since planets are revolving around sun with constant speed
and their orbit if fixed with constant variation
calculation shows that all planet moves with speed which only varies if any comet is passed by the planet

Okay, What I'm trying to ask is when a second is passed there's all these mili seconds and since the numbers are continous, there can be no 'another second' at all.
What is
'time' ?
the 'centuries'?
the 'years'?
the 'months'?
the 'weeks;?
the 'days'?
'hours'?
'minutes'?
'seconds'?
(and so on.)

Does all of that 'really' exists?

I personally think it isn't because it was being cooled in the ice water, causing the equilibrium to shift to the products (because it is releasing heat)

Many people/cultures over the world, over the last few thousand years, have stated the world will end,as we know it, in that time frame. Was on History channel (July 5th). It's even stated in the Bible.

Last 2 questions I hope which I need help on...

1. If you are dealing from a standard deck of 52 cards,

a) how many different 5-card hands could have at least one spade?
b) how many different 5-card hands could have at least two face cards (jacks, queens, or kings)


-------------------------

2. A theme park has a variety of rides. There are seven roller coasters, four water rides, and nine story rides. If Stephanie wants to try one of each type of ride, how many different combinantions of rides could she choose.

---------------------------------

Like the previous ones, I am not understanding these ones either... Can someone also provide tips on how to solve these combination questions..please...

sorry and thanks

what is y when x=1?

Decimal form should be okay

we all knows that atoms consist of the nucleus with the electrons orbiting it and between these particles there is empty space. now say we got 2 things each has their atoms lined up perfectly with their corresponding empty spaces relate to each others particles so if we then time it perfectly could we pass these 2 objects through each other?

After reading several pro-intelligent design books, I decided to try to find an unbiased source about this debate(the books were based on faulty logic and I was mainly wondering about the points they raised). Basically what are your views on evolution and can you back it up?

I'm working on a question that I really need some help with. It involves a relationship between the length in feet (l) of a column and the force in grams (f) it takes to buckle. The function is modelded as such: f = (k / l ^ 2)

I know that this is an inverse function becasue the function does not pass through the origin or the point (0,0). Here is what I need to know.... If k = 2000, I need to find the force needed to buckle the column of a length if 15 feet. Here is the function I have modeled and I hope it is correct:

f = (2000 / 15 ^ 2)

I have no idea how to solve this problem from here.

The next question is if the force required to buckle the column was 60 grams, I need to find the length of the column. I think the function looks like this...

60 = (2000 / l ^ 2)

Don't know where to go from here?

I really need some help and as soon as possible please. I will of course award 10 pts for best answer.
