5. What is the definition of energy and unit it is measured in?

6. Energy is the ability to do work, measured in Joules.

7. What is constructive and destructive interference in relationship to waves being in and out of phase.

8. Constructive- in phase, waves add Destructive- out of phase and waves cancel

9. What are the names of 2 different types of Potential Energy

10. Gravitational Potential energy And Elastic potential energy

11. What are the 5 forms energy can be found in?

12. 1.Chemical 2.Nuclear 3.Mechanical 4.Heat 5.Electromagnetic

13. What is the Doppler Effect and describe its effect on light and sound.

14. Doppler Effect- change in frequency as waves travel towards/away Light- Blue:towards; Red: away Sound- High pitch: towards; Low pitch: away

15. What is the difference between harmonic and linear motion and give an example of each.

16. Harmonic motion is repeating- like a swing going back and forth, or like Dr. B in class saying the same things over, and over, and over again. Linear motion does not repeat, like walking home from a concert after the taxi never showed up

17. Direct or Inverse??? What is the relationship between -frequency and wavelength -wavelength and period -period and frequency

18. -frequency and wavelength: inverse -wavelength and period: direct -period and frequency: inverse

19. Draw a wave and label: Crest, trough, amplitude, and wavelength

21. What is the difference between mechanical and electromagnetic waves and give an example of each.

22. Mechanical- requires a medium (sound) Electromagnetic- no medium required (light)

23. When singing in the shower, Dr. B hit a note that cracked her bathroom mirror. What is the name of this phenomena and describe in detail how it works. In your description discuss how sound waves travel (transverse/longitudinal- compressional/mechanical/electromagnetic/) and how they interact (constructive/destructive interference).

24. This phenomena is called resonance. Sound waves are mechanical (require medium) and longitudinal/compressional (wave travels in the same direction as motion). When the frequency of the pitch of Dr. B’s amazing operatics equals the natural frequency of the glass, constructive interference happens and the amplitudes increases so much that the mirror breaks.

25. What is the difference between a star and a planet?

26. Stars undergo nuclear fusion and planets do not.

27. Direct or Inverse?? What is the relationship between -Gravity and mass -Mass and Lifespan

28. Gravity and mass- direct Mass and lifespan- inverse

29. If a white dwarf and a neutron star got into a confrontation, who have more pull on the other? Describe why.

30. Neutron star because it is more dense and more mass, more gravitational pull.

31. What is more luminous, a Blue supergiant or a Red giant? Explain.

32. Blue supergiant. Luminosity is brightness. Blue light is a higher frequency (more energy) and brighter than red light.

33. When black holes engulf objects, X-rays get emitted. Explain why this would make sense using E=mc2 and the law of conservation of mass/energy.

34. The law of conservation of … states that energy/mass cannot be created nor destroyed but can only change forms. Einstein’s equation E=mc2 states that energy and matter can be converted into each other as well. So when matter gets sucked into a black hole, the intensity of the pressure can change mass into energy, which is being emitted.

35. What is the name of the crust and outer mantle combined?

36. lithosphere

37. What is the name of the circular motion of the fluid that moves the plates and where is it located in the Earth’s structure (one word)?

38. Convection currents in the Asthenosphere

39. What are the layers of the Earth and their respective states of matter?

40. Inner core- solid Outer core- liquid Inner mantle- liquid Outer mantle- solid Crust- solid

41. What kind of boundary causes mountains, trenches, and volcanos and specify the nature of each.

42. Convergent boundaries of: Continent- continent- mountains Continent- ocean- volcano Ocean- ocean- trench

43. What are the 3 types of boundaries and what tectonic feature/movement does it produce?

44. Transform- earthquake Divergent- valley Convergent- mountains/volcano/trench

45. What word does Dr. B use (repeated harmonicly) to indicate that you should kindly put away your computers?

46. Rid, rid, rid….

47. Fill in the blank: Despite it all, to me she was beautiful still, but that beauty had faded, glowing like a _______ _________who had reached almost the end of her life, like a dying white rose past its prime.”

48. White dwarf

49. What uses more gass, a honda civic or a hummer and what does this have to do with the universe?

50. A hummer. Because bigger stars use a lot more fuel (and therefore have shorter lives).

51. Why are some of you like a black hole?

52. Because the information goes in but never comes out. Where it goes is a mystery.

53. What is not matter, but does matter?

54. Energy

55. Make your wager

56. What is the strongest force in the universe?

57. Love.
