Transverse standing waves with a period of 4.0 x 10^-4 s move along a string with a velocity of 840 m/s. a) what is the wavelength of these waves? b) if the frequency associated with the wave in part a corresponds to the fourth overtone, how long is the string?

Which type of wave can travel without a medium

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
