One capacitor is charged until its stored energy is 4.5 j. a second uncharged capacitor is then connected to it in parallel.
(a) if the charge distributes equally, what is now the total energy stored in the electric fields?
(b) where did the excess energy go?
a) kinetic energy of the electrons
b) thermal energy in the wire
c) potential energy is stored in the current
d) potential energy is stored in the magnetic field
the correct answer is a. lever
a. heat. this is because, obviously, it gives off light which us see and heat because after a while, the light bulb starts to heat up and produce heat.
1.) the objects have the same temperature
this is the answer because thermal equilibrium is when two substances touch and the temperature becomes the same.
the acceleration is negative when the speed starts to decrease, which is confirmed by the second situation: b) the velocity of a car reduced from 50km/hr over one minute.
