Homework Statement Three charges q1=+2Q q2=-2Q q3=-4Q. are each a distance d from the origin. What is the magnitude and direction of the electric field at the origin. I'm getting confused by not having d specified as a number. Homework Equations E = Σ kq/r2 The Attempt at a Solution I've...

Thank you two both so much. I feel ridiculous now. :oops:

Homework Statement A Carnot engine extracts 745 J from a 592-K reservoir during each cycle and rejects 485J to a cool reservoir. It operates 16 cycles per second. Find work, efficient, temp of cool reservoir. Homework Equations W = Qh - Qc n=Wout/QhThe Attempt at a Solution I'm sure I can do...

I got it! You guys rock thank you so much! Once I got down to that last x Term I realized that a constant/infinity = 0! Here is my work through!

Thanks for both of your help! Still working on it, sadly.. I pulled out a C so I'm left with: https://www.physicsforums.com/file:///C:/Users/Steven/Downloads/CodeCogsEqn.gif Im not entirely sure what I could pull out of the root.

The conjugate! How could I forget that.. Thank you! Now I have: PS. g is not squared I wrote it down wrong. Let me see what more I can do.

Homework Statement [/B] I feel like I'm missing some theorem which is preventing me from finalizing this problem! It's been driving me nuts I feel like I'm missing something super basic! Ultimately they've given the solution, g/8, so I know this is how I should try to get the equation to look...

Again thank you jedishrfu! I met with a professor in my physics department and she helped me put together a 3 year plan which will have me graduate only a year late. However, I will have time to do both a semester research project AND a summer research project which should set me up for the...

Fantastic thank you again! Some fun stuff to mess with ha!

Thanks Jedishrfu! Makes sense, I leaning that way already. Planned out my next few years and it looks like everything should pan out well!

Hi all. Awhile back I posted about potentially changing schools to study Mechanical Engineering. Unfortunately financially this was not possible. However, my school does offer degrees in physics which I do find interesting. Currently I am studying Computer Science, and I'm considering adding a...

Great! Thank you for all your help, I'm really excited to start along this path. Sounds like I have my work cut out for me! No more easy sailing with this business stuff :approve:

Thanks Jedishrfu! I knew about the first, but the later is new to me. Can anyone suggest any good reads that deal with mechanical engineering?

Hi all! Currently I'm a business major and I realized after a month long car rebuilding project that I should probably pursue another major. My entire life I've been fascinated with building contraptions and what not. I'm pretty behind in the game right now, and would like to do as much...

So recently I became more interested in CAD and i found myself drafting designs for spring airguns cylinders ect. All of-course meaningless given that I have zero understanding of the math behind the design. I am no Mechanical engineer, I am a business student so if I am getting into advanced...
