Science is my worst subject... 1. Jacki's friend claims that future improvements in engine design will allow vehicles to travel any distance engineers want on just 1L of gasoline. 2. For an electric toothbrush, is input energy equal to useful output energy? 3. Which of the following would not produce more electricty when a magnet is moved back and forth through a coil of wire. 4. Moving a magnet through a coil of wires converts ___________ energy into ___________ energy. 5a. Complete the following. ___________ -> Generator -> ___________ b. Name the converter in the above system. -------------

1. No, there is a physical limit to fuel consumption effeciency 2. no imput(batteries) is always > output the batteries, you can't have a 100% efficenctcy on any known system 3.D 4 m,echanical , electric
// just a guess on 5 power, generator,work

Jacki's friend claims that future improvements in engine design will allow vehicles to travel any distance engineers want on just 1L of gasoline. Is Jacki's friend correct? Why or Why not? ________________________________________________ ________________________________________________ ________________________________________________ -------------

i thought energy -> generator -> electrical energy
like how a windmill converts wind to electricity, and how waterdam-things work ------------- ▄▄█ ▄▄█ ▄█▄ ▄█▄ |
