Question

Which statement correctly describes mass-energy equivalence?

A) All energy in the universe will be converted to an equivalent amount of mass.
B) Mass can decrease in nuclear changes without the production of energy.
C) All energy in the universe is a result of mass being converted into energy.
D) A large amount of mass is equivalent to a small amount of energy.

Answer 1

The answer is option C

Answer 2

Answer:

The correct option is C. The statement which correctly describes the mass-energy equivalence is all energy in the universe is a result of mass being converted into energy.

Explanation:

• As a result of Einstein's theory of special relativity, mass and energy are equal which merely indicates that energy can be changed into mass and vice versa.
• This equivalency states that mass and energy can be converted into one another. Therefore, having mass indicates that you have a lot of energy stored inside.
• This is stated in Einstein's well-known relationship.
• E=mc² where, E = Energy, m = the mass in kilogrammes and c = the speed of light in a vacuum where c ≅3×108 m/s.
• According to the formula, even if energy plays no role in the formation of matter, a small amount of it has the appearance of a huge amount of it at rest.
• Almost all the energy in the universe is a result of mass being converted into energy.

Thus, the statement which correctly describes the mass-energy equivalence is all energy in the universe is a result of mass being converted into energy.
