v = \frac{d}{t}\) \(v = 400 \div 1.2\) \(v = 333~m/s \ (3 \ sf)\) The accepted value for the speed of sound in air is 330 m/s. However, this experimental method is flawed as humans do not use stop ...

Although sound travels quite fast, it is still possible to measure its speed in air. To do this, you need to measure the time it takes a sound to travel a measured distance. To reduce errors ...

XB-1 demonstrator did not quite break the sound barrier during its seventh test flight but reached speed and altitude ...
