Answer :
To determine which of the options is a typical measurement of mass, let's review each one:
1. 2000 kg: Kilograms (kg) is a standard unit used to measure mass. This is the correct unit for measuring mass as it directly represents the mass of an object.
2. 93 million light-years: Light-years is a unit of distance, not mass. It's used to measure astronomical distances, such as the distance between stars and galaxies.
3. [tex]$1.989 \times 10^{30}$[/tex] miles per second: This describes a speed or velocity, which is typically measured in units like meters per second or miles per second. It does not relate to mass.
4. 10 solar radii: A solar radius is a unit of distance used to express the size of stars in terms relative to our Sun's radius. It is not a measurement of mass.
Considering the standard units and definitions, the typical measurement of mass among the given options is 2000 kg.
