← A sound detector by a road sends out 32.0 kHz. The echo from an approaching car, mixed with the sent sound, gives 3.20 kHz beats. Taking sound to travel at 340 m/s, how fast is the car?
The rms speed of the molecules of a diatomic ideal gas (rigid molecules) is 520 m/s. The gas expands slowly in an insulated cylinder until its volume is 32 times its first volume. What is the rms speed of its molecules now? →
