consider these scenarios. scenario 1 your ear is resting on the end of a metal bar that is struck by a drumstick about 7 meters away from your ear. scenario 2 you are about 7 meters away from a metal bar that is struck with a drumstick. the sound travels through the air to your ear. in which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? explain your answer.

Answer

Explanation:

Step1: Recall sound - speed in different media

Sound travels faster in solids than in gases. Metal is a solid and air is a gas.

Step2: Analyze each scenario

In Scenario 1, sound travels through the metal bar (a solid). In Scenario 2, sound travels through air (a gas). Since the speed of sound in a solid (metal) is much higher than the speed of sound in air, for the same distance (7 meters), the time taken for sound to travel through the metal bar will be less. The formula for time (t=\frac{d}{v}), where (d) is distance and (v) is speed. When (d) is the same, a higher (v) results in a lower (t).

Answer:

Scenario 1. Sound travels faster through solids (the metal bar in Scenario 1) than through gases (air in Scenario 2), so the sound will reach the ear in the least amount of time in Scenario 1.
