How does a lightning bolt form?
Lightning is caused by electric charges releasing energy. When the denser (positive charges) go to the top of the cloud, the less dense (negative charges) go to the bottom. This creates an electric imbalance of charges. In the ground, the negative charges are pushed away because the positive charges are attracted to the negative charges at the bottom of the cloud. If an object is in the way the lightning does what it has to to get to the ground, so it will get there faster. When the lightning is discharged you only glimpse it for a second until it disappears. It can travel 75 m/sec, so even though it creates light it is a release of energy so it doesn't travel at the speed of light.By Brian Hanglightning is not necessarily formed but is just a large build up of static electricity between a point on the ground and the storm cloud. Its when these plus and minus charges come together to form a lightning strike.Lightning is basically static electricity between the cloud and the ground. The cloud has too much of one charge (normally negative), while the ground has too much of the opposite charge (normally positive). The lightning bolt is the name of the electrical discharge between the two objects. It can also be between cloud-tree, cloud-car, or even (ouch!) cloud-human.Electricity in the air.
How does an ionic bond hold molecules together?
Ionic bond is due to the electromagnetic force attracting particles (ions in chemical terms) with charges of opposite sign. The ionic bond is the stronger bond that is present in chemistry after covalent bond. It is sufficient to consider the fact that a simple calculation of the electrostatic energy related to two atoms carrying a point charges of +/- 3 atomic units (that is +/- 4.8 10-20 C) at a distance of 1 nm gives a bond energy of 2.1 10-20 J, that corresponds to about 12.54 kJ/mole: a quite substantial energy for two so small charges. This energy critically depends on distance and, in case of distributed charges, on the bond geometry. An example of material that is built by ionic bonds is table salt, essentially a set of NaCl dispersed micro-crystals, where each crystal is constructed by the ionic attraction among Na+ and Cl- ions. The bond with which antibodies attaches to their specific antigens carrying out their role in human immunity system is frequently dominated by a ionic component.
How are polymers built and broken down?
The breaking down of some complex molecules, such as polymers, occurs through a process known as hydrolysis.Hydrolysis takes place in the presence of water containing an acid or a base as catalyst. The water causes polymers to breakdown to monomers. Hydrolysis reactions break bonds and release energy.
Why are atoms said to be electricly neutral?
Atoms are built form 3 types of particles Electrons (which are electrically negative) Neutrons (which are electrically neutral) Protons (which are electrically positive) Nature likes things to be balanced so when atoms are put together, nature makes sure that the number of Electron the atom has is matched by the number of Protons. This makes all atoms electrically neutral. However, when atoms react with each other chemically, they can share or swap electrons with each other which means that they are no longer electrically neutral (in this state they are called "ions"). Nature therefore requires that the stuff they have made (called a compound) when joining together is, overall electrically neutral and bonds them together so that this is achieved. This is why chemical compounds exist and are stable.
What is an eletron?
An electron is a sub-atomic particle which has a negative charge. Electrons have no known structure, and they have negligible mass. Current electron theory states that electrons move in random patterns, orbiting the centre of the atom (protons, neutrons) in a 'cloud'.
What is the Electric charge that has built up in one place referred to as?
The electric charge that has built up in one place is referred to as static electricity.
Can buyer of automobile part keep original part?
O f course you can. If the part you keep can be renewed or re built you have given up the trade in price but feel free to keep it. These trade in prices are called "core" charges. Batteries, alternators, starters an much more have core charges. Don
In a spreadsheet a built in formula is called?
In a spreadsheet a built-in formula is called a function.
What are the makes of vehicles with negative ground system?
Most all vehicles built today have a negative ground system, and have had for decades.
How does a 2007 cub cadet charge its battery?
With the built in stator or rectifier that charges the battery. It is under the flywheel.
Why capacitor charges exponentially why not linear?
because as the capacitor starts charging,the charges which are already built on capacitor opposes the further flow of charges. hence the process gets slow. thats we get sharp curve initially which gets flat further.
Describe how the movement of electrons between two objects with balanced charges could cause the buildup of electric charge in both objects-?
When electrons move from one object to another, they can cause an imbalance in the charge distribution of those objects. This can create areas of excess positive and negative charges on the objects, leading to the buildup of electric charge. The movement of electrons helps to create an electric field that can generate more charge separation between the objects.
Is the battery negative ground on a Porsche?
Yes, unless it is a Porsche built in the 50s.
Who built the tank and when it was built?
british called little willie
What does A built-in calculation such as SUM or AVERAGE called?
That's called a built-in function; or often simply a "function".
What was the first car built in 1885 called?
The car that Karl Benz built in 1885 was called Motorwagen.
How is static electricity differes from current electricity?
Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects. Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.
