What do you mean when you say "this" graph ? I don't see any graph.
First of all, I'm sure you don't have a "velocity versus time" graph. You may have a "speed versus time" graph, that doesn't show any information about the direction of the motion.
As you look at your graph ... a feat that's impossible for me ...
-- If the line is horizontal, then speed is not changing. If the direction of motion is also not changing, then there is zero acceleration. Sadly, the graph most likely doesn't carry any information about the direction. It's possible that the speed is constant but the direction is changing. Then acceleration isn't zero, but you can't tell that from the graph.
-- If the line is proceeding upward from left to right, whether it's straight or curving, then there is positive acceleration.
-- If the line is proceeding downward from left to right, whether it's straight or curving, then there is negative acceleration, or what some people might call "positive deceleration".
<span>The total
energy stored is the sum of the energy stored in the capacitors. If the
capacitors are series connected
capacitors, then the charging current is the same for both capacitors. This
means that each capacitor stores the same energy and the stored energy is two
times the energy of any of the capacitors.</span>
C it is the energy required to break existing chemical bonds, it is the amount of energy that a reaction requires in order for the reactants to successfully collide and react
