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.
Why does different samples of a solid ionic compound are made up of crystals that have approximately the same shape?
when ionic compounds form solids, they make a crystal lattice. This is built up so that the positive ions are nearest to the negative ions, forming a solid.
Large carbon molecules are built from smaller simpler molecules called?
The phenomena of formation of large carbon compounds by the addition of small molecules is called polymerization and the molecules are come under macromolecules as they possess molecular weight several to hundred thousands
What are compuonds withe the same cheimcial formule but different structure?
structural isomers: Such as glucose and fructose. Both chemical names of C6H1206, but structurally they are built differently.
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'.
Who built the first machine that produced charges by rubbing a rotating ball?
hauksbee
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
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.
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.
In a spreadsheet a built in formula is called?
In a spreadsheet a built-in formula is called a function.
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.
Describe how the movement of electrons between two objects with balanced charges could cause the buildup of electric charge in both objects-?
Electrons have a charge of minus one,and by moving them between objects, they attract charges, and hence they built up charges in them.
Is the battery negative ground on a Porsche?
Yes, unless it is a Porsche built in the 50s.
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.
Why do you need to hold the piece that plugs into your laptop in a certain way so it charges?
because it was the way that the laptop was built
Who built the tank and when it was built?
british called little willie
What was the first car built in 1885 called?
The car that Karl Benz built in 1885 was called Motorwagen.
