Wow. That is why you are the master, and I am but a lowly grasshopper. Thanks. I get it now. Sad addition to my story- my husband knew what was going on, and he didn't even take Physics in college :( If it is ANY consolation, biological sciences do not elude me the way physics do. I will...
How incredibly stupid will I sound if I say, "no, I still don't get it?" Why do the outputs equal each other if connected in parallel, but are not equal when connected in series? And what happens if the sources are NOT the same voltage? Argh.
Homework Statement
Suppose that 2 identical photoelectric devices are connected to the same electrical circuit, and the devices are connected in parallel with each other. Compared to the voltage generated by a single device, the total voltage supplied by the parallel devices will be...
Homework Statement
Calculate fractional saturation (YO2) for hemoglobin at venous O2 pressure (30 torr). Assume that p50 for hemoglobin is 26 torr, Hill constant is 3.
Homework Equations
YO2/1-YO2=(pO2/p50)^n
The Attempt at a Solution
(30/26)^3=1.54=(YO2/1-YO2)= 1.54 -...
I can see where you were going with it- we just are given certain equations to use and the textbook has got to be one of the worst for anything (I hate! Wiley text) and doesn't really explain the equations very well. Unfortunately, neither does my professor
:( so we are forced to look at...
Oh- I think I figured out how to get how many liters of EtOH are needed-
0.1368 M * 40 L = 5.472 mol
5.472mol * 46g/mol= 251.71g
251.71g * 1mL/0.79g= 318.62mL
If anyone knows how to do this, can you check my work and let me know if it's right. Thanks again!
Homework Statement
Ethanol in the body is oxidized to acetaldehyde by liver alcohol dehydrogenase (LADH). Other alcohols are also oxidized by LADH. For example, methanol, which is mildly intoxicating, is oxidized by LADH to the quite toxic product of formaldehyde. The toxic effects of...
OK, so I now know where I'm having trouble...I don't know what the ORIGINAL value for q1 is, so if anyone can point me in the right direction to determine q1 before, maybe I can do q1 after...thanks
oooo, ok so I've got part (b)...which I got by simply dividing q123 by C12...however, how to get part (a)...that's the tricky part...I'm not really sure how to manipulate these numbers to determine q1 in the first place...
uh-oh...ok so I have that C123=3.42microFarad, which will also give q123=3.42e-4C...since C3 will be essentially taken out of the equation, I would need to figure out what the new total capctitance is without c3, right? Or did I miss something?
Homework Statement
In figure 25-29, a potential difference of V = 100 V is applied across a capacitor arrangement with capacitances C1 = 13.0 µF, C2 = 6.76 µF, and C3 = 4.14 µF. If capacitor 3 undergoes electrical breakdown so that it becomes equivalent to conducting wire, what is the...
so this is apparently not the equation because no matter how I manipulate it, I'm not getting the answer...someone, please help...this is my last homework problem for this section...
