re:Your question was:
“WHAT is the average power of the detonation of a 1kg cube of TNT?â€</blockquoteâ€
I answered ~.0042GJ of energy; it took me about 2 seconds to move the decimal point to the left by 3 digits since you gave me the quantity of energy in a ton of TNT.
I obtained the equivalence of energy and power very long time ago from a book that was printed way before your were born, but since I did not trust my memory, I also looked it up on the internet.
It says that:If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts.</block quote>
I figure that if the formula works for a small quantity, then it must also work for a larger quantity.
Meaning that ~.0042GJ of energy = ~.0042GW of power.
If the following information is wrong, do not blame me, I only read it on the internet at this location: http://hyperphysics.phy-astr.gsu.edu/hbase/work.html
If you see that info as having a problem then write to the author of that web site.Energy
is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work. To do 100 joules of work, you must expend 100 joules of energy.
Power
is the rate of doing work or the rate of using energy, which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts.
Work-Energy Principle
Wnet=1/2mv2final - 1/2mv2initial
The change in the kinetic energy of an object is equal to the net work done on the object.
This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. It is derivable from conservation of energy and the application of the relationships for work and energy, so it is not independent of the conservation laws. It is in fact a specific application of conservation of energy. However, there are so many mechanical problems which are solved efficiently by applying this principle that it merits separate attention as a working principle.
But all this brings me no closer to understanding your view point on the efficiency of nuclear power plants.
If you have a problem understanding the E=(U/K)C formula then ask me to explain it, I understand it very well, because I created (or discovered) it.
