Question

1. density of a fluid

look at the graph.
what is shown in the graph?
a direct proportion

Explanation:

A direct proportion is a relationship where two quantities increase or decrease together at a constant rate. In a graph, this is represented by a straight - line passing through the origin. The given graph of mass vs. volume for a fluid is a straight - line passing through the origin (0,0). As the volume increases, the mass also increases. The formula for density is \(d=\frac{m}{V}\), and since the graph is a straight - line through the origin, the ratio \(\frac{m}{V}\) (density) is constant.

Answer:

a direct proportion
