19 cars in a circle at a boom box competition produce a 130 dB sound level at the center of the circle. What is the average sound level(dB) produced there by each, assuming interference effects can be neglected?
To find the average sound level produced by each car at the center of the circle, we need to divide the total sound level by the number of cars.
In this case, we know that there are 19 cars in the circle and the total sound level at the center is 130 dB. So, to find the average sound level, we can divide 130 dB by 19.
Average sound level = Total sound level / Number of cars
Let's calculate it:
Average sound level = 130 dB / 19 cars
Average sound level ≈ 6.84 dB per car
Therefore, each car produces an average sound level of approximately 6.84 dB at the center of the circle.
