In a pith ball experiment, the two pith balls are at rest. the magnitude of the tension in each string is |t|=0.55n, and the angle between each string and a vertical line is θ=27.33∘. what are the values for the magnitudes of electrostatic force, fq, and the gravitational force, fg?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

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
