Ответ:
Time required to deposit an even layer of gold with given thickness is
sec.
Explanation:
The given data is as follows.
Surface area = 49.8
,
Density of gold = 19.3
,
Current = 3.15 A, thickness of gold layer =![1.2 \times 10^{-3} cm](/tpl/images/0603/4820/eeacd.png)
It is known that relation between volume, area and thickness is as follows.
V = Surface area × Thickness
=![49.8 \times 1.2 \times 10^{-3} cm](/tpl/images/0603/4820/f32fd.png)
= 0.05988![cm^{3}](/tpl/images/0603/4820/61c31.png)
Therefore, we will calculate the time required to deposit an even layer of gold with given thickness is calculated as follows.
=
sec
Thus, we can conclude that time required to deposit an even layer of gold with given thickness is
sec.
