Science & Mathematics - 17 October 2006

I know this sounds kinda crazy but I am doing an "alien" project. We were assigned different planets where the alien was supposed to be from. My dumb*** teacher assigned me earth. Not for anything but how often do you step outside and trip over an alien? Anyway, I just need basic information such as average temperature, distance from the earth, and all little fun things like that. A list of factual websites would really be helpful. :D Thanks.

I'm close to a solution, but encountered a contradiction with 10 squares left. As for original clues, I'm unsure of my answer to 3 times the integral of X squared dx (I said 1), and one square looks like -(2^-2), which is -0.25 (I used 2), so that can't be right either.

Also why are these pebbles shaped like this? I take it their distribution has something to do with their shapes? Would like to hear answers from any geologists or geographers out there thanks.

Time dilation on a neutron star.
That sounds a bit better than 20,000 years. ;)

So in one day on a neutron star equals about 27 1/2 hours on earth. For each year you would age 53 days slower than people on earth. If average life expectancy was 72 that would be a couple years longer.

Not much difference at all.

Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used.

Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and 111-trifluoroethane (C2H3F3) has a density of 2.27 g/L at 19 °C and 0.497 atm.


Calculate the average molecular mass for this sample.
________ amu

Calculate the volume percentage of C2H3F3 in the sample.
