Closed is the correct answer :)
The answer is A because potential energy is stored up energy which means that it’s not moving
The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.
A mirror only mists because the air is hot and the mirror is cold and if it is heated than the steam wont make the mirror become misty....
hope this helps :D
125 kmph
250=2
X=1
250/2= 125
