Electrostatics

Law of inertia states that "In the absence of an external resultant force, a body at rest will remain at rest and a body in motion will remain in uniform motion in a straight line".

Mathematically:

if ΣF = 0

then a = 0

If it's DC voltage, the relationship between current, resistance and voltage is defined by Ohm's Law.

V = I / R

A little manipulation shows that I = V * R. If The voltage and/or resistance varies with time, an easy way to describe it would be thus:

I(t) = V(t) * R(t)

Where I(t), V(t) and R(t) are all functions of time.

Suppose object A is propelled in the upward direction from height h_0 with an instantaneous upward velocity at time t=0 of v_0, and that object B is dropped from height h_1 with an instantaneous velocity at time t=0 of 0. Height increases in the upward direction. We assume acceleration due to gravity of 9.8m/s^2 in the downward direction. Recall that velocity is the first derivative of position, and that acceleration is the second derivative. After a bit of simplification, we can express object A's height at time t as h_A(t) = h_0 + tv_0 - 9.8t^2/2

and object B's height at time t as h_B(t) = h_1 - 9.8t^2/2 we now wish to solve the equation h_A(t) = h_B(t) in terms of t. Writing it out: h_0 + tv_0 - 9.8t^2/2 = h_1 - 9.8t^2/2

We note as a matter of interest that the acceleration terms cancel, which is to be expected as the objects are (assumed to be) in a uniform gravitational field. Technically speaking, we can find an accelerating frame of reference in which gravity plays no part. So our equation is: h_0 + tv_0 = h_1

t = (h_1 - h_0) / v_0. All of this is of course in SI units (seconds, metres, metres-per-second).

In other words, the time taken is the distance between the two objects divided by the speed at which object A is launched vertically.

A lens can be used to concentrate light. A group of mirrors aimed at the same location as they track the Sun would increase its' intensity. Upto 7000 degrees.

Coulomb's Law states that the magnitude of the electrostatic force between two point electric charges is directly proportional to the product of the magnitudes of each charge and inversely proportional to the square of the distance between the charges. A link is provided to the Wikipedia article.

It doesn't The 'Ozone Layer' does, this is a layer of 03(subscript 3) which is above the troposphere and works by maintaining an equilibrium with its conversion to 02(subscript 2) and by deflecting ultra-violet radiation and filtering out short-wave radiation.

Cross the beams.

It takes a battery that delivers the voltage that the bulb is designed for,

at a current of (10/bulb voltage) amperes for a reasonable length of time.

No.

What does "the following"mean ?

It is because electrostatics mean the charges which are static and not in motion.

A continuous unbroken path of electrons is a closed circuit. If there is an opening, then it is an open circuit.

A spark lighter is a tool used to ignite flammable gas appliances such as bunsen burners, welding torches, and gas grills. A spark lighter produces a spark having sufficient heat to ignite flammable gas vapor when a mechanical action causes a piece of flint to rub against a hard and rough metal surface. There are also solar spark lighters available which consist of a parabolic mirror that focuses sunlight on a flammable material at the focal point of the parabola. The heat at the focal point can reach several hundred degrees Fahrenheit, more than enough for lighting a cooking fire, etc.

The basic use of a Van de Graaf generator is to separate electric charges and build them up, frequently for demonstration purposes. A "big" version can be used to provide a burst of energy for generating X-rays, or for accelerating electrons or protons. The accelerated charges find some practical applications as well as some uses in scientific investigations.

It's an electrostatic generator, and it will create a considerable difference of potential. Use the links below to read more about it and what we use it for.

actually these are oxidized minerals found in hard water you either need a water softener or a salting system

Bigger the size more the charge could be derived but no way the potential difference get changed

the log rollers are lumberjacks

Alternating voltage is the E.M.F. and is one whose magnitude whose magnitude changes with time and direction reverses periodically.

The instantaneous value is given by

E=Eo sin w t, where,E=value of alternating voltage at time t

Eo = maximum value of alternating voltage(amplitude)

w=angular frequency of supply.

Most often than not we come across bodies undergoing more than one kind of motion simultaneously. Take a wheel of a moving car, for example. It is rotating about the axle and is also undergoing translatory motion. If we were to trace the path of a point on this wheel, it could give us information on the different motions superimposed on that point and the resultant of those motions. The pattern traced out by a point undergoing two or more kinds of motions is termed its Lissajous Pattern.

It is electricity that does not include rapid movement of the electrons, i.e. electric current. Static electricity refers to steady gathering of positive and negative charges in two nearby bodies or in opposite zones of a sole body. The study of causes and effects of this is called Electrostatics.

They are good at not transferring the electrons from the wires to their atoms. They dont pass them on because their atoms are stable and don't need any.

The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.

You can't fix it if it's dead you could only buy a new battery. To tita and my nabors zunilda and Natalie oh and evelise and burdo
