Final answer:
To carry energy on a sound wave more quickly through a metal medium, Asnsi should increase the temperature of the metal, as the increased kinetic energy of the particles allows for faster transmission of sound.
Step-by-step explanation:
To increase the speed at which energy on a sound wave is carried through a metal medium, Asnsi can increase the temperature of the metal. The speed of sound is not constant and can vary depending on a variety of factors, including the temperature of the medium through which the sound is traveling. As the temperature of a medium increases, the particles within that medium move faster due to an increase in kinetic energy, facilitating quicker transmission of sound. Options like increasing or decreasing the frequency will not change the speed of sound in the medium, but rather they would affect the characteristics of the sound wave itself.
