Assuming that, in the center of a football stadium, measurements were taken to evaluate the average noise of a person shouting the word "goal" in different positions in the stands. The average value obtained, considering a large number of measurements, was 100 dB. Using this data, the noise produced by 10,000 people, randomly distributed in the stands, while simultaneously shouting the word "goal" was estimated. The estimated average value for the noise produced by these people, in the central position of this hypothetical stadium, was: A) 60 dB. B) 104 dB. C) 140 dB. D) 400 dB. E) 800 dB. ================== Follow us on social media: 📱 Instagram:   / thalesquirino   📱 Twitter: https://x.com/fisiquei Check out the complete playlist of ENEM 2025 solutions: 👉   • ENEM 2025 - Em uma comunidade rural, os mo...   Professor Thales Quirino Medeiros ================== #ENEM #physics #medicine #studies #education
