Answer:
Y, X, Z, W
Explanation:
You know W is the most recent because it features the nucleus in the middle and the electron cloud which was shown in models after the others.
Answer:A
Explanation:
A positively charged glass rod attracts object x. So, object x must be negatively charged or uncharged.
This occurs because opposite charges attract each other or either object x is uncharged and a negative charge is induced in it as glass rod approach the object x.
So option A is correct
<span>Convection is a process of heat transfer between a surface and a moving fluid. It occurs when the air has a lower temperature than the body, and the body transfers heat through contact with the cold air around it. Air heating causes it to rise. The increase in temperature affects the convection process, since as the warm air rises, the cold air takes its place, thus completing its convection cycle.

Both have shallow atmospheres H2, He, and CH
They both have moons.
They're known as Near Twin Planets because they both have a greenish/ blue color.
There are two kinds of electrical charge.
We call them 'positive' and 'negative' ... I guess nobody ever thought of better names.
One basic law of electric charges is:
Two of the same kind of charge repel each other.
One of each kind of charge attract each other.
Electrons all carry a negative charge.
So two electrons carry the SAME kind of charge, and so repel each other.
