Electroplating Zinc onto Copper: Calculating Time Needed

AI Thread Summary
To calculate the time needed to electroplate zinc onto a copper sheet, one must first determine the volume of zinc required for a thickness of 140 micrometers on both sides of the sheet. Given the density of zinc and the charge of divalent zinc ions, the total charge can be calculated using Faraday's laws of electrolysis. The current of 1.40 A will then be used to find the time required for the electroplating process. Understanding the formulas for electroplating and the relationship between charge, current, and time is crucial for solving this problem. Proper application of these principles will lead to the desired thickness of zinc on the copper sheet.

Wow. Can anyone please tell me how to approach this problem?

For a science experiment you need to electroplate zinc onto both sides of a very thin, 1.00 1.00 copper sheet. You want the zinc thickness to be 140 , and you know that the charge carriers in the ionic solution are divalent (charge ) zinc ions. The density of zinc is 7140 .

If the electroplating apparatus operates at 1.40 , how long will it take the zinc to reach the desired thickness?

Why don't you show us how far you got? You know, that thing in the template which somehow is missing from your message.
 


that's the thing. Mastering Physics homework assignments give problems that are not covered in lecture or in the book. That is why I don't even know how to approach this problem, or what formula to use :T
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
