Question

John and Linda are arguing about the definition of density. John says the density of an object is proportional to itsmass. Linda says the object's mass is proportional to its density and to its volume. Which one, if either, is correct?A. They are both wrong B. John is correct, but Linda is wrong C. John is wrong, but Linda is correct D. They are both correct. E. They are free to refine as they wish.

Answer 1

We will have that:

$\rho=\frac{m}{V}$

So, we can see that density is directly proportional to the mass.

And the mass is directly proportional to density and volume.

So they are both correct.
