if the 1kg standard body an acceleration of 20.0° to the postive direction of an x axiis : a) what are the x and y compnonents of the net force acting on the body . b) what is the net force in unit-vector nation

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

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

An object has a weight of 500 on earth what is the mass of this object
