Inner conductor radius = 1cm outer conductor radius = 10cm region between conductors has conductivity = 0 & 𝜇r = 100 𝜇r = 1 for inner and outer conductor Io = 1A(-az) 𝑱(𝑟) = (10^4)(𝑒^-(r/a)^2)(az) Problem has cylindrical symmetry, use cylindrical coordinate system. Find the total current...

Homework Statement During a flume ride the boat plunges 54 feet down a 43 degree incline. Assuming coefficient of friction .12 determine the acceleration of the boat.[/B]Homework Equations I'm really not sure, no mass is given or force. All of the equation I know involve mass or force. The...

Hi sorry it took me so long to respond. Okay I saw it was in bold and I knew it was wrong. I think it was so late at night and I was pretty tired so I didn't take the time to edit it carefully enough, sorry about that. I don't see an option anywhere to edit the original post?

1. My calculus 2 math teacher has us doing a project, involving calculus, on any topic we choose. I chose the topic of calculating work, as in Force x Distance. Specifically calculating work done by lifting a mass into orbit, or to escape velocity. A method is used in my textbook for calculating...

Sorry I needed to update all of the info. I'm specifically thinking of the moon. So this is not a very real world problem. It's so e thing I picked for fun for a math project.

Homework Statement This is a problem I picked for my calculus one class that I would like to solve, then model the solution using the sandbox video game universe sandbox. I would like to calculate the closest stable orbit of the moon, if possible allowing for some eccentricity in the orbit...
