Question

Timothy speaks quietly toward a microphone that is 50-meters away. His voice reaches the microphone in 150 milliseconds. Timothy then shouts toward the microphone. How will shouting affect the amount of time it takes his voice to reach the microphone?

Answer 1

The volume of Timothy's voice does not affect the speed of sound; therefore, whether he speaks quietly or shouts, the time it takes for his voice to reach the microphone remains the same at 150 milliseconds.

Step-by-step explanation:

When Timothy speaks quietly or shouts toward the microphone, the speed of sound in air remains constant, unaffected by the volume of his voice. The speed of sound in air at standard conditions is approximately 340 m/s. Therefore, regardless of whether Timothy speaks quietly or shouts, the time it takes for his voice to reach the microphone 50 meters away will be consistent, given that the speed of sound and the distance don't change. The time can be calculated using the formula: time = distance / speed. Thus, when Timothy shouted, it did not affect the time it took for his voice to reach the microphone; it remained at 150 milliseconds.
