How do we know all of this? What specific tools, and procedures, and other things did we use to find such info?
Info from Wikipedia.

Saturn is an oblate spheroid, i.e. it is flattened at the poles and bulging at the equator; its equatorial and polar diameters vary by almost 10% (120,536 km vs. 108,728 km). This is the result of its rapid rotation and fluid state. The other gas planets are also oblate, but to a lesser degree. Saturn is the only one of the Solar System's planets that is less dense than water, with an average specific density of 0.69. This is a mean value; Saturn's upper atmosphere is less dense and its core is considerably more dense than water.

A 4.5 kg dog stands on an 18 kg flatboat, and is 6.1 m from the shore. He walks 2.4 m along the boat towards the shore, and then stops. Assuming there is no friction between the boat and water, find how far the dog is from the shore.

Imagine the dog moves leftward and the boat moves rightward, but does the center of mass of the boat + dog system move?

i'm going to rephrase lance's question here, b/c i find this to be quite an interesting question, but i want to know if it's even possible?



if i have, on paper, a diagram consisting of 3 rows of 4 dots; starting wherever i want on the paper, not taking the pencil off the paper, and only using 5 straight lines, how can i cross out all 12 dots, while ending up where i began?

the diagram looks like this:

0 0 0 0
0 0 0 0
0 0 0 0


is it possible to end up where you started?

3 part?
1.which ion out of Na,Mg,Al,S,Cl,K,Ca, and Ga is the most stable

2.arrange these elements from LARGEST to SMALLEST radius

3.explain why the radius varies as it does

thanks for the help!!!

Have you ever thought, only in the last 100 years, we excel so much in technology. but prior to 100 years., it seems like humans were not improving. Are we smarter than before?

In the ammonia (NH_3) molecule, the three hydrogen (H) atoms form an equilateral triangle; the center of the triangle is 9.40*10^-11 m from each hydrogen atom. The nitrogen (N) atom is the apex of a pyramid, with the three hydrogen atoms forming a base. The nitrogen-to-hydrogen atomic mass ratio is 13.9, and the nitrogen-to-hydrogen distance is 10.14*10^-11 m. Locate the center of mass of the molecule relative to the nitrogen atom, and explain how you got your answer.

This is probably a really dumb question based on completely misunderstanding the whole idea ... but I'll ask it anyway.

There is a cosmic background radiation which is is pretty uniform in all directions but with a few ripples in it.

As far as I understand it this uniform scattering of photons started to propagate out shortly (in cosmological terms) after the big bang.

What I don't get is this. The solar system (and our galaxy) did not exist at the time, and the matter/energy from which it was formed came from matter 'condensed' from the big bang. Since that matter could travel no faster than the background radiation and would generally be travelling less quickly, how can any of the radiation be still passing us or coming towards us. I get that what we are detecting is like looking back in time but I don't see how any of this energy could be effectively behind us the race away from the big bang, even if space and time themselves are being inflated in the big bang.
