(a)What are these diagrams called?
(b)How efficient is each light bulb?
(c)Which is the energy-saving light bulb and which is the filament bulb?
Friction between the moving parts causes heating
Use wider wires!
The resistance of the wire causes it to get hot when current passes through
Key Question: How can we improve the efficiency of Wall E?
Air resistance causes energy to be lost to the surroundings
Sound created when Wall E moves
It heats up the surroundings, and spreads further and further away from the source.
Industry tries to capture and use heat. still loses heat to the surroundings.
