This address http://news.yahoo.com/s/ap/20060914/ap_on_sc/puffy_planet details a planet so "puffy" it would float on water.

For some reason, I always thought of planets as big round things that could actually support weight, but this seems to indicate otherwise.

So can someone give me a precise definition of planet? This thing seems to be made of hydrogen and helium - so what makes it a planet?

Thanks!

I know that to be collinear, two or more points must be in the same line. But do the points have to be coplanar in order to be collinear?

Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 60 mi/h.

1. Assuming that they start at the same point, how much sooner does the faster car arrive at a destination 13 mi away?

2. How far must the faster car travel before it has a 15-min lead on the slower car?

Thanks and please show me how you did it!

need help w/ integrals. i will use "S" for the integral symbol.

sq = square root (e.g. sq.x = square root x)

1. Scos(pi)x (i know this is an easy problem, but the pi is throwing me off)

2. S(sq.x)lnxdx

3. Sxcos(pi)xdx

4. find volume generated by revolving region under graph about y-axis

f(x) = xsinx , x E [0, pi]

5. also, can anyone explain why multiplying (1/x) by (x^n+1) equals x^n?

thanks for any help you can provide
