Exam 3 T/F Flashcards
The larger the tension you apply to a string the slower the waves
travel along the string.
F
The wave number is proportional to the inverse of the
wavelength
T
Fourier analysis can generate square waves from sine waves.
T
The nodes of a standing wave have zero amplitude.
T
Atmospheric pressure is equal to 101.3 Pa.
F
Atmospheric pressure is the weigh of the air above a meter square
area at sea level.
T
Oscillatory motion only applies to sine or cosine functions.
F
The small angle approximation applies to angles between 0 and
60 degrees.
False, angles less than 10 degrees
The kinetic energy of a pendulum is largest when it is at its lowest
swing height.
True
The Tacoma Narrows Bridge failed because a moderate wind was
able to force the structure at its resonance frequency.
T
The peak in a potential energy graph is the most stable location.
false
Statics applies Newton’s 1st Law to both linear forces and rotational torques.
true
In a uniform gravitational field a body’s center of mass is located
at the same location as its center of gravity.
true
