Yes, it is in the strong force that holds the nucleus together, but in general it cannot be released. Only very heavy and very light elements permit its release. Elements from Iron to Lead can't release any as these elements have the least of all.
Einstein showed that all matter is equivalent to energy, and deduced the equation E = mc2. However getting matter to give up this energy requires the right matter and the right conditions. We know there are two ways to obtain it, by fusion and by fission. Fusion is the way the stars produce energy, and this can be made to happen with light elements, isotopes of hydrogen are the easiest to activate. Fission happens with heavy elements like uranium and plutonium, and releases energy we can use in power plants.
No. Earth is an example of many things, such as an uneven rock with water in its low places, but earth is not energy, least of all nuclear.
No, not all energy is nuclear. Energy exists in many forms, such as electrical, chemical, thermal, kinetic, and potential energy. Nuclear energy is a specific type of energy generated from nuclear reactions in the nucleus of atoms.
All material uses nuclear energy.
All material uses nuclear energy.
All nuclear fuels contain radioactive elements.
All living things contain carbon. When they die and decompose, the decomposition process makes carbon rich fossil fuels, which can be used to produce energy.
All of them have nuclear weapons cause they are the United States.
Nuclear power is the major source of energy among all nations.
Saying nuclear energy is like saying Norwegian furniture. Nuclear power/energy is used everywhere, in 2009 20% of all electricity in the US was nuclear origin.
Yes all living things contain calcium
Yes, all stars release energy due to nuclear fusion.
