If the water had really covered the entire Earth up to the level of the top of Mount Everest, how much water would be required to do that, how much would it weigh, and what would the effect of the increased gravitational pull by the Sun be - would it have pulled the Earth out of its orbit and crashing into the sun?

There was a catastrophic flood - there is geologic evidence for this (it was over 600 feet deep, but that's not "the entire world" now, is it?). I know that there is not enough water on the Earth for this to have been possible, but its interesting as an intellectual exercise. Thanks in advance to all the smart people that can help me with this one.

if i know a planet's sidereal period and i know how far that planet is from the sun, assuming a circular orbit, how do i find out its synodic period?

i have uranus' radius of orbit = 19.23 AU
and its sidereal period = 84.33 earth years
how do i get its synodic period?
is there some simple formula?

cheers.

This problem is driving me crazy... how would you do...

log2 (3x + 2) - log4 x = 3

Since the bases aren't the same, I don't know what to do >.<

Can someone help me figure out the steps so I can know what I'm doing?... I tried somethin and got 14/3... But it didn't work.

the air is made of many elements besides oxygen and our lungs manage to cope with that just fine, and filter out all of the non oxygen,
but why then is it impossible for our lungs to filter out hydrogen when it is the only other thing besides oxygen
it would seem to me that it would be EASIER to breath water that to breath air, becuase there is less to deal with!!!

when water evaporates INTO the air, we can breath that, and when water vapor becomes water it is going through only a physicall change, nothing is happening to the oxygen that changes its atom..
why then cant we breath under water
do you think we ever will find a way to do so??

I ALREADY KNOW it's poisonous to drink and can kill you or make you blind.

I ALREADY KNOW that there are other commercial antiseptics that are safe and inexpensive.

But for the purposes of my question, they're NOT available, okay?

(In fact, trained medical personnel, please do not answer. Your training compels you to give only a standard answer, which will not only be unhelpful but irritating. I'm not going to go so far as to report such answers as abuse, but I am asking you, please, to assume that I know more about the conditions relating to the question than you do.)

Is methanol too dangerous to be used as an antiseptic on wounds AT ALL, or could it be used in an emergency IF all other supplies were depleted?

A good approximation is that the smallest wavelength possible for a sound wave in a gas is the separation distance between molecules. Find the highest-frequency sound wave possible in an atmosphere in which the wave speed is 403 m/s, the density 1.18 kg/m3, and the average molecular mass is 4.82 10-26 kg. Assume that the molecules form a cubical grid.



assume the air molecules are spherical and that they touch so that the
distance from center of one molecule to the center of another molecule is 2rmolecule

I asked this question last night. but all though I agree with has been written, I dont actual mean physical heating!

As within a microwave oven, microwave radiation causes molicules to vibrate and heat up. Gobal warming has seamingly increased in the last 30 years, around the same time we have been sending more satilates into space for mobile communications, radio dishes and mobile phone masts, and Wi fi. Pigeons flying in the path of radio dishes can be instantly cooked, so with all these's signals and radio waves, there must have an effect, in heating up the atmosphere.

I mean that If radio waves can cause molicules to vibrate and heat up.

Mobile phone masts have been opposed on health questions

A micro wave oven doesn't produce that much heat to cook. With so much radio wave and other radiation criss crossing the globe, then is'nt there a chance then, we are microwaving ourselves
