K so I know that lots of people ask it and bla bla bla, but this question is different... WHY does everyone fall for that Rayleigh bs? There's dust everywhere and light doesn't hit it and freak out, shining blue on everything! So WHY is the sky really blue? Does it have anything to do with Uberblutomiumide?

The other night I went to bed and forgot to remove my earrings, I do this often. Next morning I took a shower with both earrings still in my ears, I do this often. Got out of the shower with both earrings still in my ears, wrapped a towel around my wet hair. Then I did my usual routine - dress, make up and hair. I was getting ready to run some errands, went into the bedroom to get my purse and spotted my earring on the floor. Checked my earlobes, and yes, one earring was missing. The earring on the floor was the match to the other, which was still in my ear, but the earring still had the back on it. I have had many earrings fall out, but I find the post in one place and the back in another. This time both were in place, together - connected, the back was on the post. Now I know that I have an intelligent dog, but she's not that good! We have had some "unique" things happen before, but this was really odd. Any thoughts?

How would I go about finding the ratios between these 3 different types of Kinetic energy--

Rotational
Translational
Intermolecular

I'm sure it has to do with the moment of inertia, mass and molecular bond, but only being through Chem112 i am not sure where to start. I am just looking for the 5% ballpark. Are there any assumptions I need to make.

Anything helps, Thanks a Bunch

But I've heard that there are very few jobs in the field, and astronomers don't get paid that much. Is there any other interesting job that I can do that requires a degree in engineering, or physics?

why doesnt the dilution of the buffer (NaOH and acetic acid) not change the pH of the buffer by very much..why not?

why isnt deionized water not likely to have a pH of 7 ?

compare the change in pH with the addition of acid and base to deionized water and to your buffer. explain the difference

The air in a room with volume 180m^3 initially contains 0.20% carbon dioxide. Air with only 0.07% carbon dioxide flows into the room at 2m^3 per minute, and the mixed air flows out at the same rate. Find the percentage of carbon dioxide in the room as a function of time. What is the percentage of the carbon dioxide in the room after half an hour?

Yes, Don"Barny Fife" Knotts went to space first in THE RELUCTANT ASTRONAUT, then nearly a decade later, Sherriff Andy Taylor, a.k.a. ANDY GRIFFITH went to space to collect junk on the 1979 TV series SALVAGE!

So, both Andy Taylor and Barney Fife have gone into space...so do you think that ANDY GRIFFITH needs to return to space in a Space Shuttle to complete the cycle?

A man 190 cm tall stands 2.5 m from a plane mirror. His dog, 30 cm tall, sits 1 m in front of him. What minimum mirror size is needed for the man to see all of his dog's reflection?


I got:
h=H * (i)/(i+o)
=.3m x (2.5m / 4.0 m)
h=.1875 m

But this does not take into account the man's height. Please help.
