What is thermal equlibrium?
No net heat flow
Which waves need a medium?
Longitudinal
What does a generator do?
Convert mechanical energy into electrical
Impulse is?
The change in momentum
Define harmonic motion
Motion that repeats over and over again
The highest point of a wave is called a?

For an electromagnet if you add more coils does the power increase, decrease or stay the same
Increase
What is momentum?
Mass in movement
What is the Zeroth law of thermodynamics?
If 2 systems are are in thermal equlibrium with a third system then those 2 are in equlibrium with eachother.
Constructive interference is what?
When 2 waves zero out and form a larger wave
What does Coulomb's law describe?
How the charge between the center of 2 objects determines the amount of electrical force.
