For this, it's good to have a real industrial example and say what that company does, answering these questions:
How many fermenters? What are the conditions under which they perform the reaction and why? How do they get the most product (and keep the yeast alive? etc.
My example is CSR's Biostil.
What I do for induced currents is look at whether the magnetic field is increasing or decreasing. So for B, its going from a region of high magnetic flux density to lower flux density (as shown by the number of x's in the picture). Now looking at the trailing part of the coil (the part furthest...
Today I had convinced myself that I'd do something for EE2. I got out my journal... wrote the date... and... nothing. Eventually the page got used as scrap for some random maths workings, and it wasn't even marginally related to studying maths either. Grrr.
Speed is constant (20m/s), but velocity is NOT constant, because of the change of direction. Going around a circular track means that direction is constantly changing, which means acceleration (ie not uniform velocity).
:)
Uhm... no... incorrect.
The second part was right though:
x CAN equal zero. Domain for x is all real numbers.
y CANNOT equal zero, because no value of x can ever make the RHS zero.
Therefore asymptote is y=0 (the x-axis) for y=e^x.
lol
On a related topic, my yr 10 history teacher was writing on the blackboard, and he was trying to get everything to fit on the board, basically contorting the words to reach different spots.
Student: Uh sir, you do realise the point of blackboards is to erase things afterwards.
Teacher: ...
Lol I've had those. Though most recent was when my mum took the assignment I was working on away because I didn't go to eat dinner when it was ready...
Wahay! Holidays!
I suffered from premature word expulsion during the speech today... my nice effective opening was murdered when I said words in the wrong order. grrr
Ah well, only teachers and marks will remember it next term.
