I am not sure if there is a specific name for it. I am interested in the nursing field and I am pretty sure that I want to be the nurse that takes care of the newborns in the nursery.

If weight is the measure of the gravitational pull on something, then why wouldn't a heavier object with the same surface area(wind resistance) as a lighter object fall faster. Wouldn't its greater gravitational pull make it fall faster toward the Earth. Does it actually fall faster, but it is nearly incalculable because of its size in comparison to the mass of the Earth?

In my Calculus textbook it doesn't say.

I'm asking because of a specific question it gave, where the series x-(x^2)/2+(x^3)/3+....(-1)^n(x)^(n+1)/(n+1) "appears" to converge to ln2. Only I don't think it does. Is it possible that they used the word "appears" because it is only that, it just appears to converge. Or is it impossible for a series to diverge around a certain number?

A_____________________B
100 km
Ok, you have two trains. One is starting to chu-chu from point A, and the other one from point B. Length of the rail is 100 km. First is going via speed of 40km/h, and the other is traveling via speed of 60 km/h. Now, you have a bird...The bird is flying from point A to point B, and when it reaches point B it flyies to point A, and so on...The bird is traveling with speed of 90km/h. The big question is...What is the distance that will the bird fly over, before the two trains colide?

I will graduate with a degree in engineering, the problem is that I did not do any interships and don't have any work experience. Also my academic performance is not the best.
I would appreciate any advice.
