Janice measured the mass and the volume of an object. She then determined the density of the object by dividing the object's mass by its volume \([tex]D=\frac{m}{v}[/tex]).

Which value would most likely represent the density of the object?

A. [tex]-1 \, \text{g/cm}^3[/tex]
B. [tex]4 \, \text{m/s}[/tex]
C. [tex]-3 \, \text{m/s}[/tex]
D. [tex]6 \, \text{g/cm}^3[/tex]



Answer :

To determine which value most likely represents the density of the object, we need to analyze the given values and their units of measurement. Density is defined as mass divided by volume and is typically measured in units of mass per unit volume, such as grams per cubic centimeter (g/cm³).

Let's review the given values:

1. [tex]\(-1 \, g/cm^3\)[/tex]: This value has the correct units (g/cm³) for density. However, density, being a physical quantity that represents mass per volume, should not be negative. Therefore, [tex]\(-1 \, g/cm^3\)[/tex] is not a viable option.

2. [tex]\(4 \, m/s\)[/tex]: This value represents a speed, measured in meters per second. Speed is not related to density and does not have the correct units. Therefore, [tex]\(4 \, m/s\)[/tex] cannot represent the density of an object.

3. [tex]\(-3 \, m/s\)[/tex]: Similar to the second option, this value represents a speed, measured in meters per second. This is not relevant to density and does not have the correct units. Therefore, [tex]\(-3 \, m/s\)[/tex] cannot represent the density of an object.

4. [tex]\(6 \, g/cm^3\)[/tex]: This value has the correct units (g/cm³) for density. It is a positive value, which makes sense for the physical quantity of density. Therefore, [tex]\(6 \, g/cm^3\)[/tex] is a viable and most likely correct option for representing the density of the object.

In conclusion, the value that most likely represents the density of the object is [tex]\(6 \, g/cm^3\)[/tex].
