Answer:
During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. In order for the neutral sphere to become negative, it must gain electrons from the negatively charged rod. 3.
Explanation: For solid or cold objects, (like ice), the particles are close together and not moving. For liquids, (like water), the particles are moving freely and limited energy depending on if it is warm or not. For gas, the particles are way spread out, and moving fast.
Yes. They are called compound machines because two or more simple machines were combined to create it.
I cannot fully remember but the charge of a compound always has to be the same. However, I believe that the sign of the Y2 means that it is positive 2.
so in my opinion it is in between b and c. use your best judgment.
Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. These are electronegative elements with high ionization energies. They are non-lustrous, brittle and poor conductors of heat and electricity (except graphite).
