200
What is static electricity?
When two bodies have an opposite charge and electrons quickly travel to the other to equalize, causing a shock
300
What are mechanical waves?
Waves that REQUIRE a medium to travel through
300
Would a Low Frequency sound have a low pitch or high pitch?

400
What type of circuit is on the left
Parallel circuit
500
What is the difference between a transverse and a compression wave?
Transverse the oscillation is perpendicular to the flow of energy whereas compression is the same direction
500
