I'm in the final year of my bs. in mechanical engineering.For my senior project , I would like to conduct a study on the feasibility of harnessing wind energy for electricity in my country (I don't think it has been done here before and we have a power problem and a pollution problem). My...

stuff like -What degree did you study -What a typical day is like for you -How closely you get involved in what is being irrigated (plants ,trees...) -What advice you would give me (a mechanical engineering student who wants to work in a profession related to agriculture

Thanks again tiny tim :) . I guess I do need to go back to my book and study the concepts a little more. :D

Thanks for the welcome message guys :). I've heard a lot about Physics Forums-everyone tells me its awesome :D. In reply to tiny-tim, I derived my answers from these formulas: a)C=Aε0/d - Capacitance is based on the geometry. The area of the plates didn't change, and the permitivity of free...

I think I know the answers to the question I am going to ask but I am just going to make sure. This is going to be quite simple for most of the experts here so here goes: If we have a parallel plate capacitor and we double the distance between the plates while keeping the charge Q on the...
