Explanation:
The particle will be at rest when its velocity 
is equal to zero. Recall that the velocity is simply the derivative of the position 
with respect to time:
Since 
then
Solving for t, we find that the particle will be at rest at
The power source its getting usually determines its voltage.
Solids: definite shape, definite volume
Because they are stiff and the molecules don't move around, they vibrate quickly.
Liquids: indefinite shape, definite volume
Because the shape or "fixed" area of liquids won't stay the same.
Gases: indefinite shape, indefinite volume
Because you've probably noticed, gases are set more freely, allowing molecules to move more freely than in solids and liquids.
x) Hope I helped! Which do you think it is?
If the answer is not C D then is A bc of the way it crosses over
