Question

question 11
take a look at this sketch, and then answer the questions below about the mass, volume and density of objects d and c.
which object has
the greater mass?
which object has
the greater volume?
which object has
the greater density?

Explanation:

Step1: Determine mass

A balance scale shows mass equality when balanced. So, mass of \(D\) and \(C\) is same.

Step2: Determine volume

From visual inspection (size of cylinders), \(C\) has larger volume.

Step3: Determine density

Density formula \(
ho=\frac{m}{V}\). Since \(m_D = m_C\) and \(V_C>V_D\), then \(
ho_D>
ho_C\) (as density is inversely proportional to volume when mass is constant).

Answer:

Which object has the greater mass? neither (they are the same)
Which object has the greater volume? \(C\)
Which object has the greater density? \(D\)
