If Slovakia has a population of 5,400,000 and has a total fertility rate of 1.33 children per woman. How do I figure out what the population will be in 50 years? In order to sustain the population the fertility rate must be 2.05

this may be a stupid questions but when they call jupiter one of the gas giant planets,does this mean there is no solid core,and would'nt a planet made of gas not have as great a gravitational pull

Why put so much money into building new mansions for the government and research for such things as growing ears on poor mice, when we could be looking at other planets and maybe developing science fiction type things such as flying things and really fast aircraft and computers the size of rices grains?

It can be shown that the cross product of two vectors, A = Ax i + Ay j + Az k, and B = Bx i + By j + Bz k is as follows:
A * B = (AyBz - AzBy) i + (AzBx - AxBz) j + (AxBy - AyBx) k

The cross product can then be written as follows, where we use the rules for evaluating a determinant. (Note, however, that this is not actually a determinant, but a memory aid.)

| i j k |
A * B = | Ax Ay Az |
| Bx By Bz |

Assume that A = 7.2 i - 4.3 j and B = -8.5 i + 7.0 j + 2.0 k.

(a) Use the above results to determine the vector product A x B.
i + j + k
(b) Use the above results to determine the angle between A and B.

the unit in detamining the distance in space is astronomical unit ,i"m in doubt in this standard because astronomers they assume that the speed of ligth is constant,ist possible the dead stars,dwarf nebula dusty and may be others matters which are not well known there densities ,properties and other physical properties are equally penetrated by ligth with equl speed?

Did you know that hurricane Katrina dropped 49 inches of rain on land in one spot? Yup, right over the Yucatán Peninsula. Hmmm what does 49 inches of rain translate into when you use the 10 inches of snow for each inch of rain? 490 inches of snow. Hmmm, that would be FOURTY FEET, give or take a few inches. Heavier snow which is typical of the moisture rich snow thrown off by a Nor'easter might give us say THIRTY FEET. I don't mean to scare anybody about this. NYC would suffer the hurricane but Upstate New York, Pennsylvania, Massachusetts, lower Vermont and New Hampshire would receive the brunt of it all. They always do.

It's just a matter of time before the one that could produce that kind of weather pattern will manifest itself and sit on Long Island for a week, pumping all that moisture over the Northeast while dissolving the LI coastline. Just look at the shoreline. There are scallops up and down the coast all the way to Yucatán.
