Question

Janice has just measured the density of an object. Which value is possible? (Density: D = )

–1 g/cm3
4 m/s
–3 m/s
6 g/cm3

Answer 1

By definition, the density of an object is given by:

`image`

Where,

M: mass of the object

V: volume of the object

Since the mass and volume of an object are numerical values greater than zero, then it follows that:

`image`

It is important to respect the units of each measure.

For this case we can use the grams for the mass and cubic centimeters for the volume.

Answer:

A possible value for density is given by:

`6 (g)/(cm^3)`
