Sound waves need different media in order to travel. This travels by the movement of the atom transferred to another up to its destination. The speed of sound is greatest in solids since the molecules of solid are closely packed together, followed by liquid and they are slowest in gases.
a: The kinetic energy doubles. b: The kinetic energy quadruples. c: The kinetic energy is cut in half. Hopefully it’s clear how the formula can show you this.
