Gah! I'm not exactly expecting an instantaneous reply but I figure it doesn't hurt to ask. There's a problem (actually one of many problems) in Chemistry that I absolutely can't figure out. Here it goes:
"An energy of 2.0 x 10^2 kJ/mol is required to cause a cesium atom on a metal surface to lose an electron. Calculate the longest possible wavelength of light that can ionize a cesium atom. What is the region of the electromagnetic spectrum in which this radiation is found?"

O_O' uuhhh can you say that again, but in english? ^^'
A classmate tells you, " Finding the coordinates of a midpoint is easy You just have to find the averages." Is there any truth to it? Explain what your classmate means...
Describe a way to find points that divide a segment into fourths.

Um well LOL do you want the answer or to do it yourself? If you want to do it yourself well check out Planck's equation as a start. Given the energy required to remove and electron from cesium. hope that helps

Frlz? B, F, F "
I didn't feel like reading the text book
<-----A lot of homework for being absent, on a side note thanks Slinger^^
"The monitor is connected to the computer's video port or wall outlet?"
o_O its both... isnt it?
Ok, Ultrasounds are used as a diagnostic tool for the body. The book say's that their's suppose to be Six, as well as six sub areas....
Obstetics
Gynecology
Male Reproductive structors
Head and neck
Abdominal
and one more for that.... but I cant find it...
I know the sub areas are under Abdominal and they are:
Hepatobiliary tract
Pancreas
Spleen (^_^ YAYZ SPLEEN!)
Kidneys
Aorta (and other blood vessels
Gastrointestinal (or GI)
But for the love of cookies, I cant remember what the last one in the first six is x_X Some help would be appreciated if your know anything about this stuff xD

Thank You so much Feral Nova but I was talking about a computer monitor (The thing I'm using to talk to you on CV) XD
But thank you for giving me that piece of information...it may come in handy in High School^^

o_O No... um.... that bottom part.... was MY question xD I'm asking someone for help for MY homework! lol
I know what a computer monitor is... I'm not that much of a ditz xP

OMG I just saw this! XD
Thanks a lot for even bothering to do all that, and it was a while ago but I do think you could have the correct answer! ^^ MR got herself a smart man. ;)
Question:What is Strawson’s argument against Cartesian dualism in the passage below?
It is here that we come – at last – to the central difficulty in Cartesianism. It we are to talk coherently about individual consciousnesses or minds, or about individual items of any kind whatever, there is one thing at least which we must know. We must know the differences between one such item and two such items. We must know, that is, on what principle such items are to be counted. And this means further – if they are supposed to be items capable of lasting through a period of time – that we must know how to identify the same item at different times. In general we have no idea what a so-and-so is unless we have some idea what a so-and-so is. If we have no idea of how the notions of numerical identity and difference apply to individual consciousnesses then we really have no clear concept at all of such items.
