Here are the answers to the questions: 1. D. electrons. Beta particles are high-energy electrons (or positrons) emitted from the nucleus of an atom during radioactive beta decay. 2. B. one million times. Assuming "m" refers to "millimetre" (mm), we can convert units: Step 1: Convert kilometres to metres. 1 kilometre = 1000 metres Step 2: Convert metres to millimetres. 1 metre = 1000 millimetres Step 3: Calculate the total conversion from kilometres to millimetres. 1 kilometre = 1000 metres × 1000 millimetresmetre = 1,000,000 millimetres Therefore, a kilometre is one million times larger than a millimetre.
