just wondering

and i made one out of a telivision that i didn't want anymore and i can't get a full span of an image on the screen (although te only thing i have plugged it into are a mobile mp3 player and the phone line) will voltage or current depend on how big the image will be

and how do i span the image

A 0.0047 microFarad capacitor and a 68mH coil are connected in series. At what approximate frequency will this LC circuit resonate?

____a. 194Hz
____b. 52KHz
____c. 8.9KHz
____d. 4.9GHz

i have tried to figure this question out with no luck. it in volves scientific notation with negative components which leaves me very much in the dark. any help will be greatly appreciated and explain and show how you came to your answer

I was trying to use Vpulse in the source library, but V1, V2, Td, Tr, Tf, Pw, Per seem like like too many parameters to set for me.

I get this error when I use an opamp where I specify Vcc/Vee. When I use the idealized opamp part I don't get this error.

Anyone have any idea how I can troubleshoot this?

This is regarding furniture. I find that centre tables with glass tops are fitted with two to five metal caps. May be these caps have same thermal expansion as that of glass. Then these metal caps are used for holding frame or stand. But I am unable to understand the technology used in joining the metal caps with glass plate. Please tell me.

we would like to do a study regarding a hospital in our community. Any help with the concepts that we might put in. Like what are the effects of poor design in the wastage of energy which results to higher cost of electricity...

"Page 220 Table 48. "Deflections and Bending Moments of a square plate with four sides supported elastically." The text just below the table deals with varying poisson's ration and states that it has little effect on deflection at centre. Then a new value of poisson's ration is used but the deflection constant changes by an order of ten. Are the values in the table correct? Or the values in the text?"

This is the only text I can find that states quite so simply an algorithm for use with plates supported in their corners so was quite disappointed to find that I am not sure which value to use! I am going to see if the table value "looks right" for now but would appreciate your comments.

Hi I realise this is not the most fantastically interesting question for a Friday afternoon but....just got a letter saying my electric meter is being exchanged for a new 'smart' or OnStream one. Does this mean that the new meter will start at Zero?
By some magic power I have paid no electricity since June since I switched suppliers (I am hopefully lost in the big computers at British Gas) and if this new meter starts at zero and the old one is defunct I am really hoping that will wipe my usage history and it means they can't backdate bill me when they finally workout I've never paid them a penny!
Thanks
Josephine

Or how do you convert units from pF/inch to pF/metre.

I have a formula but it assumes unit to be in mils and inches, I need mm and the result to give me a capacitance per unit length (in metres).

I have envisioned this, and pictured a large wooden water wheel (basically the turbine) connected to a small-scale AC hydro generator, like those used in dams, and a high-voltage transformer and small power pole and line, to power a remote house in the woods, by a stream. How feasible is this setup, and if not, what are other feasible setups for hydroelectricity are there and how might I carry them out?
