Answer 1

Electrolysis helps in metallurgy.
it helps to purify metals
it helps to find the conductivity of a substance

Answer 2

Answer:

1224.5 Kg

Explanation:

Power = 2KW = 2000 W

Time = 1 min = 60 second

Now,

Power (In watt) = Work / Time (in seconds)

∴ 2000 = work / 60

∴ work = 120000 J

∴ mgh = 120000

∴ m = 120000 / (9.8 * 10)

∴ m = 1,224.49 KG
