![**Question 7:** When you hear a sonic boom, you often cannot see the plane that made it. Why is that?
**Explanation:**
A sonic boom is a loud sound that resembles an explosion. It is created when an object, such as an aircraft, travels through the air faster than the speed of sound, producing shock waves.
**Reasons why you often cannot see the plane:**
1. **Speed of Sound:** The plane is traveling faster than the speed of sound (approximately 343 meters per second or 1235 kilometers/hour at sea level). By the time you hear the sonic boom, the plane has already traveled some distance ahead of the point the sound was produced.
2. **Distance and Altitude:** High-altitude supersonic flights mean the aircraft is often located many kilometers above the ground, making it difficult to see from the ground.
3. **Sound Propagation:** Sound takes time to travel. The shock wave generated by a supersonic aircraft trails behind it, so by the time the sound reaches a listener on the ground, the aircraft is further along its path.
Understanding these concepts helps explain the lag between the visual presence and the auditory experience of witnessing high-speed aircraft.](https://content.bartleby.com/qna-images/question/a7f97488-1eec-40ae-956a-6f5afeb36900/6100ee21-b5a9-4844-b5fb-dcb620b25d29/rvea_thumbnail.png)

- 4. You are riding your bike down a hill at a speed of 7 m/s (~15 mph) and a stationary bell is ringing at the bottom of the hill with a pitch that has a frequency of 320 Hz. What wavelength would you measure for sound and what frequency would you hear? Use v = 340 m/s for the speed of sound. - wavearrow_forward99.. The standing waves in air in a pipe of length L that is open at both ends have a speed v. The frequencies of the three lowest harmonics are A) v/L, 2v/L, and 3v/L B) v/2L, v/L, and 3v/2L C) 2/2, 2, and 32/2 D) L/v, 2L/v, and 3L/v E) 2/3, 22/3, and 32/3arrow_forward3.) Consider a system like the one below. You want to measure the mass density of a cord. Understanding the relationship between wave speed and tension in a string, you decide to hang a 10 kg mass from the end of the string as shown. When you pluck the now tensioned string, you hear a note. You measure the frequency of the note with an app on your phone, finding it to be 130 Hz. What is the mass density of the string? 1 m 10 kg mgarrow_forward
