What causes a pithball to move in an experiment involving a pithball electroscope?
electrons jump onto or off the neutral ball when a charged object comes close to it
What is the pH of vegetable broth?
6.9, close to neutral pH.
Is milk neutral an acid or a base?
milk is an acid (barely... It is very close to neutral)
What kind of radioactive elements is used for dating an object?
One with a half-life close to the age of the object
What is pH of rainfall water?
Should be close to neutral or 7 except acid rain.
What is a charging a neutral object by bringing it close to a charged object?
induction
What happens when a positive object is close to a neutral object?
Nothing.
What effect does a negative object have on a neutral object?
If the event horizon (space, in this case) of one of the items is breeched by the other and touch, the neutral object becomes negatively charged. If they never touch, they both remain in their present condition. The neutral object's condition will never affect the charge of the negatively charged object, whether they touch or do not touch. The negatively charged item's condition will never change, regardless of physical touch between the two items. ***************Contributed by Czar Acumen*******************
What method of charging wherein threre is no contact between a charge object and neutral object?
There is a very simple and easy way of charging a conductor without an actual contact. Rub a glass piece in silk and a static charge develops in the glass piece. Now bring this glass piece close to a metal ball grounded. This develops a charge in the ball. The opposite charge flows to like charges flow to the ground while the unlike charge remains.
When a negatively charged object approaches a neutral object what sort of charge is induced on the neutral object?
None. That said, most neutral objects we meet in everyday life are composed of positively and negatively charged objects which simply cancel out to give an overall neutral object. This is important because they can create Van der Waal forces, since the positive is a bit stronger than the negative in some areas very close to the object, and vice versa.
Three methods to charge an object?
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.

What are the two ways to transfer electrical charges?
Friction - charging something by rubbing it against another object Induction - charging something by coming close to charged object, but not touching Conduction - charging something by touching a charged object
What is the difference between charging by contact and charging by induction?
It normally requres two coils of wire placed close to each other. The AC field on one will induce an AC field in the other. More chargers of portable equipment are using this method. It requires no physical contact, so reduces problems of poor contacts and can make the item more water proof.
Is close the door a direct object?
No, "close the door" is a verb phrase, with "close" as the main verb and "the door" as the object of the verb. In this case, "the door" is the direct object of the verb.

bringing face very close to mirror water will forms on the mirror why give scientific reason ?
What object in space exerts force on another object that is close to it?
Every single object in space exerts a force on every single other object. They don't even have to be close.
