Answer the following question given this paragraph: Einstein's equation helps scientists understand what happens in nuclear reactions and why they produce so much energy. When the nucleus of a radioisotope undergoes fission or fusion in a nuclear reaction, it loses a tiny amount of mass. What happens to the lost mass? It isn't really lost at all. It is converted to energy. How much energy? E = mc 2 . The change in mass is tiny, but it results in a great deal of energy. Q: Einstein's equation helps scientists understand what happens in nuclear reactions and why they produce so much what? Choices: - light - food - hydrogen - energy A:
(Answer)
energy

Answer the following question given this paragraph: The strength of an acid depends on how many hydrogen ions it produces when it dissolves in water. A stronger acid produces more hydrogen ions than a weaker acid. For example, sulfuric acid (H 2 SO 4 ), which is found in car batteries, is a strong acid because nearly all of it breaks down into ions when it dissolves in water. On the other hand, acetic acid (CH 3 CO 2 H), which is the acid in vinegar, is a weak acid because less than 1 percent of it breaks down into ions in water. Q: The strength of an acid depends on how many of which ions it produces when it dissolves in water? Choices: - silicon - carbon - helium - hydrogen A:
(A).
hydrogen
Ques:Answer the following question given this paragraph: Figure 6.6 Water behind a dam has potential energy. Moving water, such as in a waterfall or a rapidly flowing river, has kinetic energy.

Q: Water behind a dam has potential energy. moving water, such as in a waterfall or a rapidly flowing river, has this? Choices: - residual energy - thermal energy - compression energy - kinetic energy A:

Ans:kinetic energy
