Answer :
To determine which of the options is a typical measurement of mass, let's look at each one:
1. 2000 kg: This is a measurement in kilograms. Kilograms are a standard unit of mass used in the metric system. It's a common unit for measuring the mass of objects.
2. [tex]$1.989 \times 10^{30}$[/tex] miles per second: This expression represents a speed, as it uses units of miles and seconds. Speed measures distance over time, not mass, so this is not a measurement of mass.
3. 93 million light-years: A light-year is a unit of distance, representing how far light travels in one year. Distance measurements are not related to mass, so this option is not a measurement of mass.
Therefore, the option that represents a typical measurement of mass is 2000 kg.
