Circular Motion
Describes how fast an object is rotating
What is angular velocity?
The term for the energy needed to heat an object by 1 degree
What is specific heat?
The two types of wave shapes
What are transverse and longitudinal?
The type of wave sound is
What is longitudinal OR mechanical?
A frequency of 440 and 465 are being produced. This is the beat frequency
What is 25 beats/second?
A force used to rotate an object
What is torque?
The formula for thermal expansion
What is: expansion coefficient X Length X Temp change
The time to complete a wave
What is a period
The term for the compression or expansion of waves from moving sources or observers
What is the doppler effect?
A 5000 cm material with an expansion rate of 0.0005 cm/degree is heated up by 350 degrees. What is the new length?
What is 5875 cm?
A hot and cold reservoir are parts of this type of machine
What is a heat engine?
The positive direction for torque
What is counterclockwise?
The three types of heat transfer
What is conduction, convection, and radiation?
This is the wave that repeats itself at regular intervals
What is a sine wave?
The type of pipe with all available harmonics
What are open pipes?
A material with a specific heat of 5.8 j/(g x C) heats up 44 degrees. If 5600 J of energy is added, this is the mass of the object
What is 21.9 grams?
The property of an object to resist a change in ANGULAR motion
What is moment of inertia?
This is the third law of thermodynamics
What is "we cannot achieve absolute 0"?
These are the 2 factors that affect a pendulum's time
What are gravity and length
Sounds below the human hearing range
What are infrasounds?
A pendulum with a length of 3 m is swung on earth. This is the length of the period
The spaced part of a longitudinal wave (opposite of a compression)
What is a rarefaction?
The point on an object where the object is balanced
What is center of mass?
Cooling caused by the expansion of a substance
This is the only factor that affects a wave's speed
What is medium?
The term for increasing and decreasing amplitudes from 2 different frequencies
What are beats?
A car produces a note with a frequency of 558 Hz. If it is moving towards an observer with a velocity of 85 m/s, this is the perceived frequency
What is 741.8 Hz?
