Answer:
I believe the answer is B) Two wavelengths
It takes work to push charge through a change of potential.
There's no change of potential along an equipotential path,
so that path doesn't require any work.
Answer:
Explanation:
F = ma
a = F/m
a = (200.0 + 150.0 - 100.0) / 91.0
a = 250.0/91.0
a = 2.7472527...
a = 2.75 m/s²
Answer:
2k
Explanation:
100W X 10h = 1000Wh = 1KWh thus cost is 2k
