Which statement is supported by this scenario? Jin is standing still and watching an archer on a horse
traveling away from a target. The archer is moving at a
speed of 4 m/s and shoots the arrow toward the target
with a speed of 17 m/s.
For Jin, the speed of the arrow is 21 m/s, and for the
archer, the speed of the arrow is 4 m/s.
For Jin, the speed of the arrow is 13 m/s, and for the
archer, the speed of the arrow is 17 m/s.
For both Jin and the archer, the speed of the arrow
is 21 m/s.
For both Jin and the archer, the speed of the arrow
is 17 m/s.

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
