23592U is a naturally occurring radioisotope with a half-life of 7.1 x 108 yr. What percentage of this isotope that was present during the formation of Earth still remains? Assume that the Earth is 4.5 x 109 yr old and that no U-235 is created by decomposition of other elements.



a. 6.3%

b. 4.4%

c. 1.2%

d. 0.16%

e. 0.81%

I've worked through most of the math - k=8.76e-10
time = 4.5e9years - but how do I figure the percent remaining?

Correct me where I’m wrong plz.
Einstein said there is no such thing as absolute motion.

Inertia has the same value everywhere in the universe.

Does this suggest there could be a balanced ( 0 Force) background gravitational energy and the value could be calculated based on the amount of force necessary to accelerate mass. This must be considered using the concept that mass warps space and it’s the differential gravity forces we observe as gravity. Other words the presents of mass upsets the balanced gravity energy.

Is or could inertia be the result of the background gravity field?

On the subjetc of homosexuality: I am a Christian and have no problem with homosexuality at all:

Leviticus 18:22+Leviticus 20:13

These passages are the most explicit regarding the bible’s attitude towards homosexuality. They are ququoted time after time as being the reason Christians should condemn gay men and women or at the very least to encourage them to “heal themselves”.

But surely this is about context.

A sexual act involving two men was regarded as an "abomination" for the simple reason that it could not result in the pro-creation of children. Indeed, female homosexual acts were consequently not so seriously regarded, and are not mentioned at all in the Old Testament A tribe struggling to populate a country in which its people were outnumbered would value procreation highly but such values are rendered questionable in a world facing uncontrolled overpopulation.

what happened to imus was pretty devestating calling these girls on the basketball team ho's. I think prejutice is still with us more and more americans are getting violent and throw these racist comments. Do you think Rap is to blame, our generation feeds on rap culture, unlike past generations. I think more and more people in america are becoming racist in all accounts. Do you think this is only the beginning or do you think this will get worse????

We see that all living things in nature consume food. Then there are living creatures also at the fringes of organically recognisable life form; the bacteria living near hot waters vents by hydrogen sulphide deep on the seas bed where no other means of sustenance of life is available; then viruses that are semi alive, as they can stay dormant in crystalline form dead for years but reproduce like living organisms; my hair is not alive but it needs constant feeding.

If atom is the basic unite of matter then what energy source drives it as a mini solar system? And at a grander scale of things, what is the feed for the gravitational force present in all material objects?

What does religion say about this? In Quran, for example, Allah is the sole Creator of the universe who constantly nurtures and feeds all the worlds in existence. What is your personal stand on the matter: has God created a dead wilderness for us to be in, or a place both physically and conceptually very much alive?
