13. B
14. C
17. idk
18. C
54. idk
55. True (not positive)

Answer 8

13. is B because apparent magnitude is a stars brightness from earth, but absolute magnitude is brightness in standard distance.

Answer 9

54 - low voltage means less force moving the electrons so false

55 - parallel means multiple paths for the circuit so the circuit might still work if one path is broken.
