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.
Errrrr, it has 80.
80 is the correct answer
Answer:
light is an example of a wave that is not mechanical .
it is different as it does not need material medium for its propagation
Answer:
B - Velocity
Explanation:
Velocity definition: “The speed of something in a given direction.”
