Which of the following values would most likely represent the density of an object?

• A. -3 m/s
• B. 6 g/cm^3
• C. -1 g/cm^3
• D. 4 m/s

Answer: (B)

Verified step by step guidance

1. Understand that density is defined as mass per unit volume, so its units are typically expressed as mass divided by volume, such as grams per cubic centimeter (g/cm^3) or kilograms per cubic meter (kg/m^3).
2. Identify the units given in the options: '-3 m/s' and '4 m/s' have units of velocity (meters per second), which are not appropriate for density.
3. Look at the options with units of mass per volume: '6 g/cm^3' and '-1 g/cm^3'. Both have the correct units for density, but density cannot be negative because mass and volume are always positive quantities.
4. Eliminate '-1 g/cm^3' because a negative density is physically impossible.
5. Conclude that '6 g/cm^3' is the most reasonable value representing the density of an object because it has the correct units and a positive value.
