Consider an electrochemical cell in which you are plating a 10cm×12cm rectangular container by submerging it up to a height of 15cm in a solution of zinc. If the wires supplying power to your cell are rated to handle a maximum current of 0.5A, what is the minimum amount of time necessary to plate a 0.1mm thick layer onto the container? What is the current density during this plating process? Take the density of zinc to be rhoZn = 7.14 g cm3

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
