Ok, so I was reading this article today about electromagnetic fields and it gave me a weird idea that leads me to a question. I learned in physics that electric fields and magnetic fields exist perpendicularly to one another as well as inversely in their magnitudes i.e. as one goes down the other goes up......what I inferred from this article was that this inverse magnitude thing is not necessarily always so, which is why complex numbers are useful in calculations involving this stuff....so my question is, what kind of circumstance would make it so there wasn't a direct 1:1 inverse relationship between the two i.e. one of them goes down, but the other doesn't go up as much as it should etc....

If I knw the power and the rpm (indicated on the plate), do I make use of the equation: Power = Torque * rpm? Will I be calculating, starting torque or working torque, with this equation?

Next which among the following drilling machine is the most powerful?

1.Power = 500 W and rpm = 500

2.Power = 500 W and rpm = 1000

3.power = 750 W and rpm = 2000

4.power = 750W and rpm = 3000

I mean if we wanted to collonize something I think the moon should be the first obv choice and not mars what do ya think? I believe by the time we are ready to collonize a planet nanotechnology will be up and running and we will have abilitys we dont have thoughts about now. So it just makes sense that we start with something closer then mars and something we know more about? Plus the moons smallness might actualy make it better for collonizing in some ways.
