Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Answer:
True
Explanation:
This is true statement because in DC circuit there is only resistance which comes into play of opposition of current.
In DC circuit there is no role of frequency in if there is no frequency then there will no inductive reactance and no capacitive reactance to oppose the current flow
So in DC circuit only resistance is responsible to oppose the flow of current
So this is a true statement
