Electrostatics

Electric current produces magnetic fields around the conductor through which it flows, according to Ampère's law. Additionally, electric current also generates heat due to the resistance of the material through which it passes.

To conduct an electric signal from one point to another.

Near the charged object, there is a high charge, near the uncharged object a low charge. As you bring them together the gradient between the two gets steeper and steeper until it is strong enough to pull electrons away from the atoms in the air, ionizing it.

The ionized air conducts electricity better, making the gradient steeper still, and a chain reaction occurs. The energy stored is released in a sudden discharge, causing the heat, light and sound of the spark.

Lightning follows the same principle.

Depending on the direction of the magnetic field and the charge on the particle, the charge would move in a circular fashion either clockwise or anticlockwise depending on the circumstance. Using the right hand palm (push) rule, find the direction of the force (palm) and the charge continues on that path in a circular motion. If the particle leaves the field, it continues in that direction traveling in a straight line unless under other influences.

For most cmpds of the main group elements the lone pairs are of equal importance as bond pairs in determining structure hence the basis of VSEPR theory. The lone pairs are said to be stereochemically active. But for some higher-coordination main-group cmpds the lone pair becomes stereochemically inactive. For example, the [SeCl6]2-, [SeBr6]2-, [TeCl6]2-, and [TeBr6]2- ions all have regular octahedral structures in the solid state. But According to VSEPR these AX6E ions should not have a regular octahedral structure.

For transition metal cmplxs and organometallic cmpds the d e-s are completely stereochemically inactive: d AOs point between the ligands (e.g., oct [M(H2O)6]^n+ ions) or are involved in π bonding. Cr(CO)6 (octahedral), Fe(CO)5 (trigonal bipyramidal), Ni(CO)4 (tetrahedral), but all have 18 e-s: geometry dictated by ligands. ;)

Static electricity is the buildup of electric charge on the surface of an object. This charge can be generated by friction, contact, or induction, causing objects to attract or repel each other. When the charge is discharged, it can create a spark or shock.

Dryer sheets contain a thin layer of lubricant that gets transferred onto the fabric during the drying process. This lubricant reduces the static electricity that can cause clothes to stick together. Additionally, dryer sheets often have a coating of fabric softeners that further reduces static cling.

This process is known as electrostatic induction. It occurs when the electric field of an object causes the redistribution of charges in another nearby object, leading to the movement of electrons within that object. This results in one part of the object becoming positively charged and another part becoming negatively charged.

1. Rubbing a balloon on your hair creates an electrostatic force that causes the balloon to stick to objects.
2. Lightning is an example of the electrostatic force between clouds and the ground that results in a discharge of electricity.
3. Static cling occurs when clothes come out of the dryer with an electrostatic charge, causing them to stick together.

The movement of static electricity into an object is called "electrification" or "charging." This occurs when the excess charge is transferred from one object to another due to the presence of an electric field.

Any metallic material will conduct static electricity.

A Van de Graaff generator is an electrostatic generator which builds up an enormous positive charge on the outer surface of its principal dome. The negative of the circuit is provided by a smaller secondary dome or sphere. Since, it involves electrostatic charge the domes are kept spherical and smooth, as any unevenness or sharp edges would cause a drastic difference in the charge per unit area between the point of unevenness and the rest of the surface. At such high potentials this difference in charge per unit area can be harmful to the material of sphere, the circuit and the surroundings (as it may cause an enormous charge leakage leading to ionization of the surrounding air).

As I have no lemon juice or vinegar the easiest way I can think of to answer this question is for you to use an ohm meter and measure the resistance of each substance for conductivity. The lower the resistance the better the conductor. Poor a little in a bowl and put the two probes from the ohm meter into the liquid, turn the dial on the meter in the ohms area from one extreme to the other until you see the needle stop between the bars. Note the setting on the dial and the position of the needle. These will give you the resistance when added together (for example if your dial is on the .1 scale then you need to multiply the needle reading by .1 to get the ohms). Test each liquid's resistance and write down the ohms for each, the lowest ohms is the most conductive.

Rubbing wool against plastic doesn't actually "create" static electricity. However, rubbing wool and plastic together does increase the surface area of the two materials that are coming into contact. When this happens electrons are exchanged between the two surfaces creating an imbalance. It is this imbalance of electrons that we see as static electricity.

Static electricity is used in a photocopier to attract toner particles onto the paper that has been charged with the opposite charge. This creates an image on the paper which can then be fused permanently using heat. Static electricity helps in transferring the toner effectively onto the paper during the copying process.

Ancient explanations for static electricity often involved theories related to the imbalance of elemental forces or the presence of invisible fluids in the body. For example, in Ancient Greece, it was believed that static electricity was caused by an excess of the element fire or the accumulation of "electric" fluid in certain materials. These explanations were rooted in philosophical and metaphysical concepts rather than scientific principles.

To charge two 12 volt batteries in series you'd need a 24 volt charger. That's the pat answer. You need to overcome the total voltage of the series batteries (12 V + 12 V = 24 V) to drive electrons "back into" the batteries to restore the charge. It may work better to use a 12 volt charger and just disconnect the link between the batteries and charge them in parallel, but the setup may not support separating the batteries that way. You do have the option of charging them one at a time without disconnecting anything using that 12 volt charger we mentioned. Clip the charger across one battery, charge it up, then repeat with the other battery.

The two basic choices are getting an appropriate 24 volt charger or doing a bit of disconnecting and reconnecting so that the batteries can be charged in parallel with a 12 volt charger, which is a much more commonly available and less expensive charger.

That's excellent advice from Quirkeyquantummechanic and well said I might add. I'm in Australia and use 2X12 volt batteries to run my 24 volt Motorguide Trolling motor.

You can make disconnecting or reconnecting a lot easier when charging your 2x12volt batteries, needed to be run in series to produce 24 volts, by connecting an Anderson plug to suit. Connect the Anderson plug in a handy position into the short lead that goes from the positive post of battery1 - to the negative post of battery 2 - I.E. the lead that enables the batteries to run in series. Then simply add an isolator switch and turn the two batteries off before charging each one singularly with your 12 volt charger. Regards.

There are 14 types of Bravais lattices in crystallography, not 7. The packing fraction of a crystal is the ratio of the volume occupied by atoms or ions in a unit cell to the total volume of the unit cell. It varies depending on the type of crystal structure and can range from about 0.52 for simple cubic to about 0.74 for close-packed structures like face-centered cubic.

The two types of mechanical energy are kinetic energy, which is associated with the motion of an object, and potential energy, which is associated with the position or configuration of an object.

No , because velocity is a vector quantity and it needs direction.

Take measurements of resistances of various lengths of a wire of constant diameter. Make a graph of resistance against length / cross-sectional area of wire. The gradient of the straight line section will be equal to the resistivity of the wire.

It depends on size and regulatory "red tape". One wind power proposal in the Eastern US has been stalled for more than 15 years due to regulatory blocks and court battles. No doubt solar projects in the Western US face similar problems.
