Jeremiah has drawn a diagram of a simple circuit. The circuit is made up a battery, a fan, wires, and a switch. Jeremiah wants to erase one of the parts he has now, and
draw a windmill in its place. Which part should the windmill be used to replace, and
why?

statement #3 on andre"s list is false.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
