I am wiring into a 3 phase 208v busbar. I want to split each phase to 120v with the neutral. I have no "wild leg". I am using 10 ga stranded copper wire for the 3 hots and the neutral. My loads consist of 20A on L1, 20A on L2, and 10A on L3. I want to know what the current will be on the neutral. If I can use the single existing 10 ga wire for each leg (30 amp capacity)? If I need to worry about harmonics?

Theoritically if I could ride a plane travelling at the speed of light and hold a mirror infront of me... what would I see considering that my image is also travelling at the speed of light? (Relative to light it will be faster than light)

we know that after light passes through a higher density matter(e.g prism) its speeds reduced and causes a phenomena what we referred to as refraction. However, after it has passed the matter light is able to retain its normal speed again. So, how come light is able to return to its normal speed after losing its speed while passing through the matter?

Our Organic Chemistry Professor gave us a challenge question for extra credit. We have to write a paragraph on the chemical formula of benzodiazepines and I'm having a really hard time. I have a D in the class right now, and I really could use the extra points. So far I've come up with this
R = Methyl Methyl- carboline-3-caroxylate (CCM)
R = Ethyl Ethyl - carboline-3-caroxylate (CCE)
R = Propyl Propy - carboline-3-caroxylate (CCP)
I looked up the chemical formula for Ativan and they were 7- chloro -5- (o-chlorophenyl) -1,3 - dihydro -3- hydroxy -2H- 1,4 - benzodiazepin -2-)
Do you think this is good or do I need to be more specific?

0 x 1 = 0,
0 x 2 = 0,
...,
0 x 999999=0,

infiniti x 1 = infiniti,
infiniti x 2 = infiniti,
...,
infiniti x 999999 = infiniti,

So, 0 x infiniti = ???
