Electrostatics

Two different methods, either: 1) Faulty internal wiring is the most common cause. A live cable is somehow electrically connected to appliance. 2) Static build up, can be caused by internal mechanical movement. Note that the appliance may appear charged if a static shock is received, but the charge is not actually received from the appliance, but instead delivered to the appliance from the person.

I assuming you are meaning the potential difference of an electrical charge. Matter is made up of atoms, which contain protons and electrons. Protons have a positive charge, electrons have a negative charge. The 'separation' is that one side has a different ratio of protons/electron charge to that of the other side. The difference is measured in volts, and when connected together using conductive material will cause the radios to become more equal, this causes a current, which is measured in amps.

Speed is a scalar and velocity is a vector.

A scalar only has magnitude while a vector has magnitude and direction.

Example: If you are traveling north at 65 miles an hour your speed is 65 miles an hour, your velocity is 65 miles an hour north.

It gets a little more complicated. Speed = distance (a scalar)/time Velocity = Displacement (vector)/time

Example: If you run 5 miles in an hour left and then 5 miles in a hour right your speed is 10 miles/2 hours = 5 miles an hour. However, since you end up in the same exact location as where you started your displacement is zero making your velocity zero as well. Think of it this way; since velocity is a vector it requires a direction if i ended up exactly where I started I have no direction, thus velocity must be zero.

One more example to clarify: If you ran 6 miles right and 4 miles left in 2 hours, your speed will be 5 miles an hour (10/2=5) your velocity would be 1 mile an hour to the right, since displacement is 2 miles to the right (6 to right - 4 to left = 2 to right) and the time is 2 hours displacement/time = velocity; 2 to the right/2 = 1 mile to the right per hour.

Static electricity can occur when certain materials rub against each other, causing the transfer of electrons between the two surfaces. This transfer of electrons can build up a charge on the surfaces, resulting in static electricity. Common examples include when you walk on carpet and touch a metal object, or when you rub a balloon on your hair.

When lightening strikes a human, it will need to travel through the person. Depending on where is travels through the person greatly determines if the person survives the event. Crouching with your arms around your legs is considered a position which is most safe.

Electric potential is the amount of electric potential energy per unit charge at a certain point in an electric field. In the case of two oppositely charged plates, electric potential is the measure of the electric potential energy per unit charge experienced by a charge placed between the plates. It is measured in volts and is proportional to the strength of the electric field between the plates.

A technician can discharge static buildup by wearing an anti-static wrist strap connected to a grounded object or by touching a grounded metal surface before handling sensitive electronic components. This helps to prevent damage to the components from electrostatic discharge.

The resistance of a material is defined as:

R = r * l / A where

r (actually it is the Greek alphabet rho) is the specific resistance and is independent of shape, structure, etc, but is specific to the material only; l is the length and A is the area of cross section. Let R1 = r * (l1/A1) and after stretching it becomes R2 = r * (l2/A2) R2/R1 = (l2/l1)*(A1/A2) -------------------------- equation 1

If the wire has been stretched with no loss of material, the volume remains the same. Hence,

l1A1 = l2A2

which gives A1 = A2*(l2/l1).

given that (l2/l1) is 1.25, we get

A1/A2 = 1.25

Using this value in equation 1, we get

R2/R1 = 1.25 * 1.25 = 1.5625

Hence, the resistance of the wire increases by a factor of 1.5625.

Yes...all metals are will conduct electricity.

They are both dealing with electricity, so yes. 'static' electricity is mearely a categorization of electric phenomena. The best I've seen it dealt with is here: http://amasci.com/emotor/stmiscon.html#one

While "static" typically implies immobility or lack of change, static electricity actually involves the movement of electric charges on a surface or between materials. When certain materials rub against each other, electrons are transferred, leading to an accumulation of charge that can cause a spark or shock when discharged. So, despite the name, static electricity is not truly static in nature.

Transfer of charge by touching is known as charging by conduction. When a charged object touches a neutral object, electrons are transferred between the two objects until they reach equilibrium, resulting in both objects being charged.

Static electricity in airplanes can build up due to friction between the plane and the air. This buildup can cause sparks and potential interference with electronic equipment. To prevent this, airplanes are equipped with static discharge wicks or metallic strips to safely dissipate the static charge into the air.

Most types of waves are considered to have no mass. eg. Light has no mass, its really just a vibration of electromagnetic energy. If you have no mass, then their is no force to act upon the medium.

Electrons always move 4m a region of low potential 2 higher. While electrons move 4m negative 2 positive terminal they continuously gain energy as work is done on them by the positive terminal to attract them 2wards it. In this process an energy equal to the work done on the electrons ( by the positive terminal ) is gained by the electrons. That is y, as electrons cum closer to the positive terminal they hav high potential stored in them..The electrons, in order to attain this high potential flow 2wards the positive terminal of a battery wen connected in a circuit...

The wool would have a positive charge, while the comb is negative. This is because the comb will take excess electrons from the wool.

Each Coulomb of charge passing through a 6V battery gains 6 Joules of energy. This can be calculated using the formula Energy = Charge x Voltage. So, for every Coulomb of charge passing through a 6V battery, it receives 6 Joules of energy.

The force between two electrons is given by Coulomb's Law: ( F = \frac{k \cdot q_{1} \cdot q_{2}}{r^2} ). Given that the force is 5.0 N and the charges of electrons are equal ((q_{1} = q_{2} = -1.6 \times 10^{-19} , C)), and the constant (k = 8.99 \times 10^9 , N \cdot m^2/C^2), we can rearrange the formula to solve for the distance (r). Solving for (r), the distance between the two electrons is approximately (1.1 \times 10^{-10} , m).

In conductors, charges repel each other and redistribute themselves to the surface of the conductor due to electrostatic forces. This redistribution leads to a state of equilibrium where the electric field inside the conductor is zero. As a result, excess charges accumulate on the surface to minimize the repulsion between them.

Alternating charged current arrives at one terminal on the cap. The load to ground is connected at the other terminal of the cap. Actually 'alternating' can be a confusing electrical term to some folks. Think of the charged current as a wave that delivers this positive current from the bottom to the top of the wave and retreats or falls off at the bottom of the other side of the wave. This condition is caused from the rotating action of the rotor turning inside the stator fields in a generator. The ground through the load is attracted to the positively charged electrons at the barrier of the cap at the top of the wave from the generator. Now. Think charge separation on the ground side. As the electrons become excited on the ground side of the cap at the barrier across from the positive charge (attraction), a vacancy of non-charged electrons has occurred downstream at ground. When the positive charge and current falls at the bottom of the wave from the generator side, the excited electrons at the barrier of the cap on the ground side are now positive (charge separation) and move to power the load and fill the vacancy to ground. This is also the reason for the delay of current and charge moving through a cap to ground. A larger barrier equals a longer delay (faud rating). Nothing but magnetic field attraction between electrons has happened at the cap barrier. This is why a DC current cannot move through a cap. It has no wave. If we pulse the DC, we can get it to move through the cap, but at a lower efficiency than AC.

The net force on a positive charge q3 would be zero when it is placed between q1 and q2 along the line connecting them. This occurs at a point closer to q1 than q2, at a distance x from q1 greater than 0 and less than 1.0m.

Electrostatic potential is a scalar quantity. It represents the potential energy per unit charge at a given point in an electric field.

To find the direction of a vector, you can use the formula: θ = tan^(-1) (y/x), where θ is the angle of the vector with the positive x-axis, and (x, y) are the components of the vector along the x and y axes, respectively.

The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.

Quantization of charge means that the electric charge carried by an object is always a multiple of the elementary charge (the charge of a single proton or electron). This concept arises from the discrete nature of charge, which is one of the fundamental properties of matter.
