Charging by friction - this is useful for charging insulators. If you rub one material with another (say, a plastic ruler with a piece of paper towel), electrons have a tendency to be transferred from one material to the other. For example, rubbing glass with silk or saran wrap generally leaves the glass with a positive charge; rubbing PVC rod with fur generally gives the rod a negative charge.
Charging by conduction - useful for charging metals and other conductors. If a charged object touches a conductor, some charge will be transferred between the object and the conductor, charging the conductor with the same sign as the charge on the object.
Charging by induction - also useful for charging metals and other conductors. Again, a charged object is used, but this time it is only brought close to the conductor, and does not touch it. If the conductor is connected to ground (ground is basically anything neutral that can give up electrons to, or take electrons from, an object), electrons will either flow on to it or away from it. When the ground connection is removed , the conductor will have a charge opposite in sign to that of the charged object.

Compare the three methods of charging?
There must be electric current for something to be charged. When you are charging something, you will align the electrons towards a given direction. The aprtcle become charged once the electrons are aligned in a given direction.
What three concepts are the basis for object-oriented programming?
Classes, objects and methods are the three concepts for OOP programming.
Which of the three main methods of charging an object involves no touching?
Charging by induction.
When the object is charged by contact what kind of charge does the object have compared with that on the object giving the charged?
When an object is charged by contact, the object getting the charge has the same charge compared with that of the object giving the charge. so if the object giving the charge has a positive charge, so does the object getting the charge
What is true about an object pulled inward in an electric field does it have negative charge object has charge of different field object has neutral charge or object has a charge same field?
Negitive
What are the three ways heat energy moves?
a buildup of electrons on an object is called a blank charge
3 methods of charging an object?
There are three main ways of electrically charging an object:By frictionBy contactBy induction
When the total charge on an object is zero the object is electrically what?
The object with zero charge is electrically neutral.
What happens to an object with a positive charge and an object with a positive charge?
They attract.
What object has charge if it has positive charge?
That would apply to any object.
To say that electric charge quantized is to say that the charge on an object is?
Quantized charge means that the charge on an object exists in integer units of the charge of an electron, e.g. object charge = Ne, where N is an integer number..
How can an object have a neutral charge if part of the object has a positive and a negative charge?
If the positive and negative charges are equal, then the object has a 'net' neutral charge.
