An electrically neutral object can be attracted by a positively charged object because?
A neutral pith ball is still "charged", it just doesn't display excessively charged behavior. Since it is neutral, having nearly equal positive and negative charge, the proximity of the positively charged pith ball still attracts the negative charge present in the ball, inducing polarization moving the ball closer to the positively charged one. Once they make contact, the conductibility of the pith ball quickly accepts excess charge from the other, creating a like charge repulsion.
When a metal ball is charged by induction using a negatively charged plastic rod what is the sign on the charge acquired by the ball?
There exists and answer to this problem if you state the following: After the ball has been in presence of the negatively charged rod, the metal ball is either grounded or discharged by another conductor leaving the original metal ball with a positive charge, hence the name charging by induction.
If a negatively charged polyethylene strip touches a neutral pith ball what charge will it have?
The pith ball will have a negative charge after touching the negatively charged polyethylene strip. This is because electrons are transferred from the strip to the pith ball, leaving the pith ball with a net negative charge.
How an atom works?
An atomizer works by first squeezing the ball on the top. The change of pressure in the bottle allows the contents to come to the top of a tube. When the air in the ball is released, the scent at the top of the tube is sprayed.
What is the chemical reactivity for copper?
Copper is a moderately reactive metal. It can react with oxygen to form copper oxide. It can also react with acids to form copper salts and hydrogen gas. Its reactivity can be increased in the presence of certain chemicals or conditions.
When the vinyl is rubbed with wool the electrons transferred to the vinyl. what kind of charge is on the pith ball when the charged vinyl repels it?
When the vinyl is rubbed with wool, it gains electrons and becomes negatively charged. The pith ball, which is initially neutral, will have its electrons repelled by the negatively charged vinyl, causing the pith ball to become positively charged due to the lack of electrons. As a result, the negatively charged vinyl repels the positively charged pith ball.
Which scientist described a positively charged ball with electrons embedded throughout it?
This scientist was Ernest Rutherford.
How can a positively charged ball be used to electrify two other balls?
By bringing a charged ball into contact with two others, the charges will equalize across all three balls. Electrons will stream off the two previously uncharged balls (assuming they were), and will reduce the positive charge on the first ball. This will leave the other balls positively charged. All three balls will be charged to some extent, and, though there will be differences on the charges on the balls, there should be no difference in voltage between the balls. Bringing them back into contact will not (should not) result in any more charge movement.

A charged object is brought near a metal ball that is mounted on a rubber sheet. If the metal ball acquired a negative charge after it was grounded momentarily what must be the charge of the object th?
If the metal ball acquired a negative charge after being grounded, the charged object must be positively charged. When grounded, the metal ball gained electrons which caused it to become negatively charged. This would only occur if the charged object had an excess of positive charge to transfer to the metal ball.
How is the pith-ball charged when it is repelled by glass rod?
When the glass rod is rubbed with a cloth, it acquires a positive charge by gaining electrons. When the charged glass rod is brought close to the pith ball, the negative charges in the pith ball are repelled, causing the pith ball to become positively charged by induction.

What best describes rutherford's model of the atom?
Rutherford's model of the atom proposed that atoms have a small, dense, positively charged nucleus at the center, surrounded by negatively charged electrons. This model suggested that electrons orbit the nucleus similar to planets orbiting the sun, but it could not explain the stability of atoms or the distribution of electron energies.
Why does a ping-pong ball attract then repel on a plastic rod?
A ping-pong ball attracts to a plastic rod due to static electricity. When the plastic rod is rubbed with a cloth, it becomes negatively charged, while the ping-pong ball can become positively charged through contact or induction. The attraction occurs because opposite charges attract. Once the ball is close enough, it can become negatively charged as well, leading to repulsion since like charges repel each other.
What would happen if a ball purely made of positively charged ions is made what would the effects be a massive lightning storm or an explosion?
It would be excessively hard to make a ball of appreciable size purely of positively charged ions as the repulsion force would be astronomical. If indeed enough energy is input to make this ball, as soon as the energy keeping it together is taken away, the ions of the ball will instantly experience enormous repulsion forces and fly apart. As to what that will look like, it's up to anyone's imagination. An "explosive" effect will probably occur but it's not really known.
What scientist made a billboard pool ball model?
Ernest Rutherford, a pioneering physicist, is known for creating the billiard ball model to describe the structure of the atom. This model featured a dense, positively-charged nucleus at the center with negatively-charged electrons orbiting around it, much like how billiard balls move around a pool table.
