The correct answer is D
According to the law of conservation of mass, mass can not be destroyed or lost, it can just be rearranged in space, turned into energy etc.
Therefore, in our of example the wood was burned and turned into ashes. Even though the ashes weight less than the original wood, some of the solid mass of the wood was converted to gas and energy, so the overall mass remained the same.
The two roots of this functions are the exact roots and one is an imaginary root. The -2 is the root of a negative number -16 because if you compute the -2 on its 3rd power you come up -16, the 2 is the root of 16 and the 4+i contains a imaginary number that is why it is an imaginary root

Answer:
The statement that describes the advantage of a nonrenewable energy source is that ' they are currently found in abundance' Option D.
Explanation:
Nonrenewable energy sources are sources of energy which will not be replenished after their use, their production usually takes millions of years to be accomplished, Like crude oil, the synthesis under the ground was believed to take Millenium from the various geothermic reactions that occur on the buried biomass millions of years ago.
However, since these energy sources are liable to be exhausted quickly due to their unreplenish nature, nature provides them in abundance. They are currently found in large quantity. Take for example, the coal deposit and crude oil wells which had been mined for many years before now. The continuous usage of these nonrenewable sources nevertheless makes them to be susceptible to exhaustion in some years to come.
