Explanation:
Draw a labeled sketch of an electric motor to show how it uses electromagnetism to convert electrical energy to kinetic energy.
Assume that an electromagnet and a solenoid have the same number of turns in their wire coil and the same amount of current flowing through the wire. Which device has the stronger magnetic field? Explain your answer.

Explanation:
Describe how sound waves travel through a solid, liquid, and gas. Why does it move differently through these different mediums?
Answer:
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
hope this helps.
