If the potential is zero at a point at infinity, find the value of the potential at the following distances from the center of the sphere: (a) 48.0 cm (b) 2ial at the following distances from the center of the sphere: (a) 48.0 cm (b) 24.0 cm  (c) 12.0 cm

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

To find the mass defect for uranium-238 several calculations must be made. which is the calculation that should be made first? assume atomic number for uranium-238 is 92. a. 92(1.0073) x 92(1.0087) = b. 92(1.0073) x 146(1.0087) = c. 146(1.0073) x 238(1.0087) = d. 238(1.0073) x 238(1.0087) =
