In a pipe closed at one end and filled with air, a 384-Hz tuning fork resonates when the pipe is 22-cm-long; this tuning fork
does not resonate for any smaller pipes.
(a) State three other lengths at which this pipe will resonate with the 384-Hz tuning fork. Explain / show your
reasoning

What is the scientific definition of energy that relates to work

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

What is the rate of change in a objects position?
