Science & Mathematics - 19 January 2007

Ok, we all know light is constant no matter what, but we also know that light coming at us from stars are red-shifted due to the Dopler affect.

So my question is this:

What is it REALLY like to travel at extremely high speeds, such as close to the speed of light? It seems to me that if light coming at you from sources moving away from you would red-shift, at some point, they would shift to infrared, then eventually visible light would look like radio waves. But at the same time, higher frequencies such as x-rays, alpha, beta and gama rays would become visible light as you moved away from it.

In front of you, the visible light would blue-shift. Eventually, visible light would become harmful radiation, radio waves would become visible, and harmful radiation would probably kill you.

The only thing that would look normal would be when you look to the side.

Am I off base with this idea?

On some days, it's important to me to know my mail (snailmail not email) is here as soon as it is. Has anyone heard of a device that would notifiy me when the lid of my mailbox has been opened? etc. ? (a light and a sound would be great - just in my room, not to alert the whole neighborhood) i'm thinking of something or somethings that I could buy say at a Radio Shack

Its number 8 from the 2001 free response, which I have reproduced below:
Account for the following observations
a)Even though NH3 and CH4 have similar molecular masses, NH3 has a much higher boiling point (-33C), than CH4 (-164C).

b)At 25 C, and 1 atmosphere, ethane (C2H6) is a gas, and hexane (C6H14) is a liquid

c)Si melts at a much higher temperature (1410 C) than Cl2 (-101C)

d)MgO melts at a much higher temperature (2852C) than NaF (993C)

thanks

Does anyone know where I can download the solutions manual / answer key for "Fundamentals of Physics" by holliday, walker & resnick 7th Ed, really helpful when reviewing for exams.

I am looking for the PDF version and not the actual book.

Thanks

To test the quality of it's paper clps , a manufacture randomly collects 100 paper clips from each batch. After 10 random samples, the following results are obtained.

Sample A B C D E F G H I J
defective 2 1 2 0 1 2 1 4 2 3

A) What percentof the paper clips are defective in sample A?

B) What percent of the paper clips are defective in the total of samples A to J?

c) If the sample K is taken, how many defective paperclips might you expect? Select the best answer for each number.
6 : yes, no, maybe
3: yes, no, maybe
2: yes, no, maybe
0: yes, no, maybe

Any help in explaining this would be great. I can't get ahold of the math teacher and I want to finish this lesson. Haven't even gotten to the real questions yet !

The delivery of mass in a precise unit of time & location related to the acceleration of light & the laws of the universe. I'll explain E 5 equivelent to V 5 = V 22 C 3 (see 3) C2 a factor of one or 1/27 the sum of two add S for more than one 19 54 a factor sum of 2 or note 12/27/1954 V M 22+13 ='s 19:35 or V 2 times V5+2=7:35pm spher location longitude M one's three or III.sum 54' C 2 numerical charactors exprss as 00" that doubles express as "w" so the complet answer is 12/27/1954 @7:35pm or Navy time 19:35 on longitude III.54'00"w
So where is my monetary gifts associated with my academic achievement the delivery of mass threw time express as E=mc2 ?

I haven't had to do anything like this in years and it's driving me insane. Any help would be appreciated, I know it's impossible to download a graph to "yahoo answers", step by step instructions would be wonderful. Please explain as simply as possible "Algebra for Dummies" style .... thank you in advance, I look forward to reading some interesting responses.

I am taking an Art History class at school and my teacher brought up a number (1.67) that the Greeks found out is the number of beauty. I was wondering if anyone else knew anymore about this? Or even the formula to calculate beauty? It is fascinating to me as I am an art major.
