The correct Answer is:
To determine which option represents the loudest noise, we will analyze the sound levels produced by each of the given sources. ### Step-by-Step Solution: 1. **Understand the Question**: We need to identify which of the given options produces the loudest noise. The options are: - A) Jet at takeoff - B) Rocket launch - C) Humpback whale - D) Both A and B 2. **Analyze Each Option**: - **Jet at Takeoff**: A jet at takeoff produces a noise level of approximately **150 decibels** when measured from a distance of 25 meters. This level is intense enough to cause ear drum rupture. - **Rocket Launch**: A powerful rocket launch can produce a noise level of about **180 decibels**. This sound level is so high that it can cause vibrations that may damage spacecraft components. - **Humpback Whale**: Humpback whales, known for their vocalizations, can produce sounds reaching up to **230 decibels**. This makes them the loudest mammals on the planet. - **Both A and B**: This option suggests that both the jet at takeoff and rocket launch together produce a noise level that is louder than either alone, but we need to compare individual levels first. 3. **Compare the Decibel Levels**: - Jet at Takeoff: 150 dB - Rocket Launch: 180 dB - Humpback Whale: 230 dB 4. **Identify the Loudest Noise**: Among the three, the humpback whale produces the loudest noise at 230 decibels, which is significantly higher than both the jet at takeoff and the rocket launch. 5. **Select the Correct Option**: Based on the analysis, the correct answer is **C) Humpback whale**. ### Final Answer: The loudest noise is that of the **Humpback whale**. ---

The loudest insect is

The faintest sound the human ear can detect at a frequency of 1000 Hz correspond to an intensity of about 1.00xx10^-12(W)/(m^2) , which is called threshold of hearing. The loudest sounds the ear can tolerate at this frequency correspond to an intensity of about 1.00(W)/(m^2) , the threshold of pain. Detemine the pressure amplitude and displacement amplitude associated with these two limits. Take speed of sound =342(m)/(s) and density of air =1.20(kg)/(m^3)
