  2. The speed of sound in air at room temperature, 343 m/s, is approximately 767 miles per hour. Explanation: To calculate the speed of sound in miles per hour, we need to convert the speed from meters per second to miles per hour. There are 1609.34 meters in a mile and 3600 seconds in an hour. Therefore, to convert the speed from meters per second ...

  3. The equation for this is f = ( c c + v ) f 0 , where f is the observed frequency (pitch) of the sound, in Hertz c is the speed of sound, about 761 miles per hour, v is the speed of the sound source, in this case the car, in miles per hour f0 is the frequency of the sound when stationary Using a spectrum analyzer, we could determine the observed ...

  4. The speed of sound in air is 340 m/s. If the speed of a supersonic plane is twice the speed of sound, its speed is 2 × 340 m/s = 680 m/s. 1 hour is equal to 3,600 s. The speed expressed in m/h is: 680 m/s × (3,600 s/ 1 h) = 2.45 × 10⁶ m/h. 1 kilometer is equal to 1,000 meters. The speed expressed in km/h is:

  5. A. Distance of the lightning after 4 seconds = 744,000 miles. B. Distance of the lightning after n seconds = 186,000 * n. Step-by-step explanation: 1. Let's review the information given to us to answer the question correctly: Speed of lightning = 186,000 miles per second. Speed of sound = 750 miles per hour. 2. A.

  6. In unit time, the distance covered by any object is called speed. In mathematical term, Speed is express as S=D/T, where S=speed, D=distance, T= time. Given that, The speed of sound = 1225 kilometers per hour. The speed of sound = 340.277 meter/second. Also, the time after thunder heard = 5 seconds. To find distance, use formula distance ...

  7. The speed of sound is 1,088 feet per second. To convert this speed into miles per hour, we can use the conversion factors that 1 mile is equivalent to 5,280 feet, and there are 3,600 seconds in one hour: First, divide 1,088 by 5,280 to convert feet per second to miles per second. Then, multiply the result by 3,600 to convert from seconds to hours.

  8. The speed of sound is approximately 768 miles per hour. When an object travels faster than the speed of sound, it creates a sonic boom. Write an inequality that is true only for speeds (s) at which a moving object creates a sonic boom.

  9. The speed of sound through air is approximately 343 m/s. What is the speed in miles per hour What is the speed in miles per hour? 1 ft = 0.3048 m; 1 mile = 5280 feet

  10. To calculate the speed of the train, you can use the formula for the Doppler effect. By plugging in the given values, you can find the speed of the train in m/s. To convert the speed to miles per hour, multiply by the conversion factor 2.237. Explanation: The speed of the train can be calculated using the formula for the Doppler effect.

  11. Sound travels in air at about 750 miles per hour, which is approximately 1100 feet per second. Therefore after 2.5 seconds, the sound has travelled 2.5 * 1100 = 2750 feet. However, because this includes the path to the canyon wall and back, the actual distance to the canyon wall is 2750/2 = 1375 feet .
