35
An example of a longitudinal wave is a _________ wave.
36
Classrooms with carpet are quieter than classrooms with tile because the sound waves are __________.
37
Gravity on the moon is about 1/6 th the gravity felt on earth, this is because…?
39
The distance from the rest line to the crest is called...?
40

41
What is a sound wave?
42
What is absorbed?
43
The moon is much less massive that the earth.
44

45
Electric companies usually sell electrical energy in units of… a.Watts b.Amperes c.Volts d.Kilowatt-hours
46
These kinds of circuits are less expensive to make and have one path or branch
48

49
Can objects be charged by moving protons from one object to another?
50
Explain how grounding can offer protection from electric disharges.
51
What is kilo-watt hours?
52
What is a series circuit?
53
Parallel circuits because if one circuit goes out the rest of the circuits will keep working
54
No, proton are held tightly with neutrons in the nucleus of an atom.
55
Grounding causes excess charge to drain into the earth which can absorb the excess charge.
