Problem 103

Two ships in a heavy fog are blowing their horns, both of which produce sound with a frequency of 175.0 Hz (Figure 1442). One ship is at rest; the other moves on a straight line that passes through the one at rest. If people on the stationary ship hear a beat frequency of 3.5 Hz, what are the two possible speeds and directions of motion of the moving ship?

Step-by-Step Solution:
Step 1 of 3

Chapter 17: Phases and Phase Changes  An ideal gas is one that is dilute enough, and far away enough from condensing, that the interactions between molecules can be ignored  If the volume of an ideal gas is held constant, we can find that the pressure increases with temperature o P = (constant)T  If the volume and temperature are kept constant, but more gas is added, the pressure will increase o P = (constant)N  If the temperature is constant and the volume decreases, the pressure increases o P = (constant) / V  Combining all of the above equations, we create the following equation o P = k (NT/V) o K = the Boltzmann constant = 1.38 x 10^(­23) J/K o PV=NkT
