What is the energy loss of a charged particle in matter when it travels through a material with a given atomic number and density, assuming it has a particular energy and charge? Use the Bethe-Bloch formula to calculate the energy loss and explain how the formula takes into account various physical factors such as the target atom's atomic number, the incident particle's velocity, and the Coulomb force between the charged particle and the electrons in the material. Finally, compare and contrast the energy loss for different materials using the Bethe-Bloch formula.
