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.
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. There are many types of energy, such as solar and kinetic.
All material uses nuclear energy.
All material uses nuclear energy.
All nuclear fuels contain radioactive elements.
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.
Nuclear power is the major source of energy among all nations.
Nuclear Energy is able to produce a constant ammount of energy at all times where as solar energy does not.
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.
Heat is the vibration of the atoms or molecules that make up things. As all atoms can vibrate and all objects are made of atoms, all objects contain heat energy.
The sun, like all stars, gets its energy from nuclear fusion. The Earth is only habitable for life because of the sun's radiant energy which reaches us. So we all depend on nuclear energy.
All of them have nuclear weapons cause they are the United States.
