A, Lenz' Law. There need to be a difference of flux, so if you use AC you will get a current too.
It moves backwards do to the impact. this is because force can not be created nor destroyed so it is transferred.<span />

Answer:
The path of an object in uniform motion is a straight line.
Answer:
Conduction occurs more readily in solids and liquids, where the particles are closer to together, than in gases, where particles are further apart. ... As these molecules collide, thermal energy is transferred via conduction to the rest of the pan.
Explanation:
Metals have tightly packed atoms which can easily pass on their kinetic energy and also have free moving electrons.
