1)What is not true of a scientific law?
ipn [44]

A) It must be verified by scientists around the world.

A scientific law is a way to describe a phenomenon that occurs in our universe. In order for a research to become law, it must be accepcted by the vast majority - if not all - of the scientists in the same field. However, they do not have to verify the potential law, they can choose to falsify or just to accept proofs taken by the discovers.

---

A)It has been proven by several scientists independently, resulting in its being accepted as truth.

The Big bang is a scientific theory that explain how our universe was born. Before becoming a theory and becoming the "fact" we assume it is, it was long subject of study, and it was accepted only when different study from different scientists pointed out in the same direction. Hoever, ever today, study continues to have a better understanding of the phenomenon.

---

D)The results are considered more reliable because they were documented by separate investigations.

When different experiments are made, and they gave out similar results, the results become more reliable, as they are been proven by different sources in an indipendent way. However, this do not imply a pubblication or the trasformation of the results into a scientific law, as those steps go through a different process.

B)nuclear energy

C)electrical energy

D)thermal energy

Only mechanical energy is a type of kinetic energy. Kinetic energy means an energy that derives from a movement. Nuclear energy, electrical energy and thermal energy are other forms of energy. Energy from one of these sources could be converted into kinetic energy, or kinetic energy could be used to generate other forms of energy.
