Homework Statement So I am doing a mini-lab and I measured the temperature of water before heating it up and after. I determined delta T or the temperature gain to be https://www.physicsforums.com/file:///C:/Users/BADGER~1/AppData/Local/Temp/msohtmlclip1/07/clip_image002.gif...

The emf was right. It was 0.37 V.

Can anyone give me assistance on 4-13 on how to start. I've looked in my book several times.

Did I do 3 and 1 correctly?

It's the units for flux to use

magnetic flux.

In the book it uses m^2T

I guess I don't understand where you are going with this.

magnetic flux.

So it should be 0.26 Webers? Or are you saying I need to convert that to webeters to use it in the emf equation?

What do you mean second Question? . From homework 8, I am looking at problem 2.

gracy, I am confused because the problem says 0.04T to 0.3 T. What do you mean the answer should be in Webers?

Homework Statement I am stuck on 2 and 3. I attached all the problems and variable and unknownsHomework Equations I attached my work for 1, 2, and 3. I'm not sure if it is right though. [/B]The Attempt at a Solution Can someone check my work for problems 1, 2, 3 and 4? The equations...

What are some reasonable assumptions and values for a cross-sectional radius of a ring? Is 0.1cm for r and what is the L for?

Homework Statement Estimate the resistance of a gold (wedding-type) ring. State clearly all assumptions, and introduce any equations you use. your solution should also include a brief summary of how you approached and solved the problem. Helpful tip: You will have to make certain...
