considering Einstein's equation relating mass and energy, E mc2, which of the following statements is true? Mass can be turned into energy, but energy cannot be turned back into mass 8) it takes a large amount of mass to produce a small amount of energy. C) A small amount of mass can be turned into a large amount of energy D) You can make mass into energy if you can accelerate the mass to the speed of light E) One kilogram of mass represents 1 joule of energy 18. The long-term source of energy that powers the Sun is A) chemical potential energy of hydrogen burning into helium B) mass energy of hydrogen fusing into helium C) gravitational potential energy of the contraction of the gas cloud that formed the Sun D) kinetic energy of the orbital motion of the Sur. E) thermal energy of the hydrogen atoms in the Sun 19 IH an interstellar gas cloud shrank in size, what does the law of conservation of angular momentum predict will happen? It will A) heat up. B) slow down in its rotation. C) cool off continue shrinking. E) rotate faster 20 Where does the energy come from that your body uses to keep you alive? A) It is produced from the radiative energy of the Sun on your skin. B) It comes from the foods you eat. C) It comes from the water you drink D) It is in the air that you breathe. E) It is created during the time that you rest or sleep. 21 According to the umiversal low of provitation, the force due to gravity is A) directly proportional to the square of the distance between objects B) inversely proportional to the square of the distance between objects C) directly proportional to the distance between objects D) inversely proportional to the distance between objects. E) not dependent on the distance between objects. 22. The force of gravity is an inverse square law. This means that if you double the distance between two large masses the gr gravitational force between them A) also doubles B) strengthens by a factor of 4 C) weakens by a factor of 4. Dj weakens by a factor of 2 E) is unaffected. 23. As a comet passes by on its closest approach to the Sun, what can we say about how the sum of its has changed since it was at its maximum distance? potential and kinetic energ A) The sum has not changed. 8) The sum has decreased. C) The sum has increased. D) The sum is equal to the universal gravitational constant 24. Newton's version of Kepler's third law states: p2 GM M2) in this equation, what does G represent? A) the orbital period 8) the average distance between the two objects C) the masses of the two objects D) the universal gravitational constantExplanation / Answer
Note: according to chegg guide lines only one post is answered , other questions are repost seperately.

option C is correct.
the mass and energy relation is,
E = mc2
here, m is the mass and c is the speed of light.
the energy depnds on the mass. According to Einstein's theory, the small amount of mass is converted into large amount of energy. So, option C is correct.
