The following equations represent the four parts (a, b, c, and d) of a cyclic process with a gas. the gas does not obey the ideal gas law. w is the work done by the system on the environment and consequently q−w=δuint. w=(3.0×105n/m2)(0.020m3−0.010m3)+0+ (1.0×105n/m2)(0.010m3−0.020m3)+0 δuint=(3/2)(1.0mole)(8.3j/mole⋅k)[( 700k−360k)+(480k−700k)+(240k−480k)+ (360k−240k)] q=qa+qb+qc+qd

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

Acaterpillar tries to climb straight up a wall a meter high, but for every 2 cm up it climbs, it slides down 1 cm. eventually, it reaches the top. when it reaches the top, it does not pull itself over so it will slide down 1 cm. what is the total displacement traveled?
