I mean does it do any good-- balance anything out? Hypothetically speaking, Would not having it, greatly effect things in nature(like having no moon would)? or is it just there to zap stupid people off the earth?

I recently read a book, titled, "Jupiter, The Star That Failed" by
Joel N. Shurkin. In the book, I believe the author stated that Jupiter would need about 100 times its current mass to have enough gravity to create the internal pressure which would cause the temperature to rise to the 20 million degrees necessary for fusion to begin. And thus shine like a star. The cube root of 100 times its current diameter is 4.64*88,865 = 412,000 miles. This is very rough I know but my question are:

1. Can Jupiter continue to accumulate hydrogen over a few million years and eventually reach this point??

2. Can the process described above be considered the way stars do come to be?? In other words can Jupiter be considered to be a "pre-star"?

3. Why aren't all stars the same size? Seems they would all hit the mass requirement for fusion & be the same size?

4. Can stars grow after fusion begins?

or this 5. Good beginners book on star formation?

Two main things generally determine whether a bond is polar or nonpolar. One is the electronegativity of the elements, the other is the geometric shape of the molecules formed. How do we determine the geometric shape? For example, if you have three atoms, it can either be linear, like H-Be-H, or bent, like H/O\H. If it's linear, there's a good chance of it being, nonpolar, if it's bent, it's probably polar. So it's important. Or you could have 4 atoms, and they could either be Planar, Triangular, or Pyramidal. What determines which geometric shape it is?

If i wish to place 2 bets......of which only one can win.....

1 at a probable payout of $2.25, and the other at a probable payout of $2.95

How much do I have to bet on each of these so that the one winner (which will eliminate the other) will give me a profit of $100.00 AFTER covering the cost of both bets?

What is the formula for figuring this out?

What type betting calculator can compute this?

Thank you.
