The Athletic Department at your school hosts a celebrity football game for which no tickets are sold but cash donations are welcome and expected. Since tickets are not collected, they are looking for a creative manner to get a good estimate of the number of fans attending the event. Before the day of the game, you stand in the middle of the field and record the sound intensity level of a friend midway up in the stands as 43.2 dB. Before the game starts, the announcer asks for a big round of applause and appreciation for participating celebrities and you record the sound intensity level as 97 dB. What is your estimate of the number of people attending the event

The number of people attending the events people

Explanation:

Generally total sound intensity is given as

Where

          is the total sound intensity

        is the signal level from each single source

        n is the number of source

        Substituting the given value

                  97 = 43.2 + 10log(n)

                  53.8 = 10log(n)

             log(n)  = 5.38

Raising both sides to the power of 10

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
