The findings of henri becquerel and the curies to discredit what notion held for a very long time? that matter can never be created or destroyed. matter is made up of any smaller parts. matter is radioactive and decays over time. that matter is indivisible and indestructible.

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
