Three parallel plate capacitors have the same dimensions. The area of each capacitor is A=250 cm? and they are filled with dielectrics of the same thickness d=25 µm but with different dielectric constants: K;=30, K2=50 and Ks=90, respectively. They are attached to the 12 V battery as shown in the drawing below. Find energy stored in capacitors 1 and 2. 12V C1,K1 C2, K2 C3,K3

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
