A rabbit hops through a vegetable garden. He first hops 2 m south, then 4 m west, then 3 m south, and finally 1 m east. What distance did the rabbit travel? What is his displacement?

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
