An inverted jar is lowered 10.4m below the surface of fresh water. what is the total pressure on the air in the jar?What fraction of the jar, originally full of air, is now filled with water?​

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
