The main concern about Nuclear Power is Waste Managment.
But Nuclear Materials ALREADY EXIST in nature.
Assuming that:

Uranium is the main Fuel of Nuclear Reactors
and
Plutonium is the main Waste of Nuclear Reactors

If: Uranium Half Life << Plutonium Half Life.

What is safer for the environment?
to have ore Uranium or Stored Plutonium?

What is more environmentaly safe?

Considering that Uranium already exists in nature and that
its half life is much much longer than Plutonium

I know that everyone is different and that its all a matter of opinion but why should I think that the music I write sounds so good, whereas most other people my think its rubbish or just ok at best? Also do you think that there is at least 1 person in the world who would like my music as much as or even more than myself, even though the vast majority think its rubbish?

This question is not about wheather or not the music i write is good or not, for that is just a matter of opinion, it is more about the mental side of why we like music.

Im not sure if this question makes much sense at all, if it doesnt make any sense to you feel free not to answer

I have made a tentative ID as a modern Southdown.

These sheep are not on the original wild downs. They were on the
richer Adur valley (the levels), which probably has a layer of
alluvium over the chalk bedrock. Sussex, England.

Thanks for the other sheep replies earlier.

how do i find the concurrent forces of the ff:
given: F(sub 1)= 5 Newton,north; F(sub 2) 7 N at 30degreeof W; F(sub 3)= 10 N at 75 degree W of S

determine:1. F(sub 1) +F(sub 2) 2. F(sub 2)- F(sub 3) 3. F(sub3)+F(sub1)-F(sub 2)

what will i do...i dont know if its only a ordinary addition or substraction???please kindly help me with this

When glass bowl is dropped onto a hard surface, if often bounces a few times before it finally smashes. As the kenetic energy of the bowl is much reduced on each bounce, this seems counter intuitive. (and quite disappointing when you are raising your hopes that it will survive). If I were to catch the bowl the bounce before it finally smashed (assuming I knew which bounce that would be), would I notice any visible damage? If not, would be bowl be in an invisibly weakened state?

I will vote for the best answer here....tnx.

1. A semiconductor manufacturer seeks to maximize its profits. Testing indicates that they can produce 100,000 chips per week at a cost of $40 per chip, and sell them for $65 per chip. They also find that they can produce 125,000 chips per week at a cost of $35 per chip, and sell them for $63 per chip. How much profit can they expect to earn if they produce 130,000 chips per week?

according to quantum physic anything can happen in the universe so long as it is for a short enough time. for example a positron and a electron will spontaniously exist and then concel each other out. momentarily breaking the conservation of mass/energy law. but how long are we talking about in second for this to happen?
