The total capacitance of two 15uF capacitors connected in parallel is <em>30 μF</em> .
Kinetic energy is the energy possessed by a body while in motion. It is calculated by 1/2mv², where m is the mass of the body and v is the velocity.
Therefore, kinetic energy is dependent on both mass of the body and the velocity. An increase in mass increases the kinetic energy, an increase in velocity also increases kinetic energy of the body. Thus, doubling the mass and doubling the velocity will both increase the kinetic energy of the body.
The circuit is no longer closed.
I think its all four of them could be wrong but try all four !!!!!!
