the type of energy occurring when negative particles flow through a circuit?
Electric current
Electrically charged particles move through materials that are classified as electrical conductors?
Electrons. A current.
What is a temporary magnet caused by an electrical current?
A Electro Magnet, caused in theory by the alignment of the particles in the material duo to the current passing through it.
How do you explain to a kid what electricity has to do with magnetism?
You can explain the basic relationships:* An electrical current will be accompanied by a magnetic field. That is, it will act as a magnet. * If a conductor moves through a magnetic field (e.g., near a magnet), a current will flow through the conductor (if there is a closed circuit).
Explain how a general diode is used to change alternating current into direct current.?
The specific type of diode you are thinking of will only let current through in one direction.
What is the meaning of fuelcell?
it is a type of electro chemical cell that is able to fuel into electric current , it is able to do it through reaction between oxidized particles and electric current
How would you explain the process of abrasion?
Abrasion is the grinding and wearing of rock surfaces through mechanical action of other sand particles.
Explain why beta and gamma particles can easily enter your body?
Beta particles are very small and gamma rays are insubstantial so they can easily pass between or through the atoms of your skin and into your body.
