As frequency increase,
Reactance due to mass increases, reactance due to stiffness decreases
The frequency of free vibration is also called resonant or natural frequency
True
Mass reactance is greater at high frequencies
True
Stiffness reactance is greater at lower frequencies
False
resonant frequency
Masss and stiffness reactance cancel each other, oppositions to vibration comes from resistance component
Air and water have the same impendence
False
Rate at which work is done
Power
True statement
Harder to get massive object to vibrate quickly, harder to get stuff objects to vibrate slowly
Bandpass filtet had ___ cutoff frequencies
2
Vey small portion of energy is transmitted if the impendence mismatch is large
True
Filter which is used to elimate just one frequency is called
Notch filter
Type of filters have 2 cutoff frequencies
Bandpass and band stoppn
True statement for tube open both ends
Antipode form at both ends
Time period of a complex t periodic wave is equal to
The time period of the fundamental frequencies
In a open tube at one end
Only off harmonics can be produced
Tube length and fundamental frequency are inversely proportional to each other
True
Three pure tone - 6 hz, 4 hz, 3hz, 1 m tied both ends,
Lowest natural resonant frequency is 6hz
Tube open at both ends can resonate at odd and even harmonics
True
