Question

an elongated drop of blood was found with a width of 2.5 mm and a length of 5.0 mm. at what angle did the blood drop hit the surface? sin θ = w / l angle θ sin θ 0 0 30 0.5 60 0.87 90 1 30° 60° 90° 0°

Explanation:

Step1: Identify values of w and l

$w = 2.5$ mm, $l = 5.0$ mm

Step2: Calculate sin θ

$\sin\theta=\frac{w}{l}=\frac{2.5}{5.0}= 0.5$

Step3: Find the angle θ

From the table, when $\sin\theta = 0.5$, $\theta = 30^{\circ}$

Answer:

$30^{\circ}$
