  1. Hi John, Yes that does make sense, however i guess my question is more so why exactly simply going: 10 cm^3 = 0.1 m^3 ... then (10)^3 cm^3 = (0.1)^3 m^3 ... then 1000 cm^3 = 0.001 m^3, doesn't give you the right answer, whereas going through the process of finding a conversion factor and then multiplying it by the given value works ? Thanks.
  2. Thanks for the explanation John. Thats the answer i came across as well, however i checked it again by plugging the numbers into a unit conversion website and it seemed to give back 0.00001 which I'm still confused about but it seems to work out in the question I'm doing. So I'm still on the sidelines a bit with it. Any reason u can think of why it would have given that number..?
  3. Hi, Ive recently worked on a chemistry question which required a volume conversion from cm^3 to m^3 Specifically the number was 10 cm^3 and it shouldn't have been as difficult as its ended up being, but i eventually got the right answer. However, the method which gave the right number, was in the format of: (10 cm^3 / 1) * (...m^3 / ...cm^3) = 0.00001, of which turned out from (10 cm^3 / 1) * (0.001 m^3 / 1000cm^3), which seems to give the right conversion factor. This was worked out from equating them as follows: 10 cm^3 = 0.1 m^3 ... then, (10)^3 cm^3 = (0.1)^3 m^3 ... wh
  4. Hi, this year i was diagnosed as having had cartilage build up on my left side, specially on the muscle running into the heart, which had moved one morning and resulted in arrhythmia and so forth. Anyway, i have since had sensations that had felt like they were centred in the middle of my brain. Ive had a CT scan, which turned up nothing and my blood pressure is fine. The sensations have felt like sort of slightly pulsating, with tingling regions, moving around in the area of what has felt like my insula cortex, temporal/pariental lobe regions as well as some in the occipital lobe and some in
  5. Also, how exactly is; (n^2 - 1)/n^3 divergent in my answers, they somehow got; 1/2^n from it. could you please explain..
  6. Thanks I will... And would u b able to explain that last Q to me.. Thanks I will... And would u b able to explain that last Q to me..
  7. thanks, that clears it up. also, how exactly does; | 2-i |^2 = 2^2 + (-1)^2 = 5 ? note; | | , is the abs value. and how does; n as a subset of N, where n^3 > 4 , have an infimum of 3, when clearly 2^3 = 8, which is bigger than 4 ?.
  8. Ok, thanks. But when, one side gets the 'i' and the other doesnt.. is that because the denominators cancels out, since your multiplying it by itself, while the numerator keeps it ? Also, how exactly are they split to get the LHS & RHS ?
  9. not sure if this belongs here, However, i was wondering with: 3+i/1-i = 3+3i+i-1/2 ; in the process of solving it, Where does the '2' come from..(in the denominator).
  10. Yeh sorry, forgot to mention that im texting from Australia.. But thanks for the replies.
  11. Hi, i was wondering what number (or number code etc) you put in front of a mobile number to contact someone in the US ? Thanks.
  12. Hi, i doing an assignment in an algebra and differential calculus unit and it asks the following: The brightness, I, of a light beam that illuminates some surface is expressed by: I = (k*sinx)/(r^2), where k is a constant for the given source, r is the distance between the source and the illuminated point and x is the angle between the light ray and surface. at what height should you suspend a lamp over a round table of radius, a, so that the edge of the table is maximally bright. ? and in the old soln, it has: h = a/(square root of 2), but i dont understand how they get there... I
  13. Oh yeah, didn't consider that. Well, nonetheless, are topological defects the result of irregularities in the initial state or from manifestations etc from the process of symmetry breaking. ?
  14. Was wondering, are topological defects the result of the proposed singularity of the universe having irregularities etc..
  15. ok. i guess that answers my question. thanks. but could a gravity wave change a particles spin ?, while it stays the form.
