The Attempt at a Solution
I apologise for not making an attempt, this is just unlike anything I've seen.
I'd appreciate if anyone could...
I'm having trouble finding the equation normal to the plane for part (ii).
The vector equation I got for part (i) is r=(1/2,1,2/3) + t(3/2,2,-2/3). How do you deduce the normal vector from this? The answer is the vector (9,12,-4). I've tried anything but don't know where they got this result...
Hi
This may sound like a trivial question, but I'm a beginner physics student and need some help understanding what the k constant is from Coloumb law.
F_e = k_e\frac{k_1 k_1}{r^2}
where
k_e = \frac{1}{4\piε_0}
I did read a bit about it and I have two questions...
Hi
I'm kinda confused with the difference between reactive and apparent power. In my understanding, reactive power is basically the power absorbed by either electric or magnetic fields that is later returned to the source. So what is exactly is apparent power?
thanks
