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.
The correct option is C.
During the summer period, the weather is hotter compare to the winter period because the sun is closer to the earth. The walls of our houses absorb the more intense heat and radiate part of it into the house, this makes us to feel warmer.
Answer:
Average speed = 1.2 m/s
Average velocity = 0.4 m/s
Explanation:
Average speed = total distance/total time
Average speed = (40 + 20)/(40 + 10)
Average speed = 60/50
Average speed = 1.2 m/s
Average velocity = displacement/time
Now, she ran 40 m south and ran 20 m back north which is in the direction of where she began the journey.
Thus;
Displacement = 40 - 20 = 20 m
Average velocity = 20/50 = 0.4 m/s
