Using sonar in an ocean environment, you can determine how far below you are from reaching the bottom, or if something bigger picks up, say a whale, which in turns lets you know something big is beneath you. It helps determine how far you are under the water as well.
The black coffee, with a pH of 5 has a hydrogen ion concentration of 1 x 10^-5 mol/L. The tomato juice, with a pH of 4, has a hydrogen ion concentration of 1 x 10^-4 mol/L.
By taking the difference between the two respective concentrations, we can compute how much greater the concentration of hydrogen ions in the tomato juice is compared to the coffee.
Difference = (1 x 10^-4 mol/L) - (1 x 10^-5 mol/L)
Difference = 9 x 10^-5 mol/L
Thus, the tomato juice has a concentration of hydrogen ions that is 0.00009 mol/L greater than the the concentration of hydrogen ions in the black coffee.
