The correct answer is <span>The car has both potential and kinetic energy, and it is moving at 24.6 m/s.</span>
Parallel has more than one circuit or form of energy
series has only one form of energy circuit
The answer is c you got to look for answers that make sense
The angle of refraction would be further less
If one of two interacting charges is doubled, the force between the charges will double.
Explanation:
The force between two charges is given by Coulomb's law

K=constant= 9 x 10⁹ N m²/C²
q1= charge on first particle
q2= charge on second particle
r= distance between the two charges
Now if the first charge is doubled,
we get 
F'= 2 F
Thus the force gets doubled.
