Question

Which of the following is an example of baryonic matter?

A) you
B) the particles produced by physicists in particle accelerators
C) electrons and positrons produced by pair production
D) WIMPs
E) neutrinos

Answer 1

The example of baryonic matter given in the options is A) you, as baryonic matter consists of particles made up of three quarks, such as protons and neutrons.

Step-by-step explanation:

An example of baryonic matter from the options given would be A) you. Baryonic matter is any matter that is composed of baryons, which are subatomic particles made up of three quarks; this includes protons and neutrons, the building blocks of the atoms that make up our bodies. Thus, humans, and indeed all normal matter that we can observe in the universe that is composed of atoms, are made of baryonic matter. The other options given, such as particles from accelerators (B), electrons and positrons (C), WIMPs (D), and neutrinos (E), do not fit this definition as they are not composed of baryons. For instance, WIMPs are hypothetical non-baryonic particles thought to account for dark matter, while neutrinos are leptons, another type of elementary particles.
