The diagram represents a snapshot in time of a wave traveling through a slinky. Four locations along the slinky are labeled with a letter. Indicate the direction of vibration of the slinky coils at these locations.

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
