Answer :
When we're looking at typical measurements of mass, we need to focus on units that are commonly used for weighing or measuring how much matter is in an object. Let's review each of the given options:
1. 2000 kg: Kilograms (kg) are a standard unit for measuring mass. This is a typical and common way to express mass, especially for heavier objects or in scientific contexts.
2. 93 million light-years: A light-year is a unit of distance, not mass. It measures how far light travels in one year. Therefore, this is not used to measure mass.
3. [tex]$1.989 \times 10^{30}$[/tex] miles per second: Here, "miles per second" indicates a speed or velocity, not mass. This is not a typical measurement of mass.
4. 10 solar radii: A solar radius is a unit of distance that measures how far across the sun is from its center to its surface. This is not a measurement of mass.
After analyzing these options, "2000 kg" is the correct choice since it's the only one that represents a typical measurement of mass.
