A thermal engine operates using an ideal gas that’s contained within a movable piston. During one complete cycle, the gas goes through an isobaric transformation followed by an adiabatic transformation. Given that the pressure stays constant during the isobaric transformation and that there’s no heat exchange in the adiabatic transformation, which of the following scenarios best describes how the temperature of the gas changes during these processes?a.
The temperature of the gas decreases in both the isobaric and adiabatic transformations.
b.
The temperature of the gas drops during the isobaric transformation and rises during the adiabatic transformation.
c.
The temperature of the gas goes up during both the isobaric and adiabatic transformations.
d.
The temperature of the gas rises during the isobaric transformation and then falls during the adiabatic transformation.
e.
The temperature of the gas stays the same during the isobaric transformation and drops during the adiabatic transformation.

Two nearby sound sources produce sound waves with wavelengths λ₁ = 1.50 m and λ₂ = 1.55 m, respectively, in the same medium where the speed of sound is v = 330 m/s. Because of the slight difference in frequencies, audible interference creating beats occurs. Calculate the frequency of the beats resulting from this interference.
