If a 150dB acoustic wave generator is placed in contact with a steel slab, determine the mand difference (Ap) within the slab given that the density of steel is 8050 kg/m and the speed of sou energy in the 5960 m/s. Assuming air has an acoustic impedance of 420 kg/(m-s), what percentage or acoustic wave will be reflected at the end of the slab? ap, determine the maximum pressure 2m and the speed of sound in steel is?

An acoustic signal is composed of the first three harmonics of a wave of fundamental frequency 425 Hz. If these harmonics are described, in order, by cosine waves with amplitudes of 0.630, 0.900, and 0.650, what is the total amplitude of the signal at time 0.825 seconds? Assume the waves have phase angles θn = 0.

One generator is placed in standby redundancy to the main generator. The faliure rate of each generator is estimated to be λ = 0.05/hr. Compute the reliability of the system for 10 hrs and its MTBF assuming that the sensing and switching device is 100% reliable. If the reliability of this device is only 80%, how are the results modified?

A loudspeaker is placed so that it is in contact with side-by-side regions of air, water, and iron, as shown in the diagram below. The loudspeaker is connected to a tone generator that is turned on and plays a note with a frequency of 200 Hz. In which material would the 200 Hz sound wave have the longest wavelength? In which would it be shortest? Using the simulator ‘Grayscale’ representation, shade in the boxes in the diagram above to show...

Two objects, A and B, at initial temperatures TA and TB are placed into thermal contact....

Two objects, A and B, at initial temperatures TA and TB are placed into thermal contact. If TA > TB, cA > cB, and mA > mB, why is the equilibrium temperature of both objects closer to TA than TB? a) Less heat flows out of object A than flows into object B, and so TA changes less than TB changes b) The same amount of heat flows out of A as flows into B, but it takes more heat...
