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

It is 6 g/cm3 because density cannot be negative, and it is not speed in which the unit would be m/s.

Answer 2

`density = 6 g/cm^3`

Step-by-step explanation:

as we know that density is the ratio of mass and volume of the object

`density = (mass)/(volume)`

here we know that mass as well as volume both are always positive so the ratio of both can not be negative.

so we know that mass is measured in gram and volume is measured in cubic cm

so the density is measured in

`density = (gram)/(cm^3)`

so the correct answer must be positive and in terms of above units

so we have

`density = 6 g/cm^3`
