Question

as the angle of impact increases, the length of the spatter ____________. increases decreases remains the same there is no way to determine it

Explanation:

The length of spatter is related to the angle of impact. When the angle of impact increases (approaching 90 degrees, a more perpendicular impact), the spatter becomes more circular (less elongated). The formula for the angle of impact \(\theta=\sin^{- 1}(\frac{width}{length})\). As \(\theta\) increases (for a given width, assuming width is relatively constant in some scenarios like same - type of spatter source), the length \(length=\frac{width}{\sin\theta}\) decreases. For example, if \(\theta = 30^{\circ}\), \(\sin\theta=\frac{1}{2}\), and if \(\theta = 60^{\circ}\), \(\sin\theta=\frac{\sqrt{3}}{2}\approx0.866\). If width \(w = 1\), then \(length_1=\frac{1}{0.5}=2\) and \(length_2=\frac{1}{0.866}\approx1.15\).

Answer:

B. decreases
