Wave and tidal energy projects are possible because of the law of conservation of energy. would they still be possible if the ocean were an isolated system? explain your answer in terms of how matter and energy are exchanged in systems.

Explanation:

Isolated system is the system which does not come into contact with it's surrounding environment, therefore, the energy and matter within the system remains constant. For example, hot tea in the insulated container and closed.

So, if the ocean were an isolated system then these projects were not possible because as I explained above that in an isolated system the exchange of energy and matter does not take place and these projects are possible due to the Law of conservation of Energy.

answer; i believe its (ovulation);

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
