A voltaic cell consists of an au/au3+ electrode (e° = 1.50 v) and a cu/cu2+ electrode (e° = 0.34 v). calculate [au3+] if [cu2+] = 1.20 m and ecell = 1.13 v at 25°c.

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
