Question

1. define density.
2. what is the formula for density?
3. what do each of the letters (d, m, v) stand for in the formula?

Explanation:

1. Density is a physical property that measures how much mass is contained within a given volume of a substance. It indicates how tightly packed the particles of a substance are.
2. The formula for density is \(D=\frac{m}{V}\), where \(D\) represents density, \(m\) represents mass, and \(V\) represents volume.
3. In the formula \(D = \frac{m}{V}\), \(D\) stands for density (a measure of mass per unit volume), \(m\) stands for mass (the amount of matter in an object), and \(V\) stands for volume (the amount of space an object occupies).

Answer:

1. Density is a physical property representing mass per unit volume of a substance.
2. The formula for density is \(D=\frac{m}{V}\).
3. \(D\) - density, \(m\) - mass, \(V\) - volume.
