The correct answer is D. All of these are its properties.
Cosmic rays are high-energy particles that travel through space at nearly the speed of light. They are mostly protons, but also include electrons, neutrons, and heavier atomic nuclei. Cosmic rays are thought to be produced by supernova explosions and other energetic events in space.
The main properties of cosmic ray particles are their electric charge, rest mass, and energy. The electric charge of a cosmic ray particle determines its interaction with other particles. The rest mass of a cosmic ray particle determines its inertia. The energy of a cosmic ray particle determines its ability to penetrate matter.
Cosmic rays are a valuable tool for studying the universe. They can be used to study the composition of the interstellar medium, the structure of the Milky Way galaxy, and the nature of dark matter. Cosmic rays can also be used to study the Earth’s atmosphere and the effects of radiation on living things.
