11Which of these is the order for the electromagnetic spectrum? *Abbreviation (Ex: R=Radio waves)*
- AR-M-U-V-U-I-G
- BR-I-M-V-U-X-G
- CR-M-I-V-X-U-G

12How does the Doppler Effect help explain the Big Bang Theory?
- ABig Bang Theory says the universe is expanding. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
- BBig Bang Theory says the universe is shrinking. All light seen from earth is blue shift and has longer wave lengths meaning that the object sending the light is moving away from us.
- CBig Bang Theory says the universe is shrinking. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
- DBig Bang Theory says the universe is expanding. All light seen from earth is red shift and has longer wave lengths meaning that the object sending the light is moving away from us.
13An electromagnet is a magnet created when a circuit is closed, connecting a battery a wire and rapping it around an insulator.
- AVerdadero
