I'm starting a new job. I want to fit in (or at least not get on anyone's nerves), but frankly I've never worked with engineers before. I'm easy to get along with. I figure that will help. Maybe my best attribute, as they might see it, is I care about the details. In fact, I can get down right obsessed if given the opportunity.

I'd appreciate hearing your thoughts on this subject. Thank you.

I'm working on my homework by myself, but I can't seem to figure out the answer to this question.
The physics book explicitly states "Electric field lines begin at positive charges and end at negative ones."
So, in the case of electric fields created by point charges - the answer is definately no.
However, what about in the case of a closed circuit?? Are the electric field lines of a closed circuit in the same direction as the current?

My Physics book doesn't really say anything about electric field lines in a circuit.

Any help would be appreciated - thanks.

at depth in cm below the surface of a fluid in density g/cm^3
a solid circular cylinder of lenght 10cm and radius 2cm has its axis vertical, and its top end is 15cm below the surface of a liquid of relative density 1.3.calculate the thrust of
A) the upper AND lower end of the cylinder due to the fluid

from the results deduce the loss of weight of cylinder on immersion in the fluid.

If you was travelling at the speed of sound, in a dune buggy,
along a dark and lonely night, with a north easterly, blowing
up your ring piece, and you got very hungry, is it tuesday.

I have my own way to solve it, but Id like to see if someone of you can teach me something different.

THIS IS NOT A PIECE OF HOMEWORK. This is a serious question, addressed to Mathematics lovers.

Later!

You would like to see the effect of shutting off the production of protien Z in the cell. You have at your disposal to alter the cell however you wish (in vitro experiment). How might you shut off the production of protien Z without altering transcription of the gene encoding for protien Z and without shutting off production of any other protein?

Im particulary talking about compressed helium. Are the helium molecule soft? How does their shape return after decompression or inserted into a balloon? How do they differ from nitrogen and hydrogen molecules or even water molecules?
