  1. yea i would do that if it werent under the house... got 3 more exams to do for school before i have anytime to fiddle with the settings on it.
  2. All i know is that it is a Belkin Wireless Router modem model number is unknown. Will keep looking for the model number.
  3. Now this one im not sure can be done but like my dad always says "the only stupid question is the one thats not asked". My little cousin (who has been living with us for most of this year) has a bit of a download-a-holic problem and using up the limited upload/download allocation, which is 20Gb per month. It should suit us fine and last the entire month. My question, is it possible to limit what speed internet she can access via the wireless network? So that our download limit is not being assaulted so fast. If you need router specs let me know i will get those for you. Cheers Crozius
  4. Currently doing Nuclear physics this semester and have a whole booklet of questions for homework and what little spare class time we have. Stuck on 1 of them, dont understand how im meant to get the answer (which ill put in brackets after the question.) Also, ill write the isotopes with the atomic number before the element then the mass number after it... couldnt find the sub/super script buttons A Sulfur nucleus 33S16 disintegrates by ejecting a proton 1H1, leaving behind a phosphorus necleus 32P15. If 9.24MeV energy is liberated as kinetic energy that drives the two fragments apart, how much of the energy goes into each particle? (Answer - 8.661MeV for proton and 0.289MeV for the nuclide formed.) Cheers any help would be appreciated. Crozius
  5. All of that doesnt answer my question... I use a TI-84 plus calculator and it doesnt give the graph that im expecting, nor does it have the qualities that is required. Any method you guys can come up with that i can use on paper then check with the calculator would be better so i can show working. Thanks. Xcel yes, lake tuggers, which teacher you got?
  6. I need to find a function that can be proved using calculus techniques. I have used every local source of information to find a method to work this out but alas... the answer eludes me. Heres the question: Following 5 point lie on a function: (1,20) (2,4) (5,3) (6,2) (10,1) Find an equation that passes through these points and has all the following: 3 points of inflection At least 1 local minimum and local maximum At least one Critical point (eg max/min/intercept etc) is not at a given point The curve is continuous and differentiable throughout The equation is not a single polynomial, but must be a piecewise-defined function Now I know that theres gonna be many different functions. All I need is a method to work one out for myself. I am at a loss of how im meant to get this... Thanks for any help provided Crozius
  7. Is there anything this site cant do? http://en.wikipedia.org/wiki/Nitrous_oxide#Manufacture
  8. Im not much of a help in decrypting this. But i have taught myself a few simple ciphers and to me that almost looks like a rail cipher (think thats what that cipher is called)... Try running that text through some of the programmed ciphers on this site -- http://www.antilles.k12.vi.us/math/cryptotut/intro.htm
  9. Which is a pity because i dont have any resistor wire.
  10. I know, what i plan on doing is linking both of them up to some insulated wire which are connected to some aluminium foil in salt water. Then i know that they are discharged after a few days.
  11. Yep, well at the moment i only have two disposable camera capacitors that are roughly 300v so i am told. So i will try with one then put the second in series or whatever.
  12. Just general pros and cons, like it may be fun (pro) but it can be dangerous (con)
  13. Now i know there have been other posts about the same subject, i have done a search and looked at most of them. If this is not the right spot to be putting this thread it can be moved if needed. Onto the subject. I have been looking around and various coilgun designs and settled on Jeff Hoves design (http://www.jeffhove.com/robots/coilgun.html). I thought it best to start off small, running off just a AA battery and a single Capcitor as shown in the design schmatics. Over time i will slowly get more knowledge into the design and theory behind the project, in which i will increase the voltage and the number of capacitors etc. What tips can all of you give me for a beginner into coilguns? What are the pro's and con's of this little school holiday experiment? I have seen that some of the larger coilguns have ammeters to see moniter the capicitors voltage etc. Would that be needed for this particular design? I know of all the safety things like the 300v (approx) that can be stored in a capacitor in just a disposable camera. Thus the reason of rubber soled shoes, rubber gloves and plastic handled screwdrivers. Safety is my first concern, if i wasnt confident enough that i was not gonna kill myself i wouldnt consider doing this. Thanks for all the help. Crozius
  14. 1, 18, 521, 4, 2 are all incorrect. 68cents i am unsure of, i got this from one of those late night game shows. Been really annoying me of what the answer is so why not use some of the brilliant minds here.
  15. How many cents are here? It is a lateral thinking puzzle...so think outside the square. Give me your working too. Six cents 35c Four Dollars 12 Cents $0.68
