Aplanet moves in an elliptical orbit around the sun. the mass of the sun is ms. the minimum and maximum distances of the planet from the sun are r1 and r2. using kepler's 3rd law and newton's law of universal gravitation, find the period of revolution p of the planet as it moves around the sun. assume that the mass of the planet is much smaller than the mass of the sun. use g as the gravitational constant

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
