Answer:
C. The voltage drop across the resistor is 2.1V and nothing about the current through the resistor.
Explanation:
When connected in parallel, voltage across the resistances are the same. So if 2.1V was dropped across the LED then 2.1V was also dropped across the resistor. However, this tells us nothing about the current through the resistor. We can find the current across the resistor if we know the resistance of the resistor, but that's about it.
If it were a series connection, then the current would have been the same, but the voltage drop were another story.

Answer:
The loudness of sound is most closely related to
The pressure within a sound wave determines the loudness of the sound. In this lesson, learn how to calculate the sound pressure level of a sound wave and what this measurement represents.
Explanation:
Explanation:
Given:
v₀ = 15 m/s
a = 3.5 m/s²
t = 5.0 s
Find: v
v = at + v₀
v = (3.5 m/s²) (5.0 s) + 15 m/s
v = 32.5 m/s
