yes, because usually metals are positively charged and positive repells positive

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 takes on a negative charge also, the charge transfers to the pith ball from the strip

What best describes rutherford's model of the atom?
An example would be..Like a huge stadium with a positively charged marble at the center. Another example is..A small ball within a large shell containing empty space.
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.

3.0 x 10^4
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.
Is a past ball an error?
Yes, if the ball is pitched in a location where the catcher has a reasonable chance of stopping the ball, that is a passed ball and the error is charged to the catcher. If the ball is pitched in a location where the catcher does NOT have a reasonable chance of stopping the ball, that is a wild pitch and the error is charged to the pitcher. Actually, a passed ball is NOT charged as an error against the catcher. It's simply charged as a passed ball. Not terribly logical, I agree, but that's the rule.
