I have the solution manual, so this is more just a question of why, rather than what.
I understand that with the switch open:
vA = 3v
vB = vC = 0v
i0 = 0.25 mA
When the switch closes it creates a short that makes the two 6kΩ resistors irrelevant...
I bought a ti86 off craigslist for about $30 a few years ago. I'm very happy with it. I think the interface is much more intuitive than the ti84, plus it has more advanced features (eg complex numbers). Since they are older they can be found pretty cheap. Many classes will let you use...
I remember the first time I heard someone call a soda 'pop' I thought they were joking and laughed.
Anyway, here's an interesting link I found a long time ago that this thread reminded me of.

It's similar to this pop vs soda but for...
Still not sure I understand what you want, but it sounds like a perpetual motion machine.
Anyway, from wikipedia:

Energy conversion efficiency:
Solar cell 6–40% (technology dependent, 15% most often, 85–90% theoretical limit)...
Are you proposing powering LEDs with a PV cell which then illuminates a PV cell generating some power which is fed to LEDs and etc?
If so, no that absolutely will not work. It would be a perpetual motion machine. If such a simple setup could produce infinite power then it would be in...
Well thanks for both the replies. It would seem my exposure to this is just the tip of a much larger iceberg.
I find the concept of building models to fit data very interesting. What sort of course would cover this in more detail? Would a calc based intro to statistics course be good?
I don't know what a Planckian distribution is, but it has nothing to do with Planck's constant. Just happened to look similar to blackbody radiation curves, with the non symmetry and long tail. Just kind of figured there was a more general name for that kind of curve, but guess not. Thanks...
I was plotting some data and got a curve that was instantly recognizable as a blackbody radiation curve. The data has nothing to do with blackbody radiation though, and I was wondering if there was a more general name for this type of curve?
To be clear, I mean a curve like these...
I took a LA course in the spring, and was interested by the least squares method for building models. I decided to practice this concept by attempting to build a model that would predict ticket sales for the Mega Millions lottery given the jackpot amount. I have 249 data pairs of jackpot and...
When food is converted into energy its chemical bonds are broken (or new ones are formed) and energy is released. Those bonds have some very slight mass, and the resulting energy has the same very slight mass.
Going back to your original post, I'd like to point out that it's total mass and...
I was thinking about making a program that did exactly this. I gave up after thinking about it for a little bit because of the large number of possibilities that would have to be presented. If you wish to take 5 classes and each has 4 possible time slots that's 45 = 1024 possible combinations...
Need more specific details before we can really say. Here are some needed details:
CPU model?
Graphics card model?
How much RAM?
Does it include keyboard/mouse/monitor/speakers?
Also, why does it have Vista? Is it used? You can get a new PC with comparable or better specs for the same...
Wow, I must have integrated that 4 times and came up with 5/3 each time. WA even shows the correct answer. Don't know how I missed it repeatedly.
Thanks.
