Answer
  • True
  • False

Question 11

Question
Which of these is the order for the electromagnetic spectrum? *Abbreviation (Ex: R=Radio waves)*
Answer
  • R-M-U-V-U-I-G
  • R-I-M-V-U-X-G
  • R-M-I-V-X-U-G
  • R-M-I-V-U-X-G

Question 12

Question
How does the Doppler Effect help explain the Big Bang Theory?
Answer
  • Big 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.
  • Big 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.
  • Big 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.
  • Big 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.

Question 13

Question
An electromagnet is a magnet created when a circuit is closed, connecting a battery a wire and rapping it around an insulator.
Answer
  • True
  • False
