Tonya placed a disk of filter paper in each of the following solutions: disinfectant 1, disinfectant 2,
disinfectant 3, and distilled water. While the four disks
were soaking in their respective solutions, she streaked a
sterile mutrient agar dish with a culture of E. coli
bacteria. Then, she placed each disk carefully onto the
mutrient agar dish, placed the lid on the dish, taped it

Figure 19-4 shows how the nutrient agar dish looked on
Day I and Dar 4.

According the inverse square law, doubling the distance from the source of the sound, a speaker, for example, will drop the sound 6 db each time. if you were standing in the back of an auditorium, 32 feet away from a speaker not using any amplification, would you be able to hear a speaker clearly? why or why not?
