B
Most simple machines are electric and do not use energy.
C
Simple machines run from computers and do not require energy.
D
Simple machines use energy transfer and friction reduction to make work easier.
5) A glass bottle has 500 ml of water and is capped and put over a lit candle. The molecules heat and move quickly. If the bottle is left over the heat for a long time what happens?
A
The water will boil and slowly disappear.
