Answer

Question:A beta particle has a relative mass of:42 0Answer:# Explanation:## Step 1A beta particle is a high-energy, high-speed electron or positron emitted by certain types of radioactive nuclei, such as potassium-40. ## Step 2The relative mass of a particle is a comparison of its mass to the mass of a proton or neutron. Protons and neutrons have a relative mass of approximately 1 atomic mass unit (amu).## Step 3Electrons, which are what beta particles are, have a much smaller mass compared to protons and neutrons. Specifically, the mass of an electron is approximately of a proton or neutron.## Step 4Given this, the relative mass of a beta particle (electron) is very close to 0 when compared to the mass of protons or neutrons.## Step 5Looking at the given options, the correct answer is 0, as it best represents the very small mass of a beta particle relative to protons and neutrons.# Answer: D
