Two capacitors, C1 = 28.0 µF and C2 = 41.0 µF, are connected in series, and a 18.0-V battery is connected across them.
(a) Find the equivalent capacitance, and the total energy stored in this equivalent capacitor.
(b) Find the energy stored in each individual capacitor.
Show that the sum of these two energies is the same as the energy found in part (a). Will this equality always be true, or does it depend on the number of capacitors and their capacitance's?
(c) If the same capacitors were connected in parallel, what potential difference would be required across them so that the combination stores the same energy as in part (a)?
A train 400m long is moving on a straight track with a speed of 84.30km/h. The engineer applies the brakes at the crossing and later the last car passes crossing with the speed of 17.7 km/h. suppose constant acceleration; conclude how long the tra..
