I agree, unfortunately I'm not comparing two spectra, but rather just answering for a variety of spectra is the solution optically dilute? Is it Optically thick? And not sure where the cut off is, can't find a value anywhere
If you're reading a graph of absorption coefficient(cm^-1) versus wavelength(nm), how can you dtermine if the solution is optically dilute? What about optically thick? Thanks

I'm supposed to determine if a bunch of materials have a high or low impact strength. I did the hard part and determined that the impact strength for each material, but I don't know a relative scale. What is a high value on the izod impact scale test(it's measured in joules). Any idea?
This is a general question, not specific to any one homework problem just a concept I must understand in order to figure out all of my homework. Does clustering tendency increase as atomic radii between substances A and B become more similar? Clustering tendency may not be particularly clear...
Hey guys,
I worked through this problem and feel as though I made a mistake. I attached the figure, without it it makes no sense.
Question: The suspended load weighs 600 lbs. Determine the reactions at A and B.
Examining just the bottom bar, I summed the forces in the x
and got Ax -...
yeah I'm going with text is wrong, .125 is found by not dividing the radius by 2 and then dividing by a factor of 1000...haha only thing I could find out, but thank you!
This doesn't seem particularly hard, thought it was simply an F/A situation but apparently not. A fiber with a diameter of 25 micro meters is subjected to elongation load of 25 g along the fiber axis. What is the stress on the fiber? Is the applied stress a shear or a tensiles stress. I said...
thank you I was feeling like an idiot that I couldn't girue this out, I'm glad it doesn't appear to really be a trivial process. I appreciate the help,

I understand what you're saying about the picutre now, but I don't understand what you're using to compare C and A. I know where a is and i know where c is but i don't know the other length of triangle built between them, so i'ts unclear to me as to what the link is between thier length

I'm trying to solve for the ideal c/a ratio of hcp packing. why doesn't c/2 =a/2, looks like they pass through the same amoutn of radius's so I'm not sure the geometry to use. Used this pic http://www.engr.ku.edu/~rhale/ae510/lecture2/sld013.htm [Broken] but it is more confusing to me how 1.67...
I'm confused based on what I've been reading. Does short-range order for a crystal change when it is melted, or is onyl long range order affected by the state of matter an melting has little to no affect on the short range order of the crystal. Is that right or does the shrot range order change...
I've spent about 6 horus this weekend trying to construct to build a paper tower that will support thick textbook 14 inches off the ground. the requirement is that it weigh less than 15 g. you can use tape and paper and that's it. Cylinders cannot exceed 5 cm in diameter. Tried making a bunch...
Yeah, the trick to the problem was actually that you can't treat the cut out as a sphere, you treat it as a disk and inherently an infinite plane. The hint about radius cutout being very small was that you treat it as one dimensional. The radius cancels out if you treated them both as a sphere...
A uniformly charged spherical shell with surface charge density omega contains a circular hole in its surface. The radis of the hole is smalle compared with the radius of the sphere. What is the electric field at the center of the whole(Hint: the field within the whole is the suprposition of...
I understand that, but I'm just given the information above, which is simply an electric field, so I couldn't find the exact charge density any more than what I have above, could I?
Question: The electric field on the surface of an irregularly shaped conductor varies from 56.0 kN/c to 28.0kN/c. calculate the local surface charge density at the point on the surface where the radius of curvature of the surface is (a) greatest and (b) smallest.
I am stuck as far as how to...
Question: A pyramid with horizontal square base, 6.00m on each side and a height of 4.00m is placed in a vertical electic field of 52.0 N/C. Calculate the total electric fluc through the pyramids four slanted surfaces.
I know you can figure out the flux through the base = 36 m * 52.0 N/C...
