Astudent is bicycling north along main street to school. another student is timing the bicycling student in order to determine the average velocity. the bicycling student is 450 m away when the timer starts, and is 200 m away when the timer stops. if the student traveled the distance in 60 seconds, what is the students average velocity?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
