A model would be useful for a scientist because it allows prediction of what may happen without doing really the experiments. It saves time and money for the scientist. Also, it helps scientists in communicating their <span>scientific investigation to people.</span>
The appropriate unit of measurement for pitch is mel.
Answer:
5.448 g/cm³
Explanation:
Density: This is defined as the ratio of the mass of a body to its volume.
The unit of density is kg/m³ other sub units are g/cm³, mg/mm³.
From the question,
D = m/πr²h......................... Equation 1
Where D = density, m = mass, r = radius, h = height.
Given: m = 9.58 g, r = 8/2 mm = 4 mm = 0.4 cm, h = 3.5 cm
Substitute this values into equation 1
D = 9.58/(3.14×0.4²×3.5)
D = 5.448 g/cm³
Hence the density of the metal rod is 5.448 g/cm³
